How can I display the category between (example)(3 and 7) in firebase ?
foodList.orderByChild("menuId").startAt(3).endAt(7).equalTo(categoryID)
this is my code :
private void loadListFood(String categoryID)
adapter = new FirebaseRecyclerAdapter<Food, FoodViewHolder>(Food.class,R.layout.food_item,FoodViewHolder.class,
foodList.orderByChild("menuId").startAt(3).endAt(7).equalTo(categoryID)
)
@Override
protected void populateViewHolder(FoodViewHolder viewHolder, Food model, int position)
viewHolder.food_name.setText(model.getName());
viewHolder.food_time.setText(model.getPrice());
Picasso.with(getBaseContext()).load(model.getImage()).into(viewHolder.food_image);
mDialog.dismiss();
final Food local = model ;
viewHolder.setItemClickListener(new ItemClickListener()
@Override
public void onClick(View view, int position, boolean isLongClick)
Intent intent = new Intent(FoodList.this,FoodDetail.class);
intent.putExtra("FoodId",adapter.getRef(position).getKey());
startActivity(intent);
);
;
recyclerView.setAdapter(adapter);

Can you attach your firebase structure. It's difficult to tell what's happening without that. And also, post what exception are you getting.

As the error says:
java.lang.IllegalArgumentException: Can't call equalTo() and startAt() combined
You cannot use both methods equalTo() and startAt() in a single call. If you want to sort your records according to multiple propeties, please take a look at my answer from this post, where I have explained how you can achieve this using a a combined property.

Can you attach your firebase structure. It's difficult to tell what's happening without that. And also, post what exception are you getting.

@IbrahimHJabaly Keep in mind that Stack Overflow is an incredibly inefficient interactive debugger. If you get an exception, copy/paste the exact error message and stack trace into your question, so that we can see what you're getting.
