It was also ireader to achieve the effect of the bookshelf, but that was implemented using ListView, which was not easy to use. Most of them are implemented with the GridView, the online data is relatively small, some open source of e-books are focused on reading, and did not like Ireader and QQ to read the Bookshelf effect.

To give N and b, and then give n number, with this n number of some, to find a and, this and is the minimum value of >=b, the output of the minimum and B difference.
Analysis: This problem is very simple, is very obvious 01 knapsack problem, here n items, the weight of each item is C[i], value is w[i] and c[i]==w[i],, capacity for all C[i] and sum. Just start from scratch in f[] and find a minimal >=b is the solution to the problem

In fact, the bookshelf works well. You only need to calculate the location rectangle of the bookshelf in the ondraw () method of the custom gridview, and then the draw will be OK. I personally think it is relatively simple.
The Code is as follows:
Public class playbackfocusedgridview extends focusedgridview {Drawable minterlayer = This. getresources (). getdrawable (R. drawable. TV _playback_shelf); //
