自定义dialog的样式并比较日期

<style name="myDialogTheme" parent="android:style/Theme.Dialog">
<item name="android:windowNoTitle">true</item>
</style>

1、布局main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/hello" />
    <Button 
        android:id="@+id/btn"
        android:layout_height="wrap_content"
        android:layout_width="fill_parent"
        android:text="按下按钮试试"/>
