Android: 如何从 LongClick 方法中排除 CardView 的复选框？

Question

我在 ReyclerView 列表中有 CardView。我进行了设置，以便 CardView 上的 LongClick 启动 DialogFragment。 CardView 上有一个复选框，我想从 LongClick 方法中排除该复选框；也就是说，如果复选框被长按，我不想加载 DialogFragment。我将 'android:longClickable="false"' 和 'android:focusable="false"' 添加到 CardView 布局，但这没有用。我将如何实现？

Adapter file:    
...
public static class ListViewHolder extends RecyclerView.ViewHolder implements View.OnLongClickListener {

    CardView singleCardView;

    TextView cardBlankText1;
    TextView cardBlankTextNumstotal;
    CheckBox chkSelected;
    TextView cardBlankText2;
    TextView cardBlankText4;
    TextView cardBlankText5A;
    TextView cardBlankText5B;
    TextView cardBlankText6;
    TextView cardBlankText7;
    TextView cardBlankText8;

    public ListViewHolder(View itemView) {
        super(itemView);

        itemView.setOnLongClickListener(this);
        singleCardView = (CardView) itemView.findViewById(R.id.singlecard_view1);

        chkSelected = (CheckBox) itemView.findViewById(R.id.chkSelected);
        cardBlankText1 = (TextView) itemView.findViewById(R.id.cardBlankText1);
        cardBlankTextNumstotal = (TextView) itemView.findViewById(R.id.cardBlankTextNumstotal);
        cardBlankText2 = (TextView) itemView.findViewById(R.id.cardBlankText2);
        cardBlankText4 = (TextView) itemView.findViewById(R.id.cardBlankText4);
        cardBlankText5A = (TextView) itemView.findViewById(R.id.cardBlankText5A);
        cardBlankText5B = (TextView) itemView.findViewById(R.id.cardBlankText5B);
        cardBlankText6 = (TextView) itemView.findViewById(R.id.cardBlankText6);
        cardBlankText7 = (TextView) itemView.findViewById(R.id.cardBlankText7);
        cardBlankText8 = (TextView) itemView.findViewById(R.id.cardBlankText8);

        chkSelected.setOnLongClickListener(new View.OnLongClickListener() {
            @Override
            public boolean onLongClick (View view){
                return true;
            }
        });
    } 
    @Override
    public boolean onLongClick(View view) {
        clickListener.onItemLongClick(getAdapterPosition(), view);
        return false;
    }
}

public void setonItemClickListener(ClickListener  clickListener) {
    ListAdapter.clickListener = clickListener;
}

public interface ClickListener {
    void onItemLongClick(int position, View view);
}

获取复选框并在其上设置一个空的 OnLongClickListener。这将消耗事件并阻止父 CardView 获取它：

View checkbox = container.findViewById(R.id.checkbox);

checkbox.setOnLongClickListener(new View.OnLongClickListener() {
    @Override
    public boolean onLongClick(View view) {
      //make sure to return true here so the parent cardview doesn't get the event.
      return true;
    }
});
