使用SpeechRecognizer.ACTION_GET_SUPPORTED_LANGUAGES查询支持的语言时遇到问题。
private void queryLanguages() {
Intent i = new Intent(RecognizerIntent.ACTION_GET_LANGUAGE_DETAILS);
sendOrderedBroadcast(i, null);
}
现在,我知道它说在BroadcastizerIntent.DETAILS_META_DATA中指定了BroadcastReceiver,但我不确定如何访问它。
基本上我要问的是如何创建一个Intent来检索可用的语言数据?
答案 0 :(得分:2)
这是如何完成的:
Intent intent = new Intent(RecognizerIntent.ACTION_GET_LANGUAGE_DETAILS);
context.sendOrderedBroadcast(intent, null, new HintReceiver(),
null, Activity.RESULT_OK, null, null);
private static class HintReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
if (DBG)
Log.d(TAG, "onReceive(" + intent.toUri(0) + ")");
if (getResultCode() != Activity.RESULT_OK) {
return;
}
// the list of supported languages.
ArrayList<CharSequence> hints = getResultExtras(true)
.getCharSequenceArrayList(
RecognizerIntent.EXTRA_SUPPORTED_LANGUAGES);
}
}
注意:
这些是否实际提供取决于具体实施
