没次当我们用RecyclerView是时候，不得不想到要添加点击事件， 头部，尾部，甚至分组繁琐代码烦恼，于是本人就无奈写了共用的adapter。
使用说明：
如，item资源为
R.layout.fragment_jiongtu_item_of_indexfregment
item里面有个imageview id为
R.id.iv_photo
private class JionTuAdapter extends BaseRecyclerViewAdapter { public JionTuAdapter(Context context) { super(context); } @Override protected int getContentResourse() { return R.layout.fragment_jiongtu_item_of_indexfregment; } @Override protected int[] setContentViewsIds() { return new int[]{R.id.iv_photo}; } int i = 0; @Override protected void onContentViewUpdate(BaseRecyclerViewAdapter adapter, View view, Object object) { //这个object就是ItemType.data ImageView photoView = (ImageView) adapter.getContentViewItemViewById(R.id.iv_photo); photoView.setImageResource((Integer) object); } }
这样，我就可以轻松实现了这个适配器！
然后，测试
recyclerView.setAdapter(adapter = new JionTuAdapter(getActivity()));//添加内容点击事件 adapter.setOnContentViewListener(new BaseRecyclerViewAdapter.OnContentViewListener() { @Override public void onClicked(View view, BaseRecyclerViewAdapter adapter, Object object) { Snackbar.make(view,"呵呵",Snackbar.LENGTH_SHORT).show(); } });List<JionTuAdapter.ItemType> list = new ArrayList<JionTuAdapter.ItemType>(); for(int i =0; i < 10;i++) { //把数据都添加到内容列表
list.add(new BaseRecyclerViewAdapter.ItemType(BaseRecyclerViewAdapter.ItemType.TYPE_CONTENT,R.drawable.ic_launcher));} adapter.update(list, false);//false代表不需要提前清空列表
如果要添加头部，类似上面的adapter，分别实现
getHeaderResourse
setHeaderViewsIds
onHeaderViewUpdate
三个方法。如果没有id，记得提供null
