* 设置ListView的适配器 有两种方式加载含CheckedTextView的多选模式并响应事件 1. 但是这种方式，选择多选响应事件时
* 各个Item会出现乱弹的现象，不知道为什么 希望各位大虾帮帮忙 //适配器设置 setListAdapter(new
* SimpleAdapter(this, arrlist, R.layout.list_checktextview, new
* String[]{"title"}, new int[]{R.id.checktv_title})); //listview的监听事件
* listView.setOnItemClickListener(new OnItemClickListener() {
*
* @Override public void onItemClick(AdapterView<?> parent, View view,
* int position, long id) { checktv = (CheckedTextView)
* parent.getChildAt(position).findViewById(R.id.checktv_title);
* if(checktv.isChecked()){ checktv.setChecked(false); }else{
* checktv.setChecked(true); } } }); 2. 通过自定义Adapter实现 如下，
