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>

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.)
You can change layout visibility just in the same way as for regular view. Use setVisibility(View.GONE) etc. All layouts are just Views, they have View as their parent.
Use this Layout in your xml file
<LinearLayout
android:id="@+id/contacts_type"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:visibility="gone">
</LinearLayout>
Define your layout in .class file
LinearLayout linearLayout = (LinearLayout) findViewById(R.id.contacts_type);
Now if you want to display this layout just write
linearLayout.setVisibility(View.VISIBLE);
and if you want to hide layout just write
linearLayout.setVisibility(View.INVISIBLE);
this is a programatical approach:
view.setVisibility(View.GONE); //For GONE
view.setVisibility(View.INVISIBLE); //For INVISIBLE
view.setVisibility(View.VISIBLE); //For VISIBLE
TextView view = (TextView) findViewById(R.id.textView);
view.setText("Add your text here");
view.setVisibility(View.VISIBLE);
