推荐答案

使用<一个href="https://developer.android.com/reference/android/speech/RecognizerIntent.html#ACTION_RECOGNIZE_SPEECH"相对=nofollow> ACTION_RECOGNIZE_SPEECH ：

private static final int RECOGNIZER_REQ_CODE = 1234;

Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
startActivityForResult(intent, RECOGNIZER_REQ_CODE);

请注意，您必须使用 startActivityForResult（）为 startActivity（）不支持。见上面的链接的文档的详细信息。

Please note that you have to use startActivityForResult() as startActivity() is not supported. See the above linked docs for details.
