我想添加一個字體到textView。我有以下代碼片段，但我不確定如何將其適用於下面的代碼。有人能幫我嗎？如何將自定義字體添加到此TextView？
代碼片斷我想融入我的程序：
Typeface myTypeface = Typeface.createFromAsset(getAssets(), "fonts/Xcelsion.ttf"); // getActivity().getAssets()
TextView myTextView = (TextView)findViewById(R.id.text_view);
myTextView.setTypeface(myTypeface); //
計劃我想將字體添加到：
