What am I doing wrong?

Ben Jakuben

I don't know what I'm doing wrong here...

import android.app.ActionBar;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;

public class MainActivity extends FragmentActivity implements
        ActionBar.TabListener {

    // Some code has been omitted for brevity!

    public ActionBar mActionBar;

    public void onCreate(Bundle savedInstanceState) {

        mActionBar = getActionBar();

        PagerAdapter pagerAdapter = new PagerAdapter(getSupportFragmentManager());

        // Some code omitted for brevity...

        for (int i = 0; i < pagerAdapter.getCount(); i++) {
            ActionBar.Tab tab = mActionBar.newTab();

             * Add your code here to set the text!


    // These listener methods are intentionally blank
    public void onTabSelected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) { }

    public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) { }

    public void onTabReselected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) { }

Click on the "Preview" button to see the syntax error you get with this code. It's an understandable mistake: use pagerAdapter instead of PagerAdapter.
