接口
翻译接口
可以参考以下默认值
@GET("translate_a/single")
fun translate(
@Query("q") q: String,
@Query("client") content: String = "gtx",
@Query("dt") dt: String = "t",
@Query("dt") dt1: String = "bd",
@Query("dt") dt2: String = "rm",
@Query("dj") dj: String = "1",
@Query("ie") ie: String = "UTF-8",
@Query("oe") oe: String = "UTF-8",
@Query("sl") sl: String = "auto",
@Query("tl") tl: String = "en",
@Query("hl") hl: String = "zh-CN",
@Query("tk") tk: String = ""
): Observable<TranslationBean>
主要用到sl、tl和q这几个参数
- sl：原语种
- tl：翻译语种
- q：翻译文本
关于语种可以参考项目中Languages这个类，包含了100多个语种代码
- Languages
返回json对应TranslationBean.kt这个实体类

- sentences 字段含原文本和翻译文本
- dict 字段包含词典信息
- 解析获取对应字段的内容在 TranslationHelper 中
语音接口
其中主要用到 tl 和 q 参数，同上
可以参考以下默认值
@GET("translate_tts")
fun requestTTS(
@Query("q") q: String,
@Query("client") content: String = "gtx",
@Query("ie") ie: String = "UTF-8",
@Query("tl") tl: String = "en",
@Query("hl") hl: String = "zh-CN",
@Query("total") total: String = "1",
@Query("idx") idx: String = "0",
@Query("textlen") textlen: String = "0",
@Query("tk") tk: String = ""
): Call<ResponseBody>
翻译基本流程
项目采用MVP架构
- TranslationFragment：调用presenter接口进行请求翻译
mPresenter.translate(content, sl, tl)
- TranslationPresenter：调用RetrofitUtil进行网络请求，并回调TranslationView的接口刷新界面
- DBHelper：负责存取翻译记录
fun translate(content: String, sl: String = Lang.AUTO.CODE, translateLanguage: String) {
if (content.isEmpty()) {
toast(R.string.please_input_content)
return
}
val history = DBHelper.getHistory(content, sl, translateLanguage)
val translationBean =
JsonHelper.json2Object(history?.result ?: "", TranslationBean::class.java)
if (translationBean != null) {
parse(translationBean)
mViewRef?.get()?.refreshLiked(history?.liked == 1)
val translateText = TranslationHelper.getTranslateText(translationBean)
if (translateText.isNotEmpty()) {
play(translateText, translateLanguage)
copyToClipBoard(translateText)
}
log("获取到数据库翻译内容")
DBHelper.updateHistoryTime(history)
EventBus.getDefault().post(UpdateRecordEvent())
return
}
RetrofitUtil.translate(object : Subscriber<TranslationBean>() {
override fun onCompleted() {}
override fun onError(e: Throwable) {
e.printStackTrace()
log("失败")
}
override fun onNext(bean: TranslationBean) {
parse(bean)
val translateText = TranslationHelper.getTranslateText(bean)
mViewRef?.get()?.refreshLiked(false)
play(translateText, translateLanguage)
copyToClipBoard(translateText)
DBHelper.addHistory(content, sl, translateLanguage, bean)
EventBus.getDefault().post(UpdateRecordEvent())
}
}, content, sl, translateLanguage)
}
- TranslationHelper：负责解析数据
- TranslationView：刷新界面
private fun parse(bean: TranslationBean) {
val srcSymbol = TranslationHelper.getSrcSymbol(bean)
val translateSymbol = TranslationHelper.getTranslateSymbol(bean)
//音标显示逻辑
if (srcSymbol.isNotEmpty()) {
mViewRef?.get()?.showOrHideSoundSrcSymbol(true)
} else {
mViewRef?.get()?.showOrHideSoundSrcSymbol(false)
}
if (translateSymbol.isNotEmpty()) {
mViewRef?.get()?.showOrHideSoundTranslateSymbol(true)
} else {
mViewRef?.get()?.showOrHideSoundTranslateSymbol(false)
}
if (TranslationHelper.getDictText(bean).isNotEmpty()) {
mViewRef?.get()?.showOrHideDictInfo(true)
} else {
mViewRef?.get()?.showOrHideDictInfo(false)
}
mViewRef?.get()?.updateResult(
bean,
TranslationHelper.getSrcLang(bean),
TranslationHelper.getSrcText(bean),
TranslationHelper.getSrcSymbol(bean),
TranslationHelper.getTranslateText(bean),
TranslationHelper.getTranslateSymbol(bean),
TranslationHelper.getDictText(bean)
)
}
以上就是翻译的基本流程
复制查词功能实现
- 监听粘贴板变化并弹出Dialog风格的Activity，当在应用内复制时候，不弹出。
val clipBoardManager = getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager
clipBoardManager.addPrimaryClipChangedListener {
log("剪贴板变化")
if (ActivityCollector.size() == 0 && SettingHelper.getAutoTranslate()) {
val srcText = clipBoardManager.primaryClip?.getItemAt(0)?.text.toString()
DialogTranslateActivity.start(this, srcText)
}
}
通知栏常驻
- 启动一个前台服务 TranslationService 保活
override fun onStartCommand(intent: Intent?, flags: Int, startId: Int): Int {
log("启动服务")
val paddingFlag = 1
val pendingIntent = PendingIntent.getActivity(
this,
0,
Intent(this, MainDrawerActivity::class.java),
PendingIntent.FLAG_UPDATE_CURRENT,
null
)
val notificationBuilder = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val channelId = "translation"
val channelName = "翻译"
val importance = NotificationManager.IMPORTANCE_HIGH
createNotificationChannel(channelId, channelName, importance)
NotificationCompat.Builder(this, channelId)
.setNumber(paddingFlag)
} else {
NotificationCompat.Builder(this)
}
notificationBuilder
.setContentTitle(getString(R.string.app_name))
.setContentText(getString(R.string.notification_msg, getString(R.string.app_name)))
.setSmallIcon(R.drawable.ic_logo)
.setLargeIcon(BitmapFactory.decodeResource(resources, R.drawable.ic_logo))
.setContentIntent(pendingIntent)
startForeground(1, notificationBuilder.build())
return super.onStartCommand(intent, flags, startId)
}
离线翻译功能
将翻译过的记录保存下来，即每次请求网络翻译时候就保存记录
//sl：原语种代码
//translateLanguage：翻译语种代码
//bean：TranslationBean请求翻译的实体类
DBHelper.addHistory(content, sl, translateLanguage, bean)
通过History这个实体类保存翻译记录
fun addHistory(content: String, sl: String, tl: String, bean: TranslationBean) {
run {
try {
val history = History()
history.srcText = content
history.sl = sl
history.tl = tl
history.time = System.currentTimeMillis()
history.liked = 0
history.result = Gson().toJson(bean)
history.ttsPath = MD5.getMD5StrToLowerCase("$content$tl.mp3")
val saveResult = history.save()
if (saveResult) {
log("保存翻译成功")
} else {
loge("保存翻译失败")
}
} catch (e: Exception) {
e.printStackTrace()
loge("保存翻译失败")
}
}
}
History实体类
@Keep
class History : LitePalSupport() {
var srcText: String = ""
var sl: String = "en"
var tl: String = "en"
var time: Long = 0
var liked: Int = 0
//全路径
var ttsPath: String = ""
var result: String = ""
}
每次请求就先获取本地记录
val history = DBHelper.getHistory(content, sl, translateLanguage)
val translationBean =
JsonHelper.json2Object(history?.result ?: "", TranslationBean::class.java)
if (translationBean != null) {
parse(translationBean)
mViewRef?.get()?.refreshLiked(history?.liked == 1)
val translateText = TranslationHelper.getTranslateText(translationBean)
if (translateText.isNotEmpty()) {
play(translateText, translateLanguage)
copyToClipBoard(translateText)
}
log("获取到数据库翻译内容")
DBHelper.updateHistoryTime(history)
EventBus.getDefault().post(UpdateRecordEvent())
return
}
历史记录和单词本
- 单词本从数据库中按条件查找like = 1 的记录，，四种情况就是选中所要查找的语言
fun getLikedHistory(sl: String, tl: String) {
run {
try {
//四种情况
var historyList = mutableListOf<History>()
if (sl.isEmpty() && tl.isEmpty()) {
//查所有
historyList =
LitePal.where("liked = ?", "1").order("time desc").find(History::class.java)
}
if (sl.isNotEmpty() && tl.isNotEmpty()) {
historyList = LitePal
.where("sl = ? and tl = ? and liked = ?", sl, tl, "1")
.order("time desc")
.find(History::class.java)
}
if (sl.isEmpty() && tl.isNotEmpty()) {
historyList = LitePal
.where("tl = ? and liked = ?", tl, "1")
.order("time desc")
.find(History::class.java)
}
if (sl.isNotEmpty() && tl.isEmpty()) {
historyList = LitePal
.where("sl = ? and liked = ?", sl, "1")
.order("time desc")
.find(History::class.java)
}
val wordItemList = mutableListOf<WordItem>()
historyList.map {
val wordItem = WordItem()
wordItem.history = it
wordItem.checked = false
wordItemList.add(wordItem)
}
mViewRef?.get()?.updateWordList(wordItemList)
} catch (e: Exception) {
e.printStackTrace()
}
}
}
- 历史记录就是全部记录，四种情况就是选中所要查找的语言
fun getHistory(sl: String, tl: String) {
run {
try {
//四种情况
var historyList = mutableListOf<History>()
if (sl.isEmpty() && tl.isEmpty()) {
//查所有
historyList = (LitePal.order("time desc").find(History::class.java))
}
if (sl.isNotEmpty() && tl.isNotEmpty()) {
historyList = LitePal
.where("sl = ? and tl = ?", sl, tl)
.order("time desc")
.find(History::class.java)
}
if (sl.isEmpty() && tl.isNotEmpty()) {
historyList = LitePal
.where("tl = ?", tl)
.order("time desc")
.find(History::class.java)
}
if (sl.isNotEmpty() && tl.isEmpty()) {
historyList = LitePal
.where("sl = ?", sl)
.order("time desc")
.find(History::class.java)
}
val wordItemList = mutableListOf<WordItem>()
historyList.map {
val wordItem = WordItem()
wordItem.history = it
wordItem.checked = false
wordItemList.add(wordItem)
}
mViewRef?.get()?.updateWordList(wordItemList)
} catch (e: Exception) {
e.printStackTrace()
}
}
}
数据备份和恢复功能
将所有History记录取出来，封装成BackupBean，再转成json保存到文件中
val historyList = DBHelper.getAllHistory()
if (historyList.isEmpty()) {
toast(R.string.no_backup_data)
task.run()
return
}
val backupBean = BackupBean()
backupBean.data = historyList
val result = Gson().toJson(backupBean)
log("backupResult = $result")
val success = FileUtil.saveStringToFile(result, BACKUP_FILE_PATH)
if (success) {
toast(R.string.backup_success)
} else {
toast(R.string.backup_fail)
}
...
最后一个是百度的语音识别功能
项目中集成了百度语音识别，但控件被隐藏，逻辑还是有的，通过一个ImageView触发。
识别功能封装在baiduvoice模块中的BaiduVoiceHelper
object BaiduVoiceHelper : EventListener {
private var mEventManager: EventManager? = null
private var mRecognizedListenerList = mutableListOf<RecognizedListener>()
private var mRecognizedType: RecognizedType = RecognizedType.CHINESE
// private var mListener: RecognizedListener? = null
//重新识别
private var mNeedReRecognized = true
fun init() {
mEventManager = EventManagerFactory.create(App.context, "asr")
mEventManager?.registerListener(this)
}
fun setRecognizedListener(recognizedListener: RecognizedListener) {
mRecognizedListenerList.add(recognizedListener)
}
fun removeRecognised(recognizedListener: RecognizedListener) {
mRecognizedListenerList.remove(recognizedListener)
}
fun startRecognize(type: RecognizedType = mRecognizedType) {
mNeedReRecognized = true
mRecognizedType = type
val params = LinkedHashMap<String, Any>()
var event: String? = null
event = SpeechConstant.ASR_START // 替换成测试的event
// 基于SDK集成2.1 设置识别参数
params[SpeechConstant.ACCEPT_AUDIO_VOLUME] = false
// params.put(SpeechConstant.NLU, "enable");
// params.put(SpeechConstant.VAD_ENDPOINT_TIMEOUT, 0); // 长语音
// params.put(SpeechConstant.IN_FILE, "res:///com/baidu/android/voicedemo/16k_test.pcm");
// params.put(SpeechConstant.VAD, SpeechConstant.VAD_DNN);
if (mRecognizedType == RecognizedType.ENGLISH) {
params[SpeechConstant.PID] = 1737 //英语
} else {
params[SpeechConstant.PID] = 15362 //普通话搜索模型, 默认
}
/* 语音自训练平台特有参数 */
// params.put(SpeechConstant.PID, 8002);
// 语音自训练平台特殊pid，8002：搜索模型类似开放平台 1537 具体是8001还是8002，看自训练平台页面上的显示
// params.put(SpeechConstant.LMID,1068); // 语音自训练平台已上线的模型ID，https://ai.baidu.com/smartasr/model
// 注意模型ID必须在你的appId所在的百度账号下
/* 语音自训练平台特有参数 */
// 请先使用如‘在线识别’界面测试和生成识别参数。 params同ActivityRecog类中myRecognizer.start(params);
// 复制此段可以自动检测错误
AutoCheck(App.context, @SuppressLint("HandlerLeak")
object : Handler() {
override fun handleMessage(msg: Message) {
if (msg.what == 100) {
val autoCheck = msg.obj as AutoCheck
synchronized(autoCheck) {
val message =
autoCheck.obtainErrorMessage() // autoCheck.obtainAllMessage();
// txtLog.append(message + "\n")
log(message)
// Log.w("AutoCheckMessage", message);
}// 可以用下面一行替代，在logcat中查看代码
}
}
}, false).checkAsr(params)
var json: String? = null // 可以替换成自己的json
json = JSONObject(params as Map<*, *>).toString() // 这里可以替换成你需要测试的json
mEventManager?.send(event, json, null, 0, 0)
log("开始识别: 输入参数：$json")
}
fun stopRecognize() {
mNeedReRecognized = false
log("停止识别：ASR_STOP")
mEventManager?.send(SpeechConstant.ASR_STOP, null, null, 0, 0) //
}
fun destroy() {
stopRecognize()
mEventManager?.unregisterListener(this)
}
// 基于sdk集成1.2 自定义输出事件类 EventListener 回调方法
// 基于SDK集成3.1 开始回调事件
override fun onEvent(
name: String,
params: String?,
data: ByteArray?,
offset: Int,
length: Int
) {
var logTxt = "name: $name"
if (params != null && !params.isEmpty()) {
logTxt += " ;params :$params"
}
if (data != null) {
logTxt += " ;data length=" + data.size
}
log(logTxt)
if (params?.contains("final_result") == true) {
loge("最后识别结果: $logTxt")
try {
val jsonObject = JSONObject(params)
val result = jsonObject.getString("best_result")?:""
mRecognizedListenerList.map {
it.onResult(params, result)
}
} catch (e: Exception) {
e.printStackTrace()
}
}
if (name == "asr.exit" && mNeedReRecognized) {
startRecognize()
//重新识别
}
}
}
