Java – viewpager is called actvity after completion.

I'm developing an application. I have to use viewpager. After all the projects in viewpager are completed, I have to call an activity I can't get an event listener for this This is what I have been recommending: @ h_ 404_ 2@ https://github.com/chiuki/android-swipe-image-viewer/blob/master/src/com/sqisland/android/swipe_image_viewer/MainActivity.java

This is what I have done so far:

public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);
    ImagePagerAdapter adapter = new ImagePagerAdapter();
    viewPager.setAdapter(adapter);

    OnPagechangelistener mListener = new OnPagechangelistener() {

        @Override
        public void onPageSelected(int arg0) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onPageScrolled(int arg0,float arg1,int arg2) {

        }

        @Override
        public void onPageScrollStateChanged(int arg0) {
            Log.i("Doing something here","On Scroll state changed");
        }
    };
    viewPager.setOnPagechangelistener(mListener);

}

private class ImagePagerAdapter extends PagerAdapter {
    private int[] mImages = new int[] { R.drawable.libin1,R.drawable.libin2 };

    @Override
    public int getCount() {
        return mImages.length;

    }

    @Override
    public boolean isViewFromObject(View view,Object object) {
        return view == ((ImageView) object);
    }

    @Override
    public Object instantiateItem(ViewGroup container,int position) {
        Context context = MainActivity.this;
        ImageView imageView = new ImageView(context);
        int padding = context.getResources().getDimensionPixelSize(
                R.dimen.padding_medium);
        imageView.setPadding(padding,padding,padding);
        imageView.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
        imageView.setImageResource(mImages[position]);
        ((ViewPager) container).addView(imageView,0);
        return imageView;
    }

    @Override
    public void destroyItem(ViewGroup container,int position,Object object) {
        ((ViewPager) container).removeView((ImageView) object);
    }
}
}

My question is how to get the event listener if all the projects in the viewpager have been completed

Any kind of help will be greatly appreciated

Solution

private OnPagechangelistener mListener = new OnPagechangelistener() {

private OnPagechangelistener mListener = new OnPagechangelistener() {

    @Override
    public void onPageSelected(int arg0) {
        // TODO Auto-generated method stub
        selectedIndex = arg0;

    }
    boolean callHappened;
    @Override
    public void onPageScrolled(int arg0,int arg2) {
        // TODO Auto-generated method stub
        if( mPageEnd && arg0 == selectedIndex && !callHappened)
        {
            Log.d(getClass().getName(),"Okay");
            mPageEnd = false;//To avoid multiple calls. 
            callHappened = true;
        }else
        {
            mPageEnd = false;
        }
    }

    @Override
    public void onPageScrollStateChanged(int arg0) {
        // TODO Auto-generated method stub
        if(selectedIndex == adapter.getCount() - 1)
        {
            mPageEnd = true;
        }
    }
};
ViewPager.setOnPagechangelistener(mListener);

Onpagescrolled or onpageselected you can use any of these here and also check that the selected page is equal to the number of items in the viewpager
