Force stacked tabs

Question

Is there any way to force stacked tabs? I want tabs separate of action bar (in a second row), even when landscape mode.

I am trying to force it but I can´t. For example, Twitter app in Android, when change to lanscape mode, continue showing two rows (tabs in a separate rows, which are known as stacked tabs).

Thanks!

Answer 1

Not only can you not force stacked tabs, you can't even force tabs -- Android can and will replace them with a drop-down list for navigation in some screen sizes and orientations.

Your only solution is to move away from action bar tabs, such as by using ViewPager and PagerTabStrip.

I had luck using the following reflection 'hack':

private void forceStackedTabs() {
    ActionBar ab = getSupportActionBar();
    if ( ab instanceof ActionBarImpl ) {
        // Pre-ICS
        disableEmbeddedTabs( ab );
    } else if ( ab instanceof ActionBarWrapper ) {
        // ICS
        try {
            Field abField = ab.getClass().getDeclaredField( "mActionBar" );
            abField.setAccessible( true );
            disableEmbeddedTabs( abField.get( ab ) );
        } catch (NoSuchFieldException e) {
            Log.e( TAG, "Error disabling actionbar embedded", e );
        } catch (IllegalArgumentException e) {
            Log.e( TAG, "Error disabling actionbar embedded", e );
        } catch (IllegalAccessException e) {
            Log.e( TAG, "Error disabling actionbar embedded", e );
        }
    }
}
private void disableEmbeddedTabs(Object ab) {
    try {
        Method setHasEmbeddedTabsMethod = ab.getClass().getDeclaredMethod("setHasEmbeddedTabs", boolean.class);
        setHasEmbeddedTabsMethod.setAccessible(true);
        setHasEmbeddedTabsMethod.invoke(ab, false);
    } catch (Exception e) {
        Log.e( TAG, "Error disabling actionbar embedded", e );
    }
}

Please note that I didn't think of this myself, but simply rewrote the code given in this answer: replicate ActionBar Tab(s) with custom view
