我有一个RecyclerView，在我想要的最后一个editText上有4个editText，当按Enter时要集中在新的editTexts集的第一个editText上。
我的想法似乎仅在应用程序启动时才适用于第一行。
我尝试过的事情：
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
public int getItemCount() {
return modelArray.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
protected EditText codeET, perigrafiET, mmET, tmxET;
LinearLayout rvLayout;
public ViewHolder(@NonNull View itemView) {
super(itemView);
codeET = itemView.findViewById(R.id.code_et);
perigrafiET = itemView.findViewById(R.id.perigrafi_et);
mmET = itemView.findViewById(R.id.mm_et);
tmxET = itemView.findViewById(R.id.tmx_et);
rvLayout = itemView.findViewById(R.id.rv_layout);
codeET.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
@Override

modelArray.get(getAdapterPosition()).setModelCode(codeET.getText().toString());

}
@Override

});
mmET.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
@Override

modelArray.get(getAdapterPosition()).setModelMM(mmET.getText().toString());
}
@Override

});
tmxET.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
@Override

modelArray.get(getAdapterPosition()).setModelTmx(tmxET.getText().toString());
}
@Override
public void afterTextChanged(Editable editable) {
}
});
}
}

那么当在任何一行的最后一个editText上按下Enter时，怎么可能在底部创建一个新行，并专注于该行和这个editText内部呢？在我们的例子中，它是code editText。
