Thread: I've created a slideshow using ViewPager, need to make a 3 small changes but stuck

I wanted to create a simple slideshow. I've gotten reasonably far, but now I'm stuck, I'm sure my issues sound very simple to you guys, hence why I'm here looking for help :-) I have made an effort, source code below.


Changes I'm stuck on

1. I want the images of the slideshow to fill the screen
2. I also don't want the user to have to drag the image across, I just want him to tap the image and it goes to the next one.
3. When the slideshow ends (reaches last item, a toast message tells user its finished)

I have tried to do the above, but like I said. I'm abit new at all this

ImagePager:

    public class ImagePager extends Activity {
 
    	@Override
    	public void onCreate(Bundle savedInstanceState) {
    		super.onCreate(savedInstanceState);
    		setContentView(R.layout.activity_main);
    		ImagePagerAdapter adapter = new ImagePagerAdapter(this, imageArra );
    		ViewPager myPager = (ViewPager) findViewById(R.id.myimagepager);
    		myPager.setAdapter(adapter);
    		myPager.setCurrentItem(0);
    		}
 
 
    	private int imageArra[] = { R.drawable.one, R.drawable.two, R.drawable.three, R.drawable.four,

    			                    R.drawable.nine,R.drawable.ten,R.drawable.eleven, R.drawable.twelve,

    		im.setImageResource(imageArray[position]);

               return layout;
