I am trying to create action bar using SharLock Library, I am added Sharlock library in my project.

Here is my code,

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;
        }

In my manifest code,

<?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>

Once i'm using extends SherlockActivity implements ActionBar.OnNavigationListener, I am getting error like this,

logcatは、アクティビティを開始したことを示しています。

com.example.acctionbar.MainActivity

acccccctionbarには2つのcがあります。コードでこのスペルを検索し、1つ変更します。
