You have to use this TabLayoutMediator that mimics tabLayout.setupWithViewPager() and sets up the ViewPager2 with Tablayout. Otherwise, you will have to write your own adapter that will combine both parties. Its code will look like this in Kotlin TabLayoutMediator(tabLayout, viewPager) { tab, position -> tab.text = tabTitles[position] }.attach()
I found a way that can be easy. viewPager = (ViewPager) findViewById(R.id.viewpager); setupViewPager(viewPager); tabLayout = (TabLayout) findViewById(R.id.tabs); tabLayout.setupWithViewPager(viewPager); tabLayout.setOnTabSelectedListener( new TabLayout.ViewPagerOnTabSelectedListener(viewPager) { @Override public void onTabSelected(TabLayout.Tab tab) { super.onTabSelected(tab); int tabIconColor = ContextCompat.getColor(context, R.color.tabSelectedIconColor); tab.getIcon().setColorFilter(tabIconColor, PorterDuff.Mode.SRC_IN); } @Override public void onTabUnselected(TabLayout.Tab tab) { super.onTabUnselected(tab); int tabIconColor = ContextCompat.getColor(context, R.color.tabUnselectedIconColor); tab.getIcon().setColorFilter(tabIconColor, PorterDuff.Mode.SRC_IN); } @Override public void … Read more
UPDATE FOR DESIGN LIBRARY 23.2.0+ The original answer doesn’t work with design library 23.2.0 or later. Thanks for @fahmad6 pointed out in comment, in case someone missed that comment, I’ll put it here. You need to set both textAllCaps and android:textAllCaps to false to disable all capitalize setting. <style name=”MyCustomTextAppearance” parent=”TextAppearance.Design.Tab”> <item name=”textAllCaps”>false</item> <item name=”android:textAllCaps”>false</item> … Read more
<style name=”MineCustomTabText” parent=”TextAppearance.Design.Tab”> <item name=”android:textSize”>16sp</item> </style> Use is in TabLayout like this <android.support.design.widget.TabLayout app:tabTextAppearance=”@style/MineCustomTabText” … />
If you are using TabLayout and you want to change the font you have to add a new for loop to the previous solution like this: private void changeTabsFont() { ViewGroup vg = (ViewGroup) tabLayout.getChildAt(0); int tabsCount = vg.getChildCount(); for (int j = 0; j < tabsCount; j++) { ViewGroup vgTab = (ViewGroup) vg.getChildAt(j); int … Read more
What finally worked for me is similar to what @如果我是DJ suggested, but the tabBackground should be in the layout file and not inside the style, so it looks like: res/layout/somefile.xml: <android.support.design.widget.TabLayout …. app:tabBackground=”@drawable/tab_color_selector” … /> and the selector res/drawable/tab_color_selector.xml: <?xml version=”1.0″ encoding=”utf-8″?> <selector xmlns:android=”http://schemas.android.com/apk/res/android”> <item android:drawable=”@color/tab_background_selected” android:state_selected=”true”/> <item android:drawable=”@color/tab_background_unselected”/> </selector>
All we need are: ViewPager, TabLayout and 2 drawables for selected and default dots. Firstly, we have to add TabLayout to our screen layout, and connect it with ViewPager. We can do this in two ways: Nested TabLayout in ViewPager <androidx.viewpager.widget.ViewPager android:id=”@+id/photos_viewpager” android:layout_width=”match_parent” android:layout_height=”match_parent”> <com.google.android.material.tabs.TabLayout android:layout_width=”match_parent” android:layout_height=”wrap_content”/> </androidx.viewpager.widget.ViewPager> In this case TabLayout will be automatically … Read more
A “simpler” answer borrowed from Kaizie would just be adding app:tabMaxWidth=”0dp” in your TabLayout xml: <android.support.design.widget.TabLayout android:layout_width=”match_parent” android:layout_height=”wrap_content” app:tabMaxWidth=”0dp” app:tabGravity=”fill” app:tabMode=”fixed” />
If you know the index of the tab you want to select, you can do it like so: TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs); TabLayout.Tab tab = tabLayout.getTabAt(someIndex); tab.select(); This technique works even if you’re using the TabLayout by itself without a ViewPager (which is atypical, and probably bad practice, but I’ve seen it done).
