this is a draggable flow layout lib.
this is a draggable flow layout lib (android 可拖拽的流布局库) . support android-x Sample apk/示例app

//预存指定个数的Item. 这些Item会反复使用
mDragflowLayout.prepareItemsByCount(10);

i like technology. especially the open-source technology.And previous i didn't contribute to it caused by i am a little lazy, but now i really want to do some for the open-source. So i hope to share and communicate with the all of you.
