Разработчик Android-приложения, SpeechRecouncer onResult не может быть вызван? [закрыто] ⇐ Android

[Anonymous]

• проверьте журнал, мы видим «语音识别已启动，isListening = true» и «录音按钮抬起，停止语音识别», но не можем получить текст в input_area И проверить журнал не стал столкнулся с onResults；
• Кроме того, забава onBeginningOfSpeech 和 onEndOfSpeech не была вызвана, поскольку мы не нашли соответствующие журналы,
  ps, AudioPermission хорош.
