Android NavigationView: reduce space between icon and text and `itemBackground` not working

To reduce the space between the icon and text in a NavigationView item and address the issue with itemBackground, you can use a custom layout for the navigation items. This way, you have more control over the item layout and can adjust spacing and backgrounds as needed.

Here's an example:

Step 1: Create a Custom Layout for NavigationView Items

Create a new layout resource file (e.g., custom_nav_item.xml) in your res/layout folder:

<!-- res/layout/custom_nav_item.xml --> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal" android:paddingStart="16dp" android:paddingEnd="16dp" android:paddingTop="8dp" android:paddingBottom="8dp" android:gravity="center_vertical"> <!-- Adjust padding and gravity as needed --> <ImageView android:id="@+id/navigation_icon" android:layout_width="24dp" android:layout_height="24dp" android:layout_gravity="center_vertical" android:layout_marginEnd="8dp" <!-- Adjust the margin as needed --> android:tint="?android:textColorSecondary"/> <!-- Optional tint for the icon --> <TextView android:id="@+id/navigation_title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textAppearance="?android:textAppearanceSubtitle1" android:textColor="?android:textColorSecondary"/> </LinearLayout>

Step 2: Use the Custom Layout in NavigationView

In your NavigationView in your activity layout (e.g., activity_main.xml), set the app:headerLayout attribute to use the custom layout:

<!-- activity_main.xml --> <com.google.android.material.navigation.NavigationView android:id="@+id/navigationView" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_gravity="start" app:headerLayout="@layout/custom_nav_header" app:menu="@menu/nav_menu"/>

Step 3: Apply the Custom Layout in Code

In your activity or fragment, find the NavigationView and set a custom HeaderView:

// In your activity or fragment val navigationView: NavigationView = findViewById(R.id.navigationView) val headerView = navigationView.getHeaderView(0) // Customize header view as needed // For example, change the background color: headerView.setBackgroundResource(R.drawable.your_custom_background) // Set the custom layout for navigation items navigationView.menu.forEach { val menuItem = it val actionView = layoutInflater.inflate(R.layout.custom_nav_item, null) val icon = actionView.findViewById<ImageView>(R.id.navigation_icon) val title = actionView.findViewById<TextView>(R.id.navigation_title) icon.setImageDrawable(menuItem.icon) title.text = menuItem.title menuItem.actionView = actionView menuItem.setOnMenuItemClickListener { // Handle item click as needed true } }

In this example, custom_nav_item.xml is a custom layout for navigation items, and it allows you to control the spacing between the icon and text. Adjust the padding, margins, and other attributes to meet your design requirements.

Regarding the itemBackground issue, ensure that the background drawable you're using for the NavigationView items (@drawable/your_custom_background in the example) has the proper states defined, such as android:state_pressed and android:state_checked. This ensures that the background changes appropriately based on user interactions.
