i implementing simple render view class android extending surfaceview. main activity class includes infinite while loop other operations. however, app shows black screen when main activity in infinite loop. far know, main activity , surface view classes have own separate threads, surface view class should keep rendering when main activity class busy. app works fine when prevent infinite loop setting 'running' boolean variable false in code. what might reason of surface view class stops rendering when main activity in infinite loop? my main activity , surface view classes follows: import android.app.activity; import android.os.bundle; import android.view.window; import android.view.windowmanager; public class mainactivity extends activity{ rendersurfaceview renderview; public boolean running = true; @override protected void oncreate(bundle savedinstancestate) { super.oncreate ( savedinstancestate ); requestwindowfeature(window.featu

i developing application aimed render huge number of shapes. each shape can assigned specific layer . i input data list of shapes, each shape have string property represents layer shape belongs. now, need develop method allows me select (draw) shapes belong given list of selected layers. in pseudo-code: void draw_if(sorted_list shapes, list<string> selected_layers) { each shape in shapes { if (shape.layer in selected_layers) shape.draw(); } } the point perform operation fast possible; therefore need choose right data structures , proper algorithm. the list of selected layers list of strings (1÷100 different layers), if needed performance reasons, converted other data types. the shapes sorted according z-order. basic intrusive solutions overlooked here in search of elaborate data structures , algorithms, fastest. assuming have no choice keep selection separate, if want fast solution, store boolean selection flag in each layer (co

i want make app has timer starting @ 10.0000000 example, , want countdown here's code far: import uikit class viewcontroller: uiviewcontroller { @iboutlet weak var labeltime: uilabel! var counter = 10.0000000 var labelvalue: double { { return nsnumberformatter().numberfromstring(labeltime.text!)!.doublevalue } set { labeltime.text = "\(newvalue)" } } override func viewdidload() { super.viewdidload() // additional setup after loading view, typically nib. labelvalue = counter var timer = nstimer.scheduledtimerwithtimeinterval(0.0000001, target: self, selector: ("update"), userinfo: nil, repeats: true) } func update(){ labelvalue -= 0.0000001 } } what happens countdown slow, it's not working , take 1 hour 0 seconds, instead of 10 seconds. ideas? changes should make code? thanks timers not super-accurate, , res
