Question

I am developing one application and in which i have to display a five tabs and on each tab i am calling a different activity.And in my last tab i displaying menus.

The main problem is that my activities are called only on tab changed events.when i am clicking on last tab first time it displays a menu and after selecting any menu if i click on that tab again then nothing happens.

So how to solve this kind of problem? is there any other way to do this task?
Any help will be appreciated.Thanks

Here is my code:

public class More extends ActivityGroup{

     Button btn1;
     ExpandableListView elw;
     Context ctx;
     public ListView modeList;
     @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            ctx=this;

           Toast.makeText(More.this,"in more",200).show();
           setContentView(R.layout.more);

           AlertDialog.Builder builder = new AlertDialog.Builder(this);
           builder.setTitle("More Option");

            modeList = new ListView(this);
           String[] stringArray = new String[] { "About", "Settings","Invite By Message","Privacy Policy","Deactivate Account","Exit" };
           ArrayAdapter<String> modeAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, android.R.id.text1, stringArray);
           modeList.setAdapter(modeAdapter);


           builder.setView(modeList);
           final Dialog dialog = builder.create();

           dialog.show();
modeList.setOnItemClickListener(new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
        // TODO Auto-generated method stub
        String item=(String) modeList.getItemAtPosition(position);
        Toast.makeText(More.this,item,200).show();
        switch(position) {
        case 0:
            setContentView(R.layout.about);
            dialog.dismiss();
          TabHost tabHost = welcome.self.getTabHost();
          tabHost.setCurrentTab(4);

              // tabHost.setCurrentTab(4);
            break;
        case 1:
            setContentView(R.layout.settings);
            dialog.dismiss();
            break;
        case 2:
            setContentView(R.layout.messages);
            dialog.dismiss();
            break;
        case 3:
            setContentView(R.layout.policy);
            dialog.dismiss();
            break;
        case 4:
            Toast.makeText(More.this,"Deactivate the Account",200).show();
            dialog.dismiss();
            break;
        default:
             Toast.makeText(More.this,"Exit the application",200).show();
             dialog.dismiss();
             welcome.self.finish();
            }               
    }
});

modeList.setOnItemClickListener(new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
        // TODO Auto-generated method stub
        String item=(String) modeList.getItemAtPosition(position);
        Toast.makeText(More.this,item,200).show();
        switch(position) {
        case 0:
            setContentView(R.layout.about);
            dialog.dismiss();
         // TabHost tabHost = welcome.self.getTabHost();-> Intent abc;

         // tabHost.setCurrentTab(4);---->abc.getClass(More.this , NewClass.class);

              // tabHost.setCurrentTab(4);
            break;
        case 1:
            setContentView(R.layout.settings);
            dialog.dismiss();
            break;
        case 2:
            setContentView(R.layout.messages);
            dialog.dismiss();
            break;
        case 3:
            setContentView(R.layout.policy);
            dialog.dismiss();
            break;
        case 4:
            Toast.makeText(More.this,"Deactivate the Account",200).show();
            dialog.dismiss();
            break;
        default:
             Toast.makeText(More.this,"Exit the application",200).show();
             dialog.dismiss();
             welcome.self.finish();
            }               
    }
});

Now your NewClass.java

public class NewClass extends TabActivit{


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

           setContentView(R.layout.newclass);

Resources ressources = getResources(); 
        TabHost tabHost = getTabHost(); 

        // Android tab
        Intent intentAndroid = new Intent().setClass(this, AndroidActivity.class);
        TabSpec tabSpecAndroid = tabHost
          .newTabSpec("Android")
          .setIndicator("", ressources.getDrawable(R.drawable.icon_android_config))
          .setContent(intentAndroid);

        // Apple tab
        Intent intentApple = new Intent().setClass(this, AppleActivity.class);
        TabSpec tabSpecApple = tabHost
          .newTabSpec("Apple")
          .setIndicator("", ressources.getDrawable(R.drawable.icon_apple_config))
          .setContent(intentApple);

        // Windows tab
        Intent intentWindows = new Intent().setClass(this, WindowsActivity.class);
        TabSpec tabSpecWindows = tabHost
          .newTabSpec("Windows")
          .setIndicator("", ressources.getDrawable(R.drawable.icon_windows_config))
          .setContent(intentWindows);

        // Blackberry tab
        Intent intentBerry = new Intent().setClass(this, BlackBerryActivity.class);
        TabSpec tabSpecBerry = tabHost
          .newTabSpec("Berry")
          .setIndicator("", ressources.getDrawable(R.drawable.icon_blackberry_config))
          .setContent(intentBerry);

        // add all tabs 
        tabHost.addTab(tabSpecAndroid);
        tabHost.addTab(tabSpecApple);
        tabHost.addTab(tabSpecWindows);
        tabHost.addTab(tabSpecBerry);

        //set Windows tab as default (zero based)
        tabHost.setCurrentTab(2);
    }

}


}

here are 4 tabs you can use as many as you want.
Register in android manifest.
Make sure your tabhost in layout file has the id same as in your code.
