Android 项目需求:已经整好的列表ListView无侵入的加入右滑删除控件(自定义右滑控件操作)

已经整好了listView,后续需要加入右滑删除,在网上查了一堆资料,最终整理了一个无侵入性的

1.建立SwipeItemLayout  (作为子项item的最外层布局)

3.把原来item的布局最外层替换成新加入的SwipeItemLayout

// 略略略略略略略略略略略略略略
//这里是新加入的右滑出的自定义的布局 demo只写了一个删除按钮 

4.把原来的listView改成SwipeListView

 //支持在SmartRefreshLayout里 原来的功能不变
//只是把这的listView换了SwipeListView

5.原来listview的adapter不变 只需加入自定义控件的事件就好了

     RelativeLayout linearLayout = (RelativeLayout) holder.findViewById(R.id.ll_driver);linearLayout.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {//原来的item点击事件}}});Button btnDelete = (Button) holder.findViewById(R.id.btn_delete);btnDelete.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {//自定义的删除事件delete(driverId);mAdapter.notifyDataSetInvalidated();}});
