- 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

@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);

能否回答的详细一点，学的时间短，求帮忙
解决方案
放到你结束按钮的点击事件里：
Intent intent=new Intent(thisBaomingActivity.class);startActivity(intent);解决方案二：
把
Intent intent=new Intent(thisBaomingActivity.class);
startActivity(intent);
放到开始里。
