(Android) Simple tablayout hacky trick to custom text, background and etc

 

 

Above images is where is tried to custom the tablayout to become the shape like that :D The designer design the UI like that and i have to came out a solution to custom it..
Note: I create it by my own. If you have better solution, you can suggest me :D TQ..

Below is the base init to custom tab layout

        Tablayout tabs = (TabLayout)findViewById(R.id.tabs);
        //cast the selected tablayout to viewgroup
        ViewGroup vg = (ViewGroup) tabs.getChildAt(0);
        //count how many tabs in tablayout
        int tabsCount = vg.getChildCount();
        //iterative each tab
        for (int j = 0; j < tabsCount; j++) {
            //Get all element in each tabs and cast to viewgroup
            ViewGroup vgTab = (ViewGroup) vg.getChildAt(j);
            //count the element in each tabs
            int tabChildsCount = vgTab.getChildCount();
            for (int i = 0; i < tabChildsCount; i++) {
                // cast to View
                View tabViewChild = vgTab.getChildAt(i);
            }
        }

How to use
To change the font of the tabs. Just use View instanceOf TextView

        // using built-in tablayout function to change indicator and text color but limited
        tabs.setTabTextColors(ContextCompat.getColor(this, R.color.md_grey_500), ContextCompat.getColor(this, R.color.white));
        tabs.setSelectedTabIndicatorColor(getResources().getColor(android.R.color.transparent));

Custom Tabs

        // init your font
        Typeface tf = Typeface.createFromAsset(getAssets(), "fonts/knockout-htf49-liteweight.ttf");
        ViewGroup vg = (ViewGroup) tabs.getChildAt(0);
        int tabsCount = vg.getChildCount();
        for (int j = 0; j < tabsCount; j++) {
            ViewGroup vgTab = (ViewGroup) vg.getChildAt(j);
            int tabChildsCount = vgTab.getChildCount();
            for (int i = 0; i < tabChildsCount; i++) {
                View tabViewChild = vgTab.getChildAt(i);
                // Get TextView Element
                if (tabViewChild instanceof TextView) {
                  // change font
                  ((TextView) tabViewChild).setTypeface(tf);
                  // change color
                  ((TextView) tabViewChild).setTextColor(getResources().getColor(R.color.white));
                  // change size
                  ((TextView) tabViewChild).setTextSize(18);
                  // change padding
                  tabViewChild.setPadding(0, 0, 0, 0);
                  //..... etc...
                }
            }
        }

To change background of the tabs

        ViewGroup vg = (ViewGroup) tabs.getChildAt(0);
        int tabsCount = vg.getChildCount();
        for (int j = 0; j < tabsCount; j++) {
            View view = vg.getChildAt(j);
            //change drawable for each tabs
            view.setBackgroundResource(R.drawable.backgroundtabs);

            //if you want to diff drawable for each tabs for example tabs is 4
            //if j == 0    view.setBackgroundResource(R.drawable.backgroundtabs1);  
            //if j == 1    view.setBackgroundResource(R.drawable.backgroundtabs2);
            //if j == 2    view.setBackgroundResource(R.drawable.backgroundtabs3);
            //if j == 3    view.setBackgroundResource(R.drawable.backgroundtabs4);

            ViewGroup vgTab = (ViewGroup) view;
            int tabChildsCount = vgTab.getChildCount();
            for (int i = 0; i < tabChildsCount; i++) {
                View tabViewChild = vgTab.getChildAt(i);
            }
        }

Add listener if you want to track the tab changes

tabs.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
            @Override
            public void onTabSelected(TabLayout.Tab tab) {
                // code what happen when tab is selected  
            }
            @Override
            public void onTabUnselected(TabLayout.Tab tab) {
                // code what happen when tab is unselected
            }
            @Override
            public void onTabReselected(TabLayout.Tab tab) {
                // code what happen when the tab is reselected
            }
        });

To change background of the tablayout

        <android.support.design.widget.TabLayout
          android:layout_height="wrap_content"
          android:layout_width="match_parent"
          android:id="@+id/tabs"
          android:background="@drawable/stripetab"    <-- create stripe background like example image
          app:tabTextAppearance="@style/CustomTabStyle"/>

NOTES
if you want to use scrollable mode ...etc, You need to set the tabs size (i dont know why). If not, it will looks ugly

My case: i hardcode the width to 120dp (you can change it or just calculate by your own for your perfect size)

       int width = 120; // width - width of tabs 
       int tabsize = 120 * tabcount; // tabcount - number of tabs
       ViewGroup vgTab = (ViewGroup) vg.getChildAt(j);
       if (sizeScreen() < tabsize) 
           vgTab.getLayoutParams().width = dpToPx(120);

       public int dpToPx(int dp) {
           DisplayMetrics displayMetrics = getResources().getDisplayMetrics();
           return Math.round(dp * (displayMetrics.xdpi / DisplayMetrics.DENSITY_DEFAULT));
       }

       public int sizeScreen(){
           return (int)((Resources.getSystem().getDisplayMetrics().widthPixels)/ Resources.getSystem().getDisplayMetrics().density);
       }

This is example of what im doing

    private void setupTabLayout(final TabLayout tabs) {
        tabs.setTabTextColors(ContextCompat.getColor(this, R.color.md_grey_500), ContextCompat.getColor(this, R.color.white));
        tabs.setSelectedTabIndicatorColor(getResources().getColor(android.R.color.transparent));

        if (sizeScreen()<tabsize){
            tabs.setTabMode(TabLayout.MODE_SCROLLABLE);
            tabs.setTabGravity(TabLayout.GRAVITY_FILL);
        }
        else{
            tabs.setTabMode(TabLayout.MODE_FIXED);
            tabs.setTabGravity(TabLayout.GRAVITY_FILL);
        }

        // CHANGE TAB TEXT FONT
        Typeface tf = Typeface.createFromAsset(getAssets(), "fonts/knockout-htf49-liteweight.ttf");
        ViewGroup vg = (ViewGroup) tabs.getChildAt(0);
        int tabsCount = vg.getChildCount();
        for (int j = 0; j < tabsCount; j++) {
            ViewGroup vgTab = (ViewGroup) vg.getChildAt(j);

            if (j==0){
                View view = vg.getChildAt(j);
                view.setBackgroundResource(R.drawable.backgroundtabs);
            }

            if (sizeScreen()<tabsize) {
                vgTab.getLayoutParams().width = dpToPx(120);
            }

            int tabChildsCount = vgTab.getChildCount();
            for (int i = 0; i < tabChildsCount; i++) {
                View tabViewChild = vgTab.getChildAt(i);
                if (tabViewChild instanceof TextView) {
                    ((TextView) tabViewChild).setTypeface(tf);
                    ((TextView) tabViewChild).setTextSize(18);
                    ((TextView) tabViewChild).setAllCaps(true);
                    ((TextView) tabViewChild).setSingleLine(true);
                    //set the text to marquee if text longer than tabs size
                    ((TextView) tabViewChild).setEllipsize(TextUtils.TruncateAt.MARQUEE);
                    ((TextView) tabViewChild).setMarqueeRepeatLimit(100);
                    if (j==0){
                        tabViewChild.setPadding(0, 0, 0, 0);
                    }
