使用Okhttp框架和Gson开源类库，可以在GitHub上查阅API文档。

/google/gson

1. 逻辑代码

1.1 MainActivity 类

package com.example.myapplication;import androidx.appcompat.app.AppCompatActivity;import okhttp3.Call;import okhttp3.Callback;import okhttp3.OkHttpClient;import okhttp3.Request;import okhttp3.Response;import android.os.Bundle;import android.text.Editable;import android.util.Log;import android.view.View;import android.widget.Button;import android.widget.EditText;import android.widget.TextView;import com.example.myapplication.model.Fanyi;import com.google.gson.Gson;import com.google.gson.reflect.TypeToken;import org.jetbrains.annotations.NotNull;import java.io.IOException;import java.lang.reflect.Type;public class MainActivity3 extends AppCompatActivity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main4);Button btn1 = findViewById(R.id.fan_yi); // 翻译按钮final EditText editText = findViewById(R.id.yuan_wen); // 原文输入final TextView textView = findViewById(R.id.yi_wen); // 翻译后的文本btn1.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {Editable yuanWen = editText.getText();String url = "/translate?doctype=json&i=" + yuanWen;// Log.i("tag", url);// TODO http请求OkHttpClient okHttpClient = new OkHttpClient();Request request = new Request.Builder().url(url).get() // 默认就是GET请求，可以不写.build();Call call = okHttpClient.newCall(request);call.enqueue(new Callback() {// Callback回调函数 请求数据获取后执行@Overridepublic void onFailure(@NotNull Call call, @NotNull IOException e) {Log.e("tag", e.toString());}@Overridepublic void onResponse(@NotNull Call call, @NotNull Response response) throws IOException {String responseDate = response.body().string();Gson gson = new Gson();Type MembersType = new TypeToken<Fanyi>() {}.getType();Fanyi fanYi = gson.fromJson(responseDate,MembersType);// 转换成FanYi类String translateResult = fanYi.getTranslateResult().get(0).get(0).getTgt();Log.i("tag",translateResult +"");textView.setText(translateResult);}});}});}}

1.2 Fanyi 类

有道翻译接口返回的数据如图：

将json数据解析为java对象列表结构。

package com.example.myapplication.model;import java.util.ArrayList;public class Fanyi {private String type;private int errorCode;private int elapsedTime;private ArrayList<ArrayList<translateResult>> translateResult;public Fanyi() {}public Fanyi(String type, int errorCode, int elapsedTime, ArrayList<ArrayList<translateResult>> translateResult) {this.type = type;this.errorCode = errorCode;this.elapsedTime = elapsedTime;this.translateResult = translateResult;}public String getType() {return type;}public void setType(String type) {this.type = type;}public int getErrorCode() {return errorCode;}public void setErrorCode(int errorCode) {this.errorCode = errorCode;}public int getElapsedTime() {return elapsedTime;}public void setElapsedTime(int elapsedTime) {this.elapsedTime = elapsedTime;}public ArrayList<ArrayList<translateResult>> getTranslateResult() {return translateResult;}public void setTranslateResult(ArrayList<ArrayList<translateResult>> translateResult) {this.translateResult = translateResult;}}

1.3 translateResult 类

package com.example.myapplication.model;public class translateResult {private String src;private String tgt;public translateResult() {}public translateResult(String src, String tgt) {this.src = src;this.tgt = tgt;}public String getSrc() {return src;}public void setSrc(String src) {this.src = src;}public String getTgt() {return tgt;}public void setTgt(String tgt) {this.tgt = tgt;}}

2. 布局代码

2.1 XML 文件

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="/apk/res/android"xmlns:app="/apk/res-auto"xmlns:tools="/tools"android:layout_width="match_parent"android:layout_height="match_parent"tools:context=".MainActivity3"android:orientation="vertical"><EditTextandroid:id="@+id/yuan_wen"android:layout_width="match_parent"android:layout_height="300dp"android:gravity="top"android:textSize="25sp"android:textStyle="bold"android:text="今天天气真好！"/><Buttonandroid:id="@+id/fan_yi"android:layout_width="match_parent"android:layout_height="70dp"android:text="翻译"android:textSize="25sp"/><TextViewandroid:id="@+id/yi_wen"android:layout_width="match_parent"android:layout_height="300dp"android:text=""android:textSize="25sp"/></LinearLayout>
