加入在：activity_main.xml


<Button
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:onClick="onText"
        android:text="語音辨識" />

<Button
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:onClick="onWeb"
        android:text="網頁搜尋" />

<ScrollView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >

<TextView
        android:id="@+id/tv"
        android:layout_width="fill_parent"/>


</ScrollView>



標記黃色區塊加入在：AndroidManifest.xml
可加可不加    要觸發onWeb(View v)才需要網路
