如果KeyGuard未設置，如何檢測屏幕是否被鎖定 - Android？

Question

我想知道屏幕是否鎖定，當用戶沒有設置KeyGuard時廣播SCREEN_OFF？

Answer 1

1.Take的KeyguardManager文檔here

2.Try這個代碼

public class ScreenReceiver extends BroadcastReceiver { 

    @Override 
    public void onReceive(Context context, Intent intent) { 
     if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) { 
      // do whatever you need to do here 
      //screen is locked & check Keyguard is enabled or Not. 
      KeyguardManager keyguardManager = (KeyguardManager)getSystemService(Activity.KEYGUARD_SERVICE); 

      Log.v(TAG,""+keyguardManager.inKeyguardRestrictedInputMode()); 

     } else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) { 
      // and do whatever you need to do here 


     } 
    } 

} 

希望這有助於看看。

編碼快樂:)
