Android点亮屏幕或屏幕解锁和锁定以及其他相关权限实现代码

//保持屏幕常亮
PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
mWakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, LOCK_TAG);
mWakeLock.acquire();

//释放屏幕常亮锁
if(null != mWakeLock) {
    mWakeLock.release();
}

//屏幕解锁
KeyguardManager keyguardManager = (KeyguardManager)getSystemService(KEYGUARD_SERVICE);
KeyguardLock keyguardLock = keyguardManager.newKeyguardLock(LOCK_TAG);
keyguardLock.disableKeyguard();
//屏幕锁定
keyguardLock.reenableKeyguard();
