【问题描述】：

我将simpleItemTouchCallback 附加到recyclerView 用于滑动列表中的项目。

              @Override
              public void onChildDraw(Canvas c, RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, float dX, float dY, int actionState, boolean isCurrentlyActive) {
                    if (actionState == ItemTouchHelper.ACTION_STATE_SWIPE) {
                        View itemView = viewHolder.itemView;
                        float height = (float) itemView.getBottom() - (float) itemView.getTop();
                        float width = height / 3;
                        if (dX / 3 > 0) {
                            RectF rect = new RectF((float) itemView.getLeft(), (float) itemView.getTop(), dX / 3, (float) itemView.getBottom());
                            LayoutInflater li = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                            View v = li.inflate(R.layout.complete_layout, null);
                            v.measure(View.MeasureSpec.getSize(v.getMeasuredWidth()), View.MeasureSpec.getSize(v.getMeasuredHeight()));
                            v.layout(0, 0, Math.round(rect.width()), Math.round(rect.height()));
                            c.save();
                            c.translate(rect.left, rect.top);
                            v.draw(c);
                        } else {
                            RectF rect1 = new RectF((float) itemView.getRight() + dX / 3, (float) itemView.getTop(), (float) itemView.getRight(), (float) itemView.getBottom());
                            LayoutInflater li1 = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                            View v = li1.inflate(R.layout.delete_layout, null);
                            v.measure(View.MeasureSpec.getSize(v.getMeasuredWidth()), View.MeasureSpec.getSize(v.getMeasuredHeight()));
                            v.layout(0, 0, Math.round(rect1.width()), Math.round(rect1.height()));
                            c.save();
                            c.translate(rect1.left, rect1.top);
                            v.draw(c);
                        }
                        c.restore();
                    }
 super.onChildDraw(c, recyclerView, viewHolder, dX / 3, dY, actionState, isCurrentlyActive);

滑动和绘制新布局正常工作。现在想在新布局中添加一个OnClickListener。我找不到这样做的方法。

【解决方案1】：

这应该工作。但在我的代码中，视图根本不可点击。也许它对你有用。

RectF rect1 = new RectF((float) itemView.getRight() + dX / 3, (float) itemView.getTop(), (float) itemView.getRight(), (float) itemView.getBottom());
LayoutInflater li1 = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = li1.inflate(R.layout.delete_layout, null);
v.measure(View.MeasureSpec.getSize(v.getMeasuredWidth()), View.MeasureSpec.getSize(v.getMeasuredHeight()));
v.layout(0, 0, Math.round(rect1.width()), Math.round(rect1.height()));
c.save();
c.translate(rect1.left, rect1.top); 

v.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    // implement here your code for the click
                }
});

【解决方案2】：

recyclerView.addOnItemTouchListener(
    new RecyclerItemClickListener(this, new RecyclerItemClickListener.OnItemClickListener() {
    @Override
    public void onItemClick(View view, int position) {
       //Magic happens here
    }
}

顺便说一句：我不知道你在你发布的方法中做了什么^^
