Question

我想通过编程解锁我的Android手机。我在Android 6.0下面使用了以下代码，但它有一些问题

    KeyguardManager km = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);
    final KeyguardManager.KeyguardLock kl = km .newKeyguardLock("MyKeyguardLock");
    kl.disableKeyguard();

    PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
    PowerManager.WakeLock wakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK
            | PowerManager.ACQUIRE_CAUSES_WAKEUP
            | PowerManager.ON_AFTER_RELEASE, "MyWakeLock");
    wakeLock.acquire();

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

因为不推荐使用KeyguardLock，所以我使用下面的代码

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

但它有错误

android.view.ViewRootImpl$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.

如何解决？其次，如果我的手机被密码锁定，我该如何解锁？谢谢

权限问题，您可以添加权限并授予此权限，因为棉花糖需要授予权限，您的代码在棉花糖完美之前正常工作。
