Visibility of Gone takes still space of particular control in android?

问题

I am using the LinearLayout and inside there's button I am making visibilty gone based on supported states. SupportedStatuses are true then making Button as Visible but SupprtedStatuse are false then making button as Gone.

This is in a header and Button is Gone but still takes up the space. Here is the Layout which I am using.

<LinearLayout
            android:id="@+id/llparentView"
            android:layout_width="match_parent"
            android:layout_height="wrap_content
            android:orientation="vertical">
      <Button
            android:id="@+id/btn_change_status"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"/>
</LinearLayout>

Anybody have a good solution then it helps me a lot.

回答1:

You could use a FrameLayout around whatever layout you are using For example:

<FrameLayout android:layout_width="match_parent" android:layout_height="wrap_content">

    <!-- put your views here -->
</FrameLayout>

This will ensure when using View.GONE the FrameLayout collapses on the space.

Try to wrap your button in another Linear/Frame layout and change their visibility as well.
