Question

Recently i have successfully implemented the ActionBarSherlock Demos sample in eclipse. But there is something that i am not able to understand it that how this library automatically creates the header with one icon and a text “ActionBarSharelock Demos” in tab_navigation.xml by using merely a LinearLayout

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:padding="20dip">
</LinearLayout>

This library is new for me and i am so anxious to know, how this library creates it?

I created a new android project on target api 15 and attach the ActionBarSherlock library to it. then i found that there some of the files are missing from my new android project when i compared it to demos sample project of android. Those files are listed below.

1.pom.xml
2.bin/classes.dex
3.bin/jarlist.cache
4.bin/resources.ap_

Moreover i got a new error in my activity file on eclipse “R cannot be resolved to a variable.”

If you know anything about my problem then please share your views.

To use the simplest example:

public class Simple extends SherlockActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        setTheme(SampleList.THEME); //Used for theme switching in samples
        super.onCreate(savedInstanceState);
        setContentView(R.layout.text);
        ((TextView)findViewById(R.id.text)).setText(R.string.simple_content);
    }
}

All you have to do is let your activity inherit one of the Sherlock activites (e.g., SherlockActivity, SherlockFragmentActivity).

You can program the action bar by using the getSupportActionBar() method of the SherlockActivity, e.g. to set the title: getSupportActionBar().setTitle( R.string.my_title );
