I use navigationview. I want to use two icons in navigation view. Currently, when I use .seticon, it changes 2 icons. I want to define icons in two icons separately. I want to define separate icons for navIconNew and navIcon. How can we do that?
Navigation Adapter
public class NavigationAdapter extends RecyclerView.Adapter<NavigationAdapter.ViewHolder> {
Context context;
ArrayList<NavigationDataModel> arrayList = new ArrayList<>();
public NavigationAdapter(Context context, ArrayList<NavigationDataModel> arrayList) {
this.context = context;
this.arrayList = arrayList;
}
#NonNull
#Override
public ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(context).inflate(R.layout.navigationrecyclerview_adapter11, parent, false);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull ViewHolder holder, int position) {
holder.navIcon.setImageResource(arrayList.get(position).getIcon());
holder.navIconNew.setImageResource(arrayList.get(position).getIcon());
holder.rootView.setBackgroundColor(arrayList.get(position).getColor());
holder.navTitle.setText(arrayList.get(position).getTitle());
}
#Override
public int getItemCount() {
return arrayList.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
ImageView navIcon, navIconNew;

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.
I want to create a list of items that have a background image and a TextView. Although it creates the RecyclerView normally and sets the text, the background image doesn't set.
This is my Adapter Class
public class Casino_Adapter extends RecyclerView.Adapter<Casino_Adapter.ViewHolder> {
private Data[] mDataset;
private ClickListener clickListener;
public Context context;
// Provide a suitable constructor (depends on the kind of dataset)
public Casino_Adapter(Data[] myDataset) {
this.mDataset = myDataset;
this.context = context;
}
#Override
public Casino_Adapter.ViewHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
// create a new view
View v = LayoutInflater.from(parent.getContext())
.inflate(R.layout.casino_card_row, parent, false);
// set the view's size, margins, paddings and layout parameters
ViewHolder vh = new ViewHolder(v);
return vh;
}
public static class ViewHolder extends RecyclerView.ViewHolder {
private final Context context = null;
// each data item is just a string in this case
public TextView mTextView;
public ImageView mImageView;
public CardView cardView;
//Typeface tf;
public ViewHolder(View v) {
super(v);
mTextView = (TextView) v.findViewById(R.id.text);
mImageView = (ImageView) v.findViewById(R.id.image);
cardView = (CardView) v.findViewById(R.id.card_view);
//cardView.setPreventCornerOverlap(false);
}
}
// Replace the contents of a view (invoked by the layout manager)
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
// - get element from your dataset at this position
// - replace the contents of the view with that element
holder.mTextView.setText(mDataset[position].getText());
holder.mImageView.setImageResource(mDataset[position].getImage());
}
public void setClickListener(ClickListener clickListener) {
this.clickListener = clickListener;
}
// Return the size of your dataset (invoked by the layout manager)
#Override
public int getItemCount() {
return mDataset.length;
}
public interface ClickListener {
public void itemClicked(View view, int pos);
}
}
I have a Fragment Class where I want the RecyclerView to be.
public class CasinoFragment extends Fragment {
protected RecyclerView recyclerView;
protected RecyclerView.Adapter mAdapter;
protected RecyclerView.LayoutManager mLayoutManager;
public CasinoFragment() {
// Required empty public constructor
}
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
initial();
}
private void initial() {
final Data datas[] =
{
new Data("This is an item", R.drawable.ic_home_white_36dp),
new Data("This is an item 2", R.drawable.car),
new Data("asdasd`sdads", R.drawable.car),
new Data("This is an item 3", R.drawable.car)
};
mAdapter = new Casino_Adapter(datas);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_casino, container, false);
recyclerView = (RecyclerView) view.findViewById(R.id.my_recycler_view);
mLayoutManager = new LinearLayoutManager(getActivity());
recyclerView.setLayoutManager(mLayoutManager);
recyclerView.setAdapter(mAdapter);
return view;
}
}
And these are the Setters that I use.
public class Data {
int image;
String text;
public Data(String title, int backimage)
{
this.text = title;
this.image = backimage;
}
public String getText()
{
return text;
}
public int getImage()
{
return image;
}
public void setText()
{
this.text=text;
}
public void setImageID()
{
this.image = image;
}
}

The result I get is the following.
The reason why you aren't seeing your image, is because it isn't actually visible.
Your rel_color layout has the same size attributes as your ImageView.
If you want to display a layout above the ImageView, you just need to remove the background of it, otherwise the ImageView will be hidden.
Just Like that. but remember your images dimensions must be low. in my case i used 200x200

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.

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"
