私のコードをPHPのようなこのhttp://prntscr.com/bkw700 成功= 0

http://prntscr.com/bkw796このような私のコードのアンドロイドのような成功は= 1誰でも私のプログラムを解決するのを助けることができますか？ おかげデータ

Answer 1

前に、productsListは、修正以下

protected void onPostExecute(String file_url) { 
    // dismiss the dialog after getting all products 
    pDialog.dismiss(); 
    if (productsList != null) { // <--- Add null check here 
     ListAdapter adapter = new SimpleAdapter(
      ListLogItemIGN.this, productsList, 
      R.layout.list_inputitem, new String[]{ 
      TAG_NAME, TAG_CODEITEM, TAG_UPGRADEITEM, TAG_DATEITEM}, 
      new int[]{ R.id.title, R.id.rating, R.id.genre, R.id.releaseYear}); 

     getListView().setAdapter(adapter); 
    } 

}
