AlertDialog




An AlertDialog object represents an Alert Box on the screen.

import android.app.AlertDialog;
import android.content.DialogInterface;


Example:

public void setUpMyAlertYesOrNo()
{
   // prepare the alert box
   alertbox = new AlertDialog.Builder(this);
  
   // set the message to display
   alertbox.setMessage("Update From Web?");
  
   // set a positive/yes button and create a listener
   alertbox.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
     // do something when the button is clicked
     public void onClick(DialogInterface arg0, int arg1) {
     // do whatever
     Toast.makeText(getApplicationContext(), "Your data has been updated.", Toast.LENGTH_SHORT).show();
   }
   });
  
   // set a negative/no button and create a listener
   alertbox.setNegativeButton("No", new DialogInterface.OnClickListener() {
   // do something when the button is clicked
   public void onClick(DialogInterface arg0, int arg1) {
     // Toast.makeText(getApplicationContext(), "'No' button clicked", Toast.LENGTH_SHORT).show();
   }
   });

   // display box
   alertbox.show();
}
