dynamic

问题 I have a homework assignment. I'm not looking for anyone to do the work for me, I'm just having trouble with one little aspect, although I'd accept advice on other bits as well. The assignment is: Write a class using a two-dimensional dynamic array. The constructor passes in the dimensions of the array. The constructor also intializes all values in the dynamic array to the row index multiplied by the column index. Swap two columns of the two-dimensional array, where the column indexes are

问题 I have 10 TextViews in my code and i would like to change font size on all of them. On my layout i have used a @style to define common properties however i don't know how to change them all from code once layout is on screen. What i dont want to do is update N objects but write only in one place.

问题 I have a layout where users can add buttons and place them where they want. I want to allow the user to save their layout so that it is loaded the next time they open the app. Does anyone know if I can save the file on the sdcard? Alternatively I could use some kind of layout.getXml() method and put it in the database my app uses. Thanks in advance 回答1: There is no file to save when you are generating a layout via code.

问题 I'm struggling to find a way to map some JSON into RestKit.
