ViewPager and Actionbar Items to control multiple WebView's

Issue

Im having troubles adding Actionbar Items to control my Viewpager screens, I want to be able to control the viewpager depending on which page is pulled up. I really just have 3 webviews i want to add actionbar items to control the webview via the Actionbar (Refresh, Back, Forward). Thank you in advance for any help you provide. Thanks

Code

public class AwesomePagerActivity extends SherlockActivity {

private ViewPager awesomePager;
private static int NUM_AWESOME_VIEWS = 3;
private Context context;
private AwesomePagerAdapter awesomeAdapter;
LayoutInflater inflater ;



/** Called when the activity is first created. */

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    // Set up the action bar.
    getSupportActionBar().show();

    context = this;

    inflater = (LayoutInflater)
            context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    awesomeAdapter = new AwesomePagerAdapter();
    awesomePager = (ViewPager) findViewById(R.id.pager);
    awesomePager.setOffscreenPageLimit(3);
    awesomePager.setAdapter(awesomeAdapter);

    //Title Page
    //Get a reference to the TitlePageIndicator
    TitlePageIndicator awesomeIndicator = (TitlePageIndicator) findViewById(R.id.indicator);
    // Attach adapter to ViewPager
    awesomePager.setAdapter(awesomeAdapter);

    // Attach ViewPager to the indicator
    awesomeIndicator.setViewPager(awesomePager);

}

public boolean onCreateOptionsMenu(com.actionbarsherlock.view.Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    //super.onCreateOptionsMenu(menu);
    //getMenuInflater().inflate(R.menu.activity_enlighten_webview_secondary, menu);
    MenuInflater Inflater=getSupportMenuInflater();
    Inflater.inflate(R.menu.menu, menu);

Solution

I've rewritten your initial code into something that should do what you want:

public class AwesomePagerActivity extends Activity {

private ViewPager awesomePager;
private static int NUM_AWESOME_VIEWS = 3;
private Context context;
private AwesomePagerAdapter awesomeAdapter;
LayoutInflater inflater;

/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    context = this;
    inflater = (LayoutInflater)
    context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    awesomeAdapter = new AwesomePagerAdapter();
    awesomePager = (ViewPager) findViewById(R.id.pager);
    awesomePager.setOffscreenPageLimit(3);
    awesomePager.setAdapter(awesomeAdapter);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {     
    MenuInflater Inflater = getSupportMenuInflater();
    Inflater.inflate(R.menu.menu, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem Item) {
    final int current = awesomePager.getCurrentItem();
    int currentId = current == 0 ? R.id.webView1
            : (current == 1 ? R.id.webView2 : R.id.webView3);
    WebView web = (WebView) findViewById(currentId);
    switch (Item.getItemId()) {
    case R.id.menu_back:
        web.goBack();
        return true;
    case R.id.menu_forward:
        web.goForward();
        return true;
    case R.id.menu_refresh:
        web.reload();
        return true;
    }
    return super.onOptionsItemSelected(Item);
}

private class AwesomePagerAdapter extends PagerAdapter {

    public int getCount() {
        return NUM_AWESOME_VIEWS;
    }

    public Object instantiateItem(View collection, int position) {
        View layout = null;
        LayoutInflater mInflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        WebView web = null;
        switch (position) {
        case 0:
            layout = mInflater.inflate(R.layout.activity_main, null);
            web = (WebView) layout.findViewById(R.id.webView1);
            web.loadUrl("http://developer.android.com");
            break;
        case 1:
            layout = mInflater.inflate(R.layout.activity_community, null);
            web = (WebView) layout.findViewById(R.id.webView2);
            web.loadUrl("http://www.xda-developers.com");
            break;
        case 2:
            layout = mInflater.inflate(R.layout.activity_support, null);
            web = (WebView) layout.findViewById(R.id.webView3);
            web.loadUrl("http://www.samsung.com");
            break;
        }
        WebSettings websettings = web.getSettings();
        websettings.setBuiltInZoomControls(position == 0 ? false : true);
        websettings.setUseWideViewPort(position == 0 ? true : false);
        websettings.setJavaScriptEnabled(true);
        websettings.setAllowFileAccess(true);
        websettings.setDomStorageEnabled(true);
        websettings.setLoadWithOverviewMode(true);
        web.requestFocusFromTouch();
        web.setWebViewClient(new WebViewClient());
        web.setWebChromeClient(new WebChromeClient());
        websettings.setSavePassword(true);
        ((ViewPager) collection).addView((View) layout);
        return layout;
    }

    public void destroyItem(View collection, int position, Object view) {
        ((ViewPager) collection).removeView((View) view);
    }

    public boolean isViewFromObject(View view, Object object) {
        return view == ((View) object);
    }

}
}
