解决方案：

 <activity
        android:name=".Specials"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="com.kita.MyGardenCenterApp.SPECIALS" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

确定臭名昭著的“未找到活动”错误。

按钮：

Button btnSpecials = (Button) findViewById(R.id.btnSpecials);
    btnSpecials.setOnClickListener(new View.OnClickListener() {  

        public void onClick(View v) {
            // TODO Auto-generated method stub
            startActivity(new Intent("com.kita.MyGardenCenterApp.SPECIALS")); 
        }
    });

显现：

<activity
        android:label="@string/app_name"
        android:name=".Specials" >
        <intent-filter >
            <action android:name="android.intent.action.SPECIALS" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

为了回应您的一些答案，我有另一个使用以下代码的应用程序，它工作正常。这就是为什么我在这里问。我想以正确的方式做到这一点。

我的 .java 文件也是 Specials.java

<activity
        android:label="@string/app_name"
        android:name=".mainAboutUs" >
        <intent-filter >
            <action android:name="com.kita.PapaStew.MAINABOUTUS" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

我认为您尚未将新创建的活动添加到清单文件中

只需将其添加为

<activity
        android:name="com.kita.MyGardenCenterApp.SPECIALS"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

用这个 

      <intent-filter>
            <action android:name="com.kita.MyGardenCenterApp.SPECIALS" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>

<activity
    android:label="@string/app_name"
    android:name=".Specials" >

应该

<activity
    android:label="@string/app_name"
    android:name=".SPECIALS" >

反之亦然，您通过大写类名来打破命名约定。

此外，您的意图过滤器已关闭。

正如其他答案所述，您需要将意图过滤器中的操作更改为：

<action android:name="com.kita.MyGardenCenterApp.SPECIALS" />
