我是 android 和编码小游戏介绍屏幕的初学者。我的问题是，当我向介绍屏幕添加一些基本动画时，没有输出并且应用程序停止并出现这样的弹出窗口在此处输入图像描述，

当我评论动画方法时，它显示了简单的基于 xml 的布局，请帮助我这里的问题是我的 java 文件 

public class MainActivity extends Activity 
{
TextView  logo ;
TextView bottom  ;   
@Override
protected void onCreate(Bundle savedInstanceState)
{   
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    animate();
}
public void animate()
{  
    logo=  (TextView) findViewById(R.id.toplogo);
    bottom =(TextView) findViewById(R.id.footer);
    Animation fade1= AnimationUtils.loadAnimation(this, R.anim.fade_in);
    logo.setAnimation(fade1);

    Animation fade2=  AnimationUtils.loadAnimation(this, R.anim.fade_in2);
    bottom.setAnimation(fade2);

    fade2.setAnimationListener(new AnimationListener(){

        @Override
        public void onAnimationEnd(Animation animation)
        {
           startActivity(new  Intent(MainActivity.this, Menu.class));    
           MainActivity.this.finish();  
        }

        @Override
        public void onAnimationRepeat(Animation animation) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onAnimationStart(Animation animation) {
            // TODO Auto-generated method stub
    }}
    );

 }     
public void onpause()
{
    super.onPause();
    logo.clearAnimation();
    bottom.clearAnimation();        
}
public void onResume()
{
    super.onResume();
    animate();
}

}

问题是您没有在清单中声明活动

04-06 20:18:25.996: E/AndroidRuntime(812): android.content.ActivityNotFoundException: Unable to find explicit activity class {com.example.simplegame/android.view.Menu}; have you declared this activity in your AndroidManifest.xml?

更新

将此添加到您的清单中。并将包名称替换为您的包名称，例如 com.etc.xxx

    <activity
        android:name="*package name*.Menu"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MENU" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

您没有在AndroidManifest.xml.

记住谷歌是你的朋友，努力自学，从长远来看，它会让你受益。

在清单文件中，您忘记将布局引用到 java 文件。此外，当您想向应用程序添加新活动时，您需要为布局创建一个新的 xml 文件..和新的 java 类，这个类应该扩展 Activity，然后将 onCreate() 方法添加到此类。
