viewpager scrollview not working android

I'm integrating ViewPager and ScrollView on android but it doesn't seem to work. The ViewPager scroll works just fine but the ScrollView does not work at all on all the solutions I've tried. Below is my MainActivity class and xml layout.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.navigation_drawer);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
hostDescription = (TextView) findViewById(R.id.host_description);
hostDescription.setTypeface(quickSandRegular);
hostDescription.setTextColor(Color.BLACK);
scrollView = (ScrollView) findViewById(R.id.scroll);
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
View header=navigationView.getHeaderView(0);
ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);
ImageAdapter adapter = new ImageAdapter();
viewPager.setAdapter(adapter);
// set navigation font
Menu m = navigationView.getMenu();
for (int i=0;i<m.size();i++) {
MenuItem mi = m.getItem(i);
// apply font to subment
SubMenu subMenu = mi.getSubMenu();
if (subMenu!=null && subMenu.size() >0 ) {
for (int j=0; j <subMenu.size();j++) {
MenuItem subMenuItem = subMenu.getItem(j);
applyFontToMenuItem(subMenuItem);
}
}
applyFontToMenuItem(mi);
}
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
}

ImageAdapter
class ImageAdapter extends PagerAdapter {
#Override
public int getCount() {
return IMAGES.length;
}
#Override
public boolean isViewFromObject(View view, Object object) {
return view == ((ImageView) object);
}
#Override
public Object instantiateItem(ViewGroup container, int position) {
ImageView imageView = new ImageView(getApplicationContext());
imageView.setImageResource(IMAGES[position]);
((ViewPager) container).addView(imageView, 0);
return imageView;
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
((ViewPager) container).removeView((ImageView) object);
}
}

You need to implement ViewPager.OnPageChangeListener and write your logic in onPageScrollStateChanged
#Override
public void onPageScrollStateChanged(int state) {
ScrollView.requestDisallowInterceptTouchEvent(!(!lastPage && state == ViewPager.SCROLL_STATE_IDLE));
}
You need to write logic to find if you are on last page or not which is simple.

Solved the problem by customizing layout_height of the ViewPager. Below is the code:
<android.support.v4.view.ViewPager
android:id="#+id/view_pager2"
android:layout_width="match_parent"
android:layout_height="300dp"
android:paddingLeft="20dp"
android:paddingRight="20dp"/>
ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);
ImageAdapter adapter = new ImageAdapter();
viewPager.setAdapter(adapter);
viewPager.setClipToPadding(false);
viewPager.setPadding(70, 0, 70, 0);
class ImageAdapter extends PagerAdapter {
#Override
public int getCount() {
return IMAGES.length;
}
#Override
public boolean isViewFromObject(View view, Object object) {
return view == ((ImageView) object);
}
#Override
public Object instantiateItem(ViewGroup container, int position) {
ImageView imageView = new ImageView(getApplicationContext());
imageView.setImageResource(IMAGES[position]);
((ViewPager) container).addView(imageView, 0);
return imageView;
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
((ViewPager) container).removeView((ImageView) object);
}
#Override
public void setPrimaryItem(ViewGroup container, int position, Object object) {
setPrimaryItem((View) container, position, object);
// lastPage = IMAGES[position]==object;
}
}

TabHost Viewpager listview doesn't scroll

Tabhost + viewpager horizontal scroll. if the fragment is empty or contains a textview, it works, but if the fragment contains a list view,, fragment it's doesn't scroll horizontal !!
if I try to scroll from the textview it works or if the fragment is empty it's work , but from the listview no, noted that the textview its width and height are wrap_content while those in the listview are match_parent
frgament 2 (it contains the fragment of tabhost )

How to create hover text on image slider android?

I have an image slider with the bottom code:
public class MainActivity extends Activity {
private class ImagePagerAdapter extends PagerAdapter {
private final int[] mImages = new int[] {
R.drawable.chiang_mai,
R.drawable.himeji,
R.drawable.petronas_twin_tower,
R.drawable.ulm
};
#Override
public void destroyItem(final ViewGroup container, final int position, final Object object) {
((ViewPager) container).removeView((ImageView) object);
}
#Override
public int getCount() {
return this.mImages.length;
}
#Override
public Object instantiateItem(final ViewGroup container, final int position) {
final Context context = MainActivity.this;
final ImageView imageView = new ImageView(context);
final int padding = context.getResources().getDimensionPixelSize(
R.dimen.padding_medium);
imageView.setPadding(padding, padding, padding, padding);
imageView.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
imageView.setImageResource(this.mImages[position]);
((ViewPager) container).addView(imageView, 0);
return imageView;
}
#Override
public boolean isViewFromObject(final View view, final Object object) {
return view == ((ImageView) object);
}
}
#Override
public void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);
final ImagePagerAdapter adapter = new ImagePagerAdapter();
viewPager.setAdapter(adapter);
final CirclePageIndicator circleIndicator = (CirclePageIndicator) findViewById(R.id.indicator);
circleIndicator.setViewPager(viewPager);
final TextView tvText = (TextView) findViewById(R.id.text);
tvText.setText(getResources().getString(R.string.bodyText));
}
}
And this is the XML code:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<android.support.v4.view.ViewPager
android:id="#+id/view_pager"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
/>
<com.viewpagerindicator.CirclePageIndicator
android:id="#+id/indicator"
android:padding="10dip"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
/>
<TextView
android:id="#+id/text"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
So I need to set a text Hover on the Viewpager so that when I swipe it, it will show up for a specific picture. How can I create a hover text on this image slider while making it run automatically for some specific time, and after a swipe show a hover text.

Have you just one XML Layout? If you've two it makes it quite alot easier to work with.
So this layout below is where the actual image slider will be place on the Home Fragment in this case.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.****.****.HomeFragment"
android:background="#000000"
>
<android.support.v4.view.ViewPager
android:id="#+id/view_pager"
android:layout_width="fill_parent"
android:layout_height="204dp"
android:scaleType="centerCrop"
></android.support.v4.view.ViewPager>
Secondly, this XML Layout below is the Layout for the ViewPager itself. As you can see it is made up of an ImageView and a TextView. With the TextView placed on top of the ImageView.
Hope this helps a bit.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/image_view"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:scaleType="centerCrop"
/>
<TextView
android:id="#+id/myImageViewText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/image_view"

ScrollView inside ViewPager

Please Help me.
I searched everywhere how I can make a ScrollView inside a ViewPager but it was not successfully. The hole layout of the ViewPager should be scrollable.
Important: I only want a ScrollView in the vertical.
Already now I want to say thanks for the answers!

maybe you're just not scrolling correctly - an emulator doesn't really have a touch screen. You have to touch and hold part of it while panning with another finger

Fragment crashing on grid initialization

When I switch to the tab with this fragment, it always crashes. The logcat seems to say that it crashes on `mGrid = (GridView) (getView().findViewById(R.id.gridViewRed));
Any idea why?
RedScorerFragment.java
public class RedScorerFragment extends SherlockFragment {
LayoutInflater infl;
GridView mGrid;
#Override
public void onCreate(Bundle savedInstanceState){
mGrid = (GridView) (getView().findViewById(R.id.gridViewRed));
mGrid.setOnTouchListener(new OnTouchListener(){
#Override
public boolean onTouch(View v, MotionEvent event){
if(event.getAction() == MotionEvent.ACTION_MOVE)
return true;
return false;
}
});
mGrid.setAdapter(new ImageAdapter(getActivity()));
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
infl = inflater;
return inflater.inflate(R.layout.fragment_score_red, container, false);
}

You need to rethink where you're finding your views. This is because onCreate() is called before onCreateView()
So you should move
mGrid = (GridView) (getView().findViewById(R.id.gridViewRed));
mGrid.setOnTouchListener(new OnTouchListener(){
#Override
public boolean onTouch(View v, MotionEvent event){
if(event.getAction() == MotionEvent.ACTION_MOVE)
return true;
return false;
}
});
mGrid.setAdapter(new ImageAdapter(getActivity()));
to onCreateView() This means that you need to not return the inflation, but instead work with it,
So your onCreateView() should be something like:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
infl = inflater;
View mView = inflater.inflate(R.layout.fragment_score_red, container, false);
mGrid = (GridView) (mView.findViewById(R.id.gridViewRed));
//rest of code above
return mView;
}
