6. drawable文件夹中添加edit_border.xml
1.进入有道智云主页，注册自己的账号(手机号验证码)，完善信息随意填
记得领取赠送的50元体验金(能用好久)
2.登录进来后，创建应用。根据需要选择语言翻译服务。
?我这里接入方式是API接入，因为用的是retrofit。注意IP地址不要填写，直接为空，就不会有IP限制
创建完成后，记下应用ID和应用密钥，等会会用到
3.?打开Android Studio，新建空的Activity项目
1.?新建项目，在build.gradle(app)添加retrofit依赖
implementation 'com.squareup.retrofit2:retrofit:2.4.0'
implementation 'com.squareup.retrofit2:converter-gson:2.4.0'
?2. 打开有道云文本翻译API接入文档，找到json文件示例
（ AndroidStudio下载一个GsonFormatPlus插件）
新建Java类来接收这个json文件，Alt+Insert或者右键选择Generate，选择GsonFormatPlus，会跳出这样一个对话框
?将API接入文档中的json文件示例复制粘贴到左边空白栏，点击OK就会自动生成代码。
3.新建一个接口类，获取json文件
import retrofit2.Call;
import retrofit2.http.POST;
import retrofit2.http.Query;
public interface GetResult {
@POST("api")
Call<TextRes> getTextRes(@Query("from") String from, @Query("to") String to,
@Query("appKey") String ID, @Query("salt") String salt,
@Query("sign") String sign, @Query("signType") String signType,
@Query("curtime") String curtime, @Query("q") String q);
}Call<TestRes>中TestRes是JavaBean类名?
4.?新建一个接口实现类来获取Call<>
import java.nio.charset.StandardCharsets;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import retrofit2.Call;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;
public class TextTranslator {
String q;
public TextTranslator(String s) {
this.q = s;
}
static String APP_KEY = "你的应用ID", signType = "v3";
static final String APP_SECRET = "你的应用密钥";
static String BASE_URL = "https://openapi.youdao.com/";
public Call<TextRes> getCall(String from, String to) {
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build();
final GetResult getR = retrofit.create(GetResult.class);
String salt = String.valueOf(System.currentTimeMillis());
String curtime = String.valueOf(System.currentTimeMillis() / 1000);
String sign = getDigest(APP_KEY + truncate(q) + salt + curtime + APP_SECRET);
return getR.getTextRes(from, to, APP_KEY, salt, sign, signType, curtime, q);
}
private static String truncate(String q) {
if (q == null) {
return null;
}
int len = q.length();
return len <= 20 ? q : (q.substring(0, 10) + len + q.substring(len - 10, len));
}
private static String getDigest(String string) {
if (string == null) {
return null;
}
char[] hexDigits = {'0', '1', '2', '3', '4', '5', '6', '7', '8',
'9', 'A', 'B', 'C', 'D', 'E', 'F'};
byte[] btInput = string.getBytes(StandardCharsets.UTF_8);
try {
MessageDigest mdInst = MessageDigest.getInstance("SHA-256");
mdInst.update(btInput);
byte[] md = mdInst.digest();
int j = md.length;
char[] str = new char[j * 2];
int k = 0;
for (byte byte0 : md) {
str[k++] = hexDigits[byte0 >>> 4 & 0xf];
str[k++] = hexDigits[byte0 & 0xf];
}
return new String(str);
} catch (NoSuchAlgorithmException e) {
return null;
}
}
}?5.更改activity_main.xml布局文件
<?xml version="1.0" encoding="utf-8"?>

<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="10dp" />
<stroke

android:color="@color/black" />
<padding
android:bottom="4dp"
android:left="6dp"

</shape>?7.在values文件夹中添加arrays.xml文件
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string-array name="language">
