1.主要思路：在Android Studio 中 新建游戏界面，并构造出主线程，另外在创建一个类作为游戏界面，在界面在新建一个方法，目的是交由游戏界面类调用；
2.具体方法（代码）：
package com.example.fpl.helloworld;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
/**

public class GameSurface extends SurfaceView implements SurfaceHolder.Callback {
private GameMenu gameMenu;
private Bitmap bmpMainBG;
private Bitmap bmpLogo;
private Bitmap bmpButton;
private Bitmap bmpText;
public static int screenwidth;
public static int screenheight;
private SurfaceHolder surfaceHolder;
private Canvas canvas;

public GameSurface(Context context) {
super(context);
surfaceHolder = this.getHolder();
surfaceHolder.addCallback(this);
paint=new Paint();
paint.setAntiAlias(true);
}
@Override

screenwidth=this.getWidth();
screenheight=this.getHeight();
initBitmap();
new Thread(new Runnable() {
@Override

}).start();
}

canvas=surfaceHolder.lockCanvas();
gameMenu.draw(canvas,paint);
if (canvas!=null){
surfaceHolder.unlockCanvasAndPost(canvas);
}
}

bmpMainBG= BitmapFactory.decodeResource(this.getResources(),R.drawable.mainmenu);

}
@Override
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
}
@Override

}
}
