Answer 1

public void forceTabs() {
            try {
                Method setHasEmbeddedTabsMethod = actionBar.getClass()
                    .getDeclaredMethod("setHasEmbeddedTabs", boolean.class);
                setHasEmbeddedTabsMethod.setAccessible(true);
                setHasEmbeddedTabsMethod.invoke(actionBar, true);
            }
            catch(final Exception e) {
                // Handle issues as needed: log, warn user, fallback etc
                // This error is safe to ignore, standard tabs will appear.
            }
      }

在oncreate方法中调用此方法。
