界面布局：

<?xml version="1.0" encoding="utf-8"?><ScrollViewxmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="fill_parent"android:layout_height="fill_parent"><LinearLayout  android:orientation="vertical"  android:layout_width="fill_parent"  android:layout_height="fill_parent">  <Button  android:id="@+id/ButtonShot"  android:layout_width="fill_parent"  android:layout_height="wrap_content"  android:text="拍照"/>  <Button  android:id="@+id/ButtonVideo"  android:layout_width="fill_parent"  android:layout_height="wrap_content"  android:text="录像"/>  <Button  android:id="@+id/ButtonRecorder"  android:layout_width="fill_parent"  android:layout_height="wrap_content"  android:text="录音"/></LinearLayout></ScrollView>
