Validation for not storing the null values in database from activity
<p>My activity has 3 edittext and a button. </p>

<p>I am <strong>storing the values in the database</strong>. When I am not inserting any value in the the edittext it should not enter the null values instead it should give some alert for that but in my program it accepts the null value also. </p>

<p><strong>How to handle this validation?</strong></p>
