  1. POGLSurfaceView continuously renders despite changing render mode
    text
    copied!<p>I'm trying to create a GLSurfaceView that displays a map of a game area. When the player moves, the game activity calls highlightSpot, which in turn should trigger a render request. The only time I want to re-draw the view is when the player moves.</p> <p>However, with my current implementation, despite calling <code>setRenderMode(RENDERMODE_WHEN_DIRTY)</code> on my GLSurfaceView, its render mode still seems to be continuous. To check, I threw a single println statement in my onDrawFrame method, and when I run my application, the output quickly fills up my logcat without the player moving even once-- it's clearly not behaving as I intended. Is there something else I need to do in order to make the view render only when asked?</p> <p>(The bulk of this code is derived from the tutorials at <a href="http://insanitydesign.com/wp/projects/nehe-android-ports/" rel="noreferrer">http://insanitydesign.com/wp/projects/nehe-android-ports/</a>. I omitted my onDrawFrame, OnSurfaceChanged, and onSurfaceCreated methods for the sake of conciseness, as I am not changing the render mode or requesting a render anywhere in those methods. If someone thinks it might be relevant, I can post those too.)</p> <pre><code>public class SurfaceViewClass extends GLSurfaceView implements Renderer { public SurfaceViewClass(Context context) { super(context); ... this.setRenderer(this); this.setRenderMode(RENDERMODE_WHEN_DIRTY); } public void highlightSpot(int x, int y) { /* change some variables here */ ... this.requestRender(); } } </code></pre>
