我有子菜单：
@Override
public boolean onCreateOptionsMenu(Menu menu) {
SubMenu subMenuFile = menu.addSubMenu("Font type");
SubMenu subMenuEdit = menu.addSubMenu("Font size");
subMenuEdit.add(Menu.NONE, IDM_FONT_SIZE, Menu.NONE, "Change size of font");
return super.onCreateOptionsMenu(menu);
}
我想设置他们的字体。我可以做吗？Menu.XML 文件不支持属性 android:typeface="serif"。编译器说：“错误：不允许字符串类型（在'字体'，值为'Arial'）”然后我这样做了：
@Override
public boolean onCreateOptionsMenu(Menu menu) {
SubMenu subMenuFile = menu.addSubMenu("Font type");
for(int i = 0; i < fontFaces.length; ++i) {
subMenuFile.add(Menu.NONE, IDM_FONT_TYPE, Menu.NONE, Html.fromHtml("<b>html</b>"));
}
SubMenu subMenuEdit = menu.addSubMenu("Font size");
subMenuEdit.add(Menu.NONE, IDM_FONT_SIZE, Menu.NONE, "Change size of font");
return super.onCreateOptionsMenu(menu);
}
我已经看到，子菜单支持不同的样式，但应用程序以错误结束。这是日志：
