[英]Send data inside recyclerview with button in Fragment
我有 2 個布局,其中 Fragment 的第一個布局和 RecyclerView 的第二個布局。 我在 RecyclerView 中創建了 CardView,每個 CardView 都有一些數據。 我在 RecyclerView 下方創建了按鈕,其中用於在 CardView 上發送數據的按鈕的功能。 我的問題是當我單擊 Fragment 中的按鈕時,我不知道如何發送數據。

當我選擇 RadioButton 時,只會獲取 RadioButton 中的數據。 當我點擊按鈕時,數據將被發送到另一個活動。
適配器回收器視圖:
public class AdapterGetAddress extends RecyclerView.Adapter<AdapterGetAddress.ViewHolder> {
Context context;
private List<ModelGetAddress> modelGetAddressList;
private BaseApiService baseApiService;
private int previousSelected = -1;
public AdapterGetAddress(Context context, List<ModelGetAddress> modelGetAddressList) {
this.context = context;
this.modelGetAddressList = modelGetAddressList;
}
@NonNull
@Override
public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.row_address, parent, false);
@Override
public void onBindViewHolder(@NonNull ViewHolder holder, final int position) {
final ModelGetAddress adapterAddress = modelGetAddressList.get(position);
}
@Override
public int getItemCount() {
return modelGetAddressList.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
private TextView nameUser, addressUser, streetName, blokAddressUser, cityAddressUser, countryUser, phoneUser;
private RadioButton radioButton;
public ViewHolder(@NonNull View itemView) {
super(itemView);
nameUser = itemView.findViewById(R.id.nameUser);
addressUser = itemView.findViewById(R.id.addressUser);
streetName = itemView.findViewById(R.id.streetName);
countryUser = itemView.findViewById(R.id.countryAddressUser);
blokAddressUser = itemView.findViewById(R.id.blokAddressUser);
cityAddressUser = itemView.findViewById(R.id.cityAddressUser);
phoneUser = itemView.findViewById(R.id.phoneUser);
radioButton = itemView.findViewById(R.id.radioButton);
radioButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
previousSelected = getAdapterPosition();
notifyItemRangeChanged(0, modelGetAddressList.size());
// I want this All String will be send when i click button in Fragment
String getNameUser = nameUser.getText().toString();
String getAddressUser = streetName.getText().toString();
String getCountryUser = countryUser.getText().toString();
String getBlokUser = blokAddressUser.getText().toString();
String getCityUser = cityAddressUser.getText().toString();
String getPhoneUser = phoneUser.getText().toString();
}
});
}
}
}
片段中的代碼:
public class MenuAddressFragment extends Fragment {
private Button gunakanAlamat;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_menu_address, container, false);
gunakanAlamat = view.findViewById(R.id.gunakanAlamat);
gunakanAlamat.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// Here's were i'm stuck
}
});
return view;
}
}
您可以通過接口解決此問題。
public interface ItemClickedCallback{
void onItemClicked(String nameUser //, the other data you wanna pass );
}
通過適配器的構造函數傳遞它。
使用此適配器構造函數
ItemClickedCallback callback;
public AdapterGetAddress(Context context, List<ModelGetAddress> modelGetAddressList, ItemClickedCallback callback) {
this.context = context;
this.modelGetAddressList = modelGetAddressList;
this.callback= callback;
}
檢查任何項目的單選按鈕時; 調用接口方法,像這樣。
radioButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
previousSelected = getAdapterPosition();
notifyItemRangeChanged(0, modelGetAddressList.size());
// I want this All String will be send when i click button in Fragment
String getNameUser = nameUser.getText().toString();
String getAddressUser = streetName.getText().toString();
String getCountryUser = countryUser.getText().toString();
String getBlokUser = blokAddressUser.getText().toString();
String getCityUser = cityAddressUser.getText().toString();
String getPhoneUser = phoneUser.getText().toString();
callback.onItemClicked(getNameUser //, the rest..);
}
});
現在,當您在片段中初始化適配器時,通過構造函數創建新接口並將數據分配給這樣的類變量。
public class MenuAddressFragment extends Fragment {
private Button gunakanAlamat;
private String nameUser_;
// the rest...
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_menu_address, container, false);
AdapterGetAddress adapter = new AdapterGetAddress(getActivity, list, new ItemClickedCallback() {
@Override
public void onItemClicked(String userName //, the rest..) {
// assign to the class variable like this
nameUser_ = userName;
// the rest..
}
}););
gunakanAlamat = view.findViewById(R.id.gunakanAlamat);
gunakanAlamat.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// Use the data as you want..
}
});
return view;
}
}
