Android 禁止横竖屏切换

想要Android应用只用竖屏，要在Manifest.xml文件设置属性（只能设置在Activity上）：

[html] view
plaincopy

android:screenOrientation="portrait" --> 只用竖屏

[html] view
plaincopy

android:configChanges="keyboardHidden|orientation" --> 如此设置当用户横竖屏时不会重启Activity

完整的例子：

[html] view
plaincopy

<application android:label="@string/app_name"

android:icon="@drawable/icon"

android:name=".MyApplication">

<activity android:theme="@style/Theme.Welcome"

android:label="@string/app_name"

android:name=".MainIndexActivity"

android:screenOrientation="portrait"

android:configChanges="keyboardHidden|orientation">

<intent-filter>

<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />

</intent-filter>

</activity>

</application>

portrait 竖屏

landscape 横屏
