I have the following views: a ViewPager that show 3 Fragments. The user can scroll horizontaly to see the others Fragment in the ViewPager.
I need to create an animation, when the Activity is created and the ViewPager is populated, that show the Fragments entering from the right side of the screen.
Is that even possible? Thanks.
XML:
<android.support.v4.view.ViewPager
android:id="#+id/devices"
android:layout_width="wrap_content"
android:layout_height="150dp" />
Activity:
MyFragmentStatePagerAdapter mAdapter = new MyFragmentStatePagerAdapter( this.getSupportFragmentManager(), fragmentArrayList );
mAdapter.setPageWidth(0.33333333f);
ViewPager devices = (ViewPager) view.findViewById(R.id.devices);
devices.setAdapter(sensorAdapter);
Adapter:
public class MyFragmentStatePagerAdapter extends FragmentStatePagerAdapter {
ArrayList<Fragment> fragmentsList;
private float pageWidth = 1;
public void setPageWidth(float pageWidth) { this.pageWidth = pageWidth; }
public MyFragmentStatePagerAdapter(FragmentManager fm, ArrayList<Fragment> fragmentsList) {
super(fm);
this.fragmentsList = fragmentsList;
}
#Override
public int getCount() {
return fragmentsList.size();
}
#Override
public Fragment getItem(int position) {
if (position<fragmentsList.size() & fragmentsList.get(position)!=null) {
return fragmentsList.get(position);
}
return null;
}
#Override
public float getPageWidth(int position) {
return(pageWidth);
}
}
OK, I found the solution. I just had to extend ViewPager and do the animation in onDraw.
This code is working as I needed:
public class ViewPagerCustom extends ViewPager {
private Context mContext;
private boolean startAnimationDone = false;
public ViewPagerCustom(Context context) {
super(context);
mContext = context;
init();
}
public ViewPagerCustom(Context context, AttributeSet attrs) {
super(context, attrs);
mContext = context;
init();
}
DisplayMetrics metrics;
TranslateAnimation anim;
private void init() {
metrics = mContext.getResources().getDisplayMetrics();
anim = new TranslateAnimation(metrics.widthPixels+200, 0, 0, 0);
anim.setInterpolator(new DecelerateInterpolator());
anim.setDuration(500);
}
private Canvas enterAnimation(Canvas c) {
startAnimationDone = true;
final int childCount = getChildCount();
for (int i = 0; i < childCount; i++) {
final View child = getChildAt(i);
child.startAnimation(anim);
}
return c;
}
#Override
protected void onDraw(Canvas c) {
if (startAnimationDone==false) {
c = enterAnimation(c);
}
super.onDraw(c);
}
}
Here is a link which might help you:
Zoom-out page transformer
It's similar to the accepted solution but uses the same interpolator and only changes the duration based on a factor. You need to use a ViewPagerCustomDuration in your XML instead of ViewPager, and then you can do this:
ViewPagerCustomDuration vp = (ViewPagerCustomDuration) findViewById(R.id.myPager);
vp.setScrollDurationFactor(2); // make the animation twice as slow

I have made an app in which I have added functionality of vertical swipe using ViewPager class. Now I need help to also add Horizontal swipe. I have seen several projects on GitHub for vertical & horizontal swipe together in same activity but could not figure out how can I integrate this with my code.
Here is how I implemented Vertical Swipe:

I am using ViewPager with FragmentStatePageAdapter to show a number of views where user can go through. With current implementation only one page is changed at any single swipe. Instead I want to flip through multiple views based on user swipe. If swipe is long/fast i need to flip through multiple views and vice versa.
here is my current code
public class MyAdapter extends FragmentStatePagerAdapter
{
public MyAdapter(FragmentManager fragmentManager) {
super(fragmentManager);
}
#Override
public int getCount() {
return 10;
}
#Override
public Fragment getItem(int position) {
return ItemFragment.init(position);
}
}
PageContainer class
public class PagerContainer extends FrameLayout implements ViewPager.OnPageChangeListener {
private ViewPager mPager;
boolean mNeedsRedraw = false;
public PagerContainer(Context context) {
super(context);
init();
}
public PagerContainer(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public PagerContainer(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
private void init() {
//Disable clipping of children so non-selected pages are visible
setClipChildren(false);
//Child clipping doesn't work with hardware acceleration in Android 3.x/4.x
//You need to set this value here if using hardware acceleration in an
// application targeted at these releases.
setLayerType(View.LAYER_TYPE_SOFTWARE, null);
}
#Override
protected void onFinishInflate() {
try {
mPager = (ViewPager) getChildAt(0);
mPager.setOnPageChangeListener(this);
} catch (Exception e) {
throw new IllegalStateException("The root child of PagerContainer must be a ViewPager");
}
}
public ViewPager getViewPager() {
return mPager;
}
private Point mCenter = new Point();
private Point mInitialTouch = new Point();

ev.offsetLocation(mCenter.x - mInitialTouch.x, mCenter.y - mInitialTouch.y);
break;
}
return mPager.dispatchTouchEvent(ev);
}
#Override

How can I do this in android?
Thanks
You can change the view by calling:
ViewPager.setCurrentItem(int index)
ViewPager.setCurrentItem(int index, bool animation)
You must handle the sliding commands yourself, but on a certain slide you cloud call setCurrentItem of the ViewPager. The setCurrentItem method also allows you to enable or disable animations.
I want to create a ViewPager, but when I execute the application in my phone, it shows me a blank activity and then the following error message:
The application testViewPager (process com.example.testviewpager) has stopped unexpectedly. Please try again.
How can I go about fixing this problem?

I am trying to show horizontal scroll view with images to scroll in two directions.Previously for this i used Gallery View but galleryview is deprected ,i am using horizontal scroll view instead of gallery view but horizontal scroll view is different with gallery view.
Now i have to do two implementation
1) Scrolling in two directions continuously.
2) Center lock feature as same as gallery.
My screen looks like
you can use viewpager,
try this code and modify it as your need .

I am writing application that uses ViewPager to host Fragments.
When I change fragment programmatically the smooth scroll function does not work. I use ViewPager.setCurrentItem(int item, boolean smoothScroll)` method.
Maybe anyone know a workaround this bug? Maybe with animations?
EDIT:
I am using support package. And the issue is that whether I use ViewPager.setCurrentItem(2, true) or ViewPager.setCurrentItem(2, false) the result is the same. The view switches really fast (not smoothly).
I've fixed this by creating a MyViewPager that overrides the ViewPager.mScroller using reflection.
public class MyViewPager extends ViewPager
{
public MyViewPager( Context context, AttributeSet attrs)
{
super( context, attrs );
setMyScroller();
}
private void setMyScroller()
{
try
{
Class<?> viewpager = ViewPager.class;
Field scroller = viewpager.getDeclaredField("mScroller");
scroller.setAccessible(true);
scroller.set(this, new MyScroller(getContext()));
} catch (Exception e)
{
e.printStackTrace();
}
}
public class MyScroller extends Scroller
{
public MyScroller(Context context)
{
super(context, new DecelerateInterpolator());
}
#Override
public void startScroll(int startX, int startY, int dx, int dy, int duration)
{
super.startScroll(startX, startY, dx, dy, 1000 /*1 secs*/);
}
}
}
What worked for me was to call mPager.setCurrentItem after the mPagerAdapter.notifyDataSetChanged(), and not as a posted runnable.
Here is an example (in MonoDroid):
public void UpdateDetialsView(string type)
{
string typeName4 = Java.Lang.Class.FromType(typeof(ParcelRecordComplaintDetailsView)).Name;
if (_fragments.Count > 3)
{
_fragments.RemoveAt(_fragments.Count - 1);
////////////////////////////////////////////////////////////
// Called here it wasn't working for me (Posted or not)
//_viewPager.Post(new Action(() => { _viewPager.SetCurrentItem(3, true); }));
}
_fragments.Add(Fragment.Instantiate(Activity, typeName4));
_pagerAdapter.NotifyDataSetChanged();
////////////////////////////////////////////////////////////
// Called here it works as expected
_viewPager.SetCurrentItem(3, true);
}
where
protected MyAdapter _pagerAdapter;
protected ViewPager _viewPager;
private List<Android.App.Fragment> _fragments;
and
public class MyAdapter : Android.Support.V13.App.FragmentStatePagerAdapter
{
private List<Fragment> _fragments;
public override Java.Lang.Object InstantiateItem(View p0, int p1)
{
return base.InstantiateItem(p0, p1);
}
public MyAdapter(Android.App.FragmentManager fm) : base(fm)
{
}
public MyAdapter(Android.App.FragmentManager fm, List<Android.App.Fragment> fragments) : base(fm)
{
_fragments = fragments;
}
public override int Count
{
//get { return FRAG_PAGES; }
get { return _fragments.Count; }
}
public override Android.App.Fragment GetItem(int p0)
{
return _fragments[p0];
}
public override float GetPageWidth(int p0)
{
//return base.GetPageWidth(p0);
return (float) (0.5f);
}
public override int GetItemPosition(Java.Lang.Object p0)
{
//return base.GetItemPosition(p0);
return PagerAdapter.PositionNone;
}
}
