android - 如何显示位图资源与使用形状绘制命令？

Question

如何将我的位图从 drawCircle 更改为可绘制的导入图像？

我有这个代码:

canvas.drawCircle((currentX * totalCellWidth)+(cellWidth/2),
    (currentY * totalCellHeight)+(cellWidth/2),
    (cellWidth*0.45f),ball);

...产生此输出:

我尝试通过此更改来替换圆的位图资源:

Bitmap b = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);

canvas.drawBitmap(b, (currentX * totalCellWidth)+(cellWidth/2),
        (currentY * totalCellHeight)+(cellWidth/2),
        ball);

...但它似乎不起作用。

Answer 1

如果您尝试更改位图的大小。

Bitmap b = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);

// assign value for the new target size
int newsizeX = width;
int newsizeY = height;

resizedbitmap = Bitmap.createScaledBitmap(resizedbitmap, width, height, true);

canvas.drawBitmap(resizedbitmap, *location in X*, *location in Y*, paint);

它应该工作得很好:)
