另一片自定义dialog点击打开链接
主页面布局--2个button（一个弹出alertDialog，一个是自定义dialog）
activity_main.xml

————————————————————关于Activity透明的样式——————————————————
<activity
android:name=".ui.gesture.GestureVerifyActivity"
android:label="@string/app_name"
android:screenOrientation="portrait"
android:theme="@style/Transparent" >
</activity>
<style name="Transparent">
<item name="android:windowBackground">@color/transparent</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowNoTitle">true</item>
</style>
<color name="transparent">#00000000</color>
或者直接设置背景即可
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="center_horizontal"
android:background="#7A000000" >
<activity
android:name=".ui.LandScapeActivity"
android:theme="@android:style/Theme.Translucent.NoTitleBar" >
<intent-filter>
<action android:name="com.godinsec.seland.landscape" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
