在下面的代碼中，我有一個(gè)名為 mPreset 的按鈕。如果單擊該按鈕，則將 get 方法發(fā)送到服務(wù)器并嘗試獲取響應(yīng)。如果響應(yīng)成功，則打印 json 數(shù)據(jù)。但我的 light_id 沒有打印。任何人都可以幫助解決這個(gè)問題在下面的代碼中，我有一個(gè)名為 GetScheduler 的類，其中一個(gè)是字符串類型，其余兩個(gè)是整數(shù)類型數(shù)組。GetScheduler.java: public class GetScheduler { @SerializedName("status") private String status; @SerializedName("data") private DataClass data; public DataClass getData() { return data; } public void setData(DataClass data) { this.data= data; } public String getStatus() { return status; } public void setStatus(String status) { this.status = status; } public class DataClass { @SerializedName("light_id") private String light_id; @SerializedName("intensity") private int[] intensity; @SerializedName("cct") private int[] cct; public String getLight_id() { return light_id; } public void setLight_id(String light_id) { this.light_id = light_id; } public int[] getIntensity() { return intensity; } public void setIntensity(int[] intensity) { this.intensity = intensity; } public int[] getCct() { return cct; } public void setCct(int[] cct) { this.cct = cct; } }在下面的類中描述了名為 API 的接口API.java: public interface API { @retrofit2.http.GET("/gateway_schedule") retrofit2.Call<GetScheduler> getSchedulerData(); }Main.java: mPreset.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { getCCTAndIntensityValuesForPreset(); } }); private void getCCTAndIntensityValuesForPreset() { String url = "http://172.24.1.1:9000"; Retrofit retrofit = null; Log.d("123", "retrofit");

您需要?jiǎng)?chuàng)建 2 個(gè)類

像這樣改變你的反應(yīng)
public class GetScheduler {
@SerializedName("status")
private String status;
@SerializedName("data")
private DataClass data;
public DataClass getData() {
return data;
}
public void setData(DataClass data) {
this.data= data;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public class DataClass {
@SerializedName("light_id")
private String light_id;
@SerializedName("intensity")
private int[] intensity;
@SerializedName("cct")
private int[] cct;
public String getLight_id() {
return light_id;
}
public void setLight_id(String light_id) {
this.light_id = light_id;
}
public int[] getIntensity() {
return intensity;
}
public void setIntensity(int[] intensity) {
this.intensity = intensity;
}
public int[] getCct() {
return cct;
}
public void setCct(int[] cct) {
this.cct = cct;
}
}
}
如果你有數(shù)組響應(yīng)（我看到你沒有）你必須使用List<GetScheduler>否則你必須只使用GetScheduler
所以改變所有
List<GetScheduler>
到
GetScheduler
API.java
public interface API {
@retrofit2.http.GET("/gateway_schedule")
retrofit2.Call<GetScheduler> getSchedulerData();
}
和Main.java
private void getCCTAndIntensityValuesForPreset() {
try {
String url = "http://172.24.1.1:9000";
Retrofit retrofit = null;
Log.d("123", "retrofit");
if (retrofit == null) {
retrofit = new Retrofit.Builder()
.baseUrl(url)
.addConverterFactory(GsonConverterFactory.create())
.build();
Log.d("123", "build();");
}
API service = retrofit.create(API.class);
Call<GetScheduler> call=service.getSchedulerData();
Log.d("123", "Call<GetScheduler> call = service.getSchedulerData();");
call.enqueue(new Callback<GetScheduler>() {
@Override
public void onResponse(Call<GetScheduler> call, Response<GetScheduler> response) {
if(response!=null&&response.isSuccessful()){
String getLightId=response.body().getData().getLight_id().toString();
Toast.makeText(getApplicationContext(),"Light Id"+getLightId,Toast.LENGTH_LONG).show();
//String light_id=response.body()
int[] getIntensty=response.body().getData().getIntensity();
for(int i=0;i<getIntensty.length;i++){
getIntensty[i]=i;
}
int[] getCCT=response.body().getData().getCct();
for(int i=0;i<getCCT.length;i++){
getCCT[i]=i;
mCCT1.setProgress(getCCT[0]);
mCCT2.setProgress(getCCT[1]);
}
}
};
@Override
public void onFailure(Call<GetScheduler> call, Throwable t) {
t.printStackTrace();
}
});
}catch (Exception e) {
e.printStackTrace();
}
}
你必須onResponse像這樣改變這條線
String getLightId=response.body().getData().getLight_id().toString();
我建議您添加登錄 onFailure() 并查看 logCat 并刪除 try catch
@Override
public void onFailure(Call<List<GetScheduler>> call, Throwable t) {
t.printStackTrace();
}
