listview 弹窗效果实现 +类似qq的滑动删除效果
需求： 点击ListItem 后 在item上弹出一个类似PopupWindows 的东西里面的选项根据Item的不同可以或多或少。比如说歌曲列表，有的只有下载和收藏。但有的还有mv等其他选项。昨天参考了gitHub上的一个例子。
可今天才发现它一旦写好就每个item弹出项就是固定的了。不能动态增加选项。就比如说，所有的歌曲都是下载和收藏不能再进行其他操作了。
移到getView 中是这样的（比较乱，有些代码是用来实现listview滑动删除的）

经过一晚上的测试楼主最后总算是可以动态更改了。根本方法就是把以前写在OnCreate的如下代码全部放到了listview Adapter的getView 里面实现。
之前是这么写的（已经注释掉了）
public class MainActivity extends Activity
{
private int mSelectedRow = 0;
private MyAdapter myAdapter;
private ListView listview;
public ImageView mMoreIv = null;
CursorLoader loader=null;
public QuickAction mQuickAction =null;

return mQuickAction;
}

this.mQuickAction = mQuickAction;
}

actionBar = (ActionBar) findViewById(R.id.actionbar);
actionBar .setTitle("首页");
// actionBar.setHomeAction(new IntentAction(this, createIntent(this), R.drawable.ic_title_home_demo));
//使用loagermanager
//这个以后写到收藏activity里
