POHow continue updating screen without flooding onTouchEvent ? (android SurfaceView)
text
Body
copied!<p>When you have a surfaceView class, used for animation/game/... you have the onTouchEvent() method and the drawing/screen-refreshing method in that same class. Now I want to just sleep the onTouchEvent method, so it doesn't get called +-80 times a second and flooding the cpu (and therefor causing lag). The problem is that if I sleep this class, it also stops drawing/updating/refreshing. What could be a good solution for this?</p> <p><strong>Edit</strong><br> @tanner, that's indeed what i'm trying, to stop onTouchEvent() to be called too frequently. my attempt: </p> <pre><code>@Override public boolean onTouchEvent(MotionEvent event) { Log.d("firstTest",Integer.toString(event.getAction())); //shows up if (!sleeper.CurrentlySleeping) { Log.d("2ndTest",Integer.toString(event.getAction())); //not showing up ~~ some calculations and stuff ~~ </code></pre> <p>. </p> <pre><code>public class TouchSleeper extends Thread { // If Thread is sleeping or not. public static Boolean CurrentlySleeping; public TouchSleeper() { CurrentlySleeping = false; this.setPriority(MIN_PRIORITY); } @Override public void run() { try { while (true) { CurrentlySleeping = true; TouchSleeper.sleep(50); CurrentlySleeping = false; } ~end~ </code></pre> <p>First a piece of code from my SurfaceView class. Second piece of a class/thread, wich keeps changing a boolean value. Note how my first Log.d does return something, and the second one doesn't. This tells me that CurrentlySleeping is never false ? I still have not figured things out... ?</p>
