Question

I actually work on an Game and need some backup because Canvas.

I draw a background with canvas. So i made Picture exactly for the resolution of the screen we work on. On the device the picture is to small and dont fitt to the screen. Did i miss something that the draw makes it smaller?

Here is some code

public class Map extends View{
int[][] mapArray = new int[32][18];
private Bitmap picture;
private Paint paint;

public Map(Context context){
    //basic init map
    super(context);

    this.setPicture(BitmapFactory.decodeResource(context.getResources(), R.drawable.newmap2));
}


public Bitmap getPicture() {
    return picture;
}

public void setPicture(Bitmap background) {
    this.picture = background;
}

@Override
protected void onDraw(Canvas canvas) {
    canvas.drawBitmap(picture, 0, 0, paint);
}

Hope you can help me out
Best regards
Ben

Answer 1

Maybe you put the bitmap in a high dpi directory (e.g. res/drawable-xhdpi) and your device is of a lower dpi ? In this case the image is scaled down on open.
What you are doing is not safe, other devices will have other screen sizes.
