android 去標題和狀態和下面黑線

在values/styles.xml中加入下面內容

<resources xmlns:android="http://schemas.android.com/apk/res/android">    <!--        Base application theme, dependent on API level. This theme is replaced        by AppBaseTheme from res/values-vXX/styles.xml on newer devices.    -->    <style name="AppBaseTheme" parent="android:Theme.Light">        <!--            Theme customizations available in newer API levels can go in            res/values-vXX/styles.xml, while customizations related to            backward-compatibility can go here.        -->    </style>    <!-- Application theme. -->    <style name="AppTheme" parent="AppBaseTheme">        <!-- All customizations that are NOT specific to a particular API-level can go here. -->        <item name="android:windowNoTitle">true</item>        <item name="android:windowContentOverlay">@null</item>         <item name="android:windowFullscreen">?android:windowNoTitle</item>    </style></resources>

接下來在AndroidManifest.xml中修改，注意名字【註：name="AppTheme",  android:theme="&style/AppTheme"】

 <application        android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >

把上面的工作做完，就OK了。趕快去試試吧。
