<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">

</shape>

使用：

new CommonDialog(getActivity(), R.style.MyDialog, new CommonDialog.OnCloseListener() {
@Override
public void onClick(Dialog dialog, boolean confirm) {
//To do what you want
}
}).setTitle(" 我是标题").setContent("我是内容").show();

可以设置标题，内容，按钮文字，一个按钮或两个按钮，这些都可以通过链式方式设置。
