我希望父视图设置ImageView的宽度,高度应该是高宽比例.原因是next会显示一个我想放在ImageView下面的TextView.
我可以使用正确显示图像
android:layout_width="fill_parent"
android:layout_height="fill_parent"

但是ImageView高度变为父高度,远远大于显示的拉伸图像的高度.一个想法是让父母垂直变小,但是......我还不知道拉伸的图像大小.
以下操作无效,因为水平未填充小图像.
android:layout_width="fill_parent"
android:layout_height="wrap_content"

对于它周围的RelativeLayout一切都没有帮助.还尝试了FrameLayout和LinearLayout并失败了.
有任何想法吗?
我正在学习如何使用OpenCV编写C++代码,我想在Android中运行它.我使用Android Studio.
我创建了一个支持C++的新简单项目,然后我将测试代码添加到C++文件中.看来,我自己的文件编译和链接.
现在,我认为与我的项目无关的其他因素导致许多错误.它似乎是NDK内部的东西.它可能是最新版本中的错误,如果是这样,我该怎么办呢?
