how to change image in android while switching between activities

in my app in activity A i have a list view showing some details along with an image at the bottom and a button at the top. When the user clicks in the list it opens a new activity B.

If the user clicks the back button he returns back to activity A and there i want to show a new Image in the image View. At the same time there should not be any change in the activity A.

In iPhone we are to use a method called View will appear.

like that is there any method in android. How to do this, please help me friends.....

Instead of using startActivity to start an activity use startActivityForResult. If you are in Activity A onitemclick event use the following code to start activity B

Intent intent = new Intent(WebViewTest.this,
B.class);
startActivityForResult(intent, 500);

write the image updation code inside following method so that when activity B is finished the control comes to the following method. You can use Handler concept also to update image

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);
        System.out.println(requestCode + "...called from another activity..."
                + resultCode);
        if (requestCode == 500) {

                //upate image

        }

    }

Thanks Deepak
