여기까지 하면 왼쪽 Package Explorer에 RotationTestApp이라는 프로젝트가 생기고 activity_main.xml이 열린다. 화면에는 앱 이름 Rotation Test App과 함께 Hello world! 도 찍혀 있다...

2 MainActivity.java 수정

package com.example.rotationtestapp;

import android.os.Bundle;
import android.app.Activity;
import android.content.res.Configuration;
import android.graphics.Point;
import android.widget.RelativeLayout;

public class MainActivity extends Activity {
	private RelativeLayout layout1; 
	private RelativeLayout layout2; 

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);

		layout1 = (RelativeLayout) findViewById(R.id.relativeLayout1);
		layout2 = (RelativeLayout) findViewById(R.id.relativeLayout2);
		AdjustLayout();
	}

	@Override
	public void onConfigurationChanged(Configuration newConfig) {
		super.onConfigurationChanged(newConfig);
		AdjustLayout();
	}

	private void AdjustLayout() {
		Point point = new Point();
		getWindowManager().getDefaultDisplay().getSize(point);
		boolean is_landscape = point.x > point.y;

		RelativeLayout.LayoutParams layparam1 = (RelativeLayout.LayoutParams) layout1.getLayoutParams();
