I have a fragment with a foldingcell view
here is the mainfragment -
public class FriendFragmentMain extends Fragment {
private static final String TAG = FriendFragmentMain.class.getSimpleName();

friendsListView = (ListView) getActivity().findViewById(R.id.friend_super_list);
friendsItems = new ArrayList<>();
friendsCellListAdapter = new FriendsCellListAdapter(mActivity, friendsItems);
friendsListView.setAdapter(friendsCellListAdapter);
friendsListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int pos, long l) {
((FoldingCell) view).toggle(false);
friendsCellListAdapter.registerToggle(pos);
}
});

now when i run it it throws -
Attempt to invoke virtual method 'void android.widget.ListView.setAdapter(android.widget.ListAdapter)' on a null object reference
at com.evolustudios.askin.askin.src.fragments.FriendFragmentMain.onCreateView(FriendFragmentMain.java:60)
this error. i am unable to find out why its throwing a null object? can anyone throw a light on why its showing null object.

ViewPager Activity change content when slide

I've been looking around but I can't figure out how I can fixed this issue.
I'm using the #Dave Morrissey's Subsampling Zoom Image View, is a great library and it works perfect, but I want to do a few changes.
For each image that the user will slide I want show the specific description.
So it will be:
Pic1 |Pic2 |Pic3
DescriptionPic1 |DescriptionPic2 |DescriptionPic3
When I open it I can see the picture with below the right description but when I slide left(or right) I can see always the description of the item after.
Happens because the method getItem() get called twice to make the slider more smooth.
The problem is that I want show the right content(description) below each picture.
How can I show the content perfectly when the user slide the pics?
Any help is really appreciate.
Thanks guys

you should add image into Map or Array For Reloading:
#Override
public void fill(final Picture picture, int pos, Object... objects) {
image=(ImageView) view.findViewById(R.id.img_galleryadapter_image);
caption=(TextView) view.findViewById(R.id.txt_galleryadapter_caption);
if(bitmapMap.containsKey(picture.imageUrl)){
image.setImageBitmap(bitmapMap.get(picture.imageUrl));
}else {
image.setImageDrawable(context.getResources().getDrawable(R.drawable.ic_hourglass_empty_black_48dp));
Picasso.with(context).load(picture.imageUrl).memoryPolicy(MemoryPolicy.NO_CACHE).skipMemoryCache().into(new Target() {
#Override
public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom loadedFrom) {
image.setImageBitmap(bitmap);
bitmapMap.put(picture.imageUrl, bitmap);
}
#Override
public void onBitmapFailed(Drawable drawable) {}
#Override
public void onPrepareLoad(Drawable drawable) {}
});
}
caption.setText(picture.caption);
}
add to a map:
public static Map<String,Bitmap> bitmapMap=new LinkedHashMap<>();

edit your layout in the xml file to put image then below it a textview using RelativeLayoutor once ur image and its description is aligned its upto ur java codes

After struggling and reading so many different solutions I fixed by myself the issue.
I wanted share with you my solutions maybe can help someone else.
Feel free to ask me everything about it.

Thanks again!

While your RelativeLayout(the one just before the ListView) have match_parent as height, it will take the remaining space of the window... so there is no place for your ListView to be shown.

Try this..
Give id to the above Relative layout and use the same below.
<ListView
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1"
android:orientation="vertical"
android:layout_below="#id/"
android:id="#+id/list_cart_view">
</ListView>

/** Adapter Class */
public class Adapter1 extends BaseAdapter {
ImageView imgImage = null,imgUnlike[] = null, imgLike[] = null,imgComments[] = null, imgShare[] = null;
TextView txtId = null,txtLikeUnlike[] = null, txtComments[] = null;
public ArrayList<HashMap<String, String>> arr = null;
Context context = null;
LayoutInflater layoutInflater = null;
HashMap<String, String> getData = new HashMap<String, String>();
public Adapter1(Context context,
ArrayList<HashMap<String, String>> arr) {
this.context = context;
this.arr = arr;
layoutInflater = LayoutInflater.from(context);
this.imgUnlike = new ImageView[arr.size()];
this.imgLike = new ImageView[arr.size()];
this.imgComments = new ImageView[arr.size()];
this.imgShare = new ImageView[arr.size()];
this.txtLikeUnlike = new TextView[arr.size()];
this.txtComments = new TextView[arr.size()];
}
#Override

return arr.size();
}
#Override

return arr.get(position);
}

return position;
}
#SuppressLint("InflateParams")
#Override
public View getView(final int position, View convertView,
ViewGroup parent) {
View row = null;
if (convertView == null) {
LayoutInflater inflater = ((Activity) context)
.getLayoutInflater();
row = inflater.inflate(R.layout.list_item, parent,
false);
} else {
row = convertView;
}
/** Initialize Widgets */
/** Imageview */
imgImage = (ImageView) row
.findViewById(R.id.imgImage);

getData = arr.get(position);
txtId.setText(getData.get(Fragment1.TAG_ID));
imgUnlike[position]
