AndroidManifest.xml
文件:
1.增加权限android.permission.CHANGE_CONFIGURATION
2.设置Activity的android:configChanges
属性
<uses-permission android:name="android.permission.CHANGE_CONFIGURATION" /><application> <activity android:name=".MainActivity" android:configChanges="orientation|screenSize" android:screenOrientation="portrait"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> intent-filter> activity>application>
android:screenOrientation="portrait"
禁止横竖屏切换
重写Activity中的onConfigurationChanged
方法。
* If any configuration change occurs that is not selected to be reported * by that attribute, then instead of reporting it the system will stop * and restart the activity (to have it launched with the new * configuration). @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); Logger.d("onConfigurationChanged=====" + newConfig.toString()); }
如果设置android:configChanges="orientation|screenSize"
,手机屏幕旋转会执行onConfigurationChanged()
方法,否则会重启当前activity。
