  1. POAndroid LinkedList lag when removing element
    text
    copied!<p>I really need help with this one. I am working with a game and have encountered a problem where it lags everytime an element is getting removed from my lists with objects. I have searched for solutions and found out about using iterators to reduce lag, but still, it lags. I have used both ArrayList and LinkedList, but they both end up with the same result.</p> <p>This is an example of the code I am using for my lists:</p> <p>Initialize:</p> <pre><code>private LinkedList&lt;Background&gt; bg = new LinkedList&lt;Background&gt;(); </code></pre> <p>Render:</p> <pre><code>for (Iterator&lt;Background&gt; iterator = bg.iterator(); iterator.hasNext();) { Background back = iterator.next(); if (back.getX()-(-width-1) &gt; 0) { if ((back.getX() &lt; width) || (back.getX()+width &gt; 0)) { back.draw(canvas); } else { iterator.remove(); } } } </code></pre> <p>This is the draw function inside the object class in which back.draw(canvas); is calling from:</p> <pre><code> public void draw(Canvas canvas) { // where to draw the sprite Rect destRect = new Rect(getX(), getY(), getX() + spriteWidth, getY() + spriteHeight); canvas.drawBitmap(bitmap, sourceRect, destRect, null); //canvas.drawBitmap(bitmap, 20, 150, null); //Paint paint = new Paint(); //paint.setARGB(50, 0, 255, 0); //canvas.drawRect(20 + (currentFrame * destRect.width()), 150, 20 + (currentFrame * destRect.width()) + destRect.width(), 150 + destRect.height(), paint); } </code></pre> <p>Maybe there is something that has to be changed in the MainThread that handles the FPS? Or is there any other solution? I have heard about sets, but can't seem to find any good example try it out.</p> <p>Something to point out is that I am using Canvas, not OpenGL. Something else to point out is that each element in the above array has an image size of 800x480. I have tried to reduce the quality of the image, but it doesn't make much of a difference.</p> <p>Thank you.</p>
