解决方案

添加.setIcon（resources.getDrawable（DrawableIDHere））在你的for循环，也改变你的for循环了一下。

  //添加标签
的for（int i = 0; I＆LT; tabs.length;我++）
{
actionBar.addTab（actionBar.newTab（）的setText（标签[I]）
                         .setIcon（resources.getDrawable（图标[i]））
                         .setTabListener（本））;
} // ENDFOR
 

另外，不要忘了把正确绘制的ID在你的图标阵！

I am downloading the code from here i want to dispaly tabs with icon how can posssible please help me.

 public class MainActivity extends FragmentActivity implements
            ActionBar.TabListener {

    private ViewPager viewPager;
    private TabsPagerAdapter mAdapter;
    private ActionBar actionBar;
    // Tab titles
    private String[] tabs = { "Text", "Photo", "Record" ,"Tag"};


    @TargetApi(Build.VERSION_CODES.HONEYCOMB)
    @SuppressLint("NewApi")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Initilization
        viewPager = (ViewPager) findViewById(R.id.pager);
        actionBar = getActionBar();
        mAdapter = new TabsPagerAdapter(getSupportFragmentManager());

        final int[] ICONS = new int[] {
            R.drawable.ic_launcher,
            R.drawable.ic_launcher,
            R.drawable.ic_launcher,
            R.drawable.ic_launcher,
    };

        viewPager.setAdapter(mAdapter);
        actionBar.setHomeButtonEnabled(false);
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);        

        // Adding Tabs
        for (String tab_name : tabs) {
            actionBar.addTab(actionBar.newTab().setText(tab_name)
                    .setTabListener(this));


        }

        /**
         * on swiping the viewpager make respective tab selected
         * */
        viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {

            @Override
            public void onPageSelected(int position) {
                // on changing the page
                // make respected tab selected
                actionBar.setSelectedNavigationItem(position);
            }

            @Override
            public void onPageScrolled(int arg0, float arg1, int arg2) {
            }

            @Override
            public void onPageScrollStateChanged(int arg0) {
            }
        });
    }

    @Override
    public void onTabReselected(Tab tab, FragmentTransaction ft) {
    }

    @Override
    public void onTabSelected(Tab tab, FragmentTransaction ft) {
        // on tab selected
        // show respected fragment view
        viewPager.setCurrentItem(tab.getPosition());
    }

    @Override
    public void onTabUnselected(Tab tab, FragmentTransaction ft) {
    }

}

解决方案

Add .setIcon(resources.getDrawable(DrawableIDHere)) in your for loop, and also alter your for loop a bit.

// Adding Tabs
for (int i=0; i < tabs.length; i++)
{
actionBar.addTab(actionBar.newTab().setText(tabs[i])
                         .setIcon(resources.getDrawable(ICONS[i]))
                         .setTabListener(this));
}//endfor

Also, don't forget to put the right drawable ID's in your ICONS array!
