最近学习android写了一个算的上是应用的app，功能很简单，利用google 提供的translate服务将输入的字符翻译成想要的语言（比如英汉翻译）和http://translate.google.cn/差不多（这里我直接应用了google-api-translate-java-0.92.jar这个jar包，操作很简单，方便，嘿嘿），还有利用android的TextToSpeech进行speech翻译的结果，由于android的TextToSpeech只支持English，French，German，Italian，Spanish，所以只有翻译的目标语言是上面的语种时才进行speech；还有功能就是将翻译的结果能以email/msg的形式发送消息给别人。写这个程序的重点在于学习利用AIDL进行process间的信息传递（关于aidl的知识google下可以找到很多，呵呵）
定义activity访问translate service的代码段：
private ServiceConnection mTranslateConn = new ServiceConnection() {
public void onServiceConnected(ComponentName name, IBinder service) {
mTranslateService = ITranslate.Stub.asInterface(service);
if (mTranslateService != null) {
mTranslateButton.setEnabled(true);
} else {
mTranslateButton.setEnabled(false);
mStatusView.setText(getString(R.string.error));
log("Unable to acquire TranslateService");
}
}
public void onServiceDisconnected(ComponentName name) {
mTranslateButton.setEnabled(false);
mTranslateService = null;
}
};
google translate service的应用：
GoogleAPI
.setHttpReferrer("http://code.google.com/p/google-api-translate-java/");
String translatedText = Translate.execute(text, Language
.fromString(from), Language.fromString(to));
TextToSpeech的应用：
@Override
public void onInit(int status) {
// TODO Auto-generated method stub
if (status == TextToSpeech.SUCCESS) {
Language to = (Language) mToButton.getTag();
String toShortName = to.getShortName();
int result = tts.setLanguage(new Locale(toShortName));
if (result == TextToSpeech.LANG_MISSING_DATA ||
result == TextToSpeech.LANG_NOT_SUPPORTED) {
Log.e(TAG, "Language is not available.");
} else {
// sayText();
}
} else {
// Initialization failed.
Log.e(TAG, "Could not initialize TextToSpeech.");
}
}
private void sayText() {
String sayInfo = mToEditText.getText().toString();
Language to = (Language) mToButton.getTag();
String toShortName = to.getShortName();
tts.setLanguage(new Locale(toShortName));
tts.speak(sayInfo, TextToSpeech.QUEUE_FLUSH,null);
}
最后send msg的应用：
private void sendEmail() {
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, mToEditText.getText());
startActivity(Intent.createChooser(intent, null));
}
恩，很简单吧，呵呵，不过还是很有成就感的说，嘿嘿。
