Android——获取网络图片

布局

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    android:paddingBottom="@dimen/activity_vertical_margin"    tools:context="com.basillee.asus.demo.MainActivity3"><ImageView    android:id="@+id/imageView"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:layout_centerInParent="true"></ImageView></RelativeLayout>
