自定义mikepenz Material Drawer：替换用户列表为用户所属对象展示

Got it, let's sort this out for you. The core idea is to separate your fixed user profile from the selectable vehicle profiles in the AccountHeader—this way clicking a vehicle won't replace the user's avatar, while still updating the displayed vehicle info. Here's how to adjust your code step by step:

关键修改思路 #

• Mark the current logged-in user as a non-selectable fixed profile to lock their avatar in place (no replacement when clicking other items)
• Replace the original user list (spots 4 and 5) with the user's vehicle list as selectable profiles
• Handle the profile selection event to update the displayed vehicle details (spots 2 and 3) while keeping the user's avatar intact

public class MikePenz {
    private static Drawer drawer;
    private static AccountHeader accountHeader;
    AccountHeader.OnAccountHeaderSelectionViewClickListener mOnAccountHeaderSelectionViewClickListener;
    View mAccountSwitcherArrow;
    Activity activity;

    public static void mikepenz(final Activity activity, Toolbar toolbar) {
        // 1. Create fixed logged-in user profile (non-selectable to protect avatar)
        ProfileDrawerItem currentUserProfile = new ProfileDrawerItem()
                .withName("pejman ghorbany") // Spot 1: User name
                .withEmail("pejman.gh66@gmail.com")
                .withIcon(R.drawable.ic_build_black_24dp) // Spot 1: User avatar
                .withSelectable(false); // Critical: Prevent this profile from being selected

        // 2. Create vehicle list to replace original user profiles (spots 4 & 5)
        List<IProfile> vehicleProfiles = new ArrayList<>();
        vehicleProfiles.add(new ProfileDrawerItem()
                .withName("Vehicle A") // Shows in spot 2 when selected
                .withEmail("License:京A12345") // Shows in spot 3 when selected
                .withIcon(R.mipmap.car_icon_1));

核心代码解释 #

• Fixed User Profile: Using withSelectable(false) ensures the logged-in user's profile can't be selected, so their avatar (spot 1) never gets replaced.
• Vehicle List Replacement: The original user profiles are swapped out for vehicle profiles, which appear in the dropdown list (spots 4 and 5).
• Selection Handling: When a vehicle is selected, we create a new profile that uses the vehicle's name/email (for spots 2 and 3) but reuses the original user's avatar—this keeps the user's icon intact while updating the vehicle info.
• AccountHeader Reference: Saving the headerResult lets us dynamically update the header display when a vehicle is selected.
