There is the way to change visibility of View, but how can I change programmatically visibility of layout defined in XML? How to get layout object?
<LinearLayout android:id="@+id/contacts_type" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content" android:visibility="gone"> </LinearLayout>

You can also set the visibility in your layout. xml if you want it hidden when your application first starts. android:visibility="gone" should do the trick. This way it is hidden from the very start when the layout is initialized by your app.
Go to -> Edit File Templates option. Change the ${ROOT_TAG} to LinearLayout in both of these LayoutResourceFile. xml and LayoutResourceFile_vertical. xml and you will always get LinearLayout as parent for future.
Have a look at View.setVisibility(View.GONE / View.VISIBLE / View.INVISIBLE).
From the API docs:
public void setVisibility(int visibility)Since: API Level 1
Set the enabled state of this view.
Related XML Attributes: android:visibilityParameters:
visibilityOne of VISIBLE, INVISIBLE, or GONE.
Note that LinearLayout is a ViewGroup which in turn is a View. That is, you may very well call, for instance, myLinearLayout.setVisibility(View.VISIBLE).
This makes sense. If you have any experience with AWT/Swing, you'll recognize it from the relation between Container and Component. (A Container is a Component.)
