Android 2.1 View s getDrawingCache() method always returns null
我欢呼我想要挽救的一点图。
如果我的拉伊特人少于屏幕,那么一切都是罚款的。 但是,如果我的距离更大,则标的(b)是无效的。
这是我的法典:
layout.setDrawingCacheEnabled(true);

int ht = layout.getMeasuredHeight();
layout.layout(0, 0, wt, ht);
Bitmap b = layout.getDrawingCache(true);
因此,我如何能够把整个观点当作一个比喻?
