java - ListItem 不响应 Android ArrayAdapter 中的 clickEvents？

Question

“当用户单击描述 TextView 和 Like ImageButton 时，我尝试创建 Toast 消息。但 list_item 未响应触摸事件”

“我询问了很多其他人关于改变焦点的问题，但他们都没有效果”

“我想让 list_item 响应点击事件并显示 toast 消息..请帮忙..提前致谢!”

Answer 1

这可能是因为您试图在 ListView 的项目单击监听器内执行单击。

您可以通过为 ListView 创建自定义适配器来修复它。 Customer ListView Adapter

创建此自定义适配器后，您可以获取description和loveBtn的引用，并对其进行点击操作。

你的适配器的 getView() 代码将是这样的 -

   @Override
   public View getView(int position, View convertView, ViewGroup parent) {
      if(convertView==null) {
         LayoutInflater layoutInflater = LayoutInflater.from(context);
         convertView=layoutInflater.inflate(R.layout.list_row, null);

         TextView description=convertView.findViewById(R.id.eventDesc);
         Button loveBtn=convertView.findViewById(R.id.loveButton);

      }

         description.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    if (!TextUtils.isEmpty(mEventUrl)) {
                        Intent openLinkInBrowser = new Intent(Intent.ACTION_VIEW);
                        openLinkInBrowser.setData(Uri.parse(mEventUrl));
                        startActivity(openLinkInBrowser);
                    } else {
                        Toast.makeText(MainActivity.this, "Links are not provided", Toast.LENGTH_SHORT).show();
                    }
                }
            });

           loveBtn.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    if (status) {
                        Toast.makeText(MainActivity.this, "Liked", Toast.LENGTH_SHORT).show();
                        mEventsObject.setHeartLiked(true);
                    } else {
                        Toast.makeText(MainActivity.this, "Disliked", Toast.LENGTH_SHORT).show();
                        mEventsObject.setHeartLiked(false);
                    }
                }
            });

      return convertView;
   }
