基本上，您必须在OnLongClick方法中添加此代码

Basically you have to add this code in your OnLongClick method

 @Override
public boolean onLongClick(View view) {
    if (!mMultiSelector.isSelectable()) {
        ((AppCompatActivity) getActivity()).startSupportActionMode(mActionModeCallback); // (2)
        mMultiSelector.setSelectable(true);
        mMultiSelector.setSelected(MyViewHolder.this, true);
        return true;
    }
    return false;
}
