我在横幅(高度 48dp)和页脚(48dp)之间创建了一个带有可滚动图像的 RelativeLayout。在分辨率为 320 x 480 的手机布局上加载尺寸为 767 X 1105 的图像时,图像宽度适合设备宽度,但图像的高度会被拉伸,这会干扰纵横比。请提出解决方案。
下面是布局xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/p_1_prastavana_1"
android:orientation="vertical" >
<include
android:id="@+id/banner1"
android:layout_alignParentTop="true"
layout="@layout/topheadings" />
<LinearLayout
android:id="@+id/footer1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:orientation="vertical" >
<include layout="@layout/footer" />
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_above="@id/footer1"
android:layout_below="@id/banner1" >
<ScrollView
android:id="@+id/scroll1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:fillViewport="false"
android:orientation="vertical" >
<ImageSwitcher
android:id="@+id/content_image"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:scaleType="centerCrop"
android:src="@drawable/p_1_prastavana_1" >
</ImageSwitcher>
</ScrollView>
</LinearLayout>
</RelativeLayout>
