getSupportActionBar().setDisplayShowCustomEnabled(true); // is for specify use custom bar 
getSupportActionBar().setCustomView(R.layout.iguepardos_action_bar);  // my custom layout
getSupportActionBar().setDisplayHomeAsUpEnabled(true); // Button for come back

View mCustomView = getSupportActionBar().getCustomView(); // Set the view
TextView TitleToolBar = (TextView) mCustomView.findViewById(R.id.toolbar_title); // find title control
TitleToolBar.setText("The Title Show"); // Set the Title
