由于某种原因，列表视图没有动画，只有文本视图。我感觉它与 LayoutInflater 有关，但我不确定。这是我定义 JazzyListView 及其动画的地方：
public class RssFragment extends Fragment implements AdapterView.OnItemClickListener {
private ProgressBar progressBar;
private View view;
private View view2;
private JazzyListView listView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setRetainInstance(true);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
if (view == null) {
view = inflater.inflate(R.layout.fragment_layout,container, false);
progressBar = (ProgressBar) view.findViewById(R.id.progressBar);
listView= (JazzyListView) view.findViewById(R.id.listView);
listView.setOnItemClickListener(this);
startService();
} else {
}
return view;
}
private void startService() {
Intent intent = new Intent(getActivity(), RssService.class);
intent.putExtra(RssService.RECEIVER, resultReceiver);
getActivity().startService(intent);
}
private final ResultReceiver resultReceiver = new ResultReceiver(new Handler()) {
@SuppressWarnings("unchecked")
@Override
protected void onReceiveResult(int resultCode, Bundle resultData) {
List<RssItem> items = (List<RssItem>) resultData.getSerializable(RssService.ITEMS);
if (items != null) {
RssAdapter adapter = new RssAdapter(getActivity(), items);
listView.setAdapter(adapter);
} else {
Toast.makeText(getActivity(), "The RSS feed is unable to be downloaded at this time",
Toast.LENGTH_LONG).show();
}
progressBar.setVisibility(View.GONE);
listView.setTransitionEffect(JazzyHelper.GROW);
listView.setVisibility(View.VISIBLE);
};
};
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
RssAdapter adapter = (RssAdapter) parent.getAdapter();
RssItem item = (RssItem) adapter.getItem(position);
Intent intent = new Intent(Intent.ACTION_VIEW);
startActivity(intent);
}
}
这是我的布局：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="wrap_content"
android:text="STAFF"

android:layout_centerHorizontal="true"

android:layout_toRightOf="@+id/button"
android:layout_toEndOf="@+id/button" />
</RelativeLayout>
正如我之前提到的，文本视图（文本视图本身位于不同的 xml 中）正在动画，但实际的列表视图不是。我已经尝试将片段更改为活动以消除视图/布局充气器。不知道还有什么可以尝试的。
[编辑 1] 这是 Android SDK 动画吗？这是来自 JazzyListView 库示例应用程序的图像...我的印象是 jazzylistview 也为列表视图设置了动画，否则有什么意义？？？
