1、Android屏幕常亮/点亮
复制代码 代码如下:
//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();

复制代码 代码如下:
//释放屏幕常亮锁
if(null != mWakeLock) {
    mWakeLock.release();
}

2、Android屏幕解锁和锁定
复制代码 代码如下:
//屏幕解锁
KeyguardManager keyguardManager = (KeyguardManager)getSystemService(KEYGUARD_SERVICE);
KeyguardLock keyguardLock = keyguardManager.newKeyguardLock(LOCK_TAG);
keyguardLock.disableKeyguard();
//屏幕锁定
keyguardLock.reenableKeyguard();

3、相关权限
