Android 怎么将主程序添加到欢迎界面里面

我做好了一个欢迎界面,并且做了下按钮触发,里面什么都还没有,我这边有一个游戏主程序,应该怎么样才能合理的添加进去呢? 添加的结果就是 点击这个按钮 就进入这个主程序。下面是代码
这个是我的欢迎界面的代码
package sen.tan;

import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.util.DisplayMetrics;
import android.view.KeyEvent;
import android.view.MotionEvent;
import android.view.View;
import android.view.Window;
import android.view.WindowManager;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;

public class dazhuankuaiActivity extends Activity {
BallView myview;
public static int screenWidth ;
public static int screenHeight;
private TextView textview;
Button kaishi,jieshu,guanyu;
ImageView image;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String string = "欢迎进入疯狂打砖块游戏";
image = (ImageView) this.findViewById(R.id.image);
image.setImageResource(R.drawable.img1);
textview =(TextView) this.findViewById(R.id.textview);
textview.setTextSize(20);
textview.setTextColor(Color.GREEN);
textview.setBackgroundColor(Color.RED);
textview.setText(string);
kaishi=(Button)findViewById(R.id.button1);
guanyu=(Button)findViewById(R.id.button2);
jieshu=(Button)findViewById(R.id.button3);
kaishi.setWidth(250);
guanyu.setWidth(200);
jieshu.setWidth(150);
kaishi.setTextSize(35);
guanyu.setTextSize(29);
jieshu.setTextSize(24);

    jieshu.setOnClickListener(new Button.OnClickListener(){
        public void onClick(View v)
        {
            dazhuankuaiActivity.this.finish();
        }


    });
    guanyu.setOnClickListener(new Button.OnClickListener(){
        public void onClick(View v){
            textview.setText("本游戏由xxx制作,此游戏控制左右按键,来回移动挡板,不让小球掉落,当小球把上方砖块全部打完时,游戏胜利");
        }
    });
    kaishi.setOnClickListener(new Button.OnClickListener(){
         public void onClick(View v)
         {
         }
    });
