gradle依赖

dependencies {
    implementation 'com.classic.adapter:commonadapter:2.0'
    implementation 'com.android.support:recyclerview-v7:27.0.2'
}

开始使用

ListView/GridView 使用示例

List<News> newsList = ...;
//单布局文件
listView = (ListView) findViewById(R.id.listview);
listView.setAdapter(new CommonAdapter<News>(context,
    //item布局文件
    R.layout.item_none_picture, newsList ) {
    @Override public void onUpdate(BaseAdapterHelper helper, News item, int position) {
        //BaseAdapterHelper详细用法，见下方

        helper.setText(R.id.xxx, item.getTitle())
               //1.如果已配置全局图片加载，这里可以不设置。全局图片加载配置见下方
               //2.有些项目可能使用多个图片加载库，这里可以针对当前adapter设置图片加载的实现方式，详见demo
              .setImageLoad(new GlideImageLoad())
              .setImageUrl(R.id.xxx,item.getCoverUrl());
    }
});

//多布局文件
private final class MultipleLayoutAdapter extends CommonAdapter<News>{

    public MultipleLayoutAdapter(Context context, int layoutResId, List<News> data) {
        super(context, layoutResId, data);
    }
    //多种布局重写此方法即可
    @Override public int getLayoutResId(News item, int position) {
        int layoutResId = -1;
        switch (item.getNewsType()){
            case News.TYPE_NONE_PICTURE: //布局样式一
                layoutResId = R.layout.item_none_picture;
                break;
            case News.TYPE_SINGLE_PICTURE: //布局样式二
                layoutResId = R.layout.item_single_picture;
                break;
            case News.TYPE_MULTIPLE_PICTURE: //布局样式三
                layoutResId = R.layout.item_multiple_picture;
                break;

            更多的布局样式 ...
        }
        return layoutResId;
    }

    @Override public void onUpdate(BaseAdapterHelper helper, News item, int position) {
        switch (item.getNewsType()){
            case News.TYPE_NONE_PICTURE: //布局样式一
                helper.setText(R.id.xxx, item.getTitle())
                      .setImageUrl(R.id.xxx,item.getCoverUrl());
                break;
            case News.TYPE_SINGLE_PICTURE: //布局样式二
                helper.setText(R.id.xxx, item.getTitle())
                      .setImageUrl(R.id.xxx,item.getCoverUrl());
                break;
            case News.TYPE_MULTIPLE_PICTURE: //布局样式三
                helper.setText(R.id.xxx, item.getTitle())
                      .setImageUrl(R.id.xxx,item.getCoverUrl());
                break;

            更多的布局样式 ...
        }
    }
}

RecyclerView 使用示例

使用 DiffUtil 高效更新 RecyclerView 示例代码，点这里

List<News> newsList = ...;
//单布局文件
recyclerView = (RecyclerView) findViewById(R.id.recyclerview);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setHasFixedSize(true);
recyclerView.setItemAnimator(new DefaultItemAnimator());
newsAdapter = new NewsAdapter(this, R.layout.item_none_picture, newsList);
recyclerView.setAdapter(newsAdapter);

private class NewsAdapter extends CommonRecyclerAdapter<News>{

    public NewsAdapter(Context context, int layoutResId, List<News> data) {
        super(context, layoutResId, data);
    }

    @Override public void onCreate(RecyclerView.ViewHolder viewHolder, BaseAdapterHelper helper) {
        // ViewHolder创建时回调
    }

    @Override public void onUpdate(BaseAdapterHelper helper, News item, int position) {
        helper.setText(R.id.xxx, item.getTitle())
              .setImageUrl(R.id.xxx,item.getCoverUrl());
    }
}

//多布局文件
private final class MultipleLayoutAdapter extends CommonRecyclerAdapter<News>{

    public MultipleLayoutAdapter(Context context, int layoutResId, List<News> data) {
        super(context, layoutResId, data);
    }

    @Override public void onCreate(RecyclerView.ViewHolder viewHolder, BaseAdapterHelper helper) {
        // ViewHolder创建时回调
    }

    //多种布局重写此方法即可
    @Override public int getLayoutResId(News item, int position) {
        int layoutResId = -1;
        switch (item.getNewsType()){
            case News.TYPE_NONE_PICTURE: //布局样式一
                layoutResId = R.layout.item_none_picture;
                break;
            case News.TYPE_SINGLE_PICTURE: //布局样式二
                layoutResId = R.layout.item_single_picture;
                break;
            case News.TYPE_MULTIPLE_PICTURE: //布局样式三
                layoutResId = R.layout.item_multiple_picture;
                break;

            更多的布局样式 ...
        }
        return layoutResId;
    }

    @Override public void onUpdate(BaseAdapterHelper helper, News item, int position) {
        switch (item.getNewsType()){
            case News.TYPE_NONE_PICTURE: //布局样式一
                helper.setText(R.id.xxx, item.getTitle())
                      .setImageUrl(R.id.xxx,item.getCoverUrl());
                break;
            case News.TYPE_SINGLE_PICTURE: //布局样式二
                helper.setText(R.id.xxx, item.getTitle())
                      .setImageUrl(R.id.xxx,item.getCoverUrl());
                break;
            case News.TYPE_MULTIPLE_PICTURE: //布局样式三
                helper.setText(R.id.xxx, item.getTitle())
                      .setImageUrl(R.id.xxx,item.getCoverUrl());
                break;

            更多的布局样式 ...
        }
    }
}

RecyclerView 点击事件

commonRecyclerAdapter.setOnItemClickListener(this) // 设置 item 点击事件
                     .setOnItemLongClickListener(this) // 设置 item 长按事件
                     // 设置 Child view 的点击、长按、Touch事件(方式一)
                     // OnChildViewClickListener 、 OnChildViewLongClickListener 、 OnChildViewTouchListener
                     .addChildViewListener(R.id.viewId, listener);

BaseAdapterHelper 使用示例

helper.setText(R.id.viewId, text)
      .setTag(R.id.viewId, objectTag)
      .setAlpha(R.id.viewId, 0.6f)
      .setBackgroundColor(R.id.viewId, R.color.colorResId)
      .setBackgroundRes(R.id.viewId, R.drawable.drawableResId)
      .setChecked(R.id.viewId, true)
      .setImageBitmap(R.id.viewId, bitmap)
      .setImageDrawable(R.id.viewId, drawable)
      .setImageResource(R.id.viewId, R.drawable.drawableResId)
      .setImageUrl(R.id.viewId, url)
      .setProgress(R.id.viewId, progress)
      .setProgress(R.id.viewId, progress, max)
      .setRating(R.id.viewId, rating)
      .setRating(R.id.viewId, rating, max)
      .setTextColor(R.id.viewId, R.color.colorResId)
      .setTextColorRes(R.id.viewId, R.color.colorResId)
      .setTextColorRes(R.id.viewId, R.color.colorResId, theme)
      //TextView添加超链接，更多属性参考：android.text.util.Linkify#addLinks(TextView text, int mask)
      .addLinks(R.id.viewId, Linkify.ALL)
      //效果同上
      .addAllLinks(R.id.viewId)
      //单个TextView设置Typeface
      .setTypeface(R.id.viewId, typeface)
      //多个TextView设置Typeface
      .setTypeface(typeface, R.id.xxx1, R.id.xxx2, R.id.xxx3, ...)
      .setVisible(R.id.viewId, View.VISIBLE)
      //ProgressBar设置Max
      .setMax(R.id.viewId, max)
      //ListView、RecyclerView设置adapter
      .setAdapter(R.id.viewId, adapter)
      // 设置 Child view 的点击、长按、Touch事件(方式二)
      .setOnTouchListener(R.id.viewId, onTouchListener)
      .setOnClickListener(R.id.viewId, onClickListener)
      .setOnLongClickListener(R.id.viewId, onLongClickListener)
      .setOnItemClickListener(R.id.viewId, onItemClickListener)
      .setOnItemLongClickListener(R.id.viewId, onItemLongClickListener)
      .setOnItemSelectedClickListener(R.id.viewId, onItemSelectedListener);

//获取item的convertView
View convertView = helper.getView();

//如果上面的属性不够用,可以通过getView(viewId)拿到View,然后进行属性设置
View childView = helper.getView(R.id.viewId);

配置全局图片加载的实现类

public class YourApplication extends Application {

    @Override public void onCreate() {
        super.onCreate();

        ...

        ImageLoad imageLoadImpl = new GlideImageLoad();
        Adapter.config(new Adapter.Builder().setImageLoad(imageLoadImpl));
    }
}

自定义图片加载

public class YourXXX implements ImageLoad {

    @Override public void load(Context context, ImageView imageView, String imageUrl) {

        //使用Glide加载图片
        Glide.with(context).load(imageUrl).into(imageView);

        or

        //使用Picasso加载图片
        Picasso.with(context).load(url).into(imageView);

        or

        Fresco
        Android-Universal-Image-Loader
        自定义
        ...
    }
}

常用的数据操作

//CommonAdapter、CommonRecyclerAdapter都实现了IData接口，里面包含了一些常用的数据操作

void add(T elem);

void addAll(List<T> elem);

void set(T oldElem, T newElem);

void set(int index, T elem);

void remove(T elem);

void remove(int index);

void replaceAll(List<T> elem);

boolean contains(T elem);

void clear();
