这里本来是想在右下角显示一个小三角形的，不知道为啥不显示，给它单独拿出来设置宽度和高度就显示。希望有知道的给我解惑一下。大家知识共享。

popupwindow.xml

<?xml version="1.0" encoding="utf-8"?>
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:background="@drawable/popupwindow_bg">
 
 <listview
  android:id="@+id/lsvmore"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"/>
</linearlayout>

这是最终的效果。
