*/
public class TestSeekBar extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
this.setContentView(R.layout.main);
}

}

方法一:

-----------------------

main.xml

style="?android:attr/progressBarStyleHorizontal"
android:layout_width="fill_parent"
android:layout_height="23dip"
android:paddingLeft="25dip"
android:paddingRight="25dip"
android:paddingBottom="4dip"

android:progressDrawable="@drawable/seekbar_style"
android:thumb="@drawable/thumb" />

---------------------------------------

android:state_pressed="true"
android:drawable="@drawable/thumb_bt_pressed" />

android:state_focused="false"
android:state_pressed="false"
android:drawable="@drawable/thumb_bt" />

----------------------------------------------

android:startColor="#ffffffff"
android:centerColor="#ff000000"
android:endColor="#ff808A87"
android:centerY="0.45"
android:angle="270"/>

android:startColor="#ffffffff"
android:centerColor="#ffFFFF00"
android:endColor="#ffAABD00"
android:centerY="0.45"
android:angle="270"/>

方法二:

android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:max="20"
android:progress="0"
android:secondaryProgress="0"
android:paddingLeft="32px"
android:paddingRight="32px"
android:progressDrawable="@drawable/seekbar_img"
android:thumb="@drawable/thumb"
/>

-------------------------------------------------------------

xmlns:android="http://schemas.android.com/apk/res/android "
>

android:id="@+android:id/background"
android:drawable="@drawable/seekbar_bg" />

android:id="@+android:id/SecondaryProgress"
android:drawable="@drawable/seekbar_rawbcon" />

android:id="@+android:id/progress"
android:drawable="@drawable/progress_cookedbacon" />

----------------------------------

android:state_pressed="true"
