There is a spinner, there is also a RecyclerView, through the adapter I add to the RecyclerView TextView (Year) and ProgressBar (sales rating for the year) when choosing in a spiner for example 2 positions (car sales) progressBar should get this position and immediately change. how to implement it? I tried to do so
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() { @Override public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { if(position==0) { mCount=10; } mAdapter.notifyDataSetChanged(); } @Override public void onNothingSelected(AdapterView<?> parent) { } }); Then I just passed these values, but nothing happened.
public class PCAdapter extends RecyclerView.Adapter<PCAdapter.MyViewHolder> { private ArrayList<PC> dataSet; private Boolean check=true; public static class MyViewHolder extends RecyclerView.ViewHolder { TextView word,meaning,tdp,CoresThreads,Socket, Segment,Source,tv_progress_horizontal,e1,e2;
