I have a border between parent and my cell. How to delete it ?
I search but I don't find where is the problem in my code.
Main class :
final RecyclerView rv = (RecyclerView) findViewById(R.id.contentMain_rv_1);
rv.setLayoutManager(new LinearLayoutManager(this));
rv.setAdapter(new MainActivityRecyclerViewAdapter());
Adapter :
public class MainActivityRecyclerViewAdapter extends RecyclerView.Adapter<MainActivityRecyclerViewAdapter.MyViewHolder> {
private final List<Pair<String, String>> characters = Arrays.asList(
Pair.create("Lyra Belacqua", "01/01/2001"),
Pair.create("Pantalaimon", "01/01/2002."),
Pair.create("Roger Parslow", "01/01/2003"),
Pair.create("Lord Asriel", "01/01/2004"),
Pair.create("Marisa Coulter", "01/01/2005."),
Pair.create("Iorek Byrnison", "01/01/2006."),
Pair.create("Serafina Pekkala", "01/01/2007."),
Pair.create("Lee Scoresby", "01/01/2008."),
Pair.create("Ma Costa", "01/01/2009"),
Pair.create("John Faa", "01/01/2010")
);
@Override
public int getItemCount() {
return characters.size();
}
@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
LayoutInflater inflater = LayoutInflater.from(parent.getContext());
View view = inflater.inflate(R.layout.list_cell_main, parent, false);
return new MyViewHolder(view);
}
@Override
public void onBindViewHolder(MyViewHolder holder, int position) {
Pair<String, String> pair = characters.get(position);
holder.display(pair);
}
public class MyViewHolder extends RecyclerView.ViewHolder {
private final TextView name;
private final TextView description;
private Pair<String, String> currentPair;
public MyViewHolder(final View itemView) {
super(itemView);
name = ((TextView) itemView.findViewById(R.id.name));
description = ((TextView) itemView.findViewById(R.id.description));
itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
new AlertDialog.Builder(itemView.getContext())
.setTitle(currentPair.first)
.setMessage(currentPair.second)
.show();
}
});
}
public void display(Pair<String, String> pair) {
currentPair = pair;
name.setText(pair.first);
description.setText(pair.second);
}
}
