Android SurfaceView slows if no touch events occur

阅读更多关于 Android SurfaceView slows if no touch events occur

问题 I am making a game and all is going well except for the game loop. I am using a SurfaceView and drawing 2D Sprites (Bitmaps). Currently the game is a ship moving through an asteroid field. The ship stays in the center of the screen and the phone is tilted in either direction to move the the asteroids (asteroids change location instead of player). New asteroids spawn as old ones fall off the screen creating an infinite asteroid field feeling. Running on my Nexus 5, I noticed that after about 3

Android - onStop() will be called with a delay

阅读更多关于 Android - onStop() will be called with a delay

I found my activities onStop() method will be called with a less than 10 seconds delay. I've never seen before this behavior. Note :- The activity is singleTop and it starts with Intent.FLAG_ACTIVITY_REORDER_TO_FRONT flag. Note :- I'm using Build Tools v23.0.2. The delay wasn't before and the method would be called immediately. I am guessing that you are starting another activity and you expect the current activity to receive an onStop() callback. According to the activity lifecycle , the onPause() method is called before the onStop(). In some cases onSaveInstance() is also called before the

ListView scroll lagging when images is shown?

阅读更多关于 ListView scroll lagging when images is shown?

My listview lags when scrolling. It seems as the lazyload works but the lag happens everytime an image is shown. I'm using the imageLoader found here http://www.androidhive.info/2012/02/android-custom-listview-with-image-and-text/ and this is my adapter: public class EventAdapter extends ArrayAdapter<Event>{ public ListImageLoader imageLoader; public DisplayImageOptions imgDispOpts; private ArrayList<Event> objects; public EventAdapter(Context context, int textViewResourceId, ArrayList<Event> objects,ListImageLoader imageLoader) { super(context, textViewResourceId, objects); this.objects =

decreasing sifr render time

阅读更多关于 decreasing sifr render time

I'm using sifr for a few items on this page: http://blueprint.staging.dante-studios.com/public/templates/home.php unfortunately it seems that the rendering is very slow, does anyone have any idea of how to: a) speed up the rendering process b) hide all "to be sifr'd" items until all of them are ready? Here are a few suggestions: The Flash movie has the bold and italic and bold + italic glyphs embedded. If you don't need those, they're adding needless weight to the movie. Same goes for other characters. You could get rid of all JavaScript comments in the sifr-config file. Flash transparency is

ListView scrolling using UniversalImageDownloader not smooth

阅读更多关于 ListView scrolling using UniversalImageDownloader not smooth

问题 I am using a ListView containing images. These images are loaded from the Internet inside the adapter. Therefore I am using the UniversalImageDownloader . Unfortunately the scrolling of the ListView "lags" for a short time as soon as I scroll down where new content has to be downloaded. I acutally expected behaviour like the ListView scrolls perfectly smooth, but the loading of the Image can of course take some more time - which should not effect the smoothness of scrolling. Furthermore, as I

阅读更多关于 R plm lag - what is the equivalent to L1.x in Stata?

问题 Using the plm package in R to fit a fixed-effects model, what is the correct syntax to add a lagged variable to the model? Similar to the 'L1.variable' command in Stata. Here is my attempt adding a lagged variable (this is a test model and it might not make sense): library(foreign) nlswork <- read.dta("http://www.stata-press.com/data/r11/nlswork.dta") pnlswork <- plm.data(nlswork, c('idcode', 'year')) ffe <- plm(ln_wage ~ ttl_exp+lag(wks_work,1) , model = 'within' , data = nlswork) summary

I have the following code to add a border colour and drop shadow to the background of my UITableViewCell. My problem is that this code causes a huge lag on the tableView itself.
