I am using cardview with recycler view.But earlier I used the same code to do things without any problems.But now I am using fragments. Now I am getting the distance between the cardviews are greater.
my recycler view adapter
public static class DataObjectHolder extends RecyclerView.ViewHolder implements View.OnClickListener
{
TextView label;
TextView dateTime;
ImageView imageView;
ProgressBar progressBar;
public DataObjectHolder(final View itemView, final Context activity, final ArrayList<DataObject> myDataset) {
super(itemView);
label = (TextView) itemView.findViewById(R.id.textView);
//dateTime = (TextView) itemView.findViewById(R.id.thot);
imageView=(ImageView)itemView.findViewById(R.id.iproductimg);
progressBar=(ProgressBar)itemView.findViewById(R.id.progress);
Log.i(LOG_TAG, "Adding Listener");
itemView.setOnClickListener(this);
}
#Override
public void onClick(View v) {
myClickListenerhi.onItemClick(getLayoutPosition(),v);

public MyRecyclerViewAdapter(Activity context, ArrayList<DataObject> myDataset,MyClickListener myClickListener1) {
mDataset = myDataset;
activityContext=context;
myClickListenerhi=myClickListener1;
}
#Override
public DataObjectHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.cardview, parent, false);
DataObjectHolder dataObjectHolder = new DataObjectHolder(view,activityContext,mDataset);
return dataObjectHolder;
}
#Override
public void onBindViewHolder(final DataObjectHolder holder, int position) {
Context context=null;
holder.label.setText(mDataset.get(position).getmText1());
// holder.dateTime.setText(mDataset.get(position).getmText2());
Drawable placeholder = holder.imageView.getContext().getResources().getDrawable(R.drawable.placeholder);
holder.imageView.setImageDrawable(placeholder);

The error
I solved this by changing Cardview LinearLayout attribute from
android:layout_width="match_parent"
android:layout_height="match_parent"
to
android:layout_width="wrap_content"
android:layout_height="wrap_content"
Edit:
Main problem is that the recyclerviews child layout or item layout rootview attribute is match_parent.
change it attribut to wrap_content
android:layout_width="wrap_content"
android:layout_height="wrap_content"
In this case : in the layout of cardview:
remove :layout_margin="5dp"
add :
margin_top = "3dp"
margin_left = "5dp"
margin_right = "5dp"

I have a recycler inside fragment in view pager.
The problem that it put likes on user accounts in UI randomly but in DB everything is fine.
In logs, I see that random is not influence on BD. So the bug is only in UI part. After the refresh of the list, it can appear again and after that disappear.
I would like to share code but I already don't have an I idea where the problem could be. It might be in adapter/refresh list listener / XML or any other places. Please let me know what part of the code you need and I will provide it. Maybe it is a bug of recycler as itself and I can't fix it.

I am using vector images generated from Android Studio but those images are not displayed in recyclerView.
What should i do? Let me mention that the vector images that i use inside recyclerView are properly displayed if i use them in simple image views.
So in my recyclerview, i have a CARDVIEW which consists of
ImageView, EditText and a button. and when i click the button, it will send the text from EditText to PARSE.com. My problem is that, i cannot link that text to it's ImageView
i want when i open the app, i can see the imageView and at the bottom there will be a description for the image. i want the editText to be dynamic. Can Someone guide me?
