I am develop android app which i need to download data(products details,images) from my server using httpclient the problem is i need to wait until all data has finished download. i need to show data which has been downloaded in recylerview while other are continue downloading. Thanks in Advance

What I have tried:

var responseBooked = await client.GetAsync("url");
        //will always throw an exception if not successful
        responseBooked.EnsureSuccessStatusCode();
        if (responseBooked.Content != null)
        {
        var responseContent = await responseBooked.Content.ReadAsStringAsync();
        mBcomplist = Newtonsoft.Json.JsonConvert.DeserializeObject<List<busCompList>> 
                      (responseContent);
        //Create our layout manager<pre lang="c#">

SimpleItemDecorator itemDecor = new SimpleItemDecorator(Context);
mRecyclerView.AddItemDecoration(itemDecor);

mLayoutManager = new LinearLayoutManager(Context);
mRecyclerView.SetLayoutManager(mLayoutManager);

recycleViewAdapter = new CompAdapter(mBcomplist,"Bus");
mRecyclerView.SetAdapter(recycleViewAdapter);
