Show Hide Sherlock Action Bar

I have added Sherlock action bar to an activity by using the following line in manifest:

android:theme="@style/Theme.Sherlock.Light"

I want to save on screen space and hide the action bar by default and show it only when user taps on the screen. I have seen it in Aldiko app but don't know how to implement it.

Any help is welcomed.

for interest you might want to look into the Full Screen app template that you can get when you choose to start a New Application in Eclipse. There is some nice code for auto-hiding the action bar. - Richard Le Mesurier

To hide use below code on your activity onCreate() method,

getSupportActionBar().hide();

To show use below code on tap event,

getSupportActionBar().show();

Follow ActionBarSherlock Usage for more details.

First give the id to your wrapping node of activity layout (main_layout.xml):

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
    android:id="@+id/containerMain"

Second implement this in your code for activity:

boolean isActionBarShow=true;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main_layout);

    a=getSupportActionBar();
    RelativeLayout rl= (RelativeLayout)findViewById(R.id.containerMain);
    rl.setOnTouchListener(new OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (event.getAction()==MotionEvent.ACTION_DOWN)
                if (isActionBarShow)
                {
                    a.hide();
                    isActionBarShow=false;                      
                }
                else
                {
                    a.show();
                    isActionBarShow=true;

                }
            return false;
        }
    });
