Java - How to change the color of icon of the selected tab of TabLayout?

To change the color of the icon of the selected tab in a TabLayout in Android using Java, you can create a custom tab layout with a custom layout for each tab. Then, you can programmatically change the color of the icon based on the selected state of the tab.

Here's how you can do it:

  1. First, create a custom layout for your tab with an ImageView for the icon:
<!-- tab_custom_layout.xml --> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="vertical"> <ImageView android:id="@+id/tab_icon" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" /> <!-- Add other views if needed, like TextView for title --> </LinearLayout>
  1. Use this custom layout for your tabs when setting up the TabLayout:
// Set up TabLayout TabLayout tabLayout = findViewById(R.id.tab_layout); tabLayout.setupWithViewPager(viewPager); // Set custom view for each tab for (int i = 0; i < tabLayout.getTabCount(); i++) { TabLayout.Tab tab = tabLayout.getTabAt(i); if (tab != null) { tab.setCustomView(R.layout.tab_custom_layout); // You can also set title or other views here if needed } }
  1. Finally, programmatically change the color of the icon based on the selected state of the tab:
// Listen for tab selection change tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() { @Override public void onTabSelected(TabLayout.Tab tab) { // Get the custom view for the selected tab View customView = tab.getCustomView(); if (customView != null) { // Find the ImageView and change its color ImageView iconImageView = customView.findViewById(R.id.tab_icon); if (iconImageView != null) { iconImageView.setColorFilter(ContextCompat.getColor(context, R.color.selected_tab_icon_color), PorterDuff.Mode.SRC_IN); } } } @Override public void onTabUnselected(TabLayout.Tab tab) { // You can reset the color here if needed } @Override public void onTabReselected(TabLayout.Tab tab) { // Optional: Handle reselection of the tab } });

In this code:

  • We use a custom layout tab_custom_layout.xml for each tab, which includes an ImageView for the icon.
  • We set this custom layout for each tab using tab.setCustomView(R.layout.tab_custom_layout).
  • We listen for tab selection changes using tabLayout.addOnTabSelectedListener() and programmatically change the color of the icon based on the selected state using ImageView.setColorFilter().
  • Don't forget to define the color resource selected_tab_icon_color in your res/values/colors.xml file.

Adjust the icon color, layout, and other properties as needed for your application.

    for (int i = 0; i < tabLayout.getTabCount(); i++) { TabLayout.Tab tab = tabLayout.getTabAt(i); if (tab != null) { Drawable icon = tab.getIcon(); if (icon != null) { icon.setColorFilter(getResources().getColorStateList(R.color.tab_icon_color), PorterDuff.Mode.SRC_IN); } } }
