在 MainActivity 中
RecyclerView recyclerView =(RecyclerView) findViewById(R.id.recyclerview);
recyclerView.addOnItemTouchListener(new RecyclerTouchListener(getActivity(),recyclerView, new RecyclerTouchListener.ClickListener() {
@Override
public void onLongClick(View child, int childPosition) {
}
@Override
public void onClick(View child, int childPosition) {
}
}));
