AlertDialog后的AlertDialog

我不断收到我的代码错误。我试图在AlertDialog中调用一个新的AlertDialog。它似乎有一个显示salert一个问题，但我不明白为什么...AlertDialog后的AlertDialog

public String passA = ""; 
public String passB = ""; 

public void createPassword() { 
    final AlertDialog.Builder alert = new AlertDialog.Builder(this); 
    final AlertDialog.Builder salert = new AlertDialog.Builder(this); 
    final EditText input = new EditText(this); 
    input.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD 
      | InputType.TYPE_CLASS_TEXT); 

    salert.setView(input); // edit text added to alert 
    alert.setView(input); // edit text added to alert 
    salert.setTitle("Widerholen Sie Ihre PIN"); // title setted 
    alert.setTitle("Geben Sie eine PIN an"); // title setted 

    final OnClickListener b = new OnClickListener() { 
     public void onClick(DialogInterface arg0, int arg1) { 
      passB = input.getText().toString(); 
      if (passA.equals(passB)) { 
       editor = settings.edit(); 
       editor.putString("password", passA); 
       editor.commit(); 
       logged_in = true; 
       return; 
      } 
     } 
    }; 
    salert.setPositiveButton("OK", b); 

    OnClickListener a = new OnClickListener() { 
     public void onClick(DialogInterface arg0, int arg1) { 
      passA = input.getText().toString(); 

      salert.show(); 
      return; 
     } 
    }; 

    alert.setPositiveButton("OK", a); 

    alert.setOnCancelListener(new OnCancelListener() { 

     public void onCancel(DialogInterface dialog) { 
      // TODO Auto-generated method stub 
      Functions.writeError("Falsche PIN Eingabe."); 
      finish(); 
     } 

    }); 
    alert.show(); 
}

我得到的错误是：

类似的问题：http://stackoverflow.com/questions/9167638/android-the-specified-child-already-has-a-父任您必须叩removeview-O –

您正在使用一个视图进行多个对话，一个视图只能有一个父对象。

变化：

final EditText input = new EditText(this); 

salert.setView(input); // edit text added to alert 
alert.setView(input); // edit text added to alert

要：

final EditText firstInput = new EditText(this); 
final EditText secondInput = new EditText(this); 

salert.setView(firstInput); // edit text added to alert 
alert.setView(secondInput); // edit text added to alert
