在ListFragment的单个元素被窃取投入甚至与的布局从的ImageButton 生成的问题，可聚焦元素设置为false，所以我不得不从布局中删除它。

我已经得到了通过扩展类SimpleCursorAdapter的填充一个ListFragment（主要用于覆盖NewView的方法），但我想补充一个AlertDialog当用户presses（或长presses）中的一个项目列出所产生的适配器。
我trye​​d既 onListItemClick 和 onItemLongClick 用一个简单的日志写 Log.d 方法，但什么也没有发生在这两种情况下，我不知道哪里是自code中的问题是非常简单的：

 公共类FragmentD扩展ListFragment {私人SQLiteDatabase分贝;@覆盖
公共无效onActivityCreated（捆绑savedInstanceState）{    super.onActivityCreated（savedInstanceState）;    MYDATABASE myDBHelper =新MYDATABASE（getActivity（））;
    DB = myDBHelper.getWritableDatabase（）;    Log.d（DB，插入fatto）;    的String [] = res_columns新的String [] {m​​yDatabase.COLUMN2，myDatabase.COLUMN2，};
    字符串中将sortOrder = myDatabase.COLUMN1 +DESC;    字符串，其中=*;    光标testCursor = db.rawQuery（选择*+ database.DATABASE_TABLE，NULL）;    myAdapter适配器=新myAdapter（getActivity（）
            R.layout.list_element，
            testCursor，
            res_columns，
            新的INT [] {}，
            0）;    setListAdapter（适配器）;
}@覆盖
公共无效onListItemClick（ListView中升，视图V，诠释POS，长I​​D）{
    super.onListItemClick（L，V，POS机，ID）;
        Log.d（点击，pressed）;
    }
 

解决方案

编辑答案：
    也许布局的成分从布局的其它部件窃取输入

SOLVED IN A COMMENT: Adding onListItemLick/onItemLongClick in a ListFragment The problem was generated from an ImageButton in the layout of the single element in the ListFragment that was stealing the input even with the focusable element set to false, so i had to remove it from the layout.

I've got a ListFragment populated by an extended class of SimpleCursorAdapter (mainly for overriding the newView method) but I wanted to add an AlertDialog when the user presses (or long presses) an item in the list the adapter generated. I've tryed both onListItemClick and onItemLongClick with a simple log write using Log.d method but nothing happens in both cases and i don't know where is the problem since the code is really simple:

public class FragmentD extends ListFragment {

private SQLiteDatabase db;

@Override
public void onActivityCreated (Bundle savedInstanceState) {

    super.onActivityCreated(savedInstanceState);

    myDatabase myDBHelper = new myDatabase(getActivity());
    db = myDBHelper.getWritableDatabase();

    Log.d("DB", "Insert fatto");

    String[] res_columns = new String[] {myDatabase.COLUMN2, myDatabase.COLUMN2,};
    String sortOrder = myDatabase.COLUMN1 + " DESC";

    String where = "*";

    Cursor testCursor = db.rawQuery("select * from " + database.DATABASE_TABLE, null);

    myAdapter adapter = new myAdapter(getActivity(),
            R.layout.list_element,
            testCursor,
            res_columns,
            new int[] { },
            0);

    setListAdapter(adapter);
}

@Override
public void onListItemClick (ListView l, View v, int pos, long id) {
    super.onListItemClick(l, v, pos, id);
        Log.d("CLICK", "pressed");
    }

解决方案

Edited Answer: Maybe the components of the layout were stealing the input from other components of the layout
