How to Show Menu Item Icon Without Tint Color in BottomNavigationView
Understanding the Issue
BottomNavigationView, a popular Android component for navigation, often applies a tint color to its menu icons. This can sometimes clash with your app’s design, especially when you desire a specific icon color. This article will guide you on how to display menu icons without the tint color.
Methods to Remove Tint Color
1. Using Drawable Resources
- Create Custom Drawables: Design your menu icons with the desired color in a vector drawable or image format.
- Set Drawables in Menu: In your menu resource file (e.g., `menu/bottom_nav_menu.xml`), assign these custom drawables to the menu items.
<item
android:id="@+id/menu_item_home"
android:icon="@drawable/home_icon"
android:title="@string/home" />
2. Using a Color Filter
- Set Color Filter: Use a color filter on your icon drawable to override the tint color.
- Apply in Code: Apply the color filter to the menu icons programmatically within your activity or fragment.
import android.graphics.Color;
// ...
BottomNavigationView bottomNavigationView = findViewById(R.id.bottom_nav);
Menu menu = bottomNavigationView.getMenu();
for (int i = 0; i < menu.size(); i++) {
MenuItem item = menu.getItem(i);
item.getIcon().setColorFilter(Color.WHITE, PorterDuff.Mode.SRC_ATOP);
}
Comparison of Methods
| Method | Pros | Cons |
|---|---|---|
| Drawable Resources | – Clear control over icon colors. – Easier for static icons. |
– Requires creating separate drawable resources. – Less flexible for dynamic color changes. |
| Color Filter | – Dynamically adjust colors. – Can be applied with code. |
– Requires more code. – Potentially more complex for intricate designs. |
Important Considerations
- Design Consistency: Ensure your icon colors match the overall app design.
- Accessibility: Use sufficient contrast between icons and backgrounds for accessibility.
- Performance: If using many icons, optimize them for size and complexity.
Conclusion
By utilizing either custom drawables or a color filter, you can successfully remove the tint color from BottomNavigationView icons and achieve the desired appearance for your app.
