How to add progressbar to ActionBarSherlock

Question

Is it possible to add progressbar to ActionBarSherlock? I need to show and hide it in particular time. But it has to be located inside ActionBarSherlock. Code of my class. you can see, that I use requestWindowFeature(Window.FEATURE_PROGRESS) but it doesn`t make any difference. The same result. : ``` public class RecipeActivity extends SherlockActivity { private String picture; private String TAG = "RecipeActivity"; private ImageView viewPicture; private RecipeGeneral recipeGeneral; private Recipe recipe; private String [] pictures; private ArrayList<Step> steps; //private ImageView viewStar; private DataBaseFactory db; private NyamApplication application; private TextView viewDescription; private TextView userView; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_PROGRESS); setProgressBarIndeterminateVisibility(true); try { setContentView(R.layout.recipe_page); getSupportActionBar().setDisplayShowTitleE…

Accepted Answer

Yes, you can, ABS has such feature. Next piece of code is from Demos sample app of ABS:

```
public class Progress extends SherlockActivity  {
    Handler mHandler = new Handler();
    Runnable mProgressRunner = new Runnable() {
        @Override
        public void run() {
            mProgress += 2;

//Normalize our progress along the progress bar's scale
            int progress = (Window.PROGRESS_END - Window.PROGRESS_START) / 100 * mProgress;
            setSupportProgress(progress);

if (mProgress < 100) {
                mHandler.postDelayed(mProgressRunner, 50);
            }
        }
    };

private int mProgress = 100;

@Override
    protected void onCreate(Bundle savedInstanceState) {
        setTheme(SampleList.THEME); //Used for theme switching in samples
        super.onCreate(savedInstanceState);

//This has to be called before setContentView and you must use the
        //class in com.actionbarsherlock.view and NOT android.view
        requestWindowFeature(Window.FEATURE_PROGRESS);

setContentView(R.layout.progress);

findViewById(R.id.go).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View arg0) {
                if (mProgress == 100) {
                    mProgress = 0;
                    mProgressRunner.run();
                }
            }
        });
    }
}
```

this sample you can find in samples\demos\ directory of ABS (Progress.java in eclipse workspace)
