这段代码有什么不好的吗？

问题是"测试"没有显示在ListView.

Java的:

private ListView namesListView;
private ArrayList<String> names;
private ArrayAdapter<String> namesAA;
...
namesListView = (ListView)findViewById(R.id.list);
names = new ArrayList<String>();
names.clear();
names.add(0, "test");
namesAA = new ArrayAdapter<String> ( this, android.R.layout.simple_list_item_1, names );
namesListView.setAdapter(namesAA);
...

XML:

<ListView 
    android:id="@+id/list"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
/>
