ActionBar tabs set dynamic width according to scre

Question

I have 5 tabs in all. This is how I am adding them :

for (int i = 0; i < tabs.length; i++) {

                if (i == 0) {
                    actionBar.addTab(
                            actionBar.newTab()
                                    .setText(null)
                                    .setIcon(R.drawable.activity)
                                    .setTabListener(this));
                } else if (i == 1) {
                    actionBar.addTab(
                            actionBar.newTab()
                                    .setText(null)
                                    .setIcon(R.drawable.group)
                                    .setTabListener(this));
                } else if (i == 2) {
                    actionBar.addTab(
                            actionBar.newTab()
                                    .setText(null)
                                    .setIcon(R.drawable.message)
                                    .setTabListener(this));
                } else if(i == 3){
                    actionBar.addTab(
                            actionBar.newTab()
                                    .setText(null)
                                    .setIcon(R.drawable.notification)
                                    .setTabListener(this));
                }
                else
                {
                    actionBar.addTab(
                            actionBar.newTab()
                                    .setText(null)
                                    .setIcon(R.drawable.hamburger)
                                    .setTabListener(this));
                }  

I tried this solution but this sets the width of the tab icon and not the tab itself.

Following are the styles I have applied :

App theme :

<style name="CustomActionBarTheme" parent="Theme.AppCompat.Light">
        <item name="android:windowActionBarOverlay">true</item>
        <item name="android:actionBarTabStyle">@style/actionBarTabBarStyle</item>
        <item name="android:actionBarStyle">@style/MyActionBar</item>
    </style>  

 <style name="actionBarTabBarStyle" parent="@style/Widget.AppCompat.ActionBar.TabView">
        <item name="android:paddingLeft">1dp</item>
        <item name="android:paddingRight">1dp</item>
        <item name="android:minWidth">10dp</item>
        <item name="android:maxWidth">15dp</item>
        <item name="android:showDividers">none</item>
    </style>  

I also tried using customView for the tab but it didn't work.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/tabItemLayout"
    android:gravity="center"
    android:layout_width="wrap_content" android:layout_height="match_parent">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:adjustViewBounds="true"
        android:id="@+id/imageViewTab" />
</LinearLayout>

The tabs are too wide and the tabBar is sliding. How can I make the tabs take dynamic width as per the screen width without the sliding effect. i.e. all tabs should fit in the screen width and should be of equal width.

There are 4 tabs visible here. The tabBar is scrollable so the fifth tab appears on scrolling which I don't want.

Answer 1

Use the following code for changing the size of tab and making tabs fit within the screenwidth. Make sure your are using the Custom View

DisplayMetrics displaymetrics = new DisplayMetrics();
           getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
           int screenWidth = displaymetrics.widthPixels;          
           final View tabView = actionBar.getTabAt(0).getCustomView();
           final View tabContainerView = (View) tabView.getParent();
           final int tabPadding = tabContainerView.getPaddingLeft() + tabContainerView.getPaddingRight();
           final int tabs = actionBar.getTabCount();
           for(int i=0 ; i < tabs ; i++) {
               View tab = actionBar.getTabAt(i).getCustomView();
          LinearLayout tabItemLayout = (LinearLayout) tab.findViewById(R.id.tabItemLayout);
          tabItemLayout.setLayoutParams(new LayoutParams(screenWidth/tabs-tabPadding-1, LayoutParams.WRAP_CONTENT));
          }

Answer 2

Tab view width is based on content/yourImage size, so to make tab view width smaller, we have to control the content/Image size. You can do this by putting ImageView inside FrameLayout, for example your customView can be:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:id="@+id/tabItemLayout"
   android:gravity="center"
   android:layout_width="wrap_content" android:layout_height="match_parent">

   <FrameLayout
      android:layout_width="48dp"
      android:layout_height="48dp"
      android:layout_centerInParent="true"
      >

    <ImageView
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:adjustViewBounds="true"
      android:layout_gravity="center"
      android:gravity="center"
      android:id="@+id/imageViewTab" />

   </FrameLayout> 

</RelativeLayout>

and custom style for tab:

<style name="AppTheme" parent="@style/Theme.AppCompat.Light">

             ... ...
    <item name="actionBarTabStyle">@style/ActionBarTabStyle</item>

</style>

<style name="ActionBarTabStyle" parent="@style/Widget.AppCompat.Base.ActionBar.TabView">
   <item name="android:paddingLeft">0dp</item>
   <item name="android:paddingRight">0dp</item>
   <item name="android:paddingTop">0dp</item>
   <item name="android:paddingBottom">0dp</item>
</style>

For FrameLayout size with 24dp:

For FrameLayout size with 40dp

As you're trying to achieve tabs on Actionbar which fits to width of device, one can use PagerSlidingTabStrip or SlidingTabLayout which gives you more flexibility in achieving tabs and its related Fragment with ViewPager which gives your Uix more efficient and user friendly touch.

Here I'm showing how to achieve it using PagerSlidingTabStrip

PagerSlidingTabStrip.java : Your Custom Tab View

public class PagerSlidingTabStrip extends HorizontalScrollView {

    public interface IconTabProvider {
        public int getPageIconResId(int position);
    }

    // @formatter:off
    private static final int[] ATTRS = new int[] { android.R.attr.textSize,
            android.R.attr.textColor };
    // @formatter:on

    private LinearLayout.LayoutParams defaultTabLayoutParams;
    private LinearLayout.LayoutParams expandedTabLayoutParams;

    private final PageListener pageListener = new PageListener();
    public OnPageChangeListener delegatePageListener;

    private LinearLayout tabsContainer;
    private ViewPager pager;

    private int tabCount;

    private int currentPosition = 0;
    private float currentPositionOffset = 0f;

    private Paint rectPaint;
    private Paint dividerPaint;

    private int currentPageSelected = 0; // Fix : ICON SELECTOR

    private int indicatorColor = 0xFF666666;
    private int underlineColor = 0x1A000000;
    private int dividerColor = 0x1A000000;

    private boolean shouldExpand = false;
    private boolean textAllCaps = true;

    private int scrollOffset = 52;
    private int indicatorHeight = 8;
    private int underlineHeight = 2;
    private int dividerPadding = 12;
    private int tabPadding = 24;
    private int dividerWidth = 1;

    private int tabTextSize = 12;
    private int tabTextColor = 0xFF666666;
    private Typeface tabTypeface = null;
    private int tabTypefaceStyle = Typeface.BOLD;

    private int lastScrollX = 0;

    private int tabBackgroundResId = R.drawable.background_tab;

    private Locale locale;

    public PagerSlidingTabStrip(Context context) {
        this(context, null);
    }

    public PagerSlidingTabStrip(Context context, AttributeSet attrs) {
        this(context, attrs, 0);
    }

    public PagerSlidingTabStrip(Context context, AttributeSet attrs,
