Android ActionBar backbutton and tabs

问题

I want to create an ActionBar and a tabbed navigation like the google+ app.

I used this example as a starting point and now I have a great actionbar:

http://developer.android.com/resources/samples/ActionBarCompat/index.html

I've also included a ViewPager and a TabHost to have tabs and scrolling left/right Fragments.

What i need is to show the back arrow in version prior to honeycomb. If I set getActionBar().setDisplayHomeAsUpEnabled(true), the arrow is automatically show in version >= honeycomb.

How can I do that in version prior to honey?

What I also want to have is Tabs like the google+ app.

This is how is my tab bar looks:

removed dead ImageShack link

...and this is what i want:

removed dead ImageShack link

I can't find any example to style tab bars like that one.

回答1:

I would recommend you the ActionBarSherlock for ActionBar compatibility with Android <3. It is a better implementation that the example offered in the developers page.

Using this package, the back arrow will appear when you add to your activity the following line.

getSupportActionBar().setDisplayHomeAsUpEnabled(true);

Regarding the Google+ tabs, I have found the widget ViewFlow very useful and looking exactly the same. Moreover, you don't have any backward compatibility issues. Have a look to the CircleFlowIndicator example.

You can use ActionBarSherlock and a ViewPager with ViewPagerIndicator to achieve the desired look. These libraries also work pre ICS.

As miguel.rodelas suggested, use getSupportActionBar().setDisplayHomeAsUpEnabled(true) for the home arrow. In onOptionsItemSelected you can catch it by the id android.R.id.home.

ActionBar actionBar = getActionBar();
        actionBar.setDisplayShowHomeEnabled(false);
        actionBar.setDisplayShowTitleEnabled(false);

//use your custom xml view here

View actionBarView = getLayoutInflater().inflate(R.layout.action_bar_custom_view, null);
        actionBar.setCustomView(actionBarView);
        actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);

//your logic for click listner

setListenerForActionBarCustomView(actionBarView);

As stated, download the ActionBarSherlock and import it as a library here https://api.github.com/repos/JakeWharton/ActionBarSherlock/zipball/4.2.0

Instead of using getActionBar use getSupportActionBar
Download the support library
Instead of Activity, extend your class as SherlockActivity
Same with fragments, use SherlockFragment

Then just copy your code, should work perfectly.
