Question

我有一个应用程序，它应该在屏幕出现时解锁。

我尝试了一些东西，在.java文件和AndroidManifest中编写了一些代码，但它无法解锁设备。

这是我的代码;

Uri ringtone = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE);
    r = RingtoneManager.getRingtone(getApplicationContext(), ringtone);
    r.play();   

    /*
    PowerManager pm = (PowerManager) getApplicationContext().getSystemService(Context.POWER_SERVICE);
    WakeLock wakeLock = pm.newWakeLock((PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP), "TAG");
    wakeLock.acquire();


    KeyguardManager keyguardManager = (KeyguardManager) getApplicationContext().getSystemService(Context.KEYGUARD_SERVICE); 
    KeyguardLock keyguardLock =  keyguardManager.newKeyguardLock("TAG");
    keyguardLock.disableKeyguard(); 


    window = getWindow();
    window.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
    window.addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
    window.addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
    window.addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

    */

    PowerManager pm = (PowerManager) getApplicationContext().getSystemService(Context.POWER_SERVICE);
    WakeLock mWakeLock = pm.newWakeLock((PowerManager.PARTIAL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP), "MyService");
    mWakeLock.acquire();
    mWakeLock.release();

    Window window = getWindow();
    window.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);

此代码有什么问题？

你能帮我吗？

我已经尝试了你提供的所有答案，但仍然没有成功

您需要3个标记，FLAG_DISMISS_KEYGUARD，FLAG_SHOW_WHEN_LOCKED和FLAG_TURN_SCREEN_ON

import android.view.WindowManager.LayoutParams;
private Window window;

将此添加到您的onCreate()

中

    window = this.getWindow();
    window.addFlags(LayoutParams.FLAG_DISMISS_KEYGUARD);
    window.addFlags(LayoutParams.FLAG_SHOW_WHEN_LOCKED);
    window.addFlags(LayoutParams.FLAG_TURN_SCREEN_ON);

或使用onResume()方法，它适用于我=）

protected void onResume() {
    super.onResume();
    window = this.getWindow();
    window.addFlags(LayoutParams.FLAG_DISMISS_KEYGUARD);
    window.addFlags(LayoutParams.FLAG_SHOW_WHEN_LOCKED);
    window.addFlags(LayoutParams.FLAG_TURN_SCREEN_ON);
}
