I am using RecyclerView and mounting a list with multiple buttons . I can change the color of button according to a if , if the condition is true it changes, but when I go up and down the list, it ends up changing other buttons that can not change the color.
Adapter
public class RVAdapterTp1 extends RecyclerView.Adapter<RVAdapterTp1.MyViewHolder> {
private ArrayList<horario> horarioI;
private ArrayList<horario> horarioO;
private LayoutInflater mLayoutInflater;
private MaterialDialog mMaterialDialog;
private Context mContext;
public RVAdapterTp1(Context c, ArrayList<horario> i, ArrayList<horario> o) {
this.horarioI = i;
this.horarioO = o;
mContext = c;
//mLayoutInflater = (LayoutInflater) c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.tp1_item, parent, false);
MyViewHolder mvh = new MyViewHolder((v));
return mvh;
}
@Override
public void onBindViewHolder( final MyViewHolder holder, final int position) {
if (position < horarioO.size()) {
holder.cvO.setText(horarioO.get(position).getIo());
holder.cvO.setVisibility(View.VISIBLE);
if (horarioO.get(position).getOb() == 0) {
holder.cvO.setBackgroundColor(Color.parseColor("#FFC107"));
holder.cvO.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mMaterialDialog = new MaterialDialog(mContext);
mMaterialDialog.setTitle("ATENÇÃO");
mMaterialDialog.setMessage(horarioO.get(position).getObs());
mMaterialDialog.setPositiveButton("OK", new View.OnClickListener() {
@Override
public void onClick(View v) {
mMaterialDialog.dismiss();
}
});
mMaterialDialog.show();
}
});
}
} else {
holder.cvO.setText("");
holder.cvO.setVisibility(View.INVISIBLE);
}
if (position < horarioI.size()) {
holder.cvI.setText(horarioI.get(position).getIo());
holder.cvI.setVisibility(View.VISIBLE);
Log.v("AQUIIIaaaaaa", holder.cvI.getText().toString());
if (horarioI.get(position).getOb() == 0) {
horarioI.get(position).setOb(1);
Log.v("AQUIII", holder.cvI.getText().toString());
holder.cvI.setBackgroundColor(Color.parseColor("#FFC107"));
