问题描述

所以我用

android:maxHeight="100px"
android:maxWidth="250px"
android:minHeight="100px"
android:minWidth="250px"
android:scaleType="centerInside"

此图像视图用于显示从图库或相机中获取的图片.在这两种情况下，图像都不会调整大小以适应 imageview，它只是根据需要拉伸其空间.

This image view is used to show a picture that is obtained from the gallery or camera. In both cases, the image is not resized to fit inside the imageview, it just stretches its space as much as it needs.

知道如何让它保持在这些范围内吗?

Any idea how to make it stay inside those bounds?

推荐答案

试试 adjustViewBounds 属性:

Try the adjustViewBounds attribute:

android:adjustViewBounds="true"
