二，main.xml 源碼

<?xml version="1.0" encoding="utf-8"?><LinearLayout  xmlns:android="http://schemas.android.com/apk/res/android"  android:background="@drawable/white"  android:orientation="vertical"  android:layout_width="fill_parent"  android:layout_height="fill_parent">  <TextView    android:id="@+id/myTextView1"    android:layout_width="fill_parent"     android:layout_height="wrap_content"    android:textColor="@drawable/blue"     android:text="@string/hello"  />  <SurfaceView    android:id="@+id/mSurfaceView1"     android:layout_width="100px"     android:layout_height="100px">   </SurfaceView>    <SeekBar android:id="@+id/seekBar" android:layout_height="wrap_content" android:layout_width="fill_parent" />       <LinearLayout     android:orientation="horizontal"     android:layout_height="wrap_content"     android:layout_width="fill_parent"     android:padding="10dip"   >  <ImageButton android:id="@+id/play"     android:layout_height="wrap_content"     android:layout_width="wrap_content"    android:src="@drawable/play"  />   <ImageButton android:id="@+id/pause"    android:layout_height="wrap_content"     android:layout_width="wrap_content"     android:src="@drawable/pause"  />   <ImageButton android:id="@+id/reset"     android:layout_height="wrap_content"     android:layout_width="wrap_content"     android:src="@drawable/reset"  />   <ImageButton android:id="@+id/stop"     android:layout_height="wrap_content"     android:layout_width="wrap_content"     android:src="@drawable/stop"  />   </LinearLayout> </LinearLayout>

三，源碼中所需其餘圖片等 ，自備就可以。經測試通過可以播放，前提需要sdcard中已經傳入播放檔案
