I added popup menu on picture_item of recycle view and when we press delete button of popup menu I send String path of that image to deletePhoto(item); and that method delete image.
after delete image we have to manually refresh fragment by pull refresh But can add any automatic method for refreshing fragment In this case?
Please see deletePhoto method where I deleted photo but when
I tried refresh with removepos method its crash
I tried also many methods from stackoverflow but did not worked on my case
Please help me

You have already done everything uncomment your removeItem method and add pictureAdapter.notifyDataSetChanged() at the end of removeItem method
This will reload the data set of your adapter
If you know the position of the deleted element you can use
pictureAdapter.notifyItemRemoved(position)
This will tell your adapter you remove an item from the data set on a specific position

Android Widget with collection (ListView) not displaying items

I am trying to do a simple widget for my app, which displays data from an API on the widget using ListView, but the list is empty even tho Logs says that the data was downloaded successfully.
Blank listView is displayed with no data in it. No errors are shown. What's the cause of it?

I found my mistake, turns out my API call shouldn't be asynchronous because as the documentation says:
public void onDataSetChanged() ->
You can do heaving lifting in here, synchronously. For example, if you need to process an image, fetch something from the network, etc., it is ok to do it here, synchronously. The widget will remain in its current state while work is being done here, so you don't need to worry about locking up the widget.
So getting my data from Asynchronous call was the reason why data wasn't displayed

Please, help me fix this problem.

You need to set the width and height of your EditText in your layout file you cannot set these properties to 0dp. If you want to set this according to screen size then you can use layout_weight in your xml.Here you can know about layout_weight usage
If you are using constraintLayout in your layout you can see this link. Responsive layout designing with constraint layout

How can I put drawable image into gridview?

I have a gridview with 5 columns, how could add in column 4 and 5, images that I have in drawable folder? The problem is that being a String arraylist not catch me drawable because it is an integer.
This is my XML:

//Afegim la capçalera de la grid
lineasPedido.add("Plat");
