Android:如何将整个 ImageView 转换为位图? [英] Android: how to convert whole ImageView to Bitmap?

问题描述

我的应用程序以不同的比例显示图像，并在内部(centerInside)imageView 调整大小.我需要的是从 ImageView 创建位图，包括背景(在这种情况下为黑色).

I have my application that is displaying images with different ratio, resized inside (centerInside) imageView. What I need is to create bitmap from the ImageView including the background (black in this case).

例如，我有 320x480 的设备屏幕，全屏 imageView，图像大小调整为 280x480.我怎样才能从中获得 320x480 位图?

So for example I have device screen 320x480, full screen imageView with image resized to 280x480. How could I get 320x480 bitmap from it?

在此图像视图之上，我有一些我不想包含在位图中的徽标或按钮，它们就像在顶层一样.我所需要的只是一些带有图像和黑色边框的位图.

On top of this imageview I have some logos or buttons that I don't want to include to bitmap, they're like on top layer. All I need is bitmap with image and black border from some sides.
