突出显示和QUOT选择的​​项目; ListFragment＆QUOT;？ [英] Highlight selected item in "ListFragment"?

问题描述

我已经发布了同样的问题了几次，却一直没有得到解决。我有一个 ListFragment ，我想强调，在列表中选择的项目。我一直在考虑建议使用选择。我不知道如何使用这个选择。我的 ListFragment 类：

I have posted the same problem a couple of times but it hasn't yet been resolved. I have a ListFragment and I want to highlight the selected item in the list. I have been given suggestions to use a "selector". I don't understand how to use this selector. My ListFragment class is:

// Create an adapter with list of stores and populate the list with
        // values
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(),
                android.R.layout.simple_list_item_1, StoreList);
        setListAdapter(adapter);
        mDbHelper.close();
    }

    /*
     * (non-Javadoc)
     * 
     * Handles the event when an item is clicked on left pane, performs action
     * based on the selection in left pane
     *  
     * @see android.app.ListFragment#onListItemClick(android.widget.ListView,
     * android.view.View, int, long)
     */
    @Override
    public void onListItemClick(ListView l, View v, int position, long id) {
        String selectedStore = (String) getListAdapter().getItem(position);
        DetailFragment fragment = (DetailFragment) getFragmentManager()
                .findFragmentById(R.id.detailFragment);
        if (fragment != null && fragment.isInLayout()) {
            v.setBackgroundColor(getResources().getColor(R.color.BLUE));
            // passes selectedStore to detail fragment  
            fragment.setText(selectedStore);

            // getItemList(selectedStore);

        }

使用的setBackground设置永久的颜色，但我希望在其他项目中选择它去走。 我知道如何使用选择在的ListView 但对我来说，如果我还没有定义任何XML为列表视图，那么我将如何使用选择？我使用 android.R.layout.simple_list_item_1 这是pdefined $ P $。

Using setBackground sets the color permanently, but I want it to go away when another item is selected. I understand how to use a selector in a ListView but in my case if I haven't defined any xml for the Listview, then how would I use a "selector"? I am using android.R.layout.simple_list_item_1 which is predefined.

推荐答案

我没有得到我想要的东西，所以我不停地挖，并提出了这可能不是最好的做法是便宜的解决方案，但没有工作。 我想选择时，该项目被突出显示，并且颜色应该走在其他项目是从listFragment选择。 这是我定义的静态什么工作我 - 视图V; 并初始化它 V =新景（getActivity（））; 然后在我的

I wasn't getting what I wanted so I kept on digging and came up with a "cheap" solution which might not be the best practice but does the job. I wanted the item to be highlighted when selected and the color should go away when other item is selected from the listFragment. This is what worked for me- I defined a static View V; and initialized it V = new View(getActivity()); Then inside my

onListItemClick（ListView的L，视图V ，INT位置，长ID）

onListItemClick(ListView l, View v, int position, long id)

            V.setBackgroundResource(0);
            v.setBackgroundResource(R.color.BLUE);
            V = v;
