我试图通过返回自己的视图层次结构来自定义片段布局onCreateView(LayoutInflater, ViewGroup, Bundle)。这膨胀了我的自定义视图,但似乎堆叠的意见,而不是内部膨胀,我看到一切。

MyActivity.java:

public class MyActivity extends FragmentActivity{
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        if (getSupportFragmentManager().findFragmentById(android.R.id.content) == null) {
            ArrayListFragment list = new ArrayListFragment();
            getSupportFragmentManager().beginTransaction().add(android.R.id.content, list).commit();
        }
    }

    public static class ArrayListFragment extends ListFragment {

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
            inflater.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
            inflater.inflate(R.layout.main, container);
            return super.onCreateView(inflater, container, savedInstanceState);
        }

        @Override
        public void onActivityCreated(Bundle savedInstanceState) {
            super.onActivityCreated(savedInstanceState);
            String List[] = {"Larry", "Moe", "Curly"}; 
            setListAdapter(new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, List));
        }
    }
}

main.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:paddingLeft="8dp"
  android:paddingRight="8dp">

  <Button
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="THIS IS A BUTTON" />

  <ListView
    android:id="@android:id/list"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#00FF00"
    android:layout_weight="1"
    android:drawSelectorOnTop="false" />

  <TextView
    android:id="@android:id/empty"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#FF0000"
    android:text="No data" />
</LinearLayout>

我没有在ListFragment类的onCreateView方法中返回新视图。例如:

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
            View view = inflater.inflate(R.layout.main, null);
            return view;
        }

这样的方法相信对你有用哦:

 @Override
 public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle  savedInstanceState) {
 View root = inflater.inflate(R.layout.main, container, false);
 return root;
 }
