Android AlertDialog Programatically Example

In Android Programming we have AlertDialogs the way we have HTML. We can have OK and CANCEL buttons with and Title and text messages/info.

1. Create an object of AlertDialog.Builder from android.app.AlertDialog package.

AlertDialog.Builder alertDialog = new AlertDialog.Builder(this);

2. Set the Title for the Alert Dialog using setTitle() method.

alertDialog.setTitle("Android Alert Message");

3. Set the Message for the Alert Dialog using setTitle() method.

alertDialog.setMessage("Put your description text here!");

4. Now if you want to add some other views you can add them to a custom Layout without the Alert Dialog. So lets create a LinearLayout and set its orientation as Vertical.

LinearLayout diagLayout = new LinearLayout(this);
diagLayout.setOrientation(LinearLayout.VERTICAL);

5. Now lets create a TextView and set its text using setText() and add attributes like padding, gravity and setTextSIze using setPadding(), setGravity() and setTextView() respectively.

TextView text = new TextView(this); text.setText("Another text view");
text.setPadding(10, 10, 10, 10);
text.setGravity(Gravity.CENTER);
text.setTextSize(20);
