// set wallpaper on button click
Button b1 = (Button) findViewById(R.id.wll);
b1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v2) {
// // TODO Auto-generated method stub
WallpaperManager myWallpaperManager = WallpaperManager
.getInstance(getApplicationContext());
try {
myWallpaperManager.setResource(R.id.view_pager);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});

package com.td.gridview;

public class SwipeActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.swipe_view);
// get intent data
Intent i = getIntent();
// Selected image id
final int position = i.getExtras().getInt("id");
ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);
ImagePagerAdapter adapter = new ImagePagerAdapter();
viewPager.setAdapter(adapter);
viewPager.setCurrentItem(position);
// send image to full_view.xml screen on button click
Button b = (Button) findViewById(R.id.xoom);
b.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// // TODO Auto-generated method stub
// get intent data
Intent i3 = getIntent();
// Selected image id
int position = i3.getExtras().getInt("id");
// Sending image id to FullScreenActivity
Intent i2 = new Intent(getApplicationContext(), Full_Zoom.class);
// passing array index
i2.putExtra("id", position);
startActivity(i2);
}
});
//
// set wallpaper on button click
Button b1 = (Button) findViewById(R.id.wll);
b1.setOnClickListener(new View.OnClickListener() {

public class ImagePagerAdapter extends PagerAdapter {

return icons.length;
}
@Override
public boolean isViewFromObject(View view, Object object) {
return view == ((ImageView) object);
}
@Override
public Object instantiateItem(ViewGroup container, int position) {
Context context = SwipeActivity.this;
ImageView imageView = new ImageView(context);
// int padding = context.getResources().getDimensionPixelSize(
// R.dimen.padding_large);
// imageView.setPadding(padding, padding, padding, padding);
imageView.setScaleType(ImageView.ScaleType.FIT_CENTER);
imageView.setImageResource(icons[position]);
((ViewPager) container).addView(imageView, 0);
return imageView;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
