Android Webview仅从页面顶部获取屏幕截图 [英] Android webview takes screenshot only from top of the page

问题描述

我正在做一个非常简单的任务，将我的webView的屏幕截图捕获到位图中……我这样做是这样的:

I am doing a very simple task of taking a screenshot from my webView into a Bitmap... I do it like this:

webView.setDrawingCacheEnabled(true);
Bitmap bitmap = Bitmap.createBitmap(webView.getDrawingCache(false));
webView.setDrawingCacheEnabled(false);
Canvas canvas = new Canvas(bitmap);
webView.draw(canvas);

问题在于最终的位图总是显示我网页内容的顶部！我实际上需要它来从滚动内容的地方截取屏幕截图，但这不是简单的事情！我已经在网上搜索了两个小时，但是似乎没有其他人遇到类似的问题.知道可能出了什么问题吗?

The problem is that the final bitmap is always showing the top of my web page content! I actually need it to take the screenshot from where I have scrolled the content but this is not simply happening! I have been searching the net for two hours now but no one else seems to have a similar problem. any idea what could have gone wrong?

推荐答案

我猜是在棒棒糖上吗?如果是这样，请确保调用WebView.enableSlowWholeDocumentDraw()( doc )，则在首次调用setContentView()时，该调用会使用WebView扩大布局.

I guess, this is on Lollipop? If so, make sure you call WebView.enableSlowWholeDocumentDraw() (doc) before your first call to setContentView() that inflates a layout with WebView.
