微調與點擊監聽器

我正在使用微調，當我試圖提取所選微調項目的項目ID時顯示錯誤。我的代碼在這裏：微調與點擊監聽器

public void dispspi() 
    { 
    spinner = (Spinner) findViewById(R.id.spinner1); 
    ArrayAdapter <String> adap= new ArrayAdapter(this, android.R.layout.simple_spinner_item, level); 

     spinner.setAdapter(adap); 
     spinner.setOnItemClickListener(new OnItemClickListener() { 

     public void onItemSelected(AdapterView<?> arg0, View arg1,int arg2, long arg3) 
     { 
      int item = spinner.getSelectedItemPosition(); 

      p=item; 
     } 


     @Override 
     public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, 
       long arg3) { 
      // TODO Auto-generated method stub 

     } 



    }); 
    }

如何獲取微調器的項目ID？任何幫助是提前

IIRC，你應該使用選定的監聽器，而不是點擊：

spinner.setOnItemSelectedListener(new OnItemSelectedListener()

然後你可以重寫代碼添加到您選擇的方法。

appreciated..Thanks你應該在聽者（OnItemSelectedListener）

public void onNothingSelected(AdapterView<?> arg0) { 
}

有這樣它可能沒有工作，但把它要一致但可能有其他錯誤還，你能提供錯誤日誌嗎？

private String selecteditem; 

spinner.setOnItemSelectedListener(new OnItemSelectedListener() 
{  
@Override 
public void onItemSelected(AdapterView adapter, View v, int i, long lng) { 

    selecteditem = adapter.getItemAtPosition(i).toString(); 
    //or this can be also right: selecteditem = level[i]; 
} 
    @Override  
    public void onNothingSelected(AdapterView<?> parentView) 
{   

} 
    });

spinner3.setOnItemSelectedListener(new OnItemSelectedListener() { 

     @Override 
     public void onItemSelected(AdapterView<?> parent, View v, 
       int postion, long arg3) { 
      // TODO Auto-generated method stub 
     String SpinerValue3 = parent.getItemAtPosition(postion).toString(); 

      Toast.makeText(getBaseContext(), 
        "You have selected 222 : " + SpinerValue3, 
        Toast.LENGTH_SHORT).show(); 

     } 

     @Override 
     public void onNothingSelected(AdapterView<?> arg0) { 
      // TODO Auto-generated method stub 

     } 
    });
