i have an Activity which has two tabs. Each tab has a RecyclerView and each RecyclerView has a specific Adapter. there is a button in each dataset of first tabs RecyclerView that deletes dataset in position and adds it to the next tab. My problem is that I should exit from Activityand enter again to see the added data in second tab. how can I update second tab immediately ?
public class QCRepairAdapter extends RecyclerView.Adapter<QCRepairAdapter.MyViewHolder> {
private LayoutInflater inflater;
List<QCInfo> data = Collections.emptyList();
public QCRepairAdapter(Context context, List<QCInfo> data) {
inflater = LayoutInflater.from(context);
this.data = data;
}
@Override
public QCRepairAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = inflater.inflate(R.layout.cards_qc_repair, parent, false);
MyViewHolder holder = new MyViewHolder(view);
return holder;
}
public void Delete(int position) {
data.remove(position);
notifyItemRemoved(position);
}
@Override
public void onBindViewHolder(final QCRepairAdapter.MyViewHolder holder, final int position) {
QCInfo current = data.get(position);
holder.projectName.setText(current.projectName);
holder.code.setText(current.code);
holder.operator.setText(current.operatorName);
}
@Override
public int getItemCount() {
return data.size();
}
class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
TextView projectName;
TextView code;
TextView operator;
ImageView btn_accept;
public MyViewHolder(final View itemView) {
super(itemView);
projectName = (TextView) itemView.findViewById(R.id.tv_card_qc_repair_name);
code = (TextView) itemView.findViewById(R.id.tv_card_qc_repair_code);
operator = (TextView) itemView.findViewById(R.id.tv_card_qc_repair_operatorName);
btn_accept = (ImageView) itemView.findViewById(R.id.iv_card_qc_repair_accept);
btn_accept.setOnClickListener(this);
}
@Override
public void onClick(View v) {
showDialog(v.getContext(), "تایید فرآیند ؟", "qcAccept", code.getText().toString(), getPosition());
}
}
private void showDialog(final Context context, String message, final String method, final String code, final int position) {
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("هشدار")
.setIcon(R.drawable.alert)
.setMessage(message)
.setPositiveButton("بله", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
BackgroundTask backgroundTask = new BackgroundTask(context);
backgroundTask.execute(method, code);
Delete(position);
}
})
.setNegativeButton("خیر", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
})
.create().show();
}
}
