These days I am working on an Android Wallpaper app tutorial. In this android wallpaper app example source code, I will list all available wallpaper thumbnail images in two modes. In the list mode, I will show all wallpaper image in a list with their information like download counter and votes. In the grid mode, I will list all wallpapers in a gridview. In this tutorial, I will show you how to create a GridView in an activity and how to generate all image item in a GridView in android. After all, you can download this example app and example source code to use in your own project.

This Android Wallpaper App example includes four tutorials:

Create a New Android Project in Eclipse

First of all, let’s create an Android project in Eclipse. I am using Eclipse 4.2.2 with Android SDK 22.3. The project will target to API 19, Android 4.4.2, compatible with minimum required SDK API 8 for Android 2.2. Follow the steps to create a new project first.

Place GridView in Layout XML

After we create a project, we will get a xml file in the layout folder. Now, we can edit this layout xml to add a grid view in main layout. Here is the example source code:

<RelativeLayout xmlns:android=""
    tools:context=".MainActivity" >


Generate Image Item in GridView

To make this example simple to understand, I am using some dummy data first. In future tutorial, we can load a wallpaper list from server so that we can show the available wallpaper dynamically. In this example, I put 8 images in res folder and define an Integer array in Activity class. Here is the source code:

	private Integer[] wallpaperThumbIntegers = {
			R.drawable.thumb1, R.drawable.thumb2,
			R.drawable.thumb3, R.drawable.thumb4,
			R.drawable.thumb5, R.drawable.thumb6,
			R.drawable.thumb7, R.drawable.thumb8

Then, I define a inner class called ImageAdapter which will be in charge of generate all ImageView for GridView. Here is the source code:

	protected class ImageAdapter extends BaseAdapter {
		private Context mContext;
		public ImageAdapter(Context c) {
			mContext = c;

		public int getCount() {
			// TODO Auto-generated method stub
			return wallpaperThumbIntegers.length;

		public Object getItem(int position) {
			// TODO Auto-generated method stub
			return null;

		public long getItemId(int position) {
			// TODO Auto-generated method stub
			return 0;

		public View getView(int position, View convertView, ViewGroup parent) {
			// TODO Auto-generated method stub
			ImageView imageView;
			if(convertView == null) {
				imageView = new ImageView(mContext);
				imageView.setLayoutParams(new GridView.LayoutParams(216, 162));
			} else {
				imageView = (ImageView) convertView;
			return imageView;

In last step, I will set the ImageAdapter to gridView in onCreate function of Activity class. Here is the source code:

	protected void onCreate(Bundle savedInstanceState) {
		GridView gridView = (GridView) findViewById(;
		gridView.setAdapter(new ImageAdapter(this));

Let’s run the app and see how it looks like.
