这是我已实施的自定义对话框的代码
final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.custom_dialog);
dialog.setTitle("This is the Title");
TextView text = (TextView) dialog.findViewById(R.id.text);
text.setTypeface(Typeface.createFromAsset(getAssets(),
"fonts/Barkentina.otf"));
我可以轻松更改对话框中文字的字体。但是我该怎么做才能改变对话框标题的字体呢?
