Any code or working example will be much appreciated.
Thank you in advance.

Activity goes here:
in OnCreate i am calling async task to get the image/record's absolute paths from server,and adding those to list as of you are seeing "bitmaps" and "bitmapUrl" on post execute im adding the below code
ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);
adapter = new download_data_adapter(context,bitmaps,bitmapUrl);
viewPager.setAdapter(adapter);

the main.xml can be
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<RelativeLayout
android:id="#+id/wrapper1"
android:layout_width="match_parent"
android:layout_height="#dimen/titlebarsize"
android:background="#color/red">
<SeekBar
android:id="#+id/progressrecord"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:background="#drawable/violetborderbox"
android:thumb="#drawable/playbtn"
android:progressDrawable="#drawable/seekbar_progress"
android:paddingLeft="35dp"
android:paddingRight="35dp"/>
</RelativeLayout>
<RelativeLayout
android:id="#+id/wrapper2"
android:layout_below="#+id/wrapper1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/violetbg"
android:orientation="vertical"
>
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_marginBottom="200dp"
app:matchChildWidth="#+id/vg_cover"
/>
</RelativeLayout>
Create an xml with the following code
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="2"
android:orientation="horizontal" >
<ImageView
android:id="#+id/imageone"
android:layout_height="match_parent"
android:layout_width="0dp"
android:layout_weight="1"
/>
</LinearLayout>
and inflate this inside your adapter class
public class ViewPagerAdapter extends PagerAdapter {
// Declare Variables
Context context;
int[] flagone;
LayoutInflater inflater;
public ViewPagerAdapter(Context context,int[] flagsone) {
this.context = context;
this.flagone = flagsone;
}
#Override
public int getCount() {
return flag.length;
}
#Override
public boolean isViewFromObject(View view, Object object) {
return view == ((RelativeLayout) object);
}
#Override
public Object instantiateItem(ViewGroup container, int position) {
// Declare Variables
ImageView imgone;
Button button;
inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View itemView = inflater.inflate(R.layout.viewpager_image, container,
false);
// Capture position and set to the TextViews
// Locate the ImageView in viewpager_item.xml
imgone = (ImageView) itemView.findViewById(R.id.imageone);
// Capture position and set to the ImageView
imgone.setImageResource(flagone[position]);
// Add viewpager_item.xml to ViewPager
((ViewPager) container).addView(itemView);
return itemView;
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
// Remove viewpager_item.xml from ViewPager
((ViewPager) container).removeView((RelativeLayout) object);
}
}
and in activity
onCreate(){
int imagelist1={R.drawable.image1};
int imagelist2={R.drawable.image2};
ViewPagerAdapter adapter = new ViewPagerAdapter(mContext, imagelist1,imaglist2);
// Binds the Adapter to the ViewPager
myViewPager.setAdapter(adapter);
viewPager.setOnPageChangeListener(new OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
// TODO Auto-generated method stub
//System.out.println("new page selected"+position);

UltimateRecycleView : SetLoadMoreView is Not Working

I am currently working with Android and UltimateRecycleView. I manage to make the ultimaterecycleview working, but when I tried to use the load more functionality, the bottom progress bar is not showing (although the data is loaded). Anyone has experienced this problem? Can you please help me to find out what is wrong?
Here is the code :
--- Adapter ---
public class ListPendingAdapter extends UltimateViewAdapter<ListPendingAdapter.PendingViewHolder> {
private Context context;

You need to put your music to assets directory (ie. create subfolder titled 'sounds') and then list the contents of it by method:
myContext.getAssets().list(”sounds");
Then you have to attach the asset to MediaPlayer object:
mediaPlayer.setDataSource(myContext.getAssets().openFd(soundPathInAssets));
You should also see this thread (because the bit of code I presented to you would play whole directory): Play audio file from the assets directory
EDIT: Code from example project (in case of deleting file on my dropbox):
MainActivity.java
public class MainActivity extends Activity {
MediaPlayer mMediaPlayer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final ListView list = (ListView) findViewById(R.id.listView1);
mMediaPlayer = new MediaPlayer();
Button playPause = (Button) findViewById(R.id.play);
playPause.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if(mControl.isPlaying()){
mControl.pause();
} else {
mControl.start();
}
}
});

GallaryView change Images on button Click a

Currently I am working with GalleryView and changing images that is working perfectly fine.
But I want to disable swipe of GalleryView and change the loaded images on button click.
How can i achieve this functionality.
My current Class is As Follow
public class PopUpWindow extends Activity {
TextView closebtn;
Integer[] pics = {
R.drawable.account_icon,
R.drawable.coffee_icon,
R.drawable.help_icon,
R.drawable.menu_icon,
};
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setUpDialogProperties();
this.setFinishOnTouchOutside(false);
setContentView(R.layout.pop_up_dialog);
fetchUI();
}
private void fetchUI(){
closebtn = (TextView)findViewById(R.id.okBtn);
closeDialog();
Gallery ga = (Gallery)findViewById(R.id.Gallery01);
ga.setAdapter(new ImageAdapter(this));
ga.setUnselectedAlpha(0.0f);
}
private void closeDialog(){
closebtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
finish();
}
});
}
private void setUpDialogProperties() {
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setBackgroundDrawableResource(android.R.color.transparent);
android.view.WindowManager.LayoutParams lp = getWindow()
.getAttributes();
lp.gravity = Gravity.BOTTOM;
getWindow().setAttributes(lp);
}
public class ImageAdapter extends BaseAdapter {
private Context ctx;
int imageBackground;
public ImageAdapter(Context c) {
ctx = c;
TypedArray ta = obtainStyledAttributes(R.styleable.Gallery1);
imageBackground = ta.getResourceId(R.styleable.Gallery1_android_galleryItemBackground, 1);
ta.recycle();
}
#Override
public int getCount() {
return pics.length;
}
#Override
public Object getItem(int arg0) {
return arg0;
}
#Override
public long getItemId(int arg0) {
return arg0;
}
#Override
public View getView(int arg0, View arg1, ViewGroup arg2) {
ImageView iv = new ImageView(ctx);
iv.setImageResource(pics[arg0]);
iv.setScaleType(ImageView.ScaleType.FIT_CENTER);
iv.setLayoutParams(new Gallery.LayoutParams(150,150));
iv.setBackgroundResource(imageBackground);
return iv;
}
}
Thanks in advance

case R.id.leftButton:
int position = mGallery.getSelectedItemPosition() - 1;
if (position < 0)
return;
mGallery.setSelection(position);
break;
case R.id.rightButton:
position = mGallery.getSelectedItemPosition() + 1;
if (position >= mGallery.getCount())
return;
mGallery.setSelection(position);
break;
I will setup the onclick for your next and previous button

Infinite scrolling of listview in android

Now i should implement infinite scrolling to listview, for this i had found one easiest code that is
#Override
public void onScroll(AbsListView view, int firstVisibleItem,
int visibleItemCount, int totalItemCount) {
//leave this empty
}
#Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
if (scrollState == SCROLL_STATE_IDLE) {
if (listView.getLastVisiblePosition() >= listView.getCount() - threshold) {
currentPage++;
//load more list items:
loadElements(currentPage);
}
}
}
but now i dont know what to include in the place if loadElements(current Page)

Here is an example code for you. this list scrolls infinite and using thread, it scrolls automatically. (pauses for while and coninues ...)
When you touch the list, list scrolling pauses and when you release it continues to automatic scroll.
If you touch under 100 miliseconds then it will considered item on click.
You can also scroll down or up, it will eventually continue to auto scrolling.
Come to think of it, it has turn into web like list. shame. :(

How to refer to activity element from viewpager

I try to write an app, that is using slide effect for activities and found that ViewPager from Compatibility Package is what I need. I successfully made the slide, it works in the way i want, but my problem is that I am not able to refer to the elements in my Activity.
This is my main.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
MainActivity.java:
public class MainActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
MyPagerAdapter adapter = new MyPagerAdapter();
ViewPager myPager = (ViewPager) findViewById(R.id.pager);
myPager.setAdapter(adapter);
myPager.setCurrentItem(0);
if (Fibonacci.getInstance().number != 0)
displayResults();
ImageButton btnCalculate = (ImageButton) findViewById(R.id.btnCalculateDark);
btnCalculate.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
// do button click
}
});
}
private class MyPagerAdapter extends PagerAdapter {
public int getCount() {
return 2;
}
public Object instantiateItem(View collection, int position) {
LayoutInflater inflater = (LayoutInflater) collection.getContext()
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
int resId = 0;
switch (position) {
case 0:
resId = R.layout.activity_dark;
break;
case 1:
resId = R.layout.activity_pale;
break;
}
View view = inflater.inflate(resId, null);
((ViewPager) collection).addView(view, 0);
return view;
}
#Override
public void destroyItem(View arg0, int arg1, Object arg2) {
((ViewPager) arg0).removeView((View) arg2);
}
#Override
public boolean isViewFromObject(View arg0, Object arg1) {
return arg0 == ((View) arg1);
}
#Override
public Parcelable saveState() {
return null;
}
}
}
My problem is that I receive NullPointerEception for the following line:
ImageButton btnCalculate = (ImageButton) findViewById(R.id.btnCalculateDark);
I know it's because in setContentView I set up main.xml, and I want to refer to an element in activity_dark.xml or activity_pale.xml. Unfortunately i am not able to figure out how to refer to the element. Any hints would be appreciated! Thank you!

You should better use Fragments for this
http://developer.android.com/guide/components/fragments.html
but if you want do it like this, then try to set listener after page changed:
myPager.setOnPageChangeListener(new OnPageChangeListener(){
#Override
public void onPageScrollStateChanged(int arg0) {
// TODO Auto-generated method stub
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
// TODO Auto-generated method stub
}
#Override
public void onPageSelected(int arg0) {
ImageButton btnCalculate = (ImageButton) findViewById(R.id.btnCalculateDark);
btnCalculate.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
// do button click
}
});
}
});
