我正在开发一个积木游戏这里是代码

paint.setColor(Color.BLACK);
for (int i = 0; i < no_bricksperline; ++i)

问题是砖正在显示
当我直接使用砖图像时，它们会被像素化，并且只显示 2 块砖。所以我写了一个逻辑来显示最少的砖块
我在我的代码中使用了一些逻辑这里是代码
String strwidth=String.valueOf(((float)(bmp.getWidth())/NO_COLUMNS));
if(strwidth.contains("."))
{
scalebit=Bitmap.createScaledBitmap(bmp, (int)(Math.ceil(((float)bmp.getWidth())/NO_COLUMNS))*NO_COLUMNS, bmp.getHeight(), true);
}
else
{
scalebit=bmp;
}
但是墙和砖之间有一个缝隙。我怎样才能让砖块占据整个屏幕。
