你也缺少** show（）**方法在這一行'Toast.makeText（ListMovingNames.this，position，Toast.LENGTH_SHORT）;' – Lucifer

你是對的我的不好，但是這並沒有解決問題 – philip

你能提供一個日誌嗎？ – NyanLH

Toast.makeText(ListMovingNames.this, position, Toast.LENGTH_SHORT);

第二個參數是資源ID。

Toast.makeText(ListMovingNames.this, String.valueOf(position), Toast.LENGTH_SHORT);

用這個方法替換掉了。

謝謝先生。你給出了正確的答案。 :)我還有一個問題，但我如何顯示您選擇的列表的內容，而不是位置呢？ – philip

從來沒有解決它我自己我只是使用此代碼 '產品=（（TextView）視圖）.getText（）。toString（）; temp.setText（product）;' – philip

public void onItemClick（AdapterView arg0，View view，int position， long id） –
