语音功能(实现将语音转换成为文字)
//配置文件
这里所需jar包为:armeabi Msc.jar
//布局文件
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity" > <EditText android:id="@+id/content" android:layout_width="match_parent" android:layout_height="wrap_content" android:hint="您说点的什么。。。。。。。。。" android:layout_marginTop="20dp" /> <Button android:id="@+id/button" android:layout_below="@+id/content" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:text="按住请说话" /> </RelativeLayout>
