Android + ListFragment with a custom view hierarchy

worked picture worked · Sep 23, 2011 · Viewed 24.6k times · Source

I'm attempting to customize the fragment layout by returning my own view hierarchy from onCreateView(LayoutInflater, ViewGroup, Bundle). This inflates my custom view, but seems to stack the views instead of inflating within, I see everything at once. Any help is appreciated.

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>

I wasn't returning the new view within the onCreateView method of the ListFragment class. For instance:

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

All works well now in the land of Android!
