从翻新呼叫中获取数据并将其发送到其他活动

Question

当我在RecyclerView中单击某个项目时，我需要将详细信息发送到另一个活动。

// Here I call my service
public void getContactoById(Integer id) 
{
    apiManager.getContactoById(id).
            enqueue(new Callback<Contacto>() {
                @Override
                public void onResponse(Call<Contacto> call, Response<Contacto> response) {
                    if (response.isSuccessful()) {
                        // ???????? How send from here to 2nd Activity
                    }
                }

                @Override
                public void onFailure(Call<Contacto> call, Throwable t) {
                    Throwable x = t;
                }
            });
}

// In second Activity, I need to fill these controls with the values obtained from the service call
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_detail_contact);
  Service.getInstance().getContactoById(Integer.valueOf(contacto.getUserId()));

    imgFoto = (ImageView) findViewById(R.id.imgFoto);
    tvNombre = (TextView) findViewById(R.id.tvNombre);
    tvPhoneHome = (TextView) findViewById(R.id.tvPhoneHome);
    tvPhoneCellphone = (TextView) findViewById(R.id.tvPhoneCellphone);
    tvPhoneOffice = (TextView) findViewById(R.id.tvPhoneOffice);
    tvBirthDate = (TextView) findViewById(R.id.tvBirthDate);
}

我必须使用Retrofit进行调用，但是值仍然为空，因为Response在第二个Activity开始后数秒到达。可以从“呼叫响应”中更新控件吗？谢谢。

Answer 1

最好的方法是通过界面传递数据。 由于您的响应属于异步任务，因此我们需要通过界面传递它。

此接口可以在需要数据[您的api响应]的活动中实现。

我将向您展示如何实现：

步骤1：您需要创建界面并定义函数

public interface onAddTextViewCustomListener {
    void onAddText(String text);
}

第2步：在改造调用的“ onResponse”中使用此界面

//declare interface object
 onAddTextViewCustomListener onAddTextViewCustomListener; //listener custom

//add contructor
  this.onAddTextViewCustomListener = onAddTextViewCustomListener;

//call interface and pass data
 onAddTextViewCustomListener.onAddText("your api response");

步骤3：  实现活动接口，如下所示：

public class MainActivity extends AppCompatActivity implements onAddTextViewCustomListener

实现该方法后，您将在该活动中获取接口内部定义的方法。

  public void onAddText(String text) {
        Log.i("API RESPONSE", text);

//在这里执行您的逻辑。         }

这是我的最后一个项目，希望对您有所帮助

为您的recyclerview创建适配器，如下所示：

 public class ListAddressAdapter extends RecyclerView.Adapter<ListAddressAdapter.MyViewHolder> {
Context context;
List<ShippingInfoResponse> list;
ApiInterface apiInterface;
SelectAddress addressClicked;
deleteAddress deleteClicked;
boolean cardViewClicked = false;

public ListAddressAdapter(Context context, List<ShippingInfoResponse> list) {
    this.context = context;
    this.list = list;
}

@Override
public ListAddressAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.adress_list_item, parent, false);
    return new ListAddressAdapter.MyViewHolder(itemView);
}

@Override
public void onBindViewHolder(final ListAddressAdapter.MyViewHolder holder, final int position) {
    holder.cardView.setBackgroundColor(context.getResources().getColor(R.color.white));
    holder.txtShowName.setText(list.get(position).getName());
    holder.txtShowProvince.setText(list.get(position).getProvince());
    holder.txtShowCity.setText(list.get(position).getCity());
    holder.txtShowAddress.setText(list.get(position).getCity()+" "+list.get(position).getAddress());
    holder.txtShowNumber.setText(list.get(position).getMobile());
    holder.txtEdit.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(context, AddAddressActivity.class);
            intent.putExtra("id", list.get(position).getId());
            intent.putExtra("name", list.get(position).getName());
            intent.putExtra("province", list.get(position).getProvince());
            intent.putExtra("city", list.get(position).getCity());
            intent.putExtra("address", list.get(position).getAddress());
            intent.putExtra("postalCode", list.get(position).getPostalCode());
            intent.putExtra("mobile", list.get(position).getMobile());
            context.startActivity(intent);
        }
    });

    holder.txtSelect.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            addressClicked.selectAddress(
                    list.get(position).getName(),
                    list.get(position).getAddress(),
                    list.get(position).getMobile(),
                    list.get(position).getId(),
                    list.get(position).toString()
            );
            Log.e("select", "clicked");

        }
    });
    holder.txtDelete.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            deleteClicked.deleteAddress(list.get(position).getId());

        }
    });
}


@Override
public int getItemCount() {
    return list.size();
}

public class MyViewHolder extends RecyclerView.ViewHolder {
    TextView txtName, txtShowName;
    TextView txtProvince, txtShowProvince;
    TextView txtCity, txtShowCity;
    TextView txtAddress, txtShowAddress;
    TextView txtNumber, txtShowNumber;
    TextView txtDelete;
    TextView txtEdit;
    CardView cardView;
    LinearLayout linearTxtEdit;
    TextView txtSelect;

    public MyViewHolder(View itemView) {
        super(itemView);
        txtName = (TextView) itemView.findViewById(R.id.txt_name_in_list_address);
        txtShowName = (TextView) itemView.findViewById(R.id.txt_show_name);
        txtProvince = (TextView) itemView.findViewById(R.id.txt_province_in_list_address);
        txtShowProvince = (TextView) itemView.findViewById(R.id.txt_show_province);
        txtCity = (TextView) itemView.findViewById(R.id.txt_city_in_list_address);
        txtShowCity = (TextView) itemView.findViewById(R.id.txt_show_city);
        txtAddress = (TextView) itemView.findViewById(R.id.txt_address_in_list_address);
        txtShowAddress = (TextView) itemView.findViewById(R.id.txt_show_address);
        txtNumber = (TextView) itemView.findViewById(R.id.txt_number_in_list_address);
        txtShowNumber = (TextView) itemView.findViewById(R.id.txt_show_number);
        txtEdit = (TextView) itemView.findViewById(R.id.txt_edit);
        cardView = (CardView) itemView.findViewById(R.id.cardItem_address);
        linearTxtEdit = (LinearLayout) itemView.findViewById(R.id.linearTxtEdit);
        txtSelect = (TextView) itemView.findViewById(R.id.txt_select_address);
        txtDelete = (TextView) itemView.findViewById(R.id.txt_delete_Address);

        txtEdit.setTypeface(Application.vazirDigit);
        txtName.setTypeface(Application.vazirDigit);
        txtShowName.setTypeface(Application.vazirDigit);
        txtProvince.setTypeface(Application.vazirDigit);
        txtShowProvince.setTypeface(Application.vazirDigit);
        txtCity.setTypeface(Application.vazirDigit);
        txtShowCity.setTypeface(Application.vazirDigit);
        txtAddress.setTypeface(Application.vazirDigit);
        txtShowAddress.setTypeface(Application.vazirDigit);
        txtNumber.setTypeface(Application.vazirDigit);
        txtShowNumber.setTypeface(Application.vazirDigit);
        txtSelect.setTypeface(Application.vazirDigit);
        txtDelete.setTypeface(Application.vazirDigit);
    }
}

public interface SelectAddress {
    public void selectAddress(String name, String address, String number, int id, String position);
}

public void setOnSelectAddressClicked(SelectAddress selectAddressClicked) {
    this.addressClicked = selectAddressClicked;
}


public interface deleteAddress {
    public void deleteAddress(int id);
}


public void setOnDeleteClicked(deleteAddress deleteAddressClicked) {
    this.deleteClicked = deleteAddressClicked;
}

}

以及您的活动中：

 private void fillRecyclerView() {
    adapter = new ListAddressAdapter(this, info);
    RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(this);
    recyclerView.setLayoutManager(layoutManager);
    recyclerView.setItemAnimator(new DefaultItemAnimator());
    recyclerView.setAdapter(adapter);
    adapter.notifyDataSetChanged();
    avl.setVisibility(View.GONE);
    adapter.setOnSelectAddressClicked(new ListAddressAdapter.SelectAddress() {

        @Override
        public void selectAddress(String name, String address, String number, int id, String position) {
            Name = name;
            Address = address;
            Number = number;
            Id = id;
            deleteId=id;
            Log.e("Name", name);
            SelectAddressFromList();
        }

    });
    adapter.setOnDeleteClicked(new ListAddressAdapter.deleteAddress() {
        @Override
        public void deleteAddress(int id) {
            deleteId = id;
            Log.w("id", deleteId + "");
            deleteLastAddress();
            avl.setVisibility(View.GONE);
        }
    });
}

private void deleteLastAddress() {
    apiInterface = ApiClient.getClient(this).create(ApiInterface.class);
    Call<Void> call = apiInterface.deleteAddress(deleteId);
    call.enqueue(new Callback<Void>() {
        @Override
        public void onResponse(Call<Void> call, Response<Void> response) {
            Log.w("responceCodeDelete", response.code() + "");
            Log.w("responceMessage", response.message());
            info.clear();
            avl.setVisibility(View.GONE);
            getAllAddress();


        }

        @Override
        public void onFailure(Call<Void> call, Throwable t) {

        }
    });
}

private void SelectAddressFromList() {
    apiInterface = ApiClient.getClient(this).create(ApiInterface.class);
    Call<Void> call = apiInterface.sendShippingInfo(
            Name,

            "خوزستان"
            , "اهواز",
            Address,
            "4947118914",
            Number
    );
    call.enqueue(new Callback<Void>() {
        @Override
        public void onResponse(Call<Void> call, Response<Void> response) {
            Log.w("RspncCodSendAddressFrmLst", response.code() + "");
            if (response.isSuccessful()) {
                Intent intent = new Intent();
                intent.putExtra("Name", Name);
                intent.putExtra("Address", Address);
                intent.putExtra("id", Id);
                Log.w("sendingId", Id + "");
                setResult(RESULT_OK, intent);
                deleteLastAddress();
                finish();
            }
        }

        @Override
        public void onFailure(Call<Void> call, Throwable t) {

        }
    });
}

Answer 3

您可以使用

之类的其他方式

Intent intX=new Intent(this, otherActivity.class);
intX.putExtra("stringextra1","value extra1");
intX.putExtra("stringextra2","value extra2"); 
intX.putExtra("stringextra_x","value extra_x");
startActivityForResult(intX, 0);

和otherActivity类接收该额外的字符串

Answer 4

  

使用捆绑包

在Activity1中，传递数据：

Intent intent = new Intent(this, Activity2.class);    
Bundle bundle = new Bundle();
bundle.putString("key1",value1);
bundle.putInt("key2",value2);
...
intent.putExtras(bundle)
startActivity(intent);

在Activity2中，检索数据：

Bundle extras = getIntent().getExtras();
if (extras != null) {
    String value1 = extras.getString("key1");
    int value2 = extras.getInt("key2");
    ...
}

Answer 5

创建一个数组列表，然后您从api中获取数据，并将其添加到Arraylist中。 之后，在适配器中，使用该阵列列表中的数据将数据从一个活动发送到另一活动。

tv_title.setOnClickListener(new View.OnClickListener() {
       @Override
        public void onClick(View v) {
            Intent i = new Intent(mContext,WebviewActivity.class);
                  i.putExtra(INTENT_CHANNELURL,al_details.get(getLayoutPosition()).get(URL_WEB).toString ());
            i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            mContext.startActivity(i);
        }
    });

就我而言，我创建了一个名为al_details的Arraylist。
