生成图片的操作比较耗时,虽然是View对象,但咱是直接把View对象转成图片,不涉及修改UI显示,可以异步处理。
contentLayout.setDrawingCacheEnabled(true); contentLayout.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED), MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED)); contentLayout.layout(0, 0, contentLayout.getMeasuredWidth(), contentLayout.getMeasuredHeight()); contentLayout.buildDrawingCache(); Bitmap bitmap= contentLayout.getDrawingCache();
