Example of ListFragment inside DrawerLayout

This exercise implement android.app.ListFragment inside DrawerLayout. The ListFragment part refer to my another old post. If you are looking for ListView inside DrawLayout, read last post.

ListFragment inside DrawerLayout

In order to use android.app.ListFragment in your app, AndroidManifest.xml have to be modified to define android:minSdkVersion="11".

Create /res/layout/listfragment1.xml to define the layout of our ListFragment.

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

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

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

</LinearLayout>

Create MyListFragment1.java extends ListFragment.

package com.example.androiddrawerlayout;

import android.app.ListFragment;
import android.os.Bundle;

import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ListAdapter;
import android.widget.ListView;
import android.widget.Toast;

public class MyListFragment1 extends ListFragment {

 String[] month = { "January", "February", "March", "April", "May", "June",
   "July", "August", "September", "October", "November", "December" };

 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  ListAdapter myListAdapter = new ArrayAdapter<String>(getActivity(),
    android.R.layout.simple_list_item_1, month);
  setListAdapter(myListAdapter);
 }

 @Override
 public View onCreateView(LayoutInflater inflater, ViewGroup container,
   Bundle savedInstanceState) {
  return inflater.inflate(R.layout.listfragment1, container, false);
 }

 @Override
 public void onListItemClick(ListView l, View v, int position, long id) {
  // TODO Auto-generated method stub
  Toast.makeText(getActivity(),
    getListView().getItemAtPosition(position).toString(),
    Toast.LENGTH_LONG).show();
 }
}

Modify /res/layout/activity_main.xml to include <fragment> of "com.example.androiddrawerlayout.MyListFragment1" inside drawer.

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_height="match_parent" >

    <LinearLayout

        android:layout_height="match_parent"
        android:background="@android:color/background_light"
        android:orientation="vertical"
        android:paddingBottom="@dimen/activity_vertical_margin"
        android:paddingLeft="@dimen/activity_horizontal_margin"
        android:paddingRight="@dimen/activity_horizontal_margin"
        android:paddingTop="@dimen/activity_vertical_margin"
        tools:context=".MainActivity" >

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Main layout" />

        <Button

            android:text="Open Drawer" />

        <TextView
