                android:textColor="@color/primary_dark_material_light" />
        </LinearLayout>
    </RelativeLayout>
    </LinearLayout>

</LinearLayout>

以下是onClick代码:

holder.setClickListener(new MyViewHolder.ClickListener() {
            @Override
            public void onClick(View v, int position, boolean isLongClick) {
                if(isLongClick)
                {
                    /* TASK TO PERFORM AT LONG CLICKS */
                    Toast.makeText(context, "Long click acheived", Toast.LENGTH_LONG).show();
                }
                else
                {
                    /* TASK TO PERFORM AT CLICKS */
                    Toast.makeText(context, "Click Event", Toast.LENGTH_LONG).show();
                }
            }
        });

现在，当我运行它时，一切正常，除了单击行项目不会产生任何响应(在本例中为 toast )

任何帮助将不胜感激。需要帮助!

MyViewHolder类中点击事件的处理方法如下:

static class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener,View.OnLongClickListener {

    //Following represent grid_layout item
    TextView txtFileName;
    TextView txtFileIssueTime;
    Button btnAnswer;
    private ClickListener clickListener;
    public MyViewHolder(View itemView) {
        super(itemView);

        //VIEWS IN LAYOUT BEING INITIALIZED

        btnAnswer = (Button) itemView.findViewById(R.id.btn_answer);
        itemView.setOnClickListener(this);
        itemView.setOnLongClickListener(this);
    }

    /* Interface for handling clicks - both normal and long ones. */
    public interface ClickListener {

        /**
         * Called when the view is clicked.
         *
         * @param v view that is clicked
         * @param position of the clicked item
         * @param isLongClick true if long click, false otherwise
         */
        public void onClick(View v, int position, boolean isLongClick);

    }

    /* Setter for listener. */
    public void setClickListener(ClickListener clickListener) {
        this.clickListener = clickListener;
    }

    @Override
    public void onClick(View v) {

        // If not long clicked, pass last variable as false.
        clickListener.onClick(v, getAdapterPosition(), false);
    }

    @Override
    public boolean onLongClick(View v) {

        // If long clicked, passed last variable as true.
        clickListener.onClick(v, getAdapterPosition(), true);
        return true;
    }

}

尝试将 clickable 移动到父 LinearLayout 中，而不是嵌套的 LinearLayout

编辑:

实际上，你的布局应该是

<FrameLayout
    android:background:"@color/white"
    android:foreground:"?selectableItemBackground">

    <RelativeLayout />

</FrameLayout>
