I have a Recycler View to show a list of data and edit the text inside the Recycler View to allow the user to edit some number.
My app also resizes when the keyboard is displayed / hidden.
The application works great if I do not want to edit the elements that are located below. When I click to edit the text, it changes the screen size, shows the keyboard, focus holder, but it’s wrong: usually one before and sometimes 2.
I tried to track the problem and realized that the LinearLayoutMnager onFocusSearchFailed function returns an incorrect view.
Any idea why this could be?
Adapter
private final LinearLayoutManager linearLayoutManager; public Observable<double[][]> observable; private ObservableEmitter<double[][]> observe; List<Invoice> invoices = Collections.emptyList(); double[][] amounts; Context context; public AdjustInvoiceAdapter(List<Invoice> list, Context context, LinearLayoutManager linearLayoutManager) { this.invoices = list; this.context = context; this.linearLayoutManager = linearLayoutManager; amounts = new double[invoices.size()][1]; for (int i = 0; i < list.size(); i++) { amounts[i][0] = invoices.get(i).getAmountDue(); } observable = Observable.create(new ObservableOnSubscribe<double[][]> (){ @Override public void subscribe(ObservableEmitter<double[][]> emitter) throws Exception { observe = emitter; } }); } @Override public InvoiceHolder onCreateViewHolder(ViewGroup parent, int viewType) { View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item_adjust_invoice_payment_amount, parent, false); InvoiceHolder holder = new InvoiceHolder(view); return holder; } @Override public void onBindViewHolder(InvoiceHolder holder, final int position) { holder.update(invoices.get(position), amounts[position][0]); holder.amount.addTextChangedListener(new TextWatcher() { @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { } @Override public void onTextChanged(CharSequence s, int start, int before, int count) { } @Override public void afterTextChanged(Editable s) { if (s.length() == 0 || (s.length() == 1 && (s.toString().charAt(0)) == '-')) amounts[position][0] = 0.0; else amounts[position][0] = Double.parseDouble(s.toString()); observe.onNext(amounts); } }); } @Override public int getItemViewType(int position) { return position; } @Override public int getItemCount() { return invoices.size(); }
holder
public class InvoiceHolder extends RecyclerView.ViewHolder { EditText amount; TextView invoiceAmountDue; TextView invoiceId; TextView invoiceDueDate; TextInputLayout textInputLayout; private NumberFormat numberFormat = NumberFormat.getCurrencyInstance(Locale.US); public InvoiceHolder(View itemView) { super(itemView); invoiceId = (TextView) itemView.findViewById(R.id.invoice_number_text_view); invoiceDueDate = (TextView) itemView.findViewById(R.id.invoice_due_text_view); invoiceAmountDue = (TextView) itemView.findViewById(R.id.invoice_amount_due_text_view); amount = (EditText) itemView.findViewById(R.id.editText); textInputLayout = (TextInputLayout) itemView.findViewById(R.id.text_input_layout); } void update(Invoice invoice, double currentAmount) { textInputLayout.setHint("(" + numberFormat.format(invoice.getAmountDue())+")"); invoiceId.setText(invoice.getinvoiceId()); invoiceDueDate.setText(invoice.getInvoiceDueDate()); amount.setText(currentAmount); }
}
