以编程方式禁用/延迟Android锁定屏幕

Question

I'd like to disable/delay the lock screen programmatically. In looking into this, KeyguardManager is depreciated/doesn't work consistently, FLAG_DISMISS_KEYGUARD is not an option because I want to do this in the background, I don't want to use WakeLock for battery reasons, Device Administration does not appear to be capable of this and, while SCREEN_OFF_TIMEOUT is available to control when the screen sleeps, I was unable to find a similar timeout for the screen lock.

What am I missing here? Thanks.

Answer 1

try this, it will keep awake the screen/ display , as long as the activity is on top. getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

Also this does not require any permission in manifest.

Answer 2

@nandeesh的答案正在运行，但已弃用 ，禁用锁屏使用标志：

getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);

Answer 3

Did you try this?

KeyguardManager keyguardManager = (KeyguardManager)getSystemService(Activity.KEYGUARD_SERVICE);
KeyguardLock lock = keyguardManager.newKeyguardLock(KEYGUARD_SERVICE);
lock.disableKeyguard();

Add

<uses-permission android:name="android.permission.DISABLE_KEYGUARD"/>

You can disable the keyguard using this.
