I've noticed that when you initialize a fragment with this ViewPager, navigate away then navigate 'Back'; an empty page is shown. After navigating back to this fragment, you can continue to swipe on the pager, then after X amount of items the view pager it against populated with more items.

Initializing a fragment with this ViewPager seems to work fine; however, coming back to a fragment that had already been created creates some blank pages.

Hello, I am facing the problem of class not found exception in my project when i used your code. And I am using your code with actionbar sherlock You are passing color array and I am passing image array. and I have already added your InfiniteViewPager.java and InfinitePagerAdapter as it is .

I am attching my Main Activity and main.xml and my fragment class file. so please check out and let me know the solution.

MainActivity:-

public class actMain extends SherlockFragmentActivity implements View.OnClickListener {

Button BTN_FACEBOOK;
ViewPager PAGER;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    initiatePageControls();

    startTour();
}

private void startTour() {
    PagerAdapter _adapter = new FragmentPagerAdapter(getSupportFragmentManager()) {
        int[] _images = new int[]{R.drawable.ic_launcher, R.drawable.a, R.drawable.b, R.drawable.c, R.drawable.d};

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

        @Override
        public Fragment getItem(int position) {
            Fragment _fragment = new frg_tour_slide();

            Bundle _args = new Bundle();
            _args.putInt("images", _images[position]);
            _args.putInt("position", position);
            _fragment.setArguments(_args);

            return _fragment;
        }
    };

    PagerAdapter _wrappedAdapter = new InfinitePagerAdapter(_adapter);
    PAGER.setAdapter(_wrappedAdapter);
}

private void initiatePageControls() {
    BTN_FACEBOOK = (Button) findViewById(R.id.btnFacebook);
    BTN_FACEBOOK.setOnClickListener(this);
    PAGER = (ViewPager) findViewById(R.id.pager);
}

@Override
public void onClick(View view) {
    if (view.getId() == BTN_FACEBOOK.getId()) {
        startActivity(new Intent(getApplicationContext(), actTestService.class));
        //startActivity(new Intent(getApplicationContext(), actFacebook.class));
    }
}

}

Fragment :- public class frg_tour_slide extends SherlockFragment {

ImageView SLIDE_1;
private int IMAGES;
private int IMAGE_POSITION;
private Context CONTEXT;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Bundle args = getArguments();
    IMAGES = args.getInt("images");
    IMAGE_POSITION = args.getInt("position");
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View _view = inflater.inflate(R.layout.tour_slide, null);

    SLIDE_1 = (ImageView) _view.findViewById(R.id.imgSlideShow);
    SLIDE_1.setImageResource(IMAGES);

    return _view;
}

@Override
public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    outState.putBoolean("dummy", true);
}

}

Please help me for this issue. Thanking you in advance.

Hello, i used your this custom infinite view pager for rotate globe with custom images but currently its scrolling speed is slow so how to increase its scrolling speed or make it smooth scroll. I want to give scrolling speed dynamically. Please give me any solution or positive response. Thanks

Love your code... it's exactly what I've been looking for. I can't use it in my app though unless I know the terms of the license. Would you mind adding a license to your repository? Thanks so much!!!!

Ingrid

That's because setPrimaryItem() is not forwarded to set adapter instance. To make it work, add the method below to InfinitePagerAdapter class:

@Override
public void setPrimaryItem(ViewGroup container, int position, Object object) {
    adapter.setPrimaryItem(container, position, object);
}

Inside setPrimaryItem() FragmentPagerAdapter calls setMenuVisibility() on fragments to ensure only one would get menu callbacks. Without calling setPrimaryItem() all fragments have menu visibility set to false by default.

I have many user delight items in my app that need to surface when, or shortly after, a user swipes to a tab and that tab is made visible. I was using a regular viewpager before and this was no issue. Can't seem to find where/how I might get the InfiniteViewPager to do this. May need to hack the support-v4 library and recompile jar.

This updates:

1. Gradle wrapper
2. Android Gradle plugin (this required removing buildToolsVersion)
3. Android Maven plugin (I'm not sure how to test this, but the old version didn't work with the rest of the changes)
4. Support library (this required bumping up minSdkVersion and compileSdkVersion) - I also started using the specific packages that are required, rather than the whole kitchen-sink support library, to reduce the size

Since setCurrentItem() refers to a "real" position and not "virtual" position, override the implementation of getCurrentItem() to reflect this. It now returns the actual position of the object that is backing the adapter.

Also fixes #8 setCurrentItem(int, boolean) has the same implementation as setCurrentItem(int) except with smoothScroll

Overridden getCurrentItem() to reflect the actual object position that corresponds to the position in the data backing the adapter. Similar to setCurrentItem().

Hello,

 I would like to get the current Item from InfiniteViewPager. I have tried to get the current item. But I haven't got the current Item. Is there any way to get the current item?

Thanks. julia.

Is there any metghod to get actual current position method, pager.getCurrentRealPosition() is not providing me actual position, and i have call setCurrentRealPosition at last of currentItem method.

override fun setCurrentItem(item: Int, smoothScroll: Boolean) { var item = item if (adapter!!.count == 0) { super.setCurrentItem(item, smoothScroll) return } item = offsetAmount + item % adapter!!.count super.setCurrentItem(item, smoothScroll) setRealCurrentItem(item, true) }

Hi, i want to user tablayout with infiniteviewpager. Can someone guide me.

Right now i am facing an issue while using it,

Process: com.kotlin.mNative, PID: 7342 java.lang.OutOfMemoryError: Failed to allocate a 108832 byte allocation with 102312 free bytes and 99KB until OOM, max allowed footprint 268435456, growth limit 268435456 at android.view.ViewGroup.addInArray(ViewGroup.java:5361) at android.view.ViewGroup.addViewInner(ViewGroup.java:5274) at android.view.ViewGroup.addView(ViewGroup.java:5083) at com.google.android.material.tabs.TabLayout.addTabView(TabLayout.java:1370) at com.google.android.material.tabs.TabLayout.addTab(TabLayout.java:620) at com.google.android.material.tabs.TabLayout.addTab(TabLayout.java:605) at com.google.android.material.tabs.TabLayout.populateFromPagerAdapter(TabLayout.java:1323) at com.google.android.material.tabs.TabLayout.setPagerAdapter(TabLayout.java:1314) at com.google.android.material.tabs.TabLayout.setupWithViewPager(TabLayout.java:1227) at com.google.android.material.tabs.TabLayout.setupWithViewPager(TabLayout.java:1188)

Hey bro auto scroll crash while using this library this is my logcat

java.lang.NullPointerException: Attempt to invoke virtual method 'int android.support.v4.view.PagerAdapter.getCount()' on a null object reference

In my case, I play loop it in the timertask and change viewpagerTransform every time (It's like random animation),But there will always be a blank page at some time.

private Handler mh = new Handler() {
        @Override
        public void handleMessage(Message msg) {
            super.handleMessage(msg);
            moveNextPosition();
       }
};

Any help is greatly appreciated
