my listview is a fragment and this image is default, so i have to create another fragment if arraList.size()<1, but i dont want to create another fragment. My question is how to replace this image to another image or a text view without creating another fragment?ridvanzoro– ridvanzoro2013-12-02 13:14:16 +00:00Commented Dec 2, 2013 at 13:14

The common way is setting an empty textview (@android:id/empty) after the listview:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView
android:id="@android:id/list"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:dividerHeight="1dp" >
</ListView>
<TextView
android:id="@android:id/empty"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/empty_list" />
</LinearLayout>
And then set set the empty view to the listview:
ListView lv = (ListView)findViewById(android.R.id.list);
TextView emptyText = (TextView)findViewById(android.R.id.empty);
lv.setEmptyView(emptyText);
This should show items in the list whenever they are, and show the textview when not.

With a Toast.
if(list == null || list.size() == 0)
Toast.makeText(context, "The list is empty", Toast.LENGTH_SHORT).show();

A Toast is not ideal.you want the user to always see a message telling them there is nothing to display at the moment.
