**** <public type="drawable" name="ic_volume_ringer" id="0x7f020XXX" />
**** <public type="drawable" name="ic_volume_system" id="0x7f020XXX" />
下一步需要重新定义smali里的id，将原来smali里的id，替换成你的id！
8. 打开 smali/com/b16h22/MediaVolumeSlider.smali
*** 找到 0x7f0200b6 —— ic_volume_media replace with hex code themselves (0x7f020XXX)
9. 打开 smali/com/b16h22/NotificationVolumeSlider.smali
*** 找到 0x7f0200b7 —— ic_volume_notif (0x7f020XXX)
10. 打开 smali/com/b16h22/RingerVolumeSlider.smali
*** 找到 0x7f0200b8 —— ic_volume_ringer (0x7f020XXX)
11. 打开 smali/com/b16h22/SystemVolumeSlider.smali
*** 找到 0x7f0200b9 —— ic_volume_system (0x7f020XXX)
——表示将前面的 0x7f020xxx 替换成后面代码的public.xml里的id
12. 保存并回编译

应该可以看到吧。。
