我试图将所有图标居中,我已经通过使用以下代码禁用了切换模式:

/**
 * This is done to remove the shift animation introduced by Android on the bottom navigation view
 * https://stackoverflow.com/a/41690461/4243027
 */
@SuppressLint("RestrictedApi")
public static void disableShiftMode(BottomNavigationView view) {
    BottomNavigationMenuView menuView = (BottomNavigationMenuView) view.getChildAt(0);
    try {
        Field shiftingMode = menuView.getClass().getDeclaredField("mShiftingMode");
        shiftingMode.setAccessible(true);
        shiftingMode.setBoolean(menuView, false);
        shiftingMode.setAccessible(false);
        for (int i = 0; i < menuView.getChildCount(); i++) {
            BottomNavigationItemView item = (BottomNavigationItemView) menuView.getChildAt(i);
            //noinspection RestrictedApi
            item.setShiftingMode(false);
            item.setPadding(0,15,0,0);
            // set once again checked value, so view will be updated
            //noinspection RestrictedApi
            item.setChecked(item.getItemData().isChecked());
        }
    } catch (NoSuchFieldException e) {
        Log.e("BNVHelper", "Unable to get shift mode field", e);
    } catch (IllegalAccessException e) {
        Log.e("BNVHelper", "Unable to change value of shift mode", e);
    }
}

并将标题设置为“”

android:title=""

我也尝试过执行以下https://stackoverflow.com/a/40234361/4243027,但是它也不起作用。

我的底部导航视图如下:

Bottom navigation bar

我正在使用implementation "com.android.support:design:27.0.1"

编辑:

正如您在“布局检查器”中所看到的,图标大小相同,为63x63像素,但选中的图标的Y小5像素。

Layout Inspector

从Design Support Library 28.0.0-alpha1开始,您可以使用属性

app:labelVisibilityMode =“未标记”
