Issue on implementing action bar with tabs using support library

Question

I am implementing action bar with support library in my app. Min api level of my app is 8 and max is 19. In main activity class, I used android.app.ActionBar to import action bar, but it shows following error on getting action bar "Call requires API level 11 (current min is 8): android.app.Activity#getActionBar". So I changed import to 'android.support.v7.app.ActionBar' for action bar, now error changed to this ' cannot convert from android.app.ActionBar to android.support.v7.app.ActionBar'. My main activity code is as follow.

import android.app.FragmentTransaction;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.view.ViewPager;
import android.support.v7.app.ActionBar;
public class MainActivity extends FragmentActivity {
ViewPager Tab;
TabPagerAdapter TabAdapter;
ActionBar actionBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    TabAdapter = new TabPagerAdapter(getSupportFragmentManager());
    Tab = (ViewPager)findViewById(R.id.pager); 
    Tab.setOnPageChangeListener(
            new ViewPager.SimpleOnPageChangeListener() {
                @Override
                public void onPageSelected(int position) {
                  actionBar = getActionBar();
                  actionBar.setSelectedNavigationItem(position);                    }
            });
    Tab.setAdapter(TabAdapter);
    actionBar = getActionBar();
    //Enable Tabs on Action Bar
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
    ActionBar.TabListener tabListener = new ActionBar.TabListener(){
  @Override
  public void onTabReselected(android.app.ActionBar.Tab tab,
      FragmentTransaction ft) {
    // TODO Auto-generated method stub
  }
  @Override
   public void onTabSelected(ActionBar.Tab tab, FragmentTransaction ft) {
          Tab.setCurrentItem(tab.getPosition());
      }
  @Override
  public void onTabUnselected(android.app.ActionBar.Tab tab,
      FragmentTransaction ft) {
    // TODO Auto-generated method stub
  }};
  //Add New Tab
  actionBar.addTab(actionBar.newTab().setText("Android").setTabListener(tabListener));
  actionBar.addTab(actionBar.newTab().setText("iOS").setTabListener(tabListener));
  actionBar.addTab(actionBar.newTab().setText("Windows").setTabListener(tabListener));
}
}

android manifest is

 <?xml version="1.0" encoding="utf-8"?>
 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
 package="com.learn2crack.tab"
 android:versionCode="1"
 android:versionName="1.0" >

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

main_activity is

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.view.ViewPager
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent" />

windows_frag.xml is

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical" >
<TextView
    android:id="@+id/textView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="50sp"/>
</LinearLayout>

One of my fragment is

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
public class Windows extends Fragment {
@Override
  public View onCreateView(LayoutInflater inflater, ViewGroup container,
          Bundle savedInstanceState) {
    View windows = inflater.inflate(R.layout.windows_frag, container, false);
      ((TextView)windows.findViewById(R.id.textView)).setText("Windows");
      return windows;
 }}

Kindly help me out. I have also implemented following tutorial but error remain same.

Please don't suggest ActionBarSherlock. I want to know my issue before trying other library.

Answer 1

if you are using android.support.v7.app.ActionBar support package, you must use

actionBar = getSupportActionBar();

and change your activity like this

public class MainActivity extends ActionBarActivity
                          implements ActionBar.TabListener {
    // your code goes here
}
