您好，下面的代码描述了服务器的json请求和json响应，我们将按钮命名为ADD，如果您按下ADD按钮，则将名称和级别作为请求发送，并根据请求获取状态来自服务器。
我在执行错误的地方找不到错误。我没有从服务器得到任何响应。
Add.java：
Add.setOnClickListener (new View.OnClickListener ( ) {
@Override
public void onClick(View v) {
final String name = et_building.getText().toString();
final String level = "1";
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(interceptor).build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(API.URL_BASE)
.client(client)
.addConverterFactory(GsonConverterFactory.create())
.build();
API service = retrofit.create(API.class);
try{
JSONObject parmobject=new JSONObject ();
parmobject.put("name",name);
parmobject.put("level",level);
Call<NewBuilding> userCall = service.getbuildinglist (parmobject.toString ());
userCall.enqueue(new Callback<NewBuilding> () {
@Override
public void onResponse(Call<NewBuilding> call, Response<NewBuilding> response) {
if (response != null && response.code ()==200) {
JSONObject obj = null;
try {
obj = new JSONObject (String.valueOf (response));
status=obj.getJSONObject (name).toString ();
} catch (JSONException e) {
Log.e("My App", "Could not parse malformed JSON:");
}
if(status.equalsIgnoreCase ("success")){
makeText(getActivity (), "Building successfully Added", Toast.LENGTH_SHORT).show();
arrayList.add (name);
adapter.notifyDataSetChanged ();
}
} else {
makeText(getActivity (), "Please try again for Adding New Building", Toast.LENGTH_SHORT).show();
}
}
@Override
public void onFailure(Call<NewBuilding> call, Throwable t) {
t.printStackTrace ();
}
});
} catch (JSONException e) {
e.printStackTrace();
}
}
});
POJO类：
NewBuilding.java：
public class NewBuilding {
@SerializedName ("status")
@Expose
private String status;
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
}
