下面是我行的项目布局

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal" android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/highlight_selector">

    <ImageView
        style="@style/imgPriceStoreLogoSmall"
        android:id="@+id/imgStoreLogo"
        android:src="@drawable/panda_logo"
        />
    <LinearLayout
        android:id="@+id/layoutPriceInfo"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:orientation="vertical" >
            <TextView
                android:id="@+id/lblStoreName"
                style="@style/lblRowProductName"
                android:layout_marginTop="5dp"
                android:textColor="@color/black"
                android:textSize="24sp"
                android:fontFamily="sans-serif-thin"
                android:text="Store Full Name"/>
            <TextView
                android:id="@+id/lblPrice"
                style="@style/lblRowOriginalPrice"
                android:textSize="20sp"
                android:textColor="@color/black"
                android:layout_marginTop="5dp"
                android:text="SAR 16.95"/>
        </LinearLayout>
    <ImageView style="@style/imgRowArrowIcon" />
</LinearLayout>

和我的风格

<style name="imgPriceStoreLogoSmall">
    <item name="android:layout_width">80dp</item>
    <item name="android:layout_height">80dp</item>
    <item name="android:layout_gravity">start</item>
    <item name="android:padding">5dp</item>
    <item name="android:scaleType">fitXY</item>
    <item name="android:contentDescription">@string/app_name</item>
    <item name="android:src">@drawable/no_image</item>
</style>

我不知道的标志图像的实际尺寸，但要调整到适合ImageView的很好。任何帮助是AP preciated。

I do not know the actual sizes of the logo images but want to resize to fit in imageview nicely. Any help is appreciated.

谢谢，

推荐答案

以下code适合图像yoursampleimage如果服务器的图像是如此之大。

The following code fits the image to yoursampleimage if the server image is so big

  <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@drawable/yousampleimagesizeimage" >

            <ImageView
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:layout_weight="1"
                android:adjustViewBounds="true"
                android:maxHeight="?android:attr/listPreferredItemHeight"
                android:maxWidth="?android:attr/listPreferredItemHeight"
                android:scaleType="centerCrop"
                android:src="@drawable/serverorDynamicimage" />
        </LinearLayout>

（或）

<RelativeLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" >

        <ImageView
            android:scaleType="centerCrop"
            android:id="@+id/actualimage"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignBottom="@+id/sampleimage"
            android:layout_alignLeft="@+id/sampleimage"
            android:layout_alignRight="@+id/sampleimage"
            android:layout_alignTop="@+id/sampleimage"
            android:src="@drawable/actualimage" />

        <ImageView
            android:visibility="invisible"
            android:id="@+id/sampleimage"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/sampleactualimage" />
    </RelativeLayout>
