BaseVLayoutAdapterHelper
是基于阿里V-Layout的一个Android 简单的封装的通用Adapter。
引入
allprojects {
repositories {
maven { url 'https://jitpack.io' }
}
}
implementation 'com.github.lvtanxi:BaseVLayoutAdapterHelper:lasetversion'
使用
##（1）简单的数据绑定
VBaseAdapter<NormalModel> mBaseAdapter= new VBaseAdapter<NormalModel>(R.layout.item_main) {
@Override
protected void convert(VBaseHolderHelper helper, NormalModel model, int position) {
helper.setText(R.id.main_test, model.getTitle());
}
};
VirtualLayoutManager layoutManager = new VirtualLayoutManager(this);
mRecycler.setLayoutManager(layoutManager);
//总adapter
DelegateAdapter delegateAdapter = new DelegateAdapter(layoutManager, true);
delegateAdapter.addAdapter(mBaseAdapter.getTargetAdapter());
mRecycler.setAdapter(delegateAdapter);
在convert方法中完成数据,只需要简单的将Adapter继承VBaseAdapter，复写convert方法即可。省去了自己编写ViewHolder等大量的重复的代码。
如果想自定义ViewHolder。就请ViewHolder继承VBaseHolder，然后完成相应的方法复写。
##（2）多种ItemView
//设置LayoutManager
VirtualLayoutManager layoutManager = new VirtualLayoutManager(this);
mRecycler.setLayoutManager(layoutManager);
mRecycler.addItemDecoration(new SectionDecoration(R.layout.multilt_text_view));
//总adapter
DelegateAdapter delegateAdapter = new DelegateAdapter(layoutManager, true);
//各个adapter
bannerAdapter = new VBaseAdapter<BannerBean>(R.layout.recyc_banner) {
@Override
protected void convert(VBaseHolderHelper holder, BannerBean bannerBean, int position) {
Banner banner = holder.getView(R.id.banner);
banner.setImages(bannerBean.getPic_url());
//设置图片加载器
banner.setImageLoader(new ImageLoader() {
@Override
public void displayImage(Context context, Object o, ImageView imageView) {
Glide.with(context).load((String) o).centerCrop().diskCacheStrategy(DiskCacheStrategy.ALL).into
(imageView);
}
});
banner.start();
}
};
gridAdapter = new VBaseAdapter<GridBean>(R.layout.recyc_grid, getGridLayoutHelp()) {
@Override
protected void convert(VBaseHolderHelper holder, GridBean gridBean, int position) {
Glide.with(TaobaoActivity.this).load(gridBean.getPic_url()).centerCrop().diskCacheStrategy(DiskCacheStrategy.ALL).into(holder.getImageView(R.id.icon));
holder.setText(R.id.func, gridBean.getFunction());
}
};
delegateAdapter.addAdapter(bannerAdapter);
delegateAdapter.addAdapter(gridAdapter);
mRecycler.setAdapter(delegateAdapter);
V-Layout 中自带了一个DelegateAdapter，可以添加很多个不同的Adapter,我们只需要按照顺序添加不同的Adapter就可以了
##（3）分组itemView
mSectionedAdapter = new VBaseSectionedAdapter<Section2Model>(R.layout.multilt_text_view, R.layout.section_view)
.....
VBaseSectionedAdapter 主要是针对分组的情况来做出的处理,json的格式如: [data1:[{},{}],data2:[{},{}]]，需要重写convert和convertChildItem方法
##（4）添加HeaderView、FooterView
TextView header1Tv = new TextView(this);
mBaseAdapter.addHeaderView(header1Tv);
TextView footer1Tv = new TextView(this);
TextView footer2Tv = new TextView(this);
mBaseAdapter.addFooterView(footer1Tv);
mBaseAdapter.addFooterView(footer2Tv);
DelegateAdapter delegateAdapter = new DelegateAdapter(layoutManager, true);
delegateAdapter.addAdapter(mBaseAdapter.getTargetAdapter());
mRecycler.setAdapter(delegateAdapter);
这里比较纠结，因为V-Layout 已经实现了多Adapter模式，添加HeaderView、FooterView是否需要还有点考虑。类似装饰者模式，直接将原本的adapter传入，初始化一个HeaderAndFooterWrapper对象，然后调用相关API添加。 这里需要注意delegateAdapter.addAdapter(mBaseAdapter.getTargetAdapter())，使用了VHeaderFooterWrapper包装类(BaseAdapter中自动选择)
一些回调
mBaseAdapter.addOnItemClickListener(new OnItemClickListener<String>() {
@Override
public void onItemClick(View view, int i, String s) {
showToast(s);
}
});
mBaseAdapter.addOnItemChildClickListener(new OnItemChildClickListener() {
@Override
public void onItemChildClick(View view, int i) {
showToast("this is item : " + i+" say ,I'm a image ");
}
});
