Question

我有两个图像视图：

<ImageView
    android:id="@+id/logo"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:visibility="visible"
    android:src="@drawable/ic_logo"/>


<ImageView
    android:id="@+id/logo_small"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:visibility="invisible"
    android:scaleType="centerCrop"
    android:src="@drawable/ic_logo_small"/>

logo_small只是徽标的大小调整版本（宽度和高度已调整为75％）。我注意到logo.getGlobalVisibleRect（logoRect）返回不同宽高比的尺寸，与logo_small.getGlobalVisibleRect（logoSmallRect）相比。为什么会这样？编辑：根据要求，这里有更多代码：

 final ImageView logo = (ImageView) findViewById(R.id.logo);
 final ImageView logo_small = (ImageView) findViewById(R.id.logo_small);
 Rect logoRect = new Rect();
 Rect logoSmallRect = new Rect();
 logo.getGlobalVisibleRect(logoRect);
 logo_small.getGlobalVisibleRect(logoSmallRect);
 Log.d("LOGO", "logo aspect ratio " + ((float)logoRect.width()/ logoRect.height()) + ", logo_small aspect ratio " + ((float)logoSmallRect.width()/ logoSmallRect.height()));

我得到的是：

 D/LOGO﹕ logo aspect ratio 1.0682492, logo_small aspect ratio 1.2081686

Android - 缩放和原始图像中不同的图像视图宽高比
