android学习之-ListView实现特殊效果

1. ListView

  list = new ArrayList<String>();  list.add("搜索");  list.add("主题设定");  list.add("发送队列");  list.add("我的资料");  list.add("设置");  list.add("意见反馈");  list.add("退出当前账号");    listView = (ListView)this.findViewById(R.id.activity_test_more_listview);  MoreActivityAdapter adapter = new MoreActivityAdapter(TestMoreActivity.this,list);  listView.setAdapter(adapter);    listView.setOnItemClickListener(new OnItemClickListener() {}

2.MoreActivityAdapter
