Add a button in bottom of listview when the listview is empty (using ListActivity)

Question

I using extends ListActivity to show the empty message when the list are empty. Below is my xml file:

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

    <ListView android:id="@+id/android:list"
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:layout_weight="1.0">
    </ListView>

    <TextView android:id="@android:id/empty"
               android:layout_width="match_parent"
               android:layout_height="match_parent"
               android:text="No Items! Please Add!"/> 

    <Button
        android:id="@+id/button1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"        
        android:text="Add Item" />

</LinearLayout>

My problem is the button can only appear when there have item in list, but can't appear when the list is empty. How can the button appear when the list are empty?

You can dynamically check if there exist element to show in the list and if not, then set the visibility as GONE. — Sandeep, May 22 '13 at 08:41

At first check getCount(). If getCount() return 0, then the visibility of button should be visible otherwise 'invisible' or 'gone'

Just use the the android tag android:visible buttons codes in xml reference id you can set

button.setVisibility(View.Visible or View.inVisible) based on your requirement.

You should create a footer view layout inside your listview's layout.

View footer = ((LayoutInflater) ActivityContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.footer, null, false);

ListView.addFooterView(footer);

Also check this link.

You can check if the ListView doesn't have items in it by doing

listview.getAdapter().isEmpty

If it is, set the button's visibility to gone. Otherwise, visible
