Spinner：当所选项目保持不变时，不会调用 onItemSelected

我有一个OnItemSelectedListener for my Spinner，但当所选项目与前一项相同时，不会调用它。显然是OnClickListener不是一个选项Spinner。 我需要捕捉用户每次点击某个项目的时间。任何想法？

也许事实是这Spinner是在里面ActionBar扰乱正常行为？

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.tracklist_menu, menu);
    Spinner spinner = (Spinner) menu.findItem(R.id.option_ordering_spinner)
            .getActionView();
    spinner.setAdapter(mSpinnerAdapter);
    spinner.setSelection(PrefsHelper.getOrderingSpinnerPos(prefs));
    spinner.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> parent, View view,
                int position, long id) {
            String str = "selected";
            System.out.println(str);
            if (optionMenuInitialized) {

                switch (position) {
                case 0:
                    // rdm
                    getActivity()
                            .sendBroadcast(
                                    new Intent(
                                            MyIntentAction.DO_RESHUFFLE_PLAYLIST));
                    smp.setCurrentTracklistCursorPos(-1);
                    trackAdapter.notifyDataSetChanged();
                    break;
                case 1:
                    // artist
                    getActivity()
                            .sendBroadcast(
                                    new Intent(
                                            MyIntentAction.DO_ORDER_PLAYLIST_BY_ARTIST));
                    smp.setCurrentTracklistCursorPos(-1);
                    trackAdapter.notifyDataSetChanged();
                    break;
                case 2:
                    // folder
                    getActivity()
                            .sendBroadcast(
                                    new Intent(
                                            MyIntentAction.DO_ORDER_PLAYLIST_BY_FOLDER));
                    smp.setCurrentTracklistCursorPos(-1);
                    trackAdapter.notifyDataSetChanged();
                    break;
                }
                PrefsHelper.setOrderingSpinnerPos(prefEditor, position);
                prefEditor.commit();
            }
            optionMenuInitialized = true;
        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {
        }
    });
}

好吧，我终于找到了一个解决方案，通过创建我自己的类来扩展 Spinner ：

public class MySpinner extends Spinner {
OnItemSelectedListener listener;

public MySpinner(Context context, AttributeSet attrs) {
    super(context, attrs);
}

@Override
public void setSelection(int position) {
    super.setSelection(position);
    if (listener != null)
        listener.onItemSelected(null, null, position, 0);
}

public void setOnItemSelectedEvenIfUnchangedListener(
        OnItemSelectedListener listener) {
    this.listener = listener;
}
}
