我创建了一个样本。这对我的作品。下面是XML布局文件。

I created a sample. It works for me. Here is the xml layout file.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <ImageView android:src="@drawable/hydrangeas"
        android:layout_height="wrap_content" android:id="@+id/imageView1"
        android:scaleType="centerInside"
        android:adjustViewBounds="true"
        android:background="@android:color/white"
        android:layout_width="wrap_content"/>

</LinearLayout>

它适用于 fitCenter 太。看一看快照。
