Question

我正在尝试使用clicklistener来捕获我的项目的点击次数在我的Recycleview中，但我的大部分视图都是由图像构成的，当我按下图像时它没有注册，只有当我按下图像外我该如何修复它以便所有卡片视图都能捕获到点击？或者每次按下图片时将焦点设置到卡片上？

这是我的适配器：

public class cardsAdapter extends RecyclerView.Adapter<cardsAdapter.MyViewHolder> {

    private Context mContext;
    private List<CardModel> albumList;

    public class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        public TextView title, count;
        public ImageView thumbnail;

        public MyViewHolder(View view) {
            super(view);
            title = (TextView) view.findViewById(R.id.title);
            count = (TextView) view.findViewById(R.id.count);
            thumbnail = (ImageView) view.findViewById(R.id.thumbnail);

            view.setOnClickListener(this);
        }

        @Override
        public void onClick(View view) {
            Log.d("myTag", "onClick " + getPosition());
        }
    }


    public cardsAdapter(Context mContext, List<CardModel> albumList) {
        this.mContext = mContext;
        this.albumList = albumList;
    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.card_layout, parent, false);

        return new MyViewHolder(itemView);
    }

    @Override
    public void onBindViewHolder(final MyViewHolder holder, int position) {
        CardModel album = albumList.get(position);
        holder.title.setText(album.getCountry());
        holder.count.setText(album.getSong());

        // loading album cover using Glide library
        Glide.with(mContext).load(album.getThumbnail()).into(holder.thumbnail);

        holder.thumbnail.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Log.d("myTag", "onClick ");

            }
        });

//        holder.overflow.setOnClickListener(new View.OnClickListener() {
//            @Override
//            public void onClick(View view) {
//                showPopupMenu(holder.overflow);
//            }
//        });
    }



//    /**
//     * Showing popup menu when tapping on 3 dots
//     */
//    private void showPopupMenu(View view) {
//        // inflate menu
//        PopupMenu popup = new PopupMenu(mContext, view);
//        MenuInflater inflater = popup.getMenuInflater();
//        popup.setOnMenuItemClickListener(new MyMenuItemClickListener());
//        popup.show();
//    }

//    /**
//     * Click listener for popup menu items
//     */
//    class MyMenuItemClickListener implements PopupMenu.OnMenuItemClickListener {
//
//        public MyMenuItemClickListener() {
//        }
//
//        @Override
//        public boolean onMenuItemClick(MenuItem menuItem) {
//            switch (menuItem.getItemId()) {
//                case R.id.action_add_favourite:
//                    Toast.makeText(mContext, "Add to favourite", Toast.LENGTH_SHORT).show();
//                    return true;
//                case R.id.action_play_next:
//                    Toast.makeText(mContext, "Play next", Toast.LENGTH_SHORT).show();
//                    return true;
//                default:
//            }
//            return false;
//        }
//    }

    @Override
    public int getItemCount() {
        return albumList.size();
    }
}

我能够使用您提供的Adapter来创建RecyclerView，其中的项目可以在缩略图和父项视图上点击。

查看您的XML card_layout，确保您的ImageView没有android:clickable到false。发布您的card_layout XML。

这是我使用的card_layout：

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <TextView
        android:id="@+id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginStart="8dp"
        android:text="Album"
        app:layout_constraintStart_toEndOf="@+id/thumbnail"
        app:layout_constraintTop_toTopOf="@+id/thumbnail"/>

    <TextView
        android:id="@+id/count"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginStart="8dp"
        android:layout_marginTop="8dp"
        android:text="Count"
        app:layout_constraintStart_toEndOf="@+id/thumbnail"
        app:layout_constraintTop_toBottomOf="@+id/title"/>

    <ImageView
        android:id="@+id/thumbnail"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="8dp"
        android:layout_marginStart="8dp"
        android:layout_marginTop="8dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:srcCompat="@mipmap/ic_launcher"/>

</android.support.constraint.ConstraintLayout>
