android center align the selected tab in tablayout

I took a look into TabLayout and tabContentStart only sets padding for its first child -> SlidingTabStrip, so I set it manually on both sides: public class CenteringTabLayout extends TabLayout { public CenteringTabLayout(Context context) { super(context); } public CenteringTabLayout(Context context, AttributeSet attrs) { super(context, attrs); } public CenteringTabLayout(Context context, AttributeSet attrs, int defStyleAttr) { super(context, … Read more

Different tab width for TabLayout

You need to lower the weight of the LinearLayout of the corresponding tab. LinearLayout layout = ((LinearLayout) ((LinearLayout) tabLayout.getChildAt(0)).getChildAt(YOUR_TAB_NUMBER)); LinearLayout.LayoutParams layoutParams = (LinearLayout.LayoutParams) layout.getLayoutParams(); layoutParams.weight = YOUR_WEIGHT; // e.g. 0.5f layout.setLayoutParams(layoutParams); Hope that helps!

Can a custom view be used as a TabItem?

In certain cases, instead of the default tab view we may want to apply a custom XML layout for each tab. To achieve this, iterate over all the TabLayout.Tabs after attaching the sliding tabs to the pager: public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // Get the ViewPager … Read more

How to set android TabLayout in the bottom of the screen?

I believe I have the best simple fix. Use a LinearLayout and set the height of the viewpager to be 0dp with a layout_weight=”1″. Make sure the LinearLayout has an orientation of vertical and that the viewpager comes before the TabLayout. Here is what mines looks like: <LinearLayout xmlns:android=”http://schemas.android.com/apk/res/android” xmlns:tools=”http://schemas.android.com/tools” android:layout_width=”match_parent” android:layout_height=”match_parent” tools:context=”.MainActivity” android:orientation=”vertical”> <include … Read more

Change the font of tab text in android design support TabLayout

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

android:textAllCaps=”false” not working for TabLayout design Support

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

Disable TabLayout

I had the same problem and I solved it disabling touch event on tabs with the following code: LinearLayout tabStrip = ((LinearLayout)mTabLayout.getChildAt(0)); for(int i = 0; i < tabStrip.getChildCount(); i++) { tabStrip.getChildAt(i).setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { return true; } }); }

How to use TabLayout with ViewPager2 in Android

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()

TabLayout tab selection

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).

ViewPager + RecyclerView issue in android

I see a lot of problems with your code, but let’s get your UI displaying the subcategories since that’s your main concern. Change the getItem in your adapter to this: @Override public Fragment getItem(int position) { ArrayList<SubcategoryModel> subcategories = filelist.get(position).getItems(); Log.v(“adapter”, “getitem” + String.valueOf(position)+subcategories.size()); return FirstFragment.create(position,subcategories); } What caused the problem: Let’s focus on ArrayList<SubcategoryModel> … Read more
