作为我的pic,搜索栏进度= 0,但搜索栏拇指中心不在起点.我的代码:

   <SeekBar  android:layout_width="match_parent"
                 android:layout_height="wrap_content"
                 android:progressDrawable="@drawable/seekbar_progress"
                 android:thumb="@drawable/seekbarthumb"
                 android:minHeight="10dip"
                 android:maxHeight="10dip"
                 android:thumbOffset="0px"
                 android:max="100"
                 android:id="@+id/bright_seekbar"
                 android:layout_marginLeft="60dip"/>
