如何在使用 ViewPager 滑动选项卡时更改选项卡指示器颜色和文本颜色

Question

这是我的代码。如何在此Java类中添加选项卡指示器颜色和文本颜色？

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
        actionBar  = getActionBar();
        actionBar.setDisplayShowHomeEnabled(false);  // hides action bar icon
        actionBar.setDisplayShowTitleEnabled(false); // hides action bar title
        LayoutInflater mInflater = LayoutInflater.from(this);
     mCustomView = mInflater.inflate(R.layout.custom_menu, null);
        i = (ImageButton)mCustomView.findViewById(R.id.imageButton);
        actionBar.setDisplayShowCustomEnabled(true);
    e = (EditText)mCustomView. findViewById(R.id.editText1);
    e.setVisibility(mCustomView.INVISIBLE);

        TabAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
        Tab = (ViewPager)findViewById(R.id.pager);

        Tab.setOnPageChangeListener(
                new ViewPager.SimpleOnPageChangeListener() {
                    @Override
                    public void onPageSelected(int position) {
                        actionBar = getActionBar();
                        actionBar.setSelectedNavigationItem(position); 
                        }
                });

        Tab.setAdapter(TabAdapter);
     //   Tab.showContextMenu();
        actionBar = getActionBar();
        //Enable Tabs on Action Bar
      actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
                // set background for action bar tab
        actionBar.setStackedBackgroundDrawable(new ColorDrawable(Color.parseColor("#FFFFFF")));       
        actionBar.show();
        ActionBar.TabListener tabListener = new ActionBar.TabListener(){
            @Override
            public void onTabReselected(android.app.ActionBar.Tab tab,
                    FragmentTransaction ft) {
            }
            @Override
             public void onTabSelected(ActionBar.Tab tab, FragmentTransaction ft) {  
                Tab.setCurrentItem(tab.getPosition());


            }
            @Override
            public void onTabUnselected(android.app.ActionBar.Tab tab,
                    FragmentTransaction ft) {
                // TODO Auto-generated method stub
            }};
            //Add New Tab
            actionBar.addTab(actionBar.newTab().setText("SPOTLIGHT").setTabListener(tabListener));
            actionBar.addTab(actionBar.newTab().setText("WHAT'S NEW").setTabListener(tabListener));
            actionBar.addTab(actionBar.newTab().setText("HOT ITEMS").setTabListener(tabListener));
    }
}

您可以创建一个选项卡布局，其中每个选项卡都有一个自定义文本视图，并使用您选择的任何颜色将该选项卡添加到选项卡布局中

View customView = LayoutInflater.from(getContext()).inflate(R.layout.tab_text, null); 
addTab(newTab().setCustomView(customView));
