代码实现屏幕切换

package com.example.android029;


import android.app.Activity;
import android.content.pm.ActivityInfo;
import android.os.Bundle;


public class MainActivity5 extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
//设置屏幕横屏
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
//设置屏幕竖屏
//setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}
//在屏幕横竖屏切换时，调用该方法保存Activity的状态
@Override
protected void onSaveInstanceState(Bundle outState) {
// TODO Auto-generated method stub
super.onSaveInstanceState(outState);
}


}
