in my app i have placed three edit boxes with a ok button. Before pressing the ok button the user must enter all the edit text fields, if any of the edit text is been left empty i want to give an alert box.
in the edit text box the field name such as "Name", "Age" should be in diminished and when it is clicked it must get disappeared.
How to do this , pls anyone help me
Just use AlertDialog. Check all the conditions and if there is an error build a dialog and show it.
