XML:
<ListView
android:id="@android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
JAVA:
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);
}
现Activated_background为
<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,我遇到下一个异常:

如果我从代码中删除
getListView().setSelector(R.drawable.activated_background);
,并以XML作为我的列表的自定义行的背景将其移动:<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+版本,但在2.3中选定的行不会毫无例外地突出显示。
欢迎任何帮助。
最佳答案
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?
