Waterfall flow, pull down refresh, pull up load more

Foreword: Because the project needs, the manager calls me to do a waterfall flow view, has looked for several current mainstream waterfall flow solution on the net. Finally, the respective solutions were studied, and I chose the stageredgridview. We can find it on the GitHub. But in the end, I found that it is inconvenient to use Stageredgridview to pull down and load more, and Stageredgridview is not perfect in many functions. After thinking over and over, I still found a breakthrough in the Stageredgridview.

Goal: As a result of Drop-down refresh, pull load more, online has been a lot of related solutions, I studied these solutions, found a common ground, are in the ListView, the GridView, ScrollView on the deal. Including the current GitHub on a project called Pulltorefresh, can be used directly in ListView, GridView, ScrollView, in the Stageredgridview is not applicable. Think for a moment, if you can do a control like this, arbitrary view (such as: LinearLayout,) placed in it, can be very convenient to achieve this function, that should be much better. I think a set of solutions, I hope that we can discuss, advice.

Solution: In a relativelayout, put 5 layouts first (of course it can be arbitrary, I choose linearlayout). As shown in the following illustration:

Under such a scheme, I tested the stageredgridview,srcollview separately. can achieve the desired effect, because the project is not too tight to test other views, this is what I took out the purpose of discussion, I hope that we can improve together.

Instance effect: Below is my test Stageredgridview's effect.
