  1. POAndroid Drawable looks ugly due to scaling
    text
    copied!<p>I am writing a View that should show a drawable that seems to "never end". It should be twice or third the displaysize and move slow through the display.</p> <p>Therefore I studied some samplecode by Google and found the important Lines</p> <pre><code>public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) { canvasWidth = width; canvasHeight = height; float sf = backgroundImage.getWidth() / canvasWidth; backgroundImage = Bitmap.createScaledBitmap(backgroundImage, (int) (canvasWidth * sf), canvasHeight, true); } </code></pre> <p>To rescale the image and than</p> <pre><code> // decrement the far background backgroundXPos = backgroundXPos - DELTAMOVE; // calculate the wrap factor for matching image draw int newFarX = backgroundImage.getWidth() - (-backgroundXPos); // if we have scrolled all the way, reset to start if (newFarX &lt;= 0) { backgroundXPos = 0; // only need one draw canvas.drawBitmap(backgroundImage, backgroundXPos, 0, null); } else { // need to draw original and wrap canvas.drawBitmap(backgroundImage, backgroundXPos, 0, null); canvas.drawBitmap(backgroundImage, newFarX, 0, null); } </code></pre> <p>To draw the moving image. The images is already moving, it's fine.</p> <p>But, and this is the point of my question, the image looks very ugly. Its original is 960*190 pixels by 240ppi. It should be drawn inside a view with 80dip of height and "fill_parent" width.</p> <p>It should look same (and good) on all devices. I have tried a lot but I don't know how to make the picture look nice.</p> <p>Thanks for your help. Best regards, Till</p>
