传递你的ImageView，根据屏幕的高度和宽度，你可以做出它

    public void setScaleImage(EventAssetValueListenerView view){
        // Get the ImageView and its bitmap
        Drawable drawing = view.getDrawable();
        Bitmap bitmap = ((BitmapDrawable)drawing).getBitmap();
        // Get current dimensions
        int width = bitmap.getWidth();
        int height = bitmap.getHeight();

        float xScale = ((float) 4) / width;
        float yScale = ((float) 4) / height;
        float scale = (xScale <= yScale) ? xScale : yScale;

        Matrix matrix = new Matrix();
        matrix.postScale(scale, scale);

        Bitmap scaledBitmap = Bitmap.createBitmap(bitmap, 0, 0, width, height, matrix, true);
        BitmapDrawable result = new BitmapDrawable(scaledBitmap);
        width = scaledBitmap.getWidth();
        height = scaledBitmap.getHeight();

        view.setImageDrawable(result);

        LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) view.getLayoutParams();
        params.width = width;
        params.height = height;
        view.setLayoutParams(params);
    }

以编程方式应用宽高比到Imageview:

aspectRatio = imageWidth/imageHeight   
ratioOfWidth = imageWidth/maxWidth  
ratioOfHeight = imageHeight/maxHeight  


if(ratioOfWidth > ratioOfHeight){​​​​​​​
    imageWidth = maxWidth 
    imageHeight = imageWidth/aspectRatio
}​​​​​​​ else if(ratioOfHeight > ratioOfWidth){​​​​​​​
    imageHeight = maxHeight
    imageWidth = imageHeight * aspectRatio
}​​​​​​​

之后，您可以使用缩放位图图像视图

Bitmap scaledBitmap= Bitmap.createScaledBitmap(bitmap, (int) imageWidth , (int) imageHeight , true);

imageView.setImageBitmap(Bitmap.createScaledBitmap(bitmap, 130, 110, false));

在使用cardviewfor舍入imageview和固定的android:layout_height为标题的情况下，这对我来说是有效的，用Glide加载图像

    <?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
             xmlns:tools="http://schemas.android.com/tools"
             android:layout_width="match_parent"
             android:layout_height="220dp"
             xmlns:card_view="http://schemas.android.com/apk/res-auto"
             >

    <android.support.v7.widget.CardView
            android:id="@+id/card_view"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center|top"
            card_view:cardBackgroundColor="@color/colorPrimary"
            card_view:cardCornerRadius="10dp"
            card_view:cardElevation="10dp"
            card_view:cardPreventCornerOverlap="false"
            card_view:cardUseCompatPadding="true">

        <ImageView
                android:adjustViewBounds="true"
                android:maxHeight="220dp"
                android:id="@+id/iv_full"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:scaleType="fitCenter"/>

    </android.support.v7.widget.CardView>
</FrameLayout>

如果你想让你的图像占据尽可能大的空间，那么最好的选择是

android:layout_weight="1"
android:scaleType="fitCenter"

这解决了我的问题

android:adjustViewBounds="true"
android:scaleType="fitXY"
