Projenizde yukarıdaki sınıfı kullanmaktan çekinmeyin. Örneğin, kullanıcılarınıza yazı tipi aileleri arasından seçim yapabilir ve yazı tiplerini tercihlerine göre ayarlayabilirsiniz.
Tamamlanmamış küçük bir örnek:
final List<FontListParser.SystemFont> fonts = FontListParser.safelyGetSystemFonts();
String[] items = new String[fonts.size()];
for (int i = 0; i < fonts.size(); i++) {
items[i] = fonts.get(i).name;
}
new AlertDialog.Builder(this).setSingleChoiceItems(items, -1, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
FontListParser.SystemFont selectedFont = fonts.get(which);
// TODO: do something with the font
Toast.makeText(getApplicationContext(), selectedFont.path, Toast.LENGTH_LONG).show();
}
}).show();
