Question

我要完成的工作是在RecyclerView行内为ImageView创建一个侦听器。

此代码已经在工作，但这不是我想要的解决方案，因为您需要双击 ImageView，然后才能获得所需的结果。

// row click listener
recyclerView.addOnItemTouchListener(new RecyclerTouchListener(getApplicationContext(), recyclerView, new RecyclerTouchListener.ClickListener() {

    @Override
    public void onClick(View view, final int position) {

        ImageView viewContent = (ImageView)view.findViewById(R.id.btnViewContent);
        ImageView deleteContent = (ImageView)view.findViewById(R.id.btnDeleteContent);

        viewContent.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(getApplicationContext(), "VIEW CONTENT", Toast.LENGTH_SHORT).show();
            }
        });

        deleteContent.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(getApplicationContext(), "DELETE CONTENT", Toast.LENGTH_SHORT).show();
            }
        });

    }

    @Override
    public void onLongClick(View view, int position) {}

}));

有什么想法可以将其转换为单击解决方案吗？咨询甚至是一条评论都对我有很大帮助。

Answer 1

这不是我们朋友建议的正确方法，在滚动过程中一次又一次地对onBindViewHolder进行校正，因此在其中添加侦听器不是最佳实践。

最好的方法是按照我的建议将其添加到ViewHolder中。检查上面的答案。

Then there is no need to implement recyclerView.addOnItemTouchListener ,  inside Viewholder just add clicklistener on the view(image) you want below is the example for reference.

 ` public static class HeaderViewHolder extends RootViewHolder {

        @BindView(R.id.cardview)
        CardView cardview;
        @BindView(R.id.main_container)
        LinearLayout main_container;
        @BindView(R.id.music_cardview)
        CardView music;
        @BindView(R.id.shabad_cardview)
        CardView shabadvaani;
        @BindView(R.id.news_cardview)
        CardView news;
        @BindView(R.id.donate_cardview)
        CardView donate;
        @BindView(R.id.bs_cardview)
        CardView bs;
        @BindView(R.id.bl_cardview)
        CardView bl;
        @BindView(R.id.bng_cardview)
