我在让ListFragment垂直填充屏幕时遇到问题。它在数据加载时填充正常,但是一旦我调用setListShown(true),它就会收缩到wrap_content。我更改了fragmentContainer的背景并验证它也在缩小。我正在开发2.3.3手机。
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.main);
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
if(savedInstanceState == null){
Queues qs = new Queues();
fragmentTransaction.add(R.id.fragmentContainer, qs);
fragmentTransaction.commit();
}
}
<LinearLayout android:id="@+id/fragmentContainer"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
编辑: 这是完整的布局代码:
