I am sending arraylist from gridviewadapter to the fragment but data its not displayed. the gridview code was working when sending arraylist to an activity, so the problem is with the fragment
this is the grid view adapter
@Override
public View getView(int position, View convertView, ViewGroup parent) {
System.out.println("entering adapter1");
View row = convertView;
final ViewHolder holder;
if (row == null) {
LayoutInflater inflater = LayoutInflater.from(mcontext);
row = inflater.inflate(layoutResourceId, parent, false);
holder = new ViewHolder();
holder.imageTitle = (TextView) row.findViewById(R.id.text);
holder.imageView = (ImageView) row.findViewById(R.id.imageView);
row.setTag(holder);
} else {
holder = (ViewHolder) row.getTag();
}
final Listitem item = getItem(position);
System.out.println("item.getUrl() ");
System.out.println(item.getUrl());
Picasso.with(mcontext).setIndicatorsEnabled(true);
holder.imageTitle.setText(item.getId());
/* Picasso.
with(mcontext).
load(item.getUrl())
.placeholder(R.drawable.logo)
.fit()
.noFade()
.into(holder.imageView)
;*/
//int maxSize = 4 * 1024 * 1024; // 4MiB
//Picasso myNewPicasso = new Picasso.Builder(mcontext).memoryCache(new LruCache(maxSize)).build();
Picasso.with(mcontext)
.load(item.getUrl())
.placeholder(R.drawable.logo)
.fit()
.noFade()
.into(holder.imageView);
holder.imageView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
ArrayList<Listitem> personArrayList = new ArrayList<>();
personArrayList.add(new Listitem(item.getId(), item.getUrl()));
Intent intent = new Intent(mcontext,SingleViewActivity.class);
intent.putExtra("Person_List", personArrayList);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
mcontext.startActivity(intent);
Log.d("OnImageButton", "Clicked");
}
});
return row;
}
static class ViewHolder {
TextView imageTitle;
ImageView imageView;
}
this is the fragment that contain also a view pager
public class SingleViewActivity extends FragmentActivity {
ImageView imageView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_page_view);
DemoCollectionPagerAdapter mDemoCollectionPagerAdapter = new DemoCollectionPagerAdapter( getSupportFragmentManager());
ViewPager mViewPager = (ViewPager) findViewById(R.id.pager);
imageView = (ImageView) findViewById(R.id.funnyimage);
Bundle bundle = getIntent().getExtras();
Log.d("s","singleview");
mViewPager.setAdapter(mDemoCollectionPagerAdapter);
}
/* if (savedInstanceState == null) {
// During initial setup, plug in the details fragment.
MyFragment myrag = new MyFragment();
myrag.setArguments(getIntent().getExtras());
getSupportFragmentManager().beginTransaction().add(android.R.id.content, myrag).commit();
}
*/
// Since this is an object collection, use a FragmentStatePagerAdapter,
// and NOT a FragmentPagerAdapter.
public class DemoCollectionPagerAdapter extends FragmentStatePagerAdapter {
public DemoCollectionPagerAdapter(FragmentManager fm) {
super(fm);
Log.d("s","adapterview");
}
@Override
public Fragment getItem(int i) {
Fragment fragment = new DemoObjectFragment();
Bundle args = new Bundle();
// Our object is just an integer :-P
args.putInt(DemoObjectFragment.ARG_OBJECT, i + 1);
fragment.setArguments(args);
return fragment;
}
@Override
public int getCount() {
return 100;
}
@Override
public CharSequence getPageTitle(int position) {
return "OBJECT " + (position + 1);
}
}
// Instances of this class are fragments representing a single
// object in our collection.
public static class DemoObjectFragment extends Fragment {
public static final String ARG_OBJECT = "object";
ImageView imageView;
int imageResourceId;
int numberSelected;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//change to avoid orientation crash
Log.d("s","fragview");
}
public static Fragment newInstance(Context context,ArrayList<Listitem> personArrayList, int numberSelected) {
DemoObjectFragment f = new DemoObjectFragment();
Bundle args= new Bundle();
args.putParcelableArrayList("Person_List", personArrayList);
//args.putInt("",imageResourceId);
f.setArguments(args);
return f;
}
@Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState) {
// The last two arguments ensure LayoutParams are inflated
// properly.
View rootView = inflater.inflate(
R.layout.fragment_collection_object, container, false);
// Bundle args = getArguments();
// ((TextView) rootView.findViewById(R.id.text1)).setText(Integer.toString(args.getInt(ARG_OBJECT)));
Bundle args= new Bundle();

System.out.print(personArrayList);
System.out.print("here1");
if (personArrayList != null && !personArrayList.isEmpty()) {
for (Listitem person : personArrayList) {
Picasso.
with(getActivity()).
load(person.url)
.placeholder(R.drawable.logo)
.fit()
.noFade()
.into(imageView);
Log.i("PersonsActivity",String.valueOf(person.url));
}
}
return rootView;
}
}
}
A bit explanation of what I am doing
In my main activity I have a grid view of image, when I click on one image , I get the single image-clicked on a new activity. I used that with parcelable arraylist that send data from gridview to singleview acitivity. it was working for the activity. but when I implemented the viewpager and the fragment and fragment adapter nothing is showing I dont know why,
this is my logcat , as you notice its not proceeding to the rest,fragview is a log print added in my code.

this is part of the fragment code in Singleviewactivity.java
public static class DemoObjectFragment extends Fragment {
public static final String ARG_OBJECT = "object";
ImageView imageView;
int imageResourceId;
int numberSelected;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//change to avoid orientation crash
Log.d("s","fragview");
}
public static Fragment newInstance(Context context,ArrayList<Listitem> personArrayList, int numberSelected) {
DemoObjectFragment f = new DemoObjectFragment();
Bundle args= new Bundle();
args.putParcelableArrayList("Person_List", personArrayList);
//args.putInt("",imageResourceId);
f.setArguments(args);
return f;
}
@Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState) {
// The last two arguments ensure LayoutParams are inflated
// properly.
View rootView = inflater.inflate(
R.layout.fragment_collection_object, container, false);
// Bundle args = getArguments();
// ((TextView) rootView.findViewById(R.id.text1)).setText(Integer.toString(args.getInt(ARG_OBJECT)));
Bundle args= new Bundle();
ArrayList<Listitem> personArrayList = args.getParcelableArrayList("Person_List");
System.out.print(personArrayList);
System.out.print("here1");
if (personArrayList != null && !personArrayList.isEmpty()) {
for (Listitem person : personArrayList) {
Picasso.
with(getActivity()).
load(person.url)
.placeholder(R.drawable.logo)
.fit()
.noFade()
.into(imageView);
Log.i("PersonsActivity",String.valueOf(person.url));
}
}
return rootView;
}
}
}
