升级到最新的支持库'28 .0.0-alpha1'后,我无法在BottomNavigationView
中禁用移位模式,即BottomNavigationItemView.setShiftingMode()
方法不再可用。

我使用this方法来禁用移位模式。
如果有人能够了解最新版本中的某些内容是否发生了变化,或者这是一个错误还是其他什么,我们将非常感激。
找到了答案。在支持库28.0.0-alpha1中,我们现在可以使用以下任何方法添加标签(删除移位模式):
XML:
<android.support.design.widget.BottomNavigationView
.
.
.
app:labelVisibilityMode="labeled" />
码:
mBottomNavigationView.setLabelVisibilityMode(LabelVisibilityMode.LABEL_VISIBILITY_LABELED);
要么:
@SuppressLint("RestrictedApi")
public static void removeNavigationShiftMode(BottomNavigationView view) {
BottomNavigationMenuView menuView = (BottomNavigationMenuView) view.getChildAt(0);
menuView.setLabelVisibilityMode(LabelVisibilityMode.LABEL_VISIBILITY_LABELED);
menuView.buildMenuView();
}
