android.view.WindowLeaked: Fehler beim Anzeigen des Alarmdialogs mit

Question

Ich habe versucht, den Alarmdialog zu schließen, wenn die Aktivität zerstört wird.

@Override 
    public void onDestroy(){ 
     super.onDestroy(); 
     if (alertDialog != null && alertDialog.isShowing()) { 
      alertDialog.dismiss(); 
     } 
    } 

Aber ich habe immer noch einen Fehler:

android.view.WindowLeaked: Activity com.Forewarn.ForewarnApp.activities.SignInActivity has leaked window DecorView@60f300f[] that was originally added here

hier ist meine Tätigkeit:

if(AccountUtils.getIsTouch().equalsIgnoreCase("true")){ 
    checkTouchId.setChecked(true); 
    checkTouchId.setVisibility(View.GONE); 
    txtTouchId.setVisibility(View.VISIBLE); 
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { 
     //Fingerprint API only available on from Android 6.0 (M) 
     keyguardManager = (KeyguardManager) getSystemService(KEYGUARD_SERVICE); 
     fingerprintManager = (FingerprintManager) getSystemService(FINGERPRINT_SERVICE); 
     getFingerPrint(); 
    } else { 
     Toast.makeText(getApplicationContext(),"Your Device does not have a Fingerprint Sensor",Toast.LENGTH_SHORT).show(); 
    } 
} else { 
    getFingerPrintHardware(); 
} 

ich Fehler in folgenden Verfahren erhalten: in diesem Ich bin mit zwei Alarm Dialoge.

public void getFingerPrint(){ 
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { 
     if(!fingerprintManager.isHardwareDetected()){

          alertDialogBuilder.setIcon(R.drawable.fingerprint);

          alertDialog.show(); 

          generateKey(); 

          if (cipherInit()) { 
           FingerprintManager.CryptoObject cryptoObject = new FingerprintManager.CryptoObject(cipher); 
           FingerprintHandler helper = new FingerprintHandler(this); 
           helper.startAuth(fingerprintManager, cryptoObject); 
          } 
         } 
        } 
       } 
      } 
     } 
    } 
} 

Ich habe bereits onDestroy Methode, die dailog.dismiss() ruft. Ich bin verwirrt, um herauszufinden, wo ich falsch gemacht habe. Bitte hilf mir.

Answer 1

leaked window DecorView@60f300f[] that was originally added

• Über Ausnahmen kommen, wenn Dialoge sind nicht dismiss() vor Activity beendet.

Fügen Sie diesen Abschnitt onPause hinzu.

@Override 
    public void onPause(){ 
     super.onPause(); 
     if (alertDialog != null && alertDialog.isShowing()) { 
      alertDialog.dismiss(); 
     } 
    } 

Rectify

if (cipherInit()) { 
          FingerprintManager.CryptoObject cryptoObject = new FingerprintManager.CryptoObject(cipher); 
          FingerprintHandler helper = new FingerprintHandler(this); 
          helper.startAuth(fingerprintManager, cryptoObject); 
         } 
          generateKey(); 
          alertDialog = alertDialogBuilder.create(); 
          alertDialog.show(); 

Answer 2

Im Allgemeinen dieses Problem tritt auf, wenn Sie versuchen, den Dialog zu zeigen, nachdem Ihre Aktivität zerstört wird, fertig, onPause, ...

Einige Lösungen:

• Überprüfen Sie, ob Sie nicht ca Füllen Sie die alertDialog.show(); im selben übergeordneten Bereich, in dem Sie fertig sind, pausieren oder zerstören Sie Ihre Aktivität und versuchen Sie, sie zu kontrollieren.

  for example, you've started another activity or process and then you try to show your dialog on the current activity

• können Sie überprüfen, ob die Aktivität vor dem Aufruf des Dialog if(!this.isFinishing()){//show your dialog}this für yourActivity beendet ist

• Sie können auch einen kleinen Trick den Zustand Ihrer Aktivität zu überprüfen, bevor ein Dialog zu starten. :

  @Override protected void onPause() { isRunning = false; }

  @Override protected void onResume() { isRunning = true; }
