Android HttpClient, GET, image

안드로이드에서 HttpClient를 이용하여 웹사이트의 이미지를 가져와서 출력하는 예

res/layout/main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/linearLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" />

</LinearLayout>

AndroidManifest.xml 에는 다음과 같이 권한을 설정하는 부분이 있어야 한다

<uses-permission android:name="android.permission.INTERNET"/>
