У меня есть RecyclerView, у которого есть 4 editTexts в последнем editText, который я хочу, чтобы при нажатии Enter фокусировался на первом editText нового набора editTexts.
Кажется, моя идея работает только для первой строки при запуске приложения.
Что я пробовал:
EditTextModel.jave
public class EditTextModel {
private String modelCode, modelPerigrafi, modelMM, modelTmx;
public EditTextModel(String modelCode, String modelPerigrafi, String modelMM, String modelTmx) {
this.modelCode = modelCode;
this.modelPerigrafi = modelPerigrafi;
this.modelMM = modelMM;
this.modelTmx = modelTmx;
}
public String getModelCode() {
return modelCode;
}
public void setModelCode(String modelCode) {
this.modelCode = modelCode;
}
public String getModelPerigrafi() {
return modelPerigrafi;
}
public void setModelPerigrafi(String modelPerigrafi) {
this.modelPerigrafi = modelPerigrafi;
}
public String getModelMM() {
return modelMM;
}
public void setModelMM(String modelMM) {
this.modelMM = modelMM;
}
public String getModelTmx() {
return modelTmx;
}
public void setModelTmx(String modelTmx) {
this.modelTmx = modelTmx;
}
}
RecyclerViewAdapter.java
public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder> {
private LayoutInflater inflater;
public static ArrayList<EditTextModel> modelArray;
private Context mContext;
private MainActivity mainActivity;
private RecyclerView recyclerViewPassed;
public RecyclerViewAdapter(Context mContext, ArrayList<EditTextModel> modelArray, RecyclerView recyclerViewPassed) {
this.mContext = mContext;
inflater = LayoutInflater.from(mContext);
this.modelArray = modelArray;
this.recyclerViewPassed = recyclerViewPassed;
}
@NonNull
@Override
public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View view = inflater.from(parent.getContext()).inflate(R.layout.rv_row, parent, false);
ViewHolder holder = new ViewHolder(view);
return holder;
}
@Override
public void onBindViewHolder(@NonNull ViewHolder holder, final int position) {
holder.codeET.setText(modelArray.get(position).getModelCode());
holder.perigrafiET.setText(modelArray.get(position).getModelPerigrafi());
holder.mmET.setText(modelArray.get(position).getModelMM());
holder.tmxET.setText(modelArray.get(position).getModelTmx());
holder.tmxET.setOnEditorActionListener(new TextView.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (event == null || event.getAction() != KeyEvent.ACTION_DOWN)
return false;
modelArray.add(new EditTextModel("", "", "", ""));
notifyDataSetChanged();
recyclerViewPassed.scrollToPosition(modelArray.size());
holder.codeET.requestFocus();
return true;
}
});
holder.rvLayout.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(mContext, modelArray.get(position).getModelTmx() + " " + modelArray.get(position).getModelPerigrafi(), Toast.LENGTH_SHORT).show();
}
});
}
@Override

return modelArray.size();

Итак, как это возможно, если нажать Enter при последнем editText в зависимости от того, чтострока, чтобы создать новую строку внизу и сфокусироваться на этой строке и внутри этого editText? В нашем случае это code editText.
