ListFragment

ListFragment (for API Level 11, Android 3.0, or higher) hosts a ListView object that can be bound to different data sources, typically either an array or a Cursor holding query results. Binding, screen layout, and row layout are discussed in the following sections.



Create a new /res/layout/listfragment1.xml file, it's the layout of out ListFragment.
(If the list is empty, the TextView empty will be shown.)

<?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">

     <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 a new MyListFragment1.java class, extends com.exercise.AndroidListFragment. Override onCreate(), onCreateView() and onListItemClick() methods.

package com.exercise.AndroidListFragment;

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();
 }
}

Add another dummy Fragment.

Create a new /res/layout/fragment2.xml, the layout of the second Fragment.

<?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" >
    
    <TextView
        android:id="@+id/fragment2text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Hello! It's Fragment2" />
</LinearLayout>

Fragment2.java, extends android.app.Fragment. Override onCreateView() method.

package com.exercise.AndroidListFragment;

import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class Fragment2 extends Fragment {

 @Override
 public View onCreateView(LayoutInflater inflater, ViewGroup container,
   Bundle savedInstanceState) {
  // TODO Auto-generated method stub
  return inflater.inflate(R.layout.fragment2, container, false);
 }

}

Modify main.xml to include both Fragments

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal" >

  <fragment
      android:name="com.exercise.AndroidListFragment.MyListFragment1"
      android:id="@+id/fragment1"
      android:layout_weight="1"
      android:layout_width="0px"
      android:layout_height="match_parent" />
  <fragment
      android:name="com.exercise.AndroidListFragment.Fragment2"
      android:id="@+id/fragment2"
      android:layout_weight="2"
      android:layout_width="0px"
      android:layout_height="match_parent" />

</LinearLayout>
