AndroidView v2.0 - Creating a Layout in Resource File

This section provides a tutorial example on how to create a LinearLayout object with 2 Button objects in the layout resource file. No layout objects are create in this example.

As I mentioned earlier, UI components can also be defined in layout resource files. Now let's try to build AndroidView version 2 with the LinearLayout and Button objects defined in a layout resource file.

First modify the main layout resource file, .\res\layout\main.xml:

<?xml version="1.0" encoding="utf-8"?>
<!-- AndroidView_layout.xml
 - Version 2.0 - Using layout resource file
 - Copyright (c) 2015,, All Rights Reserved.

Then modify the Java class code, .\src\com\herongyang\view\

 * Version 2.0 - Using layout resource file
 * Copyright (c) 2015,, All Rights Reserved.
package com.herongyang.view;

import android.os.Bundle;
public class AndroidView extends Activity {
   public void onCreate(Bundle savedInstanceState) {

      // Set the layout as the activity content

Things to remember when using layout resource files:

After building and installing the project, what I see when running AndroidView on the emulator is similar to this:
