项目简介

为什么要写一个ActionBar？官方的和网上开源的那么多。

第一，先说说官方的。官方的在不同系统上的风格并不统一，自定义项太少，不能满足开发需求，所以才涌现了这么多的开源项目。

第二，网上开源的。网上的已有的，我发现的，用过的大部分都是直接封装一个固定样式的布局，或控制控件的显示隐藏，或动态添加需要的控件。但也仅限于自定义左右图标的和中间标题的个数和样式。如果要自定义ActionBar的背景呢？要让背景显示一个图片呢？要让图片延伸到状态栏下面呢？要让背景实现半透明高斯模糊效果呢？要限定按钮图标的大小呢？要自定义中间标题的背景呢？要显示一个搜索框呢？要让搜索框带有清空和搜索图标呢？要自定义搜索框样式呢？要在网络请求时显示一个Loading效果呢？等等这些需求都是无法满足的。而且我相信这样的需求不在少数。

也可能有可以实现的框架，只是我还没发现。

GitHub上Star那么多的框架都无法实现，这个就可以？

要说这个绝对可以实现，肯定是不可能的，但我相信可以实现市面上99%以上的需求。

哪里来的这么大的自信？还是先看看整个项目的层级结构吧。

整个ActionBarEx分为3个基本层级，具体负责功能和命名约定如下：

• BackgroundLayer 背景层，负责整个ActionBar背景的绘制，如实现半透明背景或图片背景或高斯模糊背景
• ActionBarLayer 主体层，是以下3个不分的统称：
  • StatusBar 系统状态栏占位，可控制单独显示一个背景色，可实现状态栏图片暗色和亮色模式切换
  • TitleBar 导航栏占位，用于显示标题图标按钮等，支持自定义布局样式，以实现复杂需求
  • BottomLine 底部分割线，可控制分割线颜色和高度
• ForegroundLayer 前景层，用于显示一些特殊的状态，如加载状态LoadingBar，支持自定义布局

别整这么多虚的，先看看疗效

呦吼，看着还不错呀，快告诉我怎么用？

别急呀，我再说说实现细节。

好好，别动手，有话好好说，你把这个规则长方体放下。。。

要说使用方式，还得再明确几个类

• ActionBarEx 这个就是上面说的封装好的分3个层级的基类
• ActionBarCommon 继承自ActionBarEx，标题栏布局为【图标-文字-标题文字-文字-图标】
• ActionBarSearch 继承自ActionBarEx，标题栏布局为【图标-文字-搜索框-文字-图标】
• ActionBarSuper 继承自ActionBarEx
  • 支持自定义主标题和副标题显示
  • 支持自定义标题位置居中或居左
  • 左右分别支持最多5个按钮
  • 支持精确自定义每个按钮的边距

集成方式

添加依赖

1. 在Project的build.gradle添加仓库地址

allprojects {
	repositories {
		...
		maven { url 'https://www.jitpack.io' }
	}
}

2. 在Model:app的build.gradle添加框架依赖

最新版本是多少，看下Releases

从2.2.9以后版本去除版本号前的v，引用时需要注意下。

从3.0.0版本开始分离了ActionBarEx和ActionBarCommon/Search。

从3.1.0版本新增ActionBarSuper

dependencies {
	// 完全引入
	implementation 'com.github.goweii:ActionBarEx:3.2.2'
	
	// 只引入ActionBarEx
	implementation 'com.github.goweii.ActionBarEx:actionbarex:3.2.2'
	// 引入ActionBarCommon/Search/Super，依赖于ActionBarEx
	implementation 'com.github.goweii.ActionBarEx:actionbarex-common:3.2.2'
}

简单需求只需要下面2步就可以了

这里用ActionBarCommon举个例子

1. 布局文件引用

<per.goweii.actionbarex.common.ActionBarCommon
    android:id="@+id/simple_action_bar_3"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="10dp"
    android:background="#ccffffff"
    app:ab_autoImmersion="false"
    app:ab_bottomLineColor="@color/line"
    app:ab_bottomLineHeight="0dp"
    app:ab_foregroundLayerLayout="@layout/loading_bar"
    app:ab_statusBarColor="@color/transparent"
    app:ab_statusBarMode="dark"
    app:ab_statusBarVisible="false"
    app:ab_titleBarHeight="48dp"
    app:abc_leftIconColor="@color/black"
    app:abc_leftIconRes="@mipmap/back"
    app:abc_leftText="返回"
	app:abc_leftTextPaddingLeft="0dp"
	app:abc_leftTextPaddingRight="0dp"
	app:abc_rightIconColor="@color/black"
	app:abc_rightIconRes="@mipmap/search"
	app:abc_rightText="确定"
    app:abc_rightTextPaddingLeft="0dp"
    app:abc_rightTextPaddingRight="0dp"
    app:abc_titleText="这个标题有点长我试试长标题什么样子"
	app:abc_titleTextMaxWidth="180dp" />

2. 代码中绑定事件

actionBarCommon.setOnLeftIconClickListener(new OnActionBarChildClickListener() {
    @Override
    public void onClick() {
    	Toast.makeText(context, "onLeftIconClick", Toast.LENGTH_SHORT).show()
    }
});

复杂一点的需求，需要自定义导航栏布局

使用起来是这个样子的

1. 自定义布局文件 title_bar_custom.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="48dp">
    
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="horizontal">

        <ImageView
            android:id="@+id/iv_back"
            android:layout_width="48dp"
            android:layout_height="48dp"
            android:padding="15dp"
            android:scaleType="fitCenter"
            android:src="@mipmap/back" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:gravity="center"
            android:text="自定义布局"
            android:textColor="@color/white"
            android:textSize="17sp" />

    </LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="right"
        android:orientation="horizontal">

        <ImageView
            android:layout_width="48dp"
            android:layout_height="48dp"
            android:padding="15dp"
            android:scaleType="fitCenter"
            android:src="@mipmap/download" />

        <ImageView
            android:layout_width="48dp"
            android:layout_height="48dp"
            android:padding="15dp"
            android:scaleType="fitCenter"
            android:src="@mipmap/delete" />

        <ImageView
            android:layout_width="48dp"
            android:layout_height="48dp"
            android:padding="15dp"
            android:scaleType="fitCenter"
            android:src="@mipmap/more" />

    </LinearLayout>

</RelativeLayout>

2. 引用布局

<per.goweii.actionbarex.ActionBarEx
    android:id="@+id/action_bar_ex"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="10dp"
    android:background="@drawable/title_bar_custom_bg"
    app:ab_bottomLineColor="@color/line"
    app:ab_bottomLineHeight="0dp"
    app:ab_foregroundLayerLayout="@layout/loading_bar"
    app:ab_statusBarColor="@color/transparent"
    app:ab_statusBarMode="dark"
    app:ab_statusBarVisible="48dp"
    app:ab_titleBarLayout="@layout/title_bar_custom" />

3. 代码中绑定事件

actionBarEx.getView(R.id.iv_back).setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
		finish();
    }
});

更加复杂的需求，可能需要自定义子类了

自定义子类需要下面三步，复写2个方法

1. initAttrs(AttributeSet attrs)：获取子类的自定义属性，注意不要忘了调用super.initAttrs(attrs);

2. inflateTitleBar()：初始化TitleBar导航栏布局

3. 自定义点击事件回调

举个例子吧

@Override
protected void initAttrs(AttributeSet attrs) {
    super.initAttrs(attrs);

    TypedArray typedArray = getContext().obtainStyledAttributes(attrs, R.styleable.ActionBarCommon);

    float titleTextMaxWidthDef = getContext().getResources().getDimension(R.dimen.title_bar_title_text_max_width_def);
    float iconPaddingDef = getContext().getResources().getDimension(R.dimen.title_bar_icon_padding_def);
    float textSizeDef = getContext().getResources().getDimension(R.dimen.title_bar_text_size_def);
    float textPaddingLeftDef = getContext().getResources().getDimension(R.dimen.title_bar_text_padding_left_def);
    float textPaddingRightDef = getContext().getResources().getDimension(R.dimen.title_bar_text_padding_right_def);
    float titleTextSizeDef = getContext().getResources().getDimension(R.dimen.title_bar_title_text_size_def);
    int iconColorDef = ContextCompat.getColor(getContext(), R.color.title_bar_icon_color_def);
    int textColorDef = ContextCompat.getColor(getContext(), R.color.title_bar_text_color_def);
    int titleTextColorDef = ContextCompat.getColor(getContext(), R.color.title_bar_title_text_color_def);

    leftTextClickToFinish = typedArray.getBoolean(R.styleable.ActionBarCommon_abc_leftTextClickToFinish, false);
    leftIconClickToFinish = typedArray.getBoolean(R.styleable.ActionBarCommon_abc_leftIconClickToFinish, false);
    leftText = typedArray.getString(R.styleable.ActionBarCommon_abc_leftText);
    leftTextSize = typedArray.getDimension(R.styleable.ActionBarCommon_abc_leftTextSize, textSizeDef);
    leftTextColor = typedArray.getColor(R.styleable.ActionBarCommon_abc_leftTextColor, textColorDef);
    leftTextPaddingLeft = (int) typedArray.getDimension(R.styleable.ActionBarCommon_abc_leftTextPaddingLeft, textPaddingLeftDef);
    leftTextPaddingRight = (int) typedArray.getDimension(R.styleable.ActionBarCommon_abc_leftTextPaddingRight, textPaddingRightDef);
    leftIconRes = typedArray.getResourceId(R.styleable.ActionBarCommon_abc_leftIconRes, 0);
    leftIconColor = typedArray.getColor(R.styleable.ActionBarCommon_abc_leftIconColor, iconColorDef);
    leftIconPadding = (int) typedArray.getDimension(R.styleable.ActionBarCommon_abc_leftIconPadding, iconPaddingDef);
    leftIconMarginLeft = (int) typedArray.getDimension(R.styleable.ActionBarCommon_abc_leftIconMarginLeft, 0);

    rightText = typedArray.getString(R.styleable.ActionBarCommon_abc_rightText);
    rightTextSize = typedArray.getDimension(R.styleable.ActionBarCommon_abc_rightTextSize, textSizeDef);
    rightTextColor = typedArray.getColor(R.styleable.ActionBarCommon_abc_rightTextColor, textColorDef);
    rightTextPaddingLeft = (int) typedArray.getDimension(R.styleable.ActionBarCommon_abc_rightTextPaddingLeft, textPaddingLeftDef);
    rightTextPaddingRight = (int) typedArray.getDimension(R.styleable.ActionBarCommon_abc_rightTextPaddingRight, textPaddingRightDef);
    rightIconRes = typedArray.getResourceId(R.styleable.ActionBarCommon_abc_rightIconRes, 0);
    rightIconColor = typedArray.getColor(R.styleable.ActionBarCommon_abc_rightIconColor, iconColorDef);
    rightIconPadding = (int) typedArray.getDimension(R.styleable.ActionBarCommon_abc_rightIconPadding, iconPaddingDef);
    rightIconMarginRight = (int) typedArray.getDimension(R.styleable.ActionBarCommon_abc_rightIconMarginRight, 0);

    titleText = typedArray.getString(R.styleable.ActionBarCommon_abc_titleText);
    titleTextSize = typedArray.getDimension(R.styleable.ActionBarCommon_abc_titleTextSize, titleTextSizeDef);
    titleTextColor = typedArray.getColor(R.styleable.ActionBarCommon_abc_titleTextColor, titleTextColorDef);
    titleTextMaxWidth = (int) typedArray.getDimension(R.styleable.ActionBarCommon_abc_titleTextMaxWidth, titleTextMaxWidthDef);

    typedArray.recycle();
}

@Override
protected View inflateTitleBar() {
    titleBarChild = (RelativeLayout) inflate(getContext(), R.layout.action_bar_title_bar_common, null);

    leftIconView = titleBarChild.findViewById(R.id.iv_left);
    leftTextView = titleBarChild.findViewById(R.id.tv_left);
    titleTextView = titleBarChild.findViewById(R.id.tv_title);
    rightTextView = titleBarChild.findViewById(R.id.tv_right);
    rightIconView = titleBarChild.findViewById(R.id.iv_right);

    LinearLayout.LayoutParams leftIconViewParams = (LinearLayout.LayoutParams) leftIconView.getLayoutParams();
    leftIconViewParams.leftMargin = leftIconMarginLeft;
    leftIconView.setLayoutParams(leftIconViewParams);
    if (leftIconRes > 0) {
        leftIconView.setVisibility(VISIBLE);
        leftIconView.setPadding(leftIconPadding, leftIconPadding, leftIconPadding, leftIconPadding);
        leftIconView.setImageResource(leftIconRes);
        leftIconView.setColorFilter(leftIconColor);
        if (leftIconClickToFinish) {
            leftIconView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    finishActivity();
                }
            });
        }
    } else {
        leftIconView.setVisibility(GONE);
    }

    if (!TextUtils.isEmpty(leftText)) {
        leftTextView.setVisibility(VISIBLE);
        leftTextView.setText(leftText);
        leftTextView.setTextColor(leftTextColor);
        leftTextView.setTextSize(TypedValue.COMPLEX_UNIT_PX, leftTextSize);
        leftTextView.setPadding(leftTextPaddingLeft, 0, leftTextPaddingRight, 0);
        if (leftTextClickToFinish) {
            leftTextView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    finishActivity();
                }
            });
        }
    } else {
        leftTextView.setVisibility(GONE);
    }

    titleTextView.setVisibility(VISIBLE);
    titleTextView.setText(titleText);
    titleTextView.setTextColor(titleTextColor);
    titleTextView.setTextSize(TypedValue.COMPLEX_UNIT_PX, titleTextSize);
    titleTextView.setMaxWidth(titleTextMaxWidth);

    LinearLayout.LayoutParams rightIconViewParams = (LinearLayout.LayoutParams) rightIconView.getLayoutParams();
    rightIconViewParams.rightMargin = rightIconMarginRight;
    rightIconView.setLayoutParams(rightIconViewParams);
    if (rightIconRes > 0) {
        rightIconView.setVisibility(VISIBLE);
        rightIconView.setPadding(rightIconPadding, rightIconPadding, rightIconPadding, rightIconPadding);
        rightIconView.setImageResource(rightIconRes);
        rightIconView.setColorFilter(rightIconColor);
    } else {
        rightIconView.setVisibility(GONE);
    }

    if (!TextUtils.isEmpty(rightText)) {
        rightTextView.setVisibility(VISIBLE);
        rightTextView.setText(rightText);
        rightTextView.setTextColor(rightTextColor);
        rightTextView.setTextSize(TypedValue.COMPLEX_UNIT_PX, rightTextSize);
        rightTextView.setPadding(rightTextPaddingLeft, 0, rightTextPaddingRight, 0);
    } else {
        rightTextView.setVisibility(GONE);
    }
    return titleBarChild;
}

好吧我承认，我只是复制了下ActionBarCommon的实现代码，不过流程就是这么个流程，还是很简单的。

哎，等等，前景层怎么用呢？

厉害了，想跳过去，都被你发现了。

看下前面自定义导航栏布局中是不是有这么一句

app:ab_foregroundLayerLayout="@layout/loading_bar"

那这个布局长什么样子呢？

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout  xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:visibility="gone"
    android:layout_height="50dp">

    <me.zhanghai.android.materialprogressbar.MaterialProgressBar
        android:id="@+id/loading_bar"
        style="@style/loading_bar"
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:layout_gravity="bottom"
        android:indeterminate="true"
        app:mpb_progressStyle="horizontal"
        app:mpb_useIntrinsicPadding="false" />

</FrameLayout>

这个其实就是一个1dp高的ProgressBar，用来显示加载中效果

在代码中这样使用就可以了

actionBarEx.getForegroundLayer().setVisibility(View.VISIBLE);
actionBarEx.getForegroundLayer().setVisibility(View.GONE);

是不是很简单？

实现细节

好了，下面上干货。还是从整个层级划分开始说起吧。

先从布局结构重新看下层级划分

• FrameLayout（ActionBarEx本身，继承自FrameLayout）
  • ImageView或者自定义布局（背景层BackgroundLayer）
  • LinearLayout（主体层ActionBar）
    • View（状态栏StatusBar）
    • FrameLayout（标题栏TitleBar）
    • View（底部分割线BottomLine）
  • 自定义布局（前景层ForegroundLayer）

这样是不是对整个结构有了一个更清晰的认识。

从代码上看主要的两个功能

• ActionBarEx（自定义控价，负责显示布局）
• StatusBarUtils（负责系统状态栏的沉浸和图标亮色暗色模式切换）

来先看下ActionBarEx的自定义过程

先看下构造方法都干了那些事

public ActionBarEx(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
    this.mContext = context;
    mDisplayInfoUtils = DisplayInfoUtils.getInstance(context);
    mStatusBarHeight = mDisplayInfoUtils.getStatusBarHeight();
    initAttrs(attrs);
    makeImmersion();
    initView();
}

可以看到初始化了一个DisplayInfoUtils对象，获取了下系统状态栏的高度。

然后调用了3个方法，下面一个一个看下：

initAttrs(AttributeSet attrs)

主要为获取了自定义属性，设置默认值。这都是自定义View的常规操作。

protected void initAttrs(AttributeSet attrs) {
    TypedArray typedArray = mContext.obtainStyledAttributes(attrs, R.styleable.ActionBarEx);

    float titleBarHeightDef = mContext.getResources().getDimension(R.dimen.title_bar_height_def);
    float bottomLineHeightDef = mContext.getResources().getDimension(R.dimen.bottom_line_height_def);
    int bottomLineColorDef = ContextCompat.getColor(mContext, R.color.bottom_line_color_def);
    int statusBarColorDef = ContextCompat.getColor(mContext, R.color.status_bar_color_def);

    mAutoImmersion = typedArray.getBoolean(R.styleable.ActionBarEx_ab_auto_immersion, true);
    mBackgroundLayerLayoutRes = typedArray.getResourceId(R.styleable.ActionBarEx_ab_background_layer_layout, 0);
    mBackgroundLayerImageRes = typedArray.getResourceId(R.styleable.ActionBarEx_ab_background_layer_image_res, 0);
    mStatusBarVisible = typedArray.getBoolean(R.styleable.ActionBarEx_ab_status_bar_visible, true);
    mStatusBarDarkMode = typedArray.getInt(R.styleable.ActionBarEx_ab_status_bar_mode, STATUS_BAR_MODE_LIGHT) == STATUS_BAR_MODE_DARK;
    mStatusBarColor = typedArray.getColor(R.styleable.ActionBarEx_ab_status_bar_color, statusBarColorDef);
    mTitleBarLayoutRes = typedArray.getResourceId(R.styleable.ActionBarEx_ab_title_bar_layout, 0);
    mTitleBarHeight = (int) typedArray.getDimension(R.styleable.ActionBarEx_ab_title_bar_height, titleBarHeightDef);
    mBottomLineHeight = (int) typedArray.getDimension(R.styleable.ActionBarEx_ab_bottom_line_height, bottomLineHeightDef);
    mBottomLineColor = typedArray.getColor(R.styleable.ActionBarEx_ab_bottom_line_color, bottomLineColorDef);
    mForegroundLayerLayoutRes = typedArray.getResourceId(R.styleable.ActionBarEx_ab_foreground_layer_layout, 0);

    typedArray.recycle();
}

makeImmersion()

看名字可以知道是设置沉浸模式，先贴代码：

private void makeImmersion() {
    if (!mAutoImmersion) {
        return;
    }
    Activity activity = getActivity();
    if (activity == null) {
        return;
    }
    setSystemStatusBar(activity);
    hintSystemActionBar(activity);
}

看最下面2行，分别设置了系统沉浸状态栏和隐藏一同自带的导航栏。

具体如何实现状态栏沉浸的，我就不多介绍了，都是百度的一些零零散散的方法，和看GitHub上一些大神的代码，针对小米魅族VIVO做了适配。并不能保证所有系统都有效。如果你有更好的适配方案，欢迎讨论，或者你可以让mAutoImmersion=false来关闭自动适配，去Activity实现自己的方法

initView()

这个方法是本项目的重点，但很简单，没什么难的。

private void initView() {
    // 1 初始化BackgroundLayer
    // 1.1 初始化背景图
    if (mBackgroundLayerLayoutRes > 0){
        mBackgroundLayer = inflate(getContext(), mBackgroundLayerLayoutRes, null);
        mBackgroundLayer.setLayoutParams(makeLayerLayoutParams());
        addView(mBackgroundLayer);
    } else {
        if (mBackgroundLayerImageRes > 0) {
            ImageView actionBarImageView = new ImageView(mContext);
            actionBarImageView.setLayoutParams(makeLayerLayoutParams());
            actionBarImageView.setImageResource(mBackgroundLayerImageRes);
            actionBarImageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
            addView(actionBarImageView);
        }
    }

    // 2 初始ContentLayer（ActionBar）
    mActionBar = (LinearLayout) inflate(getContext(), R.layout.action_bar, null);
    mActionBar.setLayoutParams(makeLayoutParamsWithHeight(getActionBarHeight()));
    // 2.1 初始StatusBar
    mStatusBar = mActionBar.findViewById(R.id.status_bar);
    mStatusBar.setLayoutParams(makeLayoutParamsWithHeight(mStatusBarHeight));
    mStatusBar.setBackgroundColor(mStatusBarColor);
    mStatusBar.setVisibility(mStatusBarVisible ? VISIBLE : GONE);
    // 2.2 初始TitleBar
    mTitleBar = mActionBar.findViewById(R.id.title_bar);
    mTitleBar.setClickable(true);
    mTitleBar.setFocusable(true);
    mTitleBar.setFocusableInTouchMode(true);
    mTitleBar.setLayoutParams(makeLayoutParamsWithHeight(mTitleBarHeight));
    mTitleBarChild = inflateTitleBar();
    if (mTitleBarChild != null) {
        mTitleBar.addView(mTitleBarChild);
    }
    // 2.3 初始BottomLine
    mBottomLine = mActionBar.findViewById(R.id.bottom_line);
    mBottomLine.setLayoutParams(makeLayoutParamsWithHeight(mBottomLineHeight));
    mBottomLine.setBackgroundColor(mBottomLineColor);
    addView(mActionBar);

    // 3 初始ForegroundLayer
    if (mForegroundLayerLayoutRes > 0) {
        mForegroundLayer = inflate(getContext(), mForegroundLayerLayoutRes, null);
        mForegroundLayer.setLayoutParams(makeLayerLayoutParams());
        addView(mForegroundLayer);
    }
}

这里又有一个inflateTitleBar()方法，就是为了继承自定义而加的，它是这样实现的

protected View inflateTitleBar() {
    if (mTitleBarLayoutRes > 0) {
        return inflate(getContext(), mTitleBarLayoutRes, null);
    }
    return null;
}

然后是。？还有然后？哦，没了

一共就干了这么点事，没有实现任何效果，完全是一个空架子。是的，任何效果都需要自定义。

这个ActionBarEx只是划分了下导航栏的层级，限定了下各层级的功能。

当然每个项目肯定都有一个固定风格的设计，不可能每次使用都在布局中添加一个ActionBarEx，再引用一个自定义布局，再在代码中getView拿到控件初始化和绑定事件。稍微复杂点的肯定都是要自定义子类封装的，具体可以参考上面的自定义子类或者直接参考SimpleActionBar或者SearchActionBar的实现。
