I really recommend you to use the Actionbar Style Generator.

With that tool you can easily theme your graphic elements in your toolbar.

put this function and call it to yout Activity and pass tabhost as a parameter

public static void setTabColor(TabHost tabhost) {

            for (int i = 0; i < tabhost.getTabWidget().getChildCount(); i++) {
                tabhost.getTabWidget().getChildAt(i)
                        .setBackgroundResource(R.drawable.header_blank); // unselected
            }
            tabhost.getTabWidget().setCurrentTab(0);
            tabhost.getTabWidget().getChildAt(tabhost.getCurrentTab())
                    .setBackgroundResource(R.drawable.tab_selected_new); // selected
                                                                            // //have
                                                                            // to
                                                                            // change
        }

call this as following way

        setTabColor(tabHost);
        tabHost.setOnTabChangedListener(new OnTabChangeListener() {

            @Override
            public void onTabChanged(String arg0) {

                setTabColor(tabHost);
            }
             });

hope this is useful to you

Style your custom theme like below.

<item name="android:tabWidgetStyle">@android:style/Widget.TabWidget</item>

after that

<style name="Widget.TabWidget">
    <item name="android:textAppearance">@style/TextAppearance.Widget.TabWidget</item>
    <item name="android:ellipsize">marquee</item>
    <item name="android:singleLine">true</item>
</style>  


<style name="TextAppearance.Widget.TabWidget">
    <item name="android:textSize">14sp</item>
    <item name="android:textStyle">normal</item>
    <item name="android:textColor">@android:color/tab_indicator_text</item>
</style>   

Or you can use following code.

 tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.RED);

or

 tabHost.getTabWidget().getChildAt(0).setBackgroundColor(Color.parseColor("#4E4E9C"));

Hope it helps you .

Just add the following 2 attributes in your tab layout.

app:tabSelectedTextColor="@color/color_primary_text"
app:tabTextColor="@color/color_secondary_text"

Whole tablayout in xml looks like below

<android.support.design.widget.TabLayout
android:id="@+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentStart="true"
android:layout_gravity="bottom"
android:background="@color/button_background"
android:fillViewport="true"
app:tabBackground="@drawable/fixed_bottom_button"
app:tabIndicatorColor="@color/color_primary_text"
app:tabMode="fixed"
app:tabSelectedTextColor="@color/color_primary_text"
app:tabTextColor="@color/color_secondary_text" />

回答5:

myTabHost.setOnTabChangedListener(new TabHost.OnTabChangeListener(){
  @Override
  public void onTabChanged(String tabId) {
    int tab = myTabHost.getCurrentTab();
    View view = myTabHost.getTabWidget().getChildAt(tab).setBackgroundColor(Color.CYAN);
  }
});

回答6:

To change tab bar background:

actionBar.setStackedBackgroundDrawable(new ColorDrawable(yourOwnColor)); 

回答7:

Create an selector file which consist your desire color apply on tab xml like below:

 <?xml version="1.0" encoding="utf-8"?>
        <!--

         -->
    <selector xmlns:android="http://schemas.android.com/apk/res/android">

        <!--  Active tab -->
        <item android:state_selected="true" android:state_focused="false"
        android:state_pressed="false" android:drawable="@drawable/dm_tab_highlight" />
        <!--  Inactive tab -->
    <!--    <item android:state_selected="false" android:state_focused="false" -->
    <!-- android:state_pressed="false" android:drawable="@drawable/tabbarbg" /> -->

        <!--  Pressed tab -->
        <item android:state_pressed="true" android:drawable="@drawable/dm_tab_highlight" />


    </selector>

You can use this code and set icon alpha , it look like one is selected and other are disable.

viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
    }

    @Override
    public void onPageSelected(int position) {
        switch (position) {
            case 0:
                tabLayoutUserProfileTabs.getTabAt(0).getIcon().setAlpha(255);
                tabLayoutUserProfileTabs.getTabAt(1).getIcon().setAlpha(128);
                tabLayoutUserProfileTabs.getTabAt(2).getIcon().setAlpha(128);
                tabLayoutUserProfileTabs.getTabAt(3).getIcon().setAlpha(128);
                break;
            case 1:
                tabLayoutUserProfileTabs.getTabAt(0).getIcon().setAlpha(128);
                tabLayoutUserProfileTabs.getTabAt(1).getIcon().setAlpha(255);
                tabLayoutUserProfileTabs.getTabAt(2).getIcon().setAlpha(128);
                tabLayoutUserProfileTabs.getTabAt(3).getIcon().setAlpha(128);
                break;
            case 2:
                tabLayoutUserProfileTabs.getTabAt(0).getIcon().setAlpha(128);
                tabLayoutUserProfileTabs.getTabAt(1).getIcon().setAlpha(128);
                tabLayoutUserProfileTabs.getTabAt(2).getIcon().setAlpha(255);
                tabLayoutUserProfileTabs.getTabAt(3).getIcon().setAlpha(128);
                break;
            case 3:
                tabLayoutUserProfileTabs.getTabAt(0).getIcon().setAlpha(128);
                tabLayoutUserProfileTabs.getTabAt(1).getIcon().setAlpha(128);
                tabLayoutUserProfileTabs.getTabAt(2).getIcon().setAlpha(128);
             tabLayoutUserProfileTabs.getTabAt(3).getIcon().setAlpha(255);
                break;
        }
    }

    @Override
    public void onPageScrollStateChanged(int state) {
    }
});

use this code in order to change the color of selected tab:-

tabLayout.setTabTextColors(Color.parseColor("color_for_unselected_tab"), Color.parseColor("color_for_tab"));
for tab-indicator
 tabLayout.setSelectedTabIndicatorColor(Color.parseColor("#627179")));
