How to change visibility of layout programmatically

Question

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?

Answer 1

TextView view = (TextView) findViewById(R.id.textView);
view.setText("Add your text here");
view.setVisibility(View.VISIBLE);

Answer 2

this is a programatical approach:

 view.setVisibility(View.GONE); //For GONE
 view.setVisibility(View.INVISIBLE); //For INVISIBLE
 view.setVisibility(View.VISIBLE); //For VISIBLE

Answer 3

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:visibility

Parameters:
visibility     One 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.)

Answer 4

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.

Answer 5

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);
