java - 添加动画时 Android 应用程序停止

Question

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，应用程序停止并弹出这样的窗口 ,

当我评论动画方法时，它显示了简单的基于 xml 的布局，请帮助我我的 java 文件哪里有问题

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();
}

动画文件

   fade_in2.xml
   <?xml version="1.0" encoding="utf-8"?>
  <set  xmlns:android="http://schemas.android.com/apk/res/android"
 android:shareInterpolator="false">
  <alpha
    android:fromAlpha="0.0"
    android:toAlpha="1.0"
    android:duration="2500"
    android:startOffset="2500">
 </alpha>

 </set >

以同样的方式 fade_in.xml 等。请帮我解决问题，逻辑/代码有什么问题，它不能与 animation 一起工作..

编辑错误日志..

我不确定我是否复制了需要的一个，请看这个(我确实在 logcat 选项卡的下拉列表中选择了错误)

Answer 1

问题是你没有在 list 中声明 Activity

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?

已更新

将此添加到您的 list 中。并将 package name 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>
