可以用自定义的图片来标记progressbar进度的特殊progressbar

效果图

• 在xml中像官方Progressbar一样使用,并设置自己喜欢的风格

   <com.clj.imageprogressbar.ImageProgressBar
   android:id="@+id/progressbar1"
   android:layout_width="match_parent"
   android:layout_height="30dp"
   android:layout_gravity="center_horizontal"
   android:background="@android:color/holo_blue_dark"
   android:paddingLeft="2dp"
   android:paddingRight="2dp"
   custom:progress_current="0"
   custom:progress_image_id="@mipmap/ic_car"
   custom:progress_image_offset="5dp"
   custom:progress_image_proportion="1.1"
   custom:progress_max="100"
   custom:progress_reached_bar_height="2dp"
   custom:progress_reached_color="@color/colorAccent"
   custom:progress_unreached_bar_height="2dp"
   custom:progress_unreached_color="@color/colorPrimary" />
