我想创建一个包含4个元素的mapview标记: - 图片(用户) - 背景 - 文字(用户名) - 箭头显示方向
OverlayItem.setMarker()只接受一个drawable。
如何创建包含4个项目的drawable?或者我可以将一个视图作为标记添加到overlayItem?
任何想法?

我找到了解决方案。 我创建了一个BitmapDrawable
这是代码
Bitmap photo = ((BitmapDrawable)mActivity.getResources().getDrawable(R.drawable.user_picture_dummy)).getBitmap();
Bitmap returnedBitmap = Bitmap.createBitmap(Global.dipToPx(40), Global.dipToPx(67), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(returnedBitmap);
mBackground.setBounds(0, Global.dipToPx(10), canvas.getWidth(), canvas.getHeight());
mBackground.draw(canvas);
m.postScale((float)Global.dipToPx(30)/(float)photo.getWidth(), (float)Global.dipToPx(30)/(float)photo.getHeight());
m.postTranslate(Global.dipToPx(5), Global.dipToPx(15));
canvas.drawBitmap(photo, m, paint);
m.reset();
canvas.drawText(Global.DateToTimeString(adv.getStartDateMS()), Global.dipToPx(20), Global.dipToPx(10), paint);
mat.postRotate((float)bearingTo(adv.getDepGeoPoint(), adv.getArrLocationObj().getGeoPoint()), mDirection.getWidth()/2, mDirection.getHeight()/2);
mat.postTranslate(canvas.getWidth()-mDirection.getWidth(), canvas.getHeight()-mDirection.getHeight()-Global.dipToPx(12));
canvas.drawBitmap(mDirection, mat, paint);
mat.reset();
BitmapDrawable drawable = new BitmapDrawable(returnedBitmap);
boundCenter(drawable);
OverlayItem item = new OverlayItem(adv.getDepGeoPoint(), adv.getOwnerObj().getUserName(), adv.getOwnerObj().getUserName());
item.setMarker(drawable);
