A simple exercise of Fragment, inflate layout from XML

Create a new Android project target Android 3.0.

Modify layout, main.xml, to add a our fragment.

<?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" >

   <TextView
       android:layout_width="0px"
       android:layout_weight="1"
       android:layout_height="match_parent"
       android:text="It's TextView in main Activity"
       android:background="#555555"/>
   <fragment
       class="com.exercise.FragmentTest.MyFragment"
       android:id="@+id/myfragment"
       android:layout_width="0px"
       android:layout_weight="4"
       android:layout_height="match_parent" />

</LinearLayout>

Implement /res/layout/fragmentlayout.xml, to define the layout of our fragment.

<?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="vertical" >
   <TextView
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       android:text="It's Fragment" />
   <ImageView
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:src="@drawable/ic_launcher"/>
</LinearLayout>

Add a new class MyFragment extends Fragment. Inside onCreateView(), inflate R.layout.fragmentlayout to generate our view and return it.

package com.exercise.FragmentTest;

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

public class MyFragment extends Fragment {

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

}

Keep the main activity no change from the auto-generated version.
