推荐答案

您可以用捕获的图像创建位图如下：

You can create bitmap with captured image as below:

Bitmap bitmap = Bitmap.createScaledBitmap(capturedImage, width, height, true);

在这里，您可以指定宽度要设置为您的ImageView位图和高度。的高度和宽度可以根据在装置的屏幕dpi的也设置，通过阅读不同设备的屏幕dpi的编程

Here you can specify width and height of the bitmap that you want to set to your ImageView. The height and width you can set according to the screen dpi of the device also, by reading the screen dpi of different devices programmatically.
