Android 禁止锁屏与禁止系统自动旋转屏幕

一. 应用程序界面禁止锁屏

KeyguardManager mKeyguardManager = (KeyguardManager) context.getSystemService(Context.KEYGUARD_SERVICE);
KeyguardLock mKeyguardLock = mKeyguardManager.newKeyguardLock("");//初始化键盘锁，可以锁定或解开键盘锁
mKeyguardLock.disableKeyguard();//禁用显示键盘锁定

<uses-permission android:name="android.permission.DISABLE_KEYGUARD" /><!-- 解锁的权限 -->

frameworks\base\packages\SettingsProvider\res\values\defaults.xml

<bool name="def_lockscreen_disabled">true</bool>
