Try to use ViewFlipper instead of viewpager

Layout xml

Activity

public class SlideShowActivity extends Activity  {



ViewFlipper imageFrame;
Button slideShowBtn;
Handler handler;
Runnable runnable;
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.photo_slideshow_main);
    imageFrame = (ViewFlipper) findViewById(R.id.imageFrames);

            //get sd card path for images

    File parentFolder = new
     File(Environment.getExternalStorageDirectory()
     .getAbsolutePath()
     + "/images");

    addFlipperImages(imageFrame, parentFolder);

    handler = new Handler();
    imageFrame.setOnClickListener(SlideShowActivity.this);

    slideShowBtn = (Button) findViewById(R.id.slideShowBtn);
    slideShowBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg0) {

            runnable = new Runnable() {

                @Override
                public void run() {
                    handler.postDelayed(runnable, 3000);
                    imageFrame.showNext();

                }
            };
            handler.postDelayed(runnable, 500);
        }
    });

}

private void addFlipperImages(ViewFlipper flipper, File parent) {
    int imageCount = parent.listFiles().length;
    RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.FILL_PARENT,
            RelativeLayout.LayoutParams.FILL_PARENT);
    for (int count = 0; count < imageCount - 1; count++) {
        ImageView imageView = new ImageView(this);
        Bitmap imbm = BitmapFactory.decodeFile(parent.listFiles()[count]
                .getAbsolutePath());
        imageView.setImageBitmap(imbm);
        imageView.setLayoutParams(params);
        flipper.addView(imageView);
    }

}

}

@Override
public void onClick(View view) {

}
}
