Image Switcher & Gallery in Android

Step 1 : create a simple Linear-layout with an ImageSwitcher & a gallery view.

Step 2: include neccessary animation xml files , like fade in, fade out.   

public class MyImageSwitcher extends Activity implements
        AdapterView.OnItemSelectedListener, ViewSwitcher.ViewFactory {
 
// create array of thumbnail & image Ids 
private Integer[] mThumbIds = {  
      R.drawable.homeapp1,R.drawable.homeapp3,R.drawable.homeapp4};
    private Integer[] mImageIds = {R.drawable.homeapp1,R.drawable.homeapp3,R.drawable.homeapp4};
 
 String category;
 ViewFlipper mFlipper;
  private ImageSwitcher mSwitcher;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);

        setContentView(R.layout.image_switcher_1);

        mSwitcher = (ImageSwitcher) findViewById(R.id.switcher);
        mSwitcher.setFactory(this);
        mSwitcher.setInAnimation(AnimationUtils.loadAnimation(this,
                android.R.anim.fade_in));
        mSwitcher.setOutAnimation(AnimationUtils.loadAnimation(this,
                android.R.anim.fade_out));

        Gallery g = (Gallery) findViewById(R.id.gallery);
        g.setAdapter(new ImageAdapter(this));
        g.setOnItemSelectedListener(this);
    }

    public void onItemSelected(AdapterView parent, View v, int position, long id) {   
     mSwitcher.setImageResource(mImageIds[position]);
    }

    public void onNothingSelected(AdapterView parent) {
    }

    public View makeView() {
        ImageView i = new ImageView(this);
        i.setBackgroundColor(0xFF000000);
        i.setScaleType(ImageView.ScaleType.FIT_CENTER);
        i.setLayoutParams(new  ImageSwitcher.LayoutParams(LayoutParams.FILL_PARENT,
                LayoutParams.FILL_PARENT));
        return i;
    }

    public class ImageAdapter extends BaseAdapter {
        //write your own implementation for returning Images from getView method

    }    
}
