How to show appropriate icon on dialog box

I have an application that allows the users to delete video files. When I press the delete button, I am using

DialogInterface.OnClickListener dialogClickListener = new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
switch (which) {
case DialogInterface.BUTTON_POSITIVE:
// mycode........
break;
case DialogInterface.BUTTON_NEGATIVE:
// mycode.....
break;
}
}
};


But this message doesn't have a warning or delete icon as we see in android devices. Can anyone help me in getting those icons or using any other alert dialogs that can show those icons?

Answer

I tend to use AlertDialog.Builder like they show in the official doc example

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Are you sure you want to exit?")
   .setCancelable(false)
   .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog, int id) {
            MyActivity.this.finish();
       }
   })
   .setNegativeButton("No", new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog, int id) {
            dialog.cancel();
       }
   })
   //Set your icon here
   .setTitle("Alert!")
   .setIcon(R.drawable.icon);
AlertDialog alert = builder.create();
 alert.show();//showing the dialog

As for the actual icon look inside your sdk folder/platforms/android version #/data/res/drawable-mdpi or something
