Call activity after viewpager is finished

android, android-layout, android-viewpager, java, swipe

Solution

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, float arg1, 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` any of these you can use here and also check the selected page is equals to the number of items in the `ViewPager`.

Problem

I'm developing an application in which I have to use viewpager and after all items in viewpager is finished I have to call an activity. I'm not able to get event listener for this. Here is what I have been refering too: https://github.com/chiuki/android-swipe-image-viewer/blob/master/src/com/sqisland/android/swipe_image_viewer/MainActivity.java Here 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, 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 event listener if all the items in viewpager is finished.
