ListView CAB检查项着色

Question

我不知所措，因为我觉得android应该处理这个默认的选择行为.

我使用了带有listview的actionbarsherlock，并在项目长单击后出现了一个上下文操作栏。我希望这些项目出现后，长时间点击突出显示，但他们只是做最初的闪黑蓝色，然后他们恢复到他们的默认颜色。我是不是遗漏了什么？

    mHabitListView.setAdapter(mAdapter);
    mHabitListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
    mHabitListView.setOnItemLongClickListener(new OnItemLongClickListener() {

        @Override
        public boolean onItemLongClick(AdapterView<?> parent, View view,
                int position, long id) {

                if (mHabitListView.isItemChecked(position)){
                    mHabitListView.setItemChecked(position, false);


                } else {
                    mHabitListView.setItemChecked(position, true);

                }

                if (mHabitListView.getCheckedItemCount() > 0) {

                    if (mMode == null) {
                        mMode = startActionMode(new ModeCallback());
                    } else {
                        mMode.setTitle(mHabitListView.getCheckedItemCount() + " " + getString(R.string.cab_selected_count));

                    }
                } else {
                    if (mMode != null) {
                        mMode.finish();

                    }
                }
                return true;
            }

    });






}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getSupportMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}

@Override

    // Handle item selection
    switch (item.getItemId()) {
        case R.id.menu_add_new_habit:
            Habit h = new Habit("Floss", "GOOD", "", "");

            mDbHelper.createHabitEntry(h);
            mDbHelper.close();

            Cursor cursor =  mDbHelper.getAllEntries();
            mAdapter.changeCursor(cursor);

            break;
    }
    return true;
}



 private final class ModeCallback implements ActionMode.Callback {

        @Override
        public boolean onCreateActionMode(ActionMode mode, Menu menu) {
            // Create the menu from the xml file
            MenuInflater inflater = getSupportMenuInflater();
            mode.setTitle(mHabitListView.getCheckedItemCount() + " " + getString(R.string.cab_selected_count));
            inflater.inflate(R.menu.list_contextual_menu, menu);
            return true;
        }

        @Override
        public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
            // Here, you can checked selected items to adapt available actions
            return false;
        }

        @Override
        public void onDestroyActionMode(ActionMode mode) {
            // Destroying action mode, let's unselect all items
            for (int i = 0; i < mHabitListView.getAdapter().getCount(); i++)
                mHabitListView.setItemChecked(i, false);

            if (mode == mMode) {
                mMode = null;
            }
        }

        @Override
        public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
            long[] selected = mHabitListView.getCheckedItemIds();
            if (selected.length > 0) {
                for (long id: selected) {
                    // Do something with the selected item
                }
            }
            mode.finish();
            return true;


        }

将Listitem的背景设置为android:background="?android:attr/activatedBackgroundIndicator"

如果仍然面临任何问题，请尝试从listSelector xml中删除ListView属性。
