Answer 1

this is how i achieve it

here is the code

@Override   
protected Dialog onCreateDialog(int id) {
    switch (id) {
    case DIALOG_LOADING:
        final Dialog dialog = new Dialog(this, android.R.style.Theme_Translucent);          
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setContentView(R.layout.loading);
        dialog.setCancelable(true);
        dialog.setOnCancelListener(new OnCancelListener() {             
            @Override
            public void onCancel(DialogInterface dialog) {
                //onBackPressed();
            }
        });
    return dialog;  

    default:
        return null;
    }
};

here is the loading.xml

call the dialog with

showDialog(DIALOG_LOADING);

hide it using

dismissDialog(DIALOG_LOADING);

UPDATE

if you want and custom indicator you can do the following in the layout.xml.

1. replace the ProgressBar with an ImageView
2. set the background of the ImageView to a AnimationDrawable
3. you can start the animation in onPrepareDialog
