   <ImageView
   android:id="@+id/imageView1"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:src="@drawable/ic_launcher" />

That is my imageView. When I try to change the image of it like this:

            Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.com_facebook_top_button);
            imageView1.setImageBitmap(bitmap);

the imageview seems to be invisible. The ic_launcher image disappears and the new image is not being shown.

have you do findViewById of imageView ? – Mitul Gedeeya Mar 20 '14 at 11:19
imageView1 = (ImageView) findViewById(R.id.imageView1); – Lara Mar 20 '14 at 11:22

I think there is some issue with your image `com_facebook_top_button`. Try `android:layout_width="fill_parent"` – AJ. Mar 20 '14 at 11:23

i didn't try but please try with doing imageView1.setimageDrawable(imageDrawable) or imageview.setimageresource(resource) – Mitul Gedeeya Mar 20 '14 at 11:24
Didn't work. Even changing the image doesn't work. – Lara Mar 20 '14 at 11:25

@Mitul The problem is I don't want to save my Bitmap object to a file. – Lara Mar 20 '14 at 11:29
convert bitmap to drawable and then set it using imageDrawable – Mitul Gedeeya Mar 20 '14 at 11:31
