Изменение распознавания речи без всплывающего окна

Question

Я совершенно не знаком с Android, и я решил создать приложение для поиска Siri, которое отлично работает, я искал, прежде чем спрашивать, но я не могу заставить его работать: Android speech Recognition App Without Pop Up

Так что я хочу скрыть всплывающее окно в своем приложении для Android, но я действительно не понимаю, как это сделать должным образом. Я буду очень рад, если кто-то поможет мне в этом. Я уже добавил необходимые разрешения в Android Manifest ...

Вот мой полный источник:

Answer 1

Шаг 1

В Android Manifest.xml, добавить разрешение.

<uses-permission android:name="android.permission.RECORD_AUDIO" /> 

Шаг 2 На экране Макет я с помощью кнопки переключения для запуска/остановки голосового прослушивания.

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" > 

    ....... 

    <ToggleButton 
     android:id="@+id/toggleButton1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentTop="true" 
     android:layout_centerHorizontal="true" 
     android:layout_marginTop="26dp" 
     android:text="ToggleButton" /> 

...... 

</RelativeLayout>
