RecyclerView的基本用法与四种数据展示(listview,griderview,单行,多行)

//listview点击
public void getListView(View view) {
recyclerView.setLayoutManager(new LinearLayoutManager(Main2Activity.this,OrientationHelper.VERTICAL,false));
// recyclerAdapter.notifyDataSetChanged();

}//grideview点击事件public void getGrideView(View view) {recyclerView.setLayoutManager(new GridLayoutManager(Main2Activity.this,3));}

//单行

public void getDanHang(View view) {
recyclerView.setLayoutManager(new LinearLayoutManager(Main2Activity.this,OrientationHelper.HORIZONTAL,false));
}
//多行
public void getDuoHang(View view) {
recyclerView.setLayoutManager(new GridLayoutManager(Main2Activity.this,3,OrientationHelper.HORIZONTAL,false));
}
