I would like to change the font of my 'item' in recycleview with custom font. Anybody can help me with this? I manage to change the font for my header by using
header_title = (TextView) itemView.findViewById(R.id.header_title);
and
Typeface face_01 = Typeface.createFromAsset(itemView.getContext().getAssets(), "customfont/grb.otf");
header_title.setTypeface(face_01);
But i have no idea how to do that for item in arraylist.
Here is the java code for my adapter:-
public class ExpandableListAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
public static final int HEADER = 0;
public static final int CHILD = 1;
private List<Item> data;
public ExpandableListAdapter(List<Item> data) {
this.data = data;
}
#Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int type) {
View view = null;
Context context = parent.getContext();
float dp = context.getResources().getDisplayMetrics().density;
int subItemPaddingLeft = (int) (18 * dp);
int subItemPaddingTopAndBottom = (int) (5 * dp);
switch (type) {
case HEADER:
LayoutInflater inflater = (LayoutInflater) parent.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.list_header, parent, false);
ListHeaderViewHolder header = new ListHeaderViewHolder(view);
return header;
case CHILD:
TextView itemTextView = new TextView(context);
itemTextView.setPadding(subItemPaddingLeft, subItemPaddingTopAndBottom, 0, subItemPaddingTopAndBottom);
itemTextView.setTextColor(0x88000000);
itemTextView.setLayoutParams(
new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT));
return new RecyclerView.ViewHolder(itemTextView) {
};
}
return null;
}
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
final Item item = data.get(position);
switch (item.type) {
case HEADER:
final ListHeaderViewHolder itemController = (ListHeaderViewHolder) holder;
itemController.refferalItem = item;
itemController.header_title.setText(item.text);
if (item.invisibleChildren == null) {
itemController.btn_expand_toggle.setImageResource(R.drawable.circle_minus);
} else {
itemController.btn_expand_toggle.setImageResource(R.drawable.circle_plus);
}
itemController.btn_expand_toggle.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (item.invisibleChildren == null) {
item.invisibleChildren = new ArrayList<Item>();
int count = 0;
int pos = data.indexOf(itemController.refferalItem);
while (data.size() > pos + 1 && data.get(pos + 1).type == CHILD) {
item.invisibleChildren.add(data.remove(pos + 1));
count++;
}
notifyItemRangeRemoved(pos + 1, count);
itemController.btn_expand_toggle.setImageResource(R.drawable.circle_plus);
} else {

}
}
});
break;

itemTextView.setText(data.get(position).text);
break;
}
}
#Override

private static class ListHeaderViewHolder extends RecyclerView.ViewHolder {
public TextView header_title;
public ImageView btn_expand_toggle;
public Item refferalItem;
public ListHeaderViewHolder(View itemView) {
super(itemView);
header_title = (TextView) itemView.findViewById(R.id.header_title);

}
}
}
Gloabally define fontpath and typeface
Typeface typeface;
String fontpath = "fonts/KaushanScript-Regular.otf";
In your constructor do following
public ExpandableListAdapter(Context context,List<Item> data) {
typeface = Typeface.createFromAsset(context.getAssets(), fontpath);
this.data = data;
}
In your BindViewHolder
holder.itemTextView.setTypeface(typeface);

Actually this screen displays a set of questions and the task is to read the user entered or selected answer.

Please help me guys I am trying this since last 3 days...
I've implemented my own login too, but it didn't working properly.
I have a fragment containing a recyclerView.
When a user presses on one of their recorded exercise sets, the particular set is highlighted green.
Basically this allows them to update the weight/ reps for that particular set if they want to.
When a user then decides to press the update button, I will run a SQL query to update the weight/ reps as they entered, however I also need to deselect the selected set (recyclerView item).
I need the colour to return back to dark grey. How could this be achieved?

Create a separate method in your adapter for clearing the selection.
public void clearSelection() {
adapterPos = -1;
isSelected = false;
notifyDataSetChanged();
}
Then call adapter.clearSelection() from your update click listener.

how can I it?
Try this

If you have used recyclerview , its adapter has onBindViewHolder() method , which gives you a position variable. Use that to iterate through the list!
model.getEmbedded().getWpFeaturedMedias().get(position).getMediaDetails()
In my application i have custom adapter, adapter has image, and text when I scrolling the RecyclerView some items position automatic change
public class MyPhotosAdapter extends RecyclerView.Adapter<MyPhotosAdapter.ViewHolder> implements View.OnClickListener {
private PojoClasses.DashboardPhotos[] dashboardPhotoses;

Please help me if anyone have solution for that particular problem .
Thanks in advance
Put a default in your switch statement
default:
viewHolder.mImageViewPriority.setBackgroundColor("Default color here for other priorities");
break;
and put default values in else part of all your if else conditions
