1，圆角对话框的背景布局文件XML。
--------rounded_corners_pop.xml此为PopupWindow的背景布局文件
<?xml version="1.0" encoding="utf-8"?><shape xmlns:android="http://schemas.android.com/apk/res/android"><solid android:color="#ffffffff" /><stroke android:width="3dp" color="#ffff8080" /><corners android:radius="10dp" /><padding android:left="3dp" android:top="3dp" android:right="3dp" android:bottom="3dp" /></shape>?
--------rounded_corners_view.xml此为对话框内容的背景布局文件
<?xml version="1.0" encoding="utf-8"?><shape xmlns:android="http://schemas.android.com/apk/res/android"><solid android:color="#ff606060" /><stroke android:width="3dp" color="#ffff8080" /><corners android:radius="10dp" /><padding android:left="5dp" android:top="5dp" android:right="5dp" android:bottom="5dp" /></shape>?
?2，圆角文字编辑框的三个布局XML文件
