使用人行横道显示网页时，如何将整个视图捕获到位图中？ [英] How can I capture the whole view into a Bitmap when using crosswalk to display webpage?

问题描述

我使用CrossWalk显示网页，效果很好。我具有将全部内容捕获为位图以保存到SDCard的功能，但是找不到解决方案。使用TextureView只能捕获屏幕大小的位图，有人遇到同样的问题吗？顺便说一句，我可以使用WebView.draw（）捕获全部内容。

I use CrossWalk to display webpage, it works well. I have a feature to capture the whole content as bitmap to save into SDCard, but I cannot found a solution. Using TextureView can only capture a screen size bitmap, anyone has the same issue? BTW, I can capture the whole content using WebView.draw().

推荐答案

我以前从未使用过人行横道，但是我猜测Crosswalk WebView也是android.view.View的后代。如果是这样，那么您可以使用android视图绘图缓存。看起来像这样

I never using crosswalk before, but I'm guessing the Crosswalk WebView is also descendant from android.view.View. If so, then you could use android view drawing cache. It look like this

yourWebView.setDrawingCacheEnabled(true);
Bitmap bmp = yourWebView.getDrawingCache();

然后如Paul所说，通过FileOutputStream保存它

Then as Paul said, save it through FileOutputStream

bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos);
