Question

Currently I have a list view within it each row has a checkbox attached. I would like that once any checkbox is checked, at the bottom of the screen a view displays, and once none of the checkboxes are checked, the view automatically disappeared. Possible to do this?

Any help or direction is appreciated.
Thank you.

Yeah, you can do it.

Sounds like what you’re looking for is a floating view at the bottom…

Try this example:

<?xml version="1.0" encoding="UTF-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

  <LinearLayout android:orientation="vertical"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent">

    <ListView android:id="@android:id/list"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"/>
    <TextView android:id="@android:id/empty"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          android:text="@string/no_notes"/>

  </LinearLayout>

  <Button android:id="@+id/floating_button"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:text="Floating Button"
              android:padding="5dip"
              android:layout_margin="5dip"
              android:layout_gravity="right|bottom" />
</FrameLayout>

In this example I used a button at the bottom, but you an use any view.

And to hide it you can use android:visibility or setVisibility(int visibility)

Hope that helped…
