XML:

<ListView
        android:id="@android:id/list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

爪哇：

import org.holoeverywhere.app.ListFragment;
import org.holoeverywhere.widget.ListView;
    ....
    ....
private void listViewInit() {
    getListView().setOnItemClickListener(this);
    getListView().setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
    getListView().setMultiChoiceModeListener(getMultiChoiceModeListener());
    getListView().setSelector(R.drawable.activated_background); // Error there
    setListAdapter(adapter);
}

激活的背景是

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_activated="true" android:drawable="@color/row_activated"/>
    <item android:drawable="@android:color/transparent"/>
</selector>

在模拟器（android 2.3.3）中，当 ListView 附近出现在屏幕上时，我有下一个异常：

如果我从代码中删除getListView().setSelector(R.drawable.activated_background);，并将其作为我列表自定义行的背景移动到 XML 中：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="@drawable/activated_background">
....
</RelativeLayour>

它适用于 4+，但在 2.3 选定的行中没有任何例外地突出显示。

欢迎任何帮助。

我花了超过 1 天的时间，最后我开始使用这个愚蠢的决定：

@Override
public void onItemCheckedStateChanged(ActionMode actionMode, int i, long l, boolean b) {
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.HONEYCOMB) {
        if (b)
            listView.getChildAt(i).setBackgroundColor(activity.getResources().getColor(R.color.row_activated));
        else
            listView.getChildAt(i).setBackgroundColor(activity.getResources().getColor(R.color.abs__background_holo_dark));
    }

也许有人知道如何以更“正常”的方式解决它？
