Alertdialog Benutzerdefinierte Layout-Ansichten nicht zugänglich android

Question

Ich habe eine Methode, die für AlertDialog zeigen und es hat ein eigenes Layout, die ein EditText enthält und OnPositive klicken Ich versuche, den Wert Bearbeiten von Text zu erhalten, aber die EditText.getText() immer leer zurück.

Code:

private void showForgetPassDialog() { 

     final View view = getLayoutInflater().inflate(R.layout.alert_dialog_forgot_pass, null); 

     AlertDialog.Builder builder = new AlertDialog.Builder(LoginActivity.this); 
     builder.setCancelable(false); 
     builder.setTitle(getString(R.string.forgot_password)); 
     builder.setMessage(getString(R.string.reset_pass)); 
     final EditText emailTxt = (EditText) view.findViewById(R.id.email_field); 
     emailReset = emailTxt.getText().toString(); 
     String positiveText = getString(R.string.submit); 
     builder.setPositiveButton(positiveText, 
       new DialogInterface.OnClickListener() { 
        @Override 
        public void onClick(DialogInterface dialog, int which) { 
         Toast.makeText(LoginActivity.this, "test :"+emailReset, Toast.LENGTH_SHORT).show(); 
         if(!emailReset.equals("") && isValidEmail(emailReset)){ 
          resetPassword(emailReset); 
         }else{ 
          emailTxt.setError(getString(R.string.error_email)); 
         } 

        } 
       }); 

     String negativeText = getString(R.string.cancel); 
     builder.setNegativeButton(negativeText, 
       new DialogInterface.OnClickListener() { 
        @Override 
        public void onClick(DialogInterface dialog, int which) { 
         dialog.dismiss(); 
        } 
       }); 

     final AlertDialog dialog = builder.create(); 
     dialog.setOnShowListener(new DialogInterface.OnShowListener() { 
      @Override 
      public void onShow(DialogInterface dialogInterface) { 
       dialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(ContextCompat.getColor(LoginActivity.this,R.color.colorAccentDark)); 
       dialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(ContextCompat.getColor(LoginActivity.this,R.color.PrimaryBlue)); 

      } 
     }); 
     dialog.setView(view); 
     // display dialog 
     dialog.show(); 
    }

    android:layout_marginStart="10dp" 
    android:layout_marginRight="10dp" 
    android:layout_marginEnd="10dp" 
    > 
    <EditText 
     android:textCursorDrawable="@null" 
     android:id="@+id/email_field" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_centerInParent="true" 
     android:ellipsize="start" 
     android:gravity="center_horizontal" 
     android:hint="@string/email_label" 
     android:inputType="textEmailAddress" 
     android:textColor="#484848" /> 

    <View 
     android:id="@+id/login_bar"
