1. ImageView.java 생성
2. View 클래스를 상속받은 클래스는 생성자가 반드시 있어야 하므로 ImageView(Context context) {...} 생성
3. 콘텍스트에서 리소스를 가져온다.
4. 가져온 리소스를 디코드한다.
5. onDraw()를 오버라이드하여 drawBitmap()으로 그림을 그린다.
ImageTest.java

package net.itisn.test;
import android.app.Activity;
import android.os.Bundle;
public class ImageTest extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.main);
setContentView(new ImageView(this));
