项目中遇到一个popupwindow的二级联动菜单，就花了时间搞了一下。先看一下实现效果。我用真机测试，就简单拍了一张。

Demo结构：

一.布局文件

1.activity.xml

[html] view plain copy

print ?

<RelativeLayout xmlns:android=“http://schemas.android.com/apk/res/android”
xmlns:tools=“http://schemas.android.com/tools”
android:layout_width=“match_parent”
android:layout_height=“match_parent” >
<Button
android:id=“@+id/btn1”
android:layout_width=“wrap_content”
android:layout_height=“wrap_content”
android:text=“显示popupwindow” />
</RelativeLayout>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <Button
        android:id="@+id/btn1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="显示popupwindow" />

</RelativeLayout>
