android - How to Programmatically Add Views to Views -


let's have linearlayout, , want add view it, in program java code. method used this? i'm not asking how it's done in xml, know, rather, how can along lines of this?

(one view).add(another view)

like 1 can in swing.

calling addview correct answer, need little more work.

if create view via constructor (e.g., button mybutton = new button();), you'll need call setlayoutparams on newly constructed view, passing in instance of parent view's layoutparams inner class, before add newly constructed child parent view.

for example, might have following code in oncreate() function assuming linearlayout has id r.id.main:

linearlayout mylayout = findviewbyid(r.id.main);  button mybutton = new button(this); mybutton.setlayoutparams(new linearlayout.layoutparams(                                      linearlayout.layoutparams.match_parent,                                      linearlayout.layoutparams.match_parent));  mylayout.addview(mybutton);

making sure set layoutparams important. every view needs @ least layout_width , layout_height parameter. getting right inner class important. struggled getting views added tablerow display until figured out wasn't passing instance of tablerow.layoutparams child view's setlayoutparams.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
