To turn it on/off programmatically, call ActionBar.show() and ActionBar.hide().
Example:
package com.exercise.AndroidActionBar;
import android.app.ActionBar;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class AndroidActionBarActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button showActionBar = (Button)findViewById(R.id.showactionbar);
Button hideActionBar = (Button)findViewById(R.id.hideactionbar);
showActionBar.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View arg0) {
ActionBar actionBar = getActionBar();
actionBar.show();
}});
hideActionBar.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View arg0) {
ActionBar actionBar = getActionBar();
actionBar.hide();
}});
}
}
