如何在同一活動中處理多個對話框

Question

我正在創建一個應用程序，該活動需要超過3個對話框用於不同的目的。我正在使用onCreateDialog()方法，它目前正在處理一個在XML文件中定義的單個對話框，我需要知道的是如何在不使我的代碼大的情況下處理更多的xml文件。

@Override 
protected Dialog onCreateDialog(int id){ 

     return createExampleDialog(); // Function call, body is defined below 
} 

// This method is used for setting the dialogbox 
@Override 
protected void onPrepareDialog(int id,Dialog loginPrompt){ 
    final EditText first = (EditText)loginPrompt.findViewById(R.id.rf1); 
    first.setText(""); // setting the editbox blank 
    final EditText second = (EditText)loginPrompt.findViewById(R.id.rf2); 
    second.setText(""); 
} 

//Body the function createExampleDialog() 
private Dialog createExampleDialog(){ 
    LayoutInflater factory = LayoutInflater.from(this); 
    final View textEntryView = factory.inflate(R.layout.userpasslayout, null); 
    AlertDialog.Builder alert = new AlertDialog.Builder(this); 
    alert.setTitle("Add Location!"); 
    alert.setIcon(R.drawable.logo); 
    alert.setMessage("Fill information carefully!"); 
    alert.setView(textEntryView); 
    //AlertDialog loginPrompt = alert.create(); 

    //PositiveButton Onclick Listener 
    alert.setPositiveButton("Register", new DialogInterface.OnClickListener() { 
     @Override 
     public void onClick(DialogInterface dialog, int which) { 
      // TODO Auto-generated method stub 
      Toast.makeText(DialogActivity.this, "So you think!", Toast.LENGTH_LONG).show(); 
      return; 
     } 
    }); 

    //NegativeButton onclick Listener 
    alert.setNegativeButton("cancel", new DialogInterface.OnClickListener() {  
     @Override 
     public void onClick(DialogInterface dialog, int which) { 
      // TODO Auto-generated method stub 
      // NegtiveButton works automatic it will perform cancel of the dialog box; 

      return; 
     } 
    }); 
    return alert.create(); 
} 

}

使用

switch(id){ 
     case exampleDialog_id: 
      return showExapleDialog(); 
     break; 
     case secondDialog_id: 
      returnshowSecondDialog; 
     break; 
     default: 
     return null;}
