到网站：百度翻译开放平台下载Java版本的demo
使用demo中的三个文件，main不用
默认返回的result内容是这样的:
{"from":"en","to":"zh","trans_result":[{"src":"Sure! Here's a short paragraph in English: ","dst":"\u5f53\u7136\u8fd9\u91cc\u6709\u4e00\u5c0f\u6bb5\u82f1\u8bed\uff1a"},{"src":"\"The sun was setting behind the distant hills, casting a warm golden glow over the tranquil countryside. Birds chirped softly in the trees, and a gentle breeze rustled through the leaves. As evening descended, the sky turned shades of pink and orange, painting a breathtaking canvas above. It was a moment of serene beauty, a peaceful pause in the hustle and bustle of life.\"","dst":"\u201c\u592a\u9633\u843d\u5728\u8fdc\u5904\u7684\u5c71\u4e18\u540e\u9762\uff0c\u7ed9\u5b81\u9759\u7684\u4e61\u6751\u6295\u4e0b\u4e86\u6e29\u6696\u7684\u91d1\u8272\u5149\u8292\u3002\u9e1f\u513f\u5728\u6811\u4e0a\u8f7b\u8f7b\u5730\u9e23\u53eb\uff0c\u5fae\u98ce\u5728\u6811\u53f6\u4e2d\u6c99\u6c99\u4f5c\u54cd\u3002\u591c\u5e55\u964d\u4e34\uff0c\u5929\u7a7a\u53d8\u6210\u4e86\u7c89\u7ea2\u8272\u548c\u6a59\u8272\uff0c\u5728\u4e0a\u9762\u753b\u51fa\u4e86\u4e00\u5e45\u4ee4\u4eba\u60ca\u53f9\u7684\u753b\u5e03\u3002\u8fd9\u662f\u4e00\u4e2a\u5b81\u9759\u7684\u7f8e\u4e3d\u65f6\u523b\uff0c\u662f\u751f\u6d3b\u55a7\u56a3\u4e2d\u7684\u4e00\u4e2a\u5e73\u9759\u7684\u505c\u987f\u3002\u201d"}]}使用下面的代码，会自动将结果提取出来：
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;public class baidutranslation {private static final String APP_ID = "";private static final String SECURITY_KEY = "";public static void baiduTranslation(String ocrText, String src, String tgt, TranslationListener listener) {// 创建一个 AsyncTask 来执行网络请求TranslationTask task = new TranslationTask(ocrText, src, tgt, listener);task.execute();}private static class TranslationTask extends AsyncTask<Void, Void, String> {private String ocrText;private String src;private String tgt;private TranslationListener listener;public TranslationTask(String ocrText, String src, String tgt, TranslationListener listener) {this.ocrText = ocrText;this.src = src;this.tgt = tgt;this.listener = listener;}@Overrideprotected String doInBackground(Void... voids) {// 在后台线程中执行网络请求TransApi api = new TransApi(APP_ID, SECURITY_KEY);return api.getTransResult(ocrText, src, tgt);}@Overrideprotected void onPostExecute(String result) {// 在 UI 线程中处理网络请求的结果，并将提取出来的翻译文本传递给监听器if (listener != null) {try {JSONObject jsonResult = new JSONObject(result);JSONArray transResult = jsonResult.getJSONArray("trans_result");StringBuilder translatedText = new StringBuilder();for (int i = 0; i < transResult.length(); i++) {JSONObject item = transResult.getJSONObject(i);translatedText.append(item.getString("dst"));}listener.onTranslationResult(translatedText.toString());} catch (JSONException e) {e.printStackTrace();}}}}public interface TranslationListener {void onTranslationResult(String result);}
}在其他函数中调用：
// 执行翻译操作baidutranslation.baiduTranslation(ocrText, src, "zh", new baidutranslation.TranslationListener() {@Overridepublic void onTranslationResult(String result) {// 处理翻译结果textView.setText(ocrText+"\n\n 翻译结果： \n\n " + result);}});
)
