Android中的自定义操作栏？

Question

I have developed an Android application which has 4 TabHost's which are in fragments.

I Know how to customize the ActionBar in MainActivity.

But problem is how can I customize my ActionBar according to the 4 different TabHost's in different Fragment s?

Here is my tabHost code -

public class MainActivity extends Activity {
/** Called when the activity is first created. */

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    ActionBar actionBar = getActionBar();
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);


    /** Creating ANDROID Tab */
    Tab tab = actionBar.newTab()
            //.setText("Android")

            .setTabListener(new CustomTabListener<PlayFragment01>(this, "play", 
    PlayFragment01.class))
            .setIcon(R.drawable.playtabhosticon);

    actionBar.addTab(tab);


    /** Creating APPLE Tab */
    Tab tab1 = actionBar.newTab()
            //.setText("Apple")
            .setTabListener(new CustomTabListener<VenueFragment01>(this, "venu", 
    VenueFragment01.class))
            .setIcon(R.drawable.venutabhosticon);

    actionBar.addTab(tab1);  

    /** Creating APPLE Tab */
    Tab tab3 = actionBar.newTab()
            //.setText("Apple")
            .setTabListener(new CustomTabListener<SocialFragment01>(this, "social", SocialFragment01.class))
            .setIcon(R.drawable.socialtabhosticon);

    actionBar.addTab(tab3);  

    /** Creating APPLE Tab */
    Tab tab4 = actionBar.newTab()
            //.setText("Apple")
            .setTabListener(new CustomTabListener<ActivityFragment01>(this, "activity",         
   ActivityFragment01.class))
            .setIcon(R.drawable.actionbartabhosticon);

    actionBar.addTab(tab4);  



}   
}

Here is my first fragment code -

package in.wptrafficanalyzer.actionbarnavtab;
 /** This is a listfragment class */
 public class PlayFragment01 extends Fragment {

/** An array of items to display in ArrayList */



@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)    
{
    /** Creating array adapter to set data in listview */
    View rootView = inflater.inflate(R.layout.fragment_play, container, false);         
    //new DownloadJSON().execute();

    ActionBar actionBar = getActivity().getActionBar();
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
    getActivity().getActionBar().setBackgroundDrawable(
            new ColorDrawable(Color.parseColor("#0077d1")));
    ActionBar mActionBar = getActivity().getActionBar();
    getActivity().getActionBar().setIcon(
       new ColorDrawable(getResources().getColor(android.R.color.transparent)));    
    mActionBar.setDisplayShowHomeEnabled(true);
    mActionBar.setDisplayShowTitleEnabled(false);
    LayoutInflater mInflater = LayoutInflater.from(this);
    View mCustomView = mInflater.inflate(R.layout.custom_actionbar2, null);
    mActionBar.setCustomView(mCustomView);
    mActionBar.setDisplayShowCustomEnabled(true);

    return rootView;
}
}

Answer 1

您提出的问题不是很清楚，但是您可以使用getActivity().getActionBar()从Fragment中获取ActionBar实例。

Answer 2

ActionBar.setNavigationMode() and TabHost is now deprecated.

The new ToolBar introduced in API-21 is more powerfull.

But since you asked for a solution, here is a simple one from Google SlidingTabLayout : This is like a PagerTabStrip that you can easily customize and works like great.

It works with ViewPager and Fragments of course.

Answer 3

In my point of view ,you should read this ,so that you can get the basic idea for creating a fragment.

http://developer.android.com/guide/components/fragments.html

Try this sample code..this sample code includes 3 tab ,first try to understand this code ,then you can make your own app with 4 tabs

Also try to modify your question ,It is unclear and also it will be good that you post your errors
