Code dùng reflection

// Hide the home title

ActionBar bar = getSupportActionBar();

bar.setDisplayShowTitleEnabled(false);

// bar.setDisplayShowHomeEnabled(false);

// pre-ICS

if (bar instanceof ActionBarImpl) {

       enableEmbeddedTabs(bar);

       // ICS and forward

} else if (bar instanceof ActionBarWrapper) {

       try {

              Field actionBarField = bar.getClass().getDeclaredField(

                           "mActionBar");

              actionBarField.setAccessible(true);

              enableEmbeddedTabs(actionBarField.get(bar));

       } catch (Exception e) {

              LogUtils.e(TAG, "Error enabling embedded tabs", e);

       }
