我正在尝试在放置为res/drawable/schoolboard.png
. 图像填充活动背景。以下不起作用:
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.schoolboard);
Paint paint = new Paint();
paint.setAntiAlias(true);
paint.setColor(Color.BLUE);
Canvas canvas = new Canvas(bitmap);
canvas.drawCircle(60, 50, 25, paint);
ImageView imageView = (ImageView)findViewById(R.drawable.schoolboard);
imageView.setAdjustViewBounds(true);
imageView.setImageBitmap(bitmap);
任何帮助将不胜感激。谢谢。
