java - Onclick Recycler View 中的按钮不起作用

Question

当点击 Button 时，它应该打开浏览器，但它没有到达启动 Activity 的代码

public class RecyclerViewAdapterDetailsScreen extends RecyclerView.Adapter<RecyclerViewAdapterDetailsScreen.ViewHolder> {

    private Context mContext;
    private int numberOfButtons;
    private String [] trailers;

    public RecyclerViewAdapterDetailsScreen(Context mContext, int numberOfButtons,String [] trailers) {
        this.numberOfButtons=numberOfButtons;
        this.mContext = mContext;
        this.trailers=trailers;
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {

        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.layout_listitem2, parent, false);
        ViewHolder holder = new ViewHolder(view);

        return holder;
    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, final int position) {

        /*** Toast.makeText(mContext, trailers[position]+" From OnBindViewHolder", Toast.LENGTH_SHORT).show();
         *   Toast is working from Here but no sign from on click
         */

        holder.parentlayout.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view)
            {

                // TOAST IS NOT WORKING SO THE CODE DOESNT gett HERE...............................

                Toast.makeText(mContext, trailers[position], Toast.LENGTH_SHORT).show();
                Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(trailers[position]));
                mContext.startActivity(browserIntent);

            }
        });

    }

    @Override
    public int getItemCount() {
        return trailers.length;
    }

    public class ViewHolder extends RecyclerView.ViewHolder
    {
        Button mbutton;
        RelativeLayout parentlayout;

        public ViewHolder(@NonNull View itemView) {
            super(itemView);
            mbutton=itemView.findViewById(R.id.button);
            parentlayout = itemView.findViewById(R.id.parent_layout2);
        }
    }
}

它必须进入 onClick 并开始新的 Activity 以打开 youtube 应用程序或浏览器，如果您想查看任何缺少的代码告诉我

Answer 1

您的代码是完美的。这里只有一个问题，您的 parent_layout2 没有获得点击事件，它被 child (按钮)使用。根据 Android 定义， child 优先。

只需将父级宽度更新为 match_parent。它会起作用。我刚刚测试了您的代码。

这是你更新后的 xml

layout_listitem2.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/parent_layout2"
    >

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/button"
        />

</RelativeLayout>

快乐编码。如果有效请投票。

谢谢
