Get Actionbar App Compat to show actionbar buttons in pre Honeycomb devices

If you want to show button in the ActionBar while using AppCompat V7 in Gingerbread or Froyo you need to add the following code in your onCreate function.

ActionBarPolicy.get(this).showsOverflowMenuButton();

By default Overflow menu buttons are disabled in pre honeycomb devices like Gingerbread and Froyo. The above API call enables it.

Tutorial ActionBarCompat

Using ActionBarCompat is almost as easy as native bar, and even similar to ActionBarSherlock, but there are a few differences that must be know. This tutorial covered the most simple integration. It is pretty simple to use and implement ActionBarCompat, but we have to pay attention when we add it to our project. In Android Studio it is very very simple. Open build.gradle and add this:

dependencies compile 'com.android.support:appcompat-v7:18.0.+'

In ADT (Eclipse) you can add it as a library project based on code that you can find in sdk\extras\android\support\v7\appcompat. It is described here. Pay attention. In your project you have to add this library project.

So let’s create a new project using API 18 and add the project under sdk\extras\android\support\v7\appcompat folder. I will set light theme with dark Action Bar. It is easy:

Now your activity needs to extend ActionBarActivity instead. This activity is based on FragmentActivity, so you will be able to use fragments without any extra effort. It’s easy:

public class MainActivity extends ActionBarActivity /** * Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) super.onCreate(savedInstanceState); setContentView(R.layout.main);

And here it is! But what if we want to add some menu items? It’s pretty much the same, but some attributes require our custom namespace:

Now you can inflate the menu:

@Override public boolean onCreateOptionsMenu(Menu menu) getMenuInflater().inflate(R.menu.main, menu); return true;

f you need to access Action Bar programatically, you will call getSupportActionBar()

Adding an Action View Action Views are those helpful views that can be added over the Action Bar when the user presses a menu item. The most typical is the Search View, and that’s the one I’m explaining here. Every Action View has been added to the support library, so you will need to add the reference to it instead of the one in the SDK:

Recovering this Action View from code is a little bit different. MenuItemCompat will do the hard work this time:

private SearchView mSearchView; @Override public boolean onCreateOptionsMenu(Menu menu) getMenuInflater().inflate(R.menu.main, menu); MenuItem searchItem = menu.findItem(R.id.action_search); mSearchView = (SearchView) MenuItemCompat.getActionView(searchItem); return true;

Now it’s time to show the search view when the user presses the magnifying glass icon. No difference with native Action Bar:

@Override public boolean onOptionsItemSelected(MenuItem item) switch(item.getItemId()) ... case R.id.action_search: mSearchView.setIconified(false); return true; ... return false;

You can add an OnQueryTextListener to detect user input on SearchView

public class MainActivity extends ActionBarActivity implements SearchView.OnQueryTextListener ... @Override public boolean onCreateOptionsMenu(Menu menu) ... mSearchView = (SearchView) MenuItemCompat.getActionView(searchItem); mSearchView.setOnQueryTextListener(this); return true; ... @Override public boolean onQueryTextSubmit(String s) Toast.makeText(this, s, Toast.LENGTH_LONG).show(); return true; @Override public boolean onQueryTextChange(String s) return false;

Conclusion Apart from using some new classes and very little coding changes, the process of adding a new action view is similar and straightforward. If you have done this before, it will be easy.

In July 2013 Google announced ActionBarCompat as part of its support library package. This library makes it easy to use the Action Bar that have to support older devices. Many have waited for this to happen ever since the Action Bar was introduced with Honeycomb...

Adding ActionBarCompat support - Intellij IDEA

Adding the new ActionBarCompat support may be a little tricky.

First, you have to download the new Support library from the SDK manager. When it's there, you have to go to your project settings (click your module, then press F4). Select "Modules" and add a new module by importing it. Select "C:\android\sdk\extras\android\support\v7\appcompat" (provided your android sdk is installed in C:\android\sdk), and "Create module from existing sources". Press "next" a few times, and "Finish" in the last step.

Now, go to your modules again and select your app's main module. Go to the "Dependencies" tab, and press the "Add" button on the right side of the window. Select "Module dependency", then the module added using the instructions above. The next step is importing the library. Click the "Add" button again, only now choose the "Library" option. Click "New library" and navigate to "C:\android\sdk\extras\android\support\v7\appcompat\libs" (again, the path depends on the android sdk location), select "android-support-v7-appcompat.jar". In the "Configure library" window, press OK.
