java - tablayout 中 cardview 的 onClickListener 不起作用

Question

我在 tablayout 中的 recyclerview 中有一个 cardview。我在适配器的卡片 View 上放置了一个 onClickListener，但它不起作用。我只想在点击卡片时启动 EquationsActivity。在使用卡片的 Listener 界面之前，我已经让这个工作了。但这不起作用，唯一的区别是在这种情况下，我的 recyclerview 在 tablayout 中。我不确定这是否会导致任何问题。

感谢您的任何建议!

我的 recyclerViewAdapter:

public class recylcerAdapter extends RecyclerView.Adapter<recylcerAdapter.ViewHolder> {
    private ListView listView;
    private String title;
    private Cursor cursor;
    private Context context;
    private TextView textView;
    private ImageView imageView;
    private int[] imageIds;
    private String[] nameArray;




    public static class ViewHolder extends RecyclerView.ViewHolder{
        //define the viewholder and store card views
        //constructor

        private TextView textView;
        private ImageView imageView;

        private CardView cardView;

        public ViewHolder(CardView v){
            super(v);
            cardView = v;

        }
    }


    public recylcerAdapter(Context context, String title, Cursor cursor, int[]imageIds, String[]nameArray){
        this.cursor = cursor;
        this.title = title;
        this.context = context;

        this.imageIds = imageIds;
        this.nameArray = nameArray;
    }


    @Override
    public  recylcerAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType){
        //create a new view
        CardView cardView = (CardView) LayoutInflater.from(parent.getContext()).inflate(R.layout.cardview_main, parent, false);
        return new ViewHolder(cardView);

    }

    public void onBindViewHolder(ViewHolder holder, final int position){
        //set the values inside the given view

        CardView cardView = holder.cardView;
        ImageView imageView = (ImageView) cardView.findViewById(R.id.list_icon);
        Drawable drawable = cardView.getResources().getDrawable(imageIds[position]);
        imageView.setImageDrawable(drawable);
        imageView.setContentDescription(nameArray[position]);
        TextView textView = (TextView) cardView.findViewById(R.id.card_text);
        textView.setText(nameArray[position]);

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

                Toast toast = Toast.makeText(context, "worked", Toast.LENGTH_SHORT);
                toast.show();
                    Intent intent = new Intent(context, EquationsActivity.class);
context.startActivity(intent);



            }
        });



    }

    @Override
    public int getItemCount(){
        //return number of items in the data set
        return nameArray.length;
    }
}

尝试从 ViewPager 中删除 android:clickable="true"，并将其添加到您希望可点击的卡片的 xml 中。
