獲取微調選擇後Parse.com

Question

我試圖讓微調選擇已使用Parse.com

這是我所得到的，當我使用 uniSpinner.getSelectedItem().toString(); 充滿後動態加油吧這是我得到：

com.parse.ParseObject@"Some numbers here, not the ID stored in parse" 

下面的代碼也產生同樣的結果：

Toast.makeText(parent.getContext(), "test: " + 
      parent.getItemAtPosition(position).toString(), Toast.LENGTH_LONG).show(); 

這是我第代碼在創造微調：

public void uniSpinnerSetup() 
{ 
    ParseQueryAdapter.QueryFactory<ParseObject> factory = new ParseQueryAdapter.QueryFactory<ParseObject>() { 
     public ParseQuery create() { 
      ParseQuery query = new ParseQuery("University"); 
      return query; 
     } 
    }; 

    uniSpinner = (Spinner) findViewById(R.id.uniSpinner); 

    ParseQueryAdapter<ParseObject> adapter = new ParseQueryAdapter<ParseObject>(this, factory); 
    adapter.setTextKey("name"); 
    uniSpinner.setAdapter(adapter); 
    uniSpinner.setSelection(1); 
    uniSpinner.setOnItemSelectedListener(new mySpinnerListener()); 
} 

class mySpinnerListener implements Spinner.OnItemSelectedListener 
{ 
    @Override 
    public void onItemSelected(AdapterView parent, View v, int position,long id) { 
     // TODO Auto-generated method stub 
     Toast.makeText(parent.getContext(), "test: " + 
       parent.getItemAtPosition(position).toString(), Toast.LENGTH_LONG).show(); 

    } 

    @Override 
    public void onNothingSelected(AdapterView parent) { 
     // TODO Auto-generated method stub 
     // Do nothing. 
    } 

} 

我看上去很高和低嘗試和解決它，還沒有找到解決方案！請幫忙嗎？

（正確答案是在評論部分）

了移動適配器作爲一個字段變量，使用讓您的對象：

ParseQueryAdapter<ParseObject> adapter; 

public void uniSpinnerSetup() 
{ 
    ParseQueryAdapter.QueryFactory<ParseObject> factory = new ParseQueryAdapter.QueryFactory<ParseObject>() { 
     public ParseQuery create() { 
      ParseQuery query = new ParseQuery("University"); 
      return query; 
     } 
    }; 

    uniSpinner = (Spinner) findViewById(R.id.uniSpinner); 

    adapter = new ParseQueryAdapter<ParseObject>(this, factory); 
    adapter.setTextKey("name"); 
    uniSpinner.setAdapter(adapter); 
    uniSpinner.setSelection(1); 
    uniSpinner.setOnItemSelectedListener(new mySpinnerListener()); 
} 

class mySpinnerListener implements Spinner.OnItemSelectedListener 
{ 
    @Override 
    public void onItemSelected(AdapterView parent, View v, int position,long id) { 
     // TODO Auto-generated method stub 
     ParseObject theSelectedObject = adapter.getItem(position); 
     Toast.makeText(parent.getContext(), "test: " + 
       theSelectedObject.toString(), Toast.LENGTH_LONG).show(); 

    } 

    @Override 
    public void onNothingSelected(AdapterView parent) { 
     // TODO Auto-generated method stub 
     // Do nothing. 
    } 

}
