I have a recyclerview when it displayed for the first time the child's layout are not displayed properly:
but when i scroll to bottom and come back to the top it's good :
I have the same problem when i change the layout for a larger.
This is my Adapter class (don't take in consideration the diffents type,this is not the source of the bug because the bug exist too when i have one ViewHolder type)
private class Adapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private static final int TYPE_ALERTS = 0 ;
private static final int TYPE_MOST_VIEWED = 1 ;
#Override
public RecyclerView.ViewHolder onCreateViewHolder (final ViewGroup parent, int viewType) {
if (viewType == TYPE_ALERTS){
View itemLayoutView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.layout_item_alerts_home_home, null);
ViewHolderAlerts viewHolderAlerts = new ViewHolderAlerts(itemLayoutView);
itemLayoutView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick (View v) {
Intent intent = new Intent(activity, Activity_UpdateAlert.class);
intent.putExtra("alert", (AlertObj)listAllProducts.get(recyclerView.getChildAdapterPosition(v)));
startActivity(intent);
}
});
return viewHolderAlerts;
}else {
View itemLayoutView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.layout_item_product_grid__list_products_by_category, null);
ViewHolder_Product_CatSearch viewHolder_product_catSearch = new ViewHolder_Product_CatSearch(itemLayoutView);
itemLayoutView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick (View v) {
Intent intent = new Intent(activity, Activity_ProductDetails.class);
intent.putExtra("product", (Product)listAllProducts.get(recyclerView.getChildAdapterPosition(v)));
startActivity(intent);
}
});
return viewHolder_product_catSearch ;
}
}
#Override
public void onBindViewHolder (RecyclerView.ViewHolder holder, int position) {
if (getItemViewType(position) == TYPE_ALERTS){
((ViewHolderAlerts)holder).textViewTitle.setText(((AlertObj)listAllProducts.get(position)).product.name);

Want to add margin to gridview in the following manner.
Left margin for 2,4, 2,9, 12,14,..
Right margin for 3,5, 8,10, 13,15,..
Here is my code snippet which I tried to set margin to 2x2 items in grid view...
i.e positions - ..,2,3,4,5,..,7,8,9,10,..,12,13,14,15,..,17,18,19,20,.. like wise.
for 2,3,4,5 & 12,13,14,15,.. Getting the expected output. but my case failed for 7,8,9,10 & 17,18,19,20 series.
Help me to solve this. Confused to solve this mathematical puzzle.

Please help
i think that the position of category in popup menu will be the same as section value of the second recyclerView if you get the position of clicked item in your activity by listening on item's click you can scroll the recyclerView using the LayoutManager.
recyclerView.getLayoutManager().scrollToPosition(youPositionInTheAdapter).
I have an awards section where I load data from my server.
I'm pulling 8 by 8 awards from server and loading them in my ListView. Awards can be sold and in my adapter I have a checker where if quantity < 1 there will be a bar over Image that will notify user that award is sold.
There is lazy load where user can swipe to load more details by increasing index, so server can determine which 8 awards should he return. 1 for first 8, 2 for second 8 etc.
Problem is when I scroll to first sold award, ListView gets weird and all awards get that sold bar over their images. This is the code from activity:
public class AwardListFragment extends Fragment { int offset = 0;
int size = 8;
private int ID;
private boolean _isAwardsLoaded = false;
private SwipyRefreshLayout swipyRefreshLayout;
private ProgressDialog progressBar;
private ArrayList<Awards> listAwards;
ListView awardlist;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.rewards_section, parent, false);
awardlist = (ListView) rootView.findViewById(R.id.awardlist);
awardlist.setItemsCanFocus(true);
listAwards = new ArrayList<>();
swipyRefreshLayout = (SwipyRefreshLayout) rootView.findViewById(R.id.swipe_section_swipe);
awardlist.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent intent = new Intent(getActivity(), AwardDetailsScreen.class);
ID = listAwards.get(position).getId();
Bundle bundle = new Bundle();
bundle.putInt("ID", ID);
intent.putExtras(bundle);
startActivity(intent);
}
});
return rootView;
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
}
public void showlist() {
progressBar = new ProgressDialog(getActivity());
progressBar.setMessage("Pls Wait...");
progressBar.show();
final int firstitemposition = 0;
final int currentposition = awardlist.getFirstVisiblePosition();
NetworkSDK.getInstance().getAwards(size, offset, new Callback<List<Awards>>() {
#Override
public void onResponse(Call<List<Awards>> call, Response<List<Awards>> response) {
if (response.code() == 401) {
Intent intent = new Intent(getContext(), MainPreLogin.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
SharedData.getInstance().removeString("token");
} else {
if (response.isSuccess()) {
if (response.body().size() == 0) {
Toast.makeText(getContext(), "All awards loaded", Toast.LENGTH_SHORT).show();
progressBar.setCancelable(false);
progressBar.dismiss();
} else
for (int i = 0; i < response.body().size(); i++)
listAwards.add(response.body().get(i));
AwardsAdapter awardsAdapter = new AwardsAdapter(listAwards);
awardlist.setAdapter(awardsAdapter);
awardsAdapter.notifyDataSetChanged();
awardlist.setSelectionFromTop(currentposition, firstitemposition);
}
progressBar.setCancelable(false);
progressBar.dismiss();
}
}
#Override
public void onFailure(Call<List<Awards>> call, Throwable t) {
Toast.makeText(getContext(), R.string.errorNoconnection, Toast.LENGTH_LONG).show();
progressBar.dismiss();
}
});
}

super.setUserVisibleHint(isVisibleToUser);
if (isVisibleToUser && !_isAwardsLoaded) {
swipyRefreshLayout.setOnRefreshListener(new SwipyRefreshLayout.OnRefreshListener() {

if (direction == SwipyRefreshLayoutDirection.BOTTOM) {
offset++;
swipyRefreshLayout.setRefreshing(false);
showlist();
}
}
showlist();
});
}
}
}
This is my adapter.
public class AwardsAdapter extends BaseAdapter {
ArrayList<Awards> awards;
public AwardsAdapter(ArrayList<Awards> awards) {
this.awards = awards;
}

// clear the data

private class ViewHolder {
TextView name;
TextView price;
TextView points;
ImageView picture;
ImageView checker;
public ViewHolder(View view) {
this.name = (TextView) view.findViewById(R.id.award_name);
this.price = (TextView) view.findViewById(R.id.award_price);
this.picture = (ImageView) view.findViewById(R.id.award_picture);
this.points = (TextView) view.findViewById(R.id.award_points);
this.checker=(ImageView)view.findViewById(R.id.checker);
}
}
}
In your adapter's getView(), you have this piece of code:
if (awards.getQuantity()<1)
Picasso.with(view.getContext()).load(R.drawable.sold).into(viewHolder.checker);
else
if (awards.getIsVip())
Picasso.with(view.getContext()).load(R.drawable.vip).into(viewHolder.checker);
Change it to something like this (it depends on how you want to show/hide your view. As it stands, you're not handling the case where you need to hide it!):
if (awards.getQuantity()<1) {
Picasso.with(view.getContext()).load(R.drawable.sold).into(viewHolder.checker);
}
else {
// hide viewHolder.checker here
}
if (awards.getIsVip()) {
Picasso.with(view.getContext()).load(R.drawable.vip).into(viewHolder.checker);
}
Note: As a general piece of advice, always use curly brackets to avoid such bugs and confusion.

your dbUsersList is not updating. please check your user object in dbUsersList after notify data set change.
What ended up being the problem is that I had passed in the followingList, so I never re-called to grab the new following from the db on update. The update was happening I just had to re-grab the followingList from the db to have an updated list to check against like so in a new method that was passing the list back to the contains method.
db.grabFollowersList();
This is Adapter!
public class CategoryAdapter extends RecyclerView.Adapter<CategoryAdapter.CategoryAdapterObjectHolder> {
private static String LOG_TAG = "CategoryAdapter";

private static MyClickListener myClickListener;
public static class CategoryAdapterObjectHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

public CategoryAdapterObjectHolder(View itemView) {
super(itemView);
mTextTitle = (TextView) itemView.findViewById(R.id.text_menu);
DebugTool.logD(LOG_TAG + "Adding Listener");
itemView.setOnClickListener(this);
}
#Override
public void onClick(View v) {
myClickListener.onItemClick(getPosition(), v);
}
}
public void setOnItemClickListener(MyClickListener myClickListener) {
this.myClickListener = myClickListener;

This is OnItemClick
#Override

TextView mTextItem = (TextView) v.findViewById(R.id.text_menu);
// mTextItem.setTextColor(getResources().getColor(R.color.color_text_white));
if (position == 0) {
Utils.showToast(getContext(), "POSITION 0");
} else if (position == 1) {
Utils.showToast(getContext(), "POSITION 1");
} else if (position == 2) {
Utils.showToast(getContext(), "POSITION 2");
} else if (position == 3) {

I click position == 3 :
Text colour of position == 3 change to Dark and position different back colour white.
Please. Help me!
1- Create variable currentPosition default = -1 in adapter
private int currentPosition =-1;
2- onBindViewHolder set default text color Black and when user click view:
notifyItemChanged(currentPosition) - update default view for old view(reload)
Set text color White.
#Override
public void onBindViewHolder(final DataObjectHolder holder, final int position) {
ViewGroup.LayoutParams layoutParams = holder.view.getLayoutParams();
holder.view.setLayoutParams(layoutParams);
final String text = mDataSet.get(position);
holder.textView.setTextColor(Color.BLACK);
holder.textView.setText(text);
holder.view.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(currentPosition>=0) {
notifyItemChanged(currentPosition);
}
holder.textView.setTextColor(Color.WHITE);
currentPosition=position;
}
});
}
I'm not sure I understand fully what you are trying to achieve but if you are trying to change the colour of your TextField's text and assuming your OnItemClickListener is being called:
Create a field that will hold all of your TextViews.
private TextView[] textViews;
In your onCreateView method.
textViews = new TextView[4];
textViews[0] = (TextView) view.findViewById(R.id.textViewOne);
textViews[1] = (TextView) view.findViewById(R.id.textViewTwo);
textViews[2] = (TextView) view.findViewById(R.id.textViewThree);
textViews[3] = (TextView) view.findViewById(R.id.textViewFour);
Now in your OnItemClickListener
#Override
public void onResume() {
super.onResume();
((CategoryAdapter) adapter).setOnItemClickListener(
new CategoryAdapter.MyClickListener() {
#Override
public void onItemClick(int position, View v) {
Color white = getResources().getColor( R.color.color_text_white );
Color dark = getResources().getColor( R.color.color_text_dark );
for ( int i = 0; i < textViews.length; i++ ) {
TextView textView = textViews[i];
if ( i == position )
textView.setTextColor( dark );
else
textView.setTextColor( white );
}
}
});
}
