PopupWindow内的RecyclerView，单击项目后如何关闭？

Question

我在PopupWindow内有一个recyclerview，单击回收台内的某个项目后如何关闭PopupWindow？

public SelectBucketMenu(Context context, ArrayList<String> mBucketNames, ArrayList<String> mImagesBucket) {
        super(context);
        this.mContext = context;
        this.mBucketNames = mBucketNames;
        this.mImagesBucket = mImagesBucket;

        setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
        setOutsideTouchable(true);
        setFocusable(true);
        //Need set windowlayout for API 19 otherwise window won't appear
        setWindowLayoutMode(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);

        setupView();
    }

    private void setupView(){
        View view = LayoutInflater.from(mContext)
                .inflate(R.layout.popupmenu_selectbucket, null);
        ButterKnife.bind(this, view);
        setContentView(view);

        mAdapter = new SelectBucketAdapter(mContext, mBucketNames, mImagesBucket);
        mRecycler.setLayoutManager(new LinearLayoutManager(mContext));
        mRecycler.setAdapter(mAdapter);
    }

并且在ViewHolder中，我实现了onClick方法：

public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {


        @BindView(R.id.vh_selectbucketmenu_rellayout) RelativeLayout vhLayout;

        int mPosition;
        public ViewHolder(@NonNull View itemView) {
            super(itemView);
            ButterKnife.bind(this, itemView);
            vhLayout.setOnClickListener(this);
        }

        @Override
        public void onClick(View view) {
            mPosition = getAdapterPosition();

            //How to dismiss the menu?
        }
    }

Answer 1

有两种方法可以做到：1）您可以使用interface散布对话框2）您可以在适配器构造函数中发送对话框对象，然后在适配器中设置click方法后再设置其dialog.dismiss();

Answer 2

您可以将ViewHolder用作SelectBucketMenu中的内部类，假设SelectBucketMenu具有如下的dismiss（）函数：
