如何在Android中将图像调整为imageview高度？

Question

我想做一些图像查看器（sorta）应用程序，我正在使用viewpager在图像之间导航。图像的尺寸均为1260x2038，位于res / drawables目录中。我想做什么：

1. 在纵向模式下，图像将适合设备高度
2. 在横向模式下，图像将适合设备宽度并可垂直滚动。

因为我知道大图像会导致内存不足异常，所以我将其设置为如果设备高度大于或等于1920px，我想将最大高度成像为1920px。

我尝试将imageview放在一个滚动视图中，以使这些工作起作用，并且它们的工作方式不像我预期的那样。

这就是我的代码目前的相关部分，

fragment_page.xml

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ScrollView
        android:id="@+id/scroll"
        android:layout_width="wrap_content"
        android:layout_height="match_parent">

        <ImageView
            android:id="@+id/image"
            android:layout_width="wrap_content"
            android:layout_height="match_parent" />

    </ScrollView>
</LinearLayout>

FragmentPage.java

public class PageFragment extends Fragment
{
    private ScrollView scroll;
    private ImageView image;
    private int imageId;
    private int deviceWidth,deviceHeight;
    private static double ratio = 0.61825;

    private static LinearLayout.LayoutParams scrollPortraitParams   = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.MATCH_PARENT);

    private static ScrollView.LayoutParams imagePortraitParams      = new ScrollView.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.MATCH_PARENT);

        {
            scroll.setLayoutParams(scrollPortraitParams);
            image.setLayoutParams(imagePortraitParams);

            if(deviceHeight >= 1920)
            {
                Glide.with(getActivity())
                     .load(imageId)
                     .override(1187, 1920)
                     .fitCenter()
                     .into(image);
            }
            else

            }
        }
        else

            if(deviceWidth >= 1920)
            {
                scroll.setLayoutParams(scrollLandscapeParams);
                image.setLayoutParams(imageLandscapeParams);
                Glide.with(getActivity())
                     .load(imageId)
                     .override(1187, 1920)
                     .fitCenter()
                     .into(image);
            }
            else
            {
                scroll.setLayoutParams(scrollLandscapeParams);
                image.setLayoutParams(imageLandscapeParams);
                Glide.with(getActivity())
                     .load(imageId)
                     .override(deviceWidth, (int)(deviceWidth * ratio2))
                     .fitCenter()
                     .into(image);
            }

非常感谢任何帮助。感谢。
