Hi,

In android, is it possible to customize the header layout (the icon + a text) layout of a dialog? Or I can just set the string value of the title text?

Thank you.

the original Dialog class seems to lack the ability to set an icon, but you can easily extend AlertDialog and set a custom view (the same you would use for your Dialog instance), you just need something like this

 class MyDialog extends AlertDialog {
     public MyDialog(Context ctx) {
        super(ctx);
        LayoutInflater factory = LayoutInflater.from(context);
        View view = factory.inflate(R.layout.dialog_layout, null);
        setView(view);
        setTitle("MyTitle");
        setIcon(R.drawable.myicon);
     }
 }

It's possible to change the header of the Dialog if you set a custom layout for both the dialog and the header. I've only ever used this method to remove the header entirely, but this ought to work for a custom header:

dialog = new Dialog(context);
Window window = dialog.getWindow();
window.requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
dialog.setContentView(R.layout.my_dialog_layout);
window.setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.my_custom_header);

This is all a tad more complicated (as you have to setup the dialog's layout as well) but it's easier than subclassing Dialog.
