單擊imageswitcher時出現錯誤

單擊imageswitcher時，獲取logcat中顯示的錯誤classcastexception。請幫我傢伙代碼中，我感到當點擊imageswitcher單擊imageswitcher時出現錯誤

gallery.setOnItemClickListener(new OnItemClickListener() { 
      public void onItemClick(AdapterView<?> parent, View v, int position, long id) { 
       //List<String> it; 
        imageId = parent.getAdapter().getItemId(position); 
       try {} 
}

，我使用這個圖片ID

imageView.setLayoutParams(new ViewGroup.LayoutParams(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT)); 

     imageView.setImageResource((int) imageid); 
     imageView.setScaleType(ImageView.ScaleType.FIT_XY);

Eclipse的摸索中的另一個使用。只需清理一次您的項目，它會重建您的R.java文件。

更新1

我不明白你爲什麼要明確類型轉換imageid。只需使用int imageid= R.drawable.somepic

更新2

嘗試改變getItemId到getResourceId。

我已經做了清理和重建，但沒有改變 –

什麼是'imageid'？它是什麼類型？如果你正在訪問資源文件，然後檢查我的答案。 –

imageId = parent.getAdapter（）。getItemId（position）;當從圖庫中選擇圖片 –
