我正在寻找可以使用Spinner
从服务器动态填充Retrofit 1.9
项目的示例程序,但如果有关于此要求的任何示例或者共享,我仍然无法找到任何人共享的样本方法。
应该如何做到这一点,因为事先感谢android有点难以找到解决方案!
这是我的spinneritem课程:
public class MySpinnerItem {
public MySpinnerItem(){
}
public MySpinnerItem(String text, Integer value) {
Text = text;
Value = value;
}
public String getText() {
return Text;
}
public void setText(String text) {
Text = text;
}
public Integer getValue() {
return Value;
}
public void setValue(Integer value) {
Value = value;
}
public String Text;
public Integer Value;
}
这是我的微调器适配器:
package first.service.precision.servicefirst;
import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;
import java.util.List;
/**
* Created by 4264 on 25-11-2015.
*/
public class MySpinnerAdapter extends ArrayAdapter<MySpinnerItem> {
private Context context;
private List<MySpinnerItem> objects;
public MySpinnerAdapter(Context context, int resource, List<MySpinnerItem> objects) {
super(context, resource, objects);
this.context = context;
this.objects = objects;
}
@Override
public void add(MySpinnerItem object) {
this.objects.add(object);
}
@Override
public int getCount() {
return objects.size();
}
@Override
public MySpinnerItem getItem(int position) {
return objects.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView label = new TextView(context);
label.setText(objects.get(position).getText());
return label;
}
@Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
TextView label = new TextView(context);
label.setText(objects.get(position).getText());
return label;
}
}
这是我为微调器设置适配器的片段:

我的疑问是我使用虚拟数据完成了它但是我需要将服务器的json响应绑定到我的微调器上我是怎么做到的。
答案 0 :(得分:1)
下面是设置微调器的示例
Spinner spinner = (Spinner) findViewById(R.id.spinner1);
ArrayAdapter<String> adapter;
List<String> data;
data = new ArrayList<>();
for (int i = 0; i < 20; i++)
data.add("Data " + (i + 1));
adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, data);
spinner.setAdapter(adapter);
这里数据是虚拟数据,在你的情况下它将是虚拟数据。

首先创建thetrofitapi界面
/**
* reCreated by goodlife on 1/11/2016.
*/
import java.util.List;
import retrofit.Callback;
import retrofit.client.Response;
import retrofit.http.Field;
import retrofit.http.FormUrlEncoded;
import retrofit.http.GET;
import retrofit.http.POST;
/**
* Created by Belal on 11/5/2015.
*/
public interface RetrofitInternetApi {
//@FormUrlEncoded, we have to write this if we want to send post data to the server.
//@POST, because we are using an HTTP Post request we have written this.
// Inside it we have the URL of the script that will be receiving the post request.
// Note that the URL is excluding the root URL. And we have defined the root URL in our MainActivity.
//@Field(“key”) String variable inside key we have to write what we have written inside $_POST[‘key’] in our script.
// And we have to specify it for all the values we are going to send.
//Callback<Response> callback it is also inside the retrofit library. It will receive the output from the server.
//But this is only an interface and the method is abstract.
//We will define the method inside fetchDepartmentName() method that is declared inside MainActivity.java.
@GET("/getDepartmentName.php")
public void getDepartmentName(Callback<List<DepartmentNoRealm>> response);
}
然后创建函数
private void fetchDepartmentName(){
//Creating a rest adapter
RestAdapter restAdapter = new RestAdapter.Builder()
.setEndpoint(ROOT_URL)
.build();
//Creating an object of our api interface
RetrofitInternetApi retrofitInternetApi = restAdapter.create(RetrofitInternetApi.class);
//While the app fetched data we are displaying a progress dialog
final ProgressDialog loading = ProgressDialog.show(getActivity(), "Fetching Data", "Please wait...", false, false);
//Defining the method
retrofitInternetApi.getDepartmentName(new Callback<List<DepartmentNoRealm>>() {
@Override
public void success(List<DepartmentNoRealm> list, Response response) {
//Dismissing the loading progressbar
loading.dismiss();
Log.d("JSON LIST",list.toString());
//Storing the data in our list
departmentNoRealmList = list;
//Calling a method to show the list
showListinSpinner(); }
@Override
public void failure(RetrofitError error) {
//you can handle the errors here
}
});
}
然后创建一个类模型
package myafya.safaricom.co.ke.myafya.model.realm;
/**
* Created by 001557 on 1/13/2016.
*/
public class DepartmentNoRealm {
public int departmentID;
public String departmentName;
public String departmentURLimage;
public int getDepartmentID() {
return departmentID;
}
public void setDepartmentID(int departmentID) {
this.departmentID = departmentID;
}
public String getDepartmentName() {
return departmentName;
}
public void setDepartmentName(String departmentName) {
this.departmentName = departmentName;
}
public String getDepartmentURLimage() {
return departmentURLimage;
}
public void setDepartmentURLimage(String departmentURLimage) {
this.departmentURLimage = departmentURLimage;
}
}
现在Spinner中的代码showList
//Our method to show list
private void showListinSpinner(){
//String array to store all the book names
String[] items = new String[departmentNoRealmList.size()];
//Traversing through the whole list to get all the names
for(int i=0; i<departmentNoRealmList.size(); i++){
//Storing names to string array
items[i] = departmentNoRealmList.get(i).getDepartmentName();
}
//Spinner spinner = (Spinner) findViewById(R.id.spinner1);
ArrayAdapter<String> adapter;
adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, items);
//setting adapter to spinner
spinnerDepartments.setAdapter(adapter);
//Creating an array adapter for list view
}
然后分享并轻松实现
我的JSON是
[
{
"departmentID": "1",
"departmentName": "Enterprise Business Unit (EBU)",
"departmentURLimage": "https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcSKOZmGNAA08NbHwRJrloAouWqs6r4x7BGXY4k-ULWiHuPEobHI"
},
{
"departmentID": "2",
"departmentName": "Consumer Business Unit (CBU)",
"departmentURLimage": "https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcQ0IAFhZ52KiG_0ck5VbBxweZWf_MEA9eRmgHAEr6CG-rUG_a2QEQ"
}
