I apologize if I did it wrong.</p> <p>I am learning Android Development and just experimenting and creating my first app and somehow I encountered a problem where one of my buttons do not work, even when I have added the button listeners correctly.</p> <p>When I type "kev" as the password on the main layout and press the button, it will take me to NextActivity Layout via the "setContentView(.....)" this works fine.</p> <p>The problem is, when I am in the NextActivity Screen, it will have a button. Somehow when I click on that button, it does nothing. I am sure the code is right. Can someone help me out here?</p> <p>Thanks</p>

    1. COYou should use intent, not setContentView. You are only setting the xml layout resource, not your next activity.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
