I would like to create a ViewPager whose width wrap's to its contents, and is centered horizontally in it's parent. The first code snippet uses a LinearLayout to create this effect, as shown in the first screenshot. The second code snippet is my attempt to do this with a ViewPager instead of the LinearLayout, but the result is not the desired behavior, as shown in the second screenshot.
Any suggestions as to how I create the first effect, but using a ViewPager?
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
textView = new TextView(this);
textView.setLayoutParams(new ViewGroup.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT));
textView.setText("abcabcabcabcabc");
textView.setBackgroundColor(Color.YELLOW);
LinearLayout llayout = new LinearLayout(this);
llayout.setBackgroundColor(Color.BLUE);
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.MATCH_PARENT);
layoutParams.addRule(RelativeLayout.CENTER_HORIZONTAL);
llayout.setLayoutParams(layoutParams);
llayout.addView(textView);
layout = new RelativeLayout(this);
layout.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
layout.setBackgroundColor(Color.GREEN);
layout.addView(llayout);
setContentView(layout);
}
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
textView = new TextView(this);
textView.setLayoutParams(new ViewGroup.LayoutParams(ViewPager.LayoutParams.WRAP_CONTENT, ViewPager.LayoutParams.WRAP_CONTENT));
textView.setText("abcabcabcabcabc");
textView.setBackgroundColor(Color.YELLOW);
ViewPager pager = new ViewPager(this);
pager.setBackgroundColor(Color.BLUE);
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.FILL_PARENT);
layoutParams.addRule(RelativeLayout.CENTER_HORIZONTAL);
pager.setLayoutParams(layoutParams);
pager.setAdapter(new ViewPagerAdapter());
layout = new RelativeLayout(this);
layout.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
layout.setBackgroundColor(Color.GREEN);
layout.addView(pager);
setContentView(layout);
}
class ViewPagerAdapter extends PagerAdapter
{
#Override
public int getCount()
{
return 1;
}
public Object instantiateItem(ViewGroup collection, int position)
{
collection.addView(textView, 0);
return textView;
}
#Override
public void destroyItem(ViewGroup collection, int position, Object view)
{
collection.removeView((View) view);
}
#Override
public boolean isViewFromObject(View view, Object object)
{
return (view==object);
}
#Override
public void finishUpdate(ViewGroup arg0) {}
#Override
public void restoreState(Parcelable arg0, ClassLoader arg1) {}
#Override

}
#Override

}
If you look at your code for where Adapter called instantiateItem()
public Object instantiateItem(ViewGroup collection, int position)
{
collection.addView(textView, 0)
return textView;
}
You are returning a TextView to be the page and the ONLY thing that you want to show.
The relevant part of the documentation is here:
http://developer.android.com/reference/android/support/v4/view/PagerAdapter.html
A very simple PagerAdapter may choose to use the page Views themselves
as key objects, returning them from instantiateItem(ViewGroup, int)
after creation and adding them to the parent ViewGroup. A matching
destroyItem(ViewGroup, int, Object) implementation would remove the
View from the parent ViewGroup and isViewFromObject(View, Object)
could be implemented as return view == object;.
Create a View with the layout that you want and return it there to have the effect you desire.

I have used viewpager which displays view with an image and radiobutton below. Each swipe screen is not a fragment, they are layouts which just swipe the same view with different imageview. The problem is that, I am unable to deselect the radio button which is in left and right side of the current view after i select the radio button of the current screen. If I return POSITION_NONE in getItemPosition(), it refresh the screen and radio button also deselected but the view is flickered. If i am able to call instantiateItem(), my problem is solved . But this method is called only when view is destroyed based on the setOffsetScreenPageLimit(). How can I achieved such requirements, if view pager cannot help?

I am using PagerSlidingTabStrip with a ViewPager.
Is there a way I can change the Tab icons dynamically, depending on some actions. Like when a notification is received, I want to change the icon on notifications tab to show how many notifications are unread.
Or any other library which would support that without much tweaking.
You can do it by implementing PagerSlidingTabStrip.CustomTabProvider interface. I made example project for your case, so let's explore it step by step.
Firstly, create a layout for our tab called tab_layout, for example. It will contain 2 TextView's for title and badge. In my case it looks like:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/tab_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:gravity="center"
android:textColor="#android:color/white"
android:textStyle="bold"
android:textSize="16sp"
android:singleLine="true" />
<TextView
android:id="#+id/badge"
android:layout_width="16dp"
android:layout_height="16dp"
android:layout_toRightOf="#+id/tab_title"
android:textSize="12sp"
android:gravity="center"
android:layout_marginLeft="8dp"
android:layout_centerVertical="true"
android:textColor="#android:color/white"
android:background="#drawable/badge_background" />
</RelativeLayout>
Secondly, create a simple model for Tab, that will containt a tab title and number of notifications. I've called it ViewPagerTab:
public class ViewPagerTab {
public String title;
public int notifications;
public ViewPagerTab(String title, int notifications) {
this.title = title;
this.notifications = notifications;
}
}
Thirdly, implement PagerSlidingTabStrip.CustomTabProvider interface on your FragmentPagerAdapter. Here we will inflate tab layout and initialize the tab views, also we will define fragments for positions:
public class MainAdapter extends FragmentPagerAdapter
implements PagerSlidingTabStrip.CustomTabProvider {
ArrayList<ViewPagerTab> tabs;
public MainAdapter(FragmentManager fm, ArrayList<ViewPagerTab> tabs) {
super(fm);
this.tabs = tabs;
}
#Override
public View getCustomTabView(ViewGroup viewGroup, int i) {
RelativeLayout tabLayout = (RelativeLayout)
LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.tab_layout, null);
TextView tabTitle = (TextView) tabLayout.findViewById(R.id.tab_title);
TextView badge = (TextView) tabLayout.findViewById(R.id.badge);
ViewPagerTab tab = tabs.get(i);
tabTitle.setText(tab.title.toUpperCase());
if (tab.notifications > 0) {
badge.setVisibility(View.VISIBLE);
badge.setText(String.valueOf(tab.notifications));
} else {
badge.setVisibility(View.GONE);
}
return tabLayout;
}
#Override
public void tabSelected(View view) {
//if you don't want badges disappear when you select tab comment next lines
RelativeLayout tabLayout = (RelativeLayout) view;
TextView badge = (TextView) tabLayout.findViewById(R.id.badge);
badge.setVisibility(View.GONE);
}
#Override
public void tabUnselected(View view) {
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new OneFragment();
case 1:
return new TwoFragment();
case 2:
return new ThreeFragment();
}
return new OneFragment();
}
#Override
public int getCount() {
return tabs.size();
}
}
Fourthly, initialize tabs and pager in MainActivity's onCreate method:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tabs = (PagerSlidingTabStrip) findViewById(R.id.tabs);
pager = (ViewPager) findViewById(R.id.pager);
ArrayList<ViewPagerTab> tabsList = new ArrayList<>();
tabsList.add(new ViewPagerTab("One", 0));
tabsList.add(new ViewPagerTab("Two", 1));
tabsList.add(new ViewPagerTab("Three", 2));
adapter = new MainAdapter(getSupportFragmentManager(), tabsList);
pager.setAdapter(adapter);
tabs.setViewPager(pager);
pager.setOffscreenPageLimit(3);
getSupportActionBar().hide();
}
You will get something like this:
And finally, to get and change tab views in runtime, you can simply call getChildAt function of PagerSlidingTabStrip object in your Activity or Fragment, and do what you want:
private void notifyTabStripChanged(int position, int notificationsCount) {
LinearLayout tabHost = (LinearLayout) tabs.getChildAt(0);
RelativeLayout tabLayout = (RelativeLayout) tabHost.getChildAt(position);
TextView badge = (TextView) tabLayout.findViewById(R.id.badge);
if (notificationsCount > 0) {
badge.setVisibility(View.VISIBLE);
badge.setText(String.valueOf(notificationsCount));
} else {
badge.setVisibility(View.GONE);
}
}
Don't forget, that child views count is starting from 0. If you want to use images, just replace ImageView with TextView badge and change it's image resource instead of text. Enjoy!
You can achieve what you want by forking this lib and change the behaviour of IconTabProvider used there in sample app implemented to use only static resources.
Changes to do to your lib fork to add dynamic icon changes:
In PagerSlidingTabStrip:
Change return type (and name) of getPageIconResId method of IconTabProvider interface
public interface IconTabProvider {
//public int getPageIconResId(int position) becomes
public Bitmap getPageIconBitmap(int position)
}
This causes to update the call to this method in PagerSlidingTabStrip
--
And also to change the method addIconTab from
private void addIconTab(final int position, int resId) {
ImageButton tab = new ImageButton(getContext());
tab.setImageResource(resId);
addTab(position, tab);
}
to
private void addIconTab(final int position, bitmap icon) {
ImageButton tab = new ImageButton(getContext());
tab.setImageBitmap(icon);
addTab(position, tab);
}
Then you need to create an adapter for your tabs bar, here is an example:
public class DynamicIconPagerAdapter extends PagerAdapter implements IconTabProvider {
public HashMap<Integer, Bitmap> mapBetweenPositionAndIcons = new HashMap();
public DynamicIconPagerAdapter () {
super();
}
#Override
public int getCount() {
return mapBetweenPositionAndIcons.size();
}
#Override
public Bitmap getPageIconResId(int position) {
return mapBetweenPositionAndIcons.get(position);
}
#Override
public Object instantiateItem(ViewGroup container, int position) {
// looks a little bit messy here
TextView v = new TextView(getActivity());
v.setBackgroundResource(R.color.background_window);
v.setText("PAGE " + (position + 1));
final int padding = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 16, getResources()
.getDisplayMetrics());
v.setPadding(padding, padding, padding, padding);
v.setGravity(Gravity.CENTER);
container.addView(v, 0);
return v;
}
#Override
public void destroyItem(ViewGroup container, int position, Object view) {
container.removeView((View) view);
}
#Override
public boolean isViewFromObject(View v, Object o) {
return v == ((View) o);
}
}
Finally, when you want to update an icon just change the corresponding bitmap of the map (mapBetweenPositionAndIcons) and call notifyDataSetChanged() on your PagerSlidingTabStrip object.
I havn't tested my solution yet due to a lack of time, but I will as soon as possible! ;)
I'm making use of Viewpager in my application.. when the user swipes left or right, I'll show next or previous image - basically a slideshow (of images) kind of app..
If the user taps on the app, I want to flip a view in ViewPager.. a view behind every single view - user must be able to flip the view when he taps on it.
This is the code,
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
.... <some code> ....
viewPager = (ViewPager) findViewById(R.id.main_viewpager);
ImagePagerAdapter adapter = new ImagePagerAdapter();
viewPager.setAdapter(adapter);
PageListener pageListener = new PageListener();
viewPager.setOnPageChangeListener((OnPageChangeListener) pageListener);
final GestureDetector tapGestureDetector = new GestureDetector(this, new TapGestureListener());
viewPager.setOnTouchListener(new OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
tapGestureDetector.onTouchEvent(event);
return false;
}
});
}
private class TapGestureListener extends GestureDetector.SimpleOnGestureListener{
#Override
public boolean onSingleTapConfirmed(MotionEvent e) {
// HERE I CAPTURED SINGLE TAP.. HOW DO I CHANGE THE VIEW OF VIEWPAGER?
return false;
}
}
I think you should set onTouchEvent to the View inside the page, not to the whole viewpager.
In the ImageViewPagerAdapter, you have
#Override
public Object instantiateItem(ViewGroup container, final int position) {
when create the view, I assume an ImageView, set the onTouchListener to it so you have a reference to the view that can be touched.
For the flipping itself take a look at this example, it's very clear.
EDIT:
here an example I copy pasted from an app I made, I cut off the actual code inside the onclicklistener because it was quite long and not relevant. I used this method because inside istantiateItem() you create the view you want to attach the listener to.
#Override
public Object instantiateItem(ViewGroup container, final int position) {
Context context = MainActivity.this;
Log.e("InstantiateItem",Integer.toString(position));
ImageView imageView = new ImageView(context);
imageView.setImageResource(mImages[position]);
imageView.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// do some stuf when clicked...to see if it works you could try
Log.e("Click on image",Integer.toString(position));
}
});
((ViewPager) container).addView(imageView, 0);
return imageView;
}
Is there a way I can embed a loading progress indicator in a ListActivity or Fragment the same way that I can call setListShown() in a ListFragment? I can use a loading dialog but I would prefer to keep things consistent as I am already using setListShown() in other ListFragments.
Thanks.
I accomplished this by writing a wrapper for the fragment class similar to ListFragment.
public class AsyncFragment extends Fragment {
static final int INTERNAL_PROGRESS_CONTAINER_ID = 0x00ff0001;
static final int INTERNAL_CONTENT_CONTAINER_ID = 0x00ff0002;
View mProgressContainer;
View mContentContainer;
boolean mContentShown = true;
public AsyncFragment() {}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,

// ------------------------------------------------------------------

public void setView(View v) {
FrameLayout lframe = (FrameLayout) getView().findViewById(INTERNAL_CONTENT_CONTAINER_ID);
lframe.addView(v, new FrameLayout.LayoutParams(

}
#Override

}
#Override
public void onDestroyView() {
mContentShown = false;
mProgressContainer = mContentContainer = null;
super.onDestroyView();
}
public void setContentShown(boolean shown) {
setContentShown(shown, true);
}
public void setContentShownNoAnimation(boolean shown) {
setContentShown(shown, false);
}
private void setContentShown(boolean shown, boolean animate) {
mProgressContainer = getView().findViewById(INTERNAL_PROGRESS_CONTAINER_ID);
mContentContainer = getView().findViewById(INTERNAL_CONTENT_CONTAINER_ID);
if (mContentShown == shown) {
return;
}
mContentShown = shown;
if (shown) {

mProgressContainer.startAnimation(AnimationUtils.loadAnimation(

mContentContainer.startAnimation(AnimationUtils.loadAnimation(

} else {
mProgressContainer.clearAnimation();
mContentContainer.clearAnimation();
}
mProgressContainer.setVisibility(View.GONE);
mContentContainer.setVisibility(View.VISIBLE);
} else {
if (animate) {
mProgressContainer.startAnimation(AnimationUtils.loadAnimation(
getActivity(), android.R.anim.fade_in));
mContentContainer.startAnimation(AnimationUtils.loadAnimation(
getActivity(), android.R.anim.fade_out));
} else {
mProgressContainer.clearAnimation();
mContentContainer.clearAnimation();
}
mProgressContainer.setVisibility(View.VISIBLE);
mContentContainer.setVisibility(View.GONE);
}
}
I use this for fragments that I'm populating asynchronously. To use it, do not override onCreateView(). Instead, inflate your view in onStart() and call setView() with it. The fragment will start with a loading spinner. Call setContentShow(true) after you are done populating your view to remove the loading animation and show your content.
In the CustomPagerAdapter of the ViewPager, in instantiateItem() method I'm trying to create an TextView and then for each page set a different text depending on certain condition. Text is read from a pages Cursor. Here is a code:
#Override
public Object instantiateItem(ViewGroup collection, int position) {
sc = new ScrollView(context);
sc.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
sc.setFillViewport(true);
tv = new TextView(context);
if(position < count) {
tv.setText(pages.getString(1));
pages.moveToPosition(position);
}else {
tv.setText("LOCKED");
}
tv.setTag(TAG_PAGE + position);
tv.setGravity(Gravity.CENTER);
tv.setTextColor(Color.BLACK);
tv.setTextSize(30);
sc.addView(tv);
((ViewPager) collection).addView(sc);
return sc;
}
However ViewPager behaves not as expected. The first and the second page have the same text, rest of the pages has a sign "LOCKED" as expected. When I swipe into the 4th page and come back to the first page then the first page consists of the text that suppose to be in the second page. I also tried to use myViewPager.setOffscreenPageLimit(numberOfPages) however it doesn't help.
I found this answer:
"Inside of instantiateItem, the position parameter is the position that is in need of rendering. It is NOT the position of the currently focused item that the user would see. The pages to the left and right of the currently displayed view need to be pre rendered in memory so that the animations to those screens will be smooth. "
It make sense to me but how then can I correctly display the pages content and then update it if desired? Please advise if there is different way to do it with skipping instantiateItem() method that introduce the mess and confusion into the problem. Thank you.
I have solved this problem by using a different implementation:
// Adapter class
private static class MyFragmentPagerAdapter extends FragmentPagerAdapter {
public MyFragmentPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int index) {
return PageFragment.newInstance(pages[index]); // Pages is an array of Strings
}
#Override
public int getCount() {
return numberOfPages;
}
}
// PageFragment class
public class PageFragment extends Fragment {
TextView tv;
public static PageFragment newInstance(String page) {
PageFragment pageFragment = new PageFragment();
Bundle bundle = new Bundle();
bundle.putString("pageContent", page);
pageFragment.setArguments(bundle);
return pageFragment;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment, container, false);
tv = (TextView) view.findViewById(R.id.text_view);
tv.setText(getArguments().getString("pageContent"));
return view;
}
}
You can Create ViewPager Object and then set Listener onthis object.
ViewPager myPager = (ViewPager) findViewById(R.id.yourPagerid);
myPager.setAdapter(adapter);
myPager.setCurrentItem(0);
myPager.setOnPageChangeListener(new OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
//You can change textview word according to current page
switch (position) {
case 0:
break;
case 1:
break;
case 2:
break;
}
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
// Log.d("check","onPageScrolled");
}
#Override
public void onPageScrollStateChanged(int arg0) {
// Log.d("check","onPageScrollStateChanged");
}
});
