android SimpleAdapter 中添加按钮响应事件

 SimpleAdapter是适配器中扩展性最好的，但是如果用simpleAdapter添加按钮，为按钮添加响应事件很难做到。为此我们可以继承simpleAdapter，自己实现响应事件。

示例如下：

 

private class MySimpleAdapter extends SimpleAdapter {

		public MySimpleAdapter(Context context,
				List> data, int resource,
				String[] from, int[] to) {
			super(context, data, resource, from, to);
			// TODO Auto-generated constructor stub
		}

		@Override
		public View getView(int position, View convertView, ViewGroup parent) {
			// TODO Auto-generated method stub
			final int mPosition = position;
			convertView = super.getView(position, convertView, parent);
			Button buttonAdd = (Button) convertView
					.findViewById(R.id.button_add);// id为你自定义布局中按钮的id
			buttonAdd.setOnClickListener(new View.OnClickListener() {

				@Override
				public void onClick(View v) {
					// TODO Auto-generated method stub
					mHandler.obtainMessage(BUTTON_ADD, mPosition, 0)
							.sendToTarget();
				}
			});
			Button buttonDelete = (Button) convertView
					.findViewById(R.id.button_delete);
			buttonDelete.setOnClickListener(new View.OnClickListener() {

				@Override
				public void onClick(View v) {
					// TODO Auto-generated method stub
					mHandler.obtainMessage(BUTTON_DELETE, mPosition, 0)
							.sendToTarget();
				}
			});
			return convertView;
		}

		private Handler mHandler = new Handler() {

			@Override
			public void handleMessage(Message msg) {
				// TODO Auto-generated method stub
				super.handleMessage(msg);
				switch (msg.what) {
				case BUTTON_ADD:
					HashMap map = new HashMap();
					mList.add(map);
					notifyDataSetChanged();// 这个函数很重要，告诉Listview适配器数据发生了变化
					mShowInfo.setText("你点击了第" + (msg.arg1 + 1) + "按钮");
					break;
				case BUTTON_DELETE:
					mList.remove(msg.arg1);
					notifyDataSetChanged();
					mShowInfo.setText("你删除了第" + (msg.arg1 + 1) + "行");
					break;
				}
			}

		};

	}
