ActionBar 오류

Question

SharLock 라이브러리를 사용하여 작업 표시 줄을 만들려고합니다. 내 프로젝트에 Sharlock 라이브러리가 추가되었습니다.

다음

내 코드는, 내 매니페스트 코드에서

public class MainActivity extends SherlockActivity implements ActionBar.OnNavigationListener { 

     @Override 
     protected void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.activity_main); 

      Button btnClick=(Button)findViewById(R.id.clickMe); 
      btnClick.setOnClickListener(new OnClickListener() { 

       @Override 
       public void onClick(View arg0) { 
        // TODO Auto-generated method stub 
        Intent intent=new Intent(MainActivity.this,ListNavigation.class); 
        startActivity(intent); 
       } 
      }); 
     } 

     @Override 
     public boolean onNavigationItemSelected(int itemPosition, long itemId) { 
      // TODO Auto-generated method stub 
      return false; 
     } 

,

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.example.actionbar" 
    android:versionCode="1" 
    android:versionName="1.0" > 

    <uses-sdk 
     android:minSdkVersion="8" 
     android:targetSdkVersion="16" /> 

    <application 
     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name" > 
     <activity 
      android:name=".MainActivity" 
      android:label="@string/app_name" android:theme="@style/Theme.Sherlock"> 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 

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

</manifest> 

내가 사용하고 있는데 일단은 SherlockActivity가 ActionBar.OnNavigationListener, 나는이 같은 오류를 얻고있다 ,

com.example.acctionbar.MainActivity 

acccccctionbar에는 두 개의 c가 있습니다. 코드에서이 철자를 검색하여 하나씩 변경하십시오. c.
