Today I came across this setEmptyView() method of ListView. Many times it happens that we make a call on web service and we receive nothing in response at that time listview is displayed blank. At that time we should display messages like:
- No Records Found.
- No Data Found.
- No Items Found.
How do we handle such situation when there is nothing(empty) to display inside the Android – ListView?
By using setEmptyView() of ListView, we can set the view and can appear in the screen whenever the adapter is empty.
For example,
ListViewLayout.xml
01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | < LinearLayout android:id = "@+id/LinearLayout1" android:layout_width = "match_parent" android:layout_height = "match_parent" android:layout_below = "@+id/layoutTitlebar" > < ListView android:id = "@+id/listViewFriends" android:layout_height = "match_parent" android:layout_width = "match_parent" android:background = "@color/friendBGColor" android:cacheColorHint = "#00000000" > </ ListView > < TextView android:id = "@+id/empty" android:text = "@string/strNoRecordsFound" android:layout_width = "fill_parent" android:layout_height = "fill_parent" style = "@android:style/TextAppearance.Large" android:gravity = "center" > </ TextView > </ LinearLayout > |
And Now, write this code to define Empty view:
1 2 3 4 5 | ListView listViewFriends = (ListView) findViewById(R.id.listViewFriends); // set your adapter here // set your click listener here // or whatever else listViewFriends.setEmptyView(findViewById(R.id.empty)); |
