SelectItem.java (Custom Tab Host)

public class SelectItem extends TabActivity {   

private TabHost mTabHost;

private void setupTabHost() {
    mTabHost = (TabHost) findViewById(android.R.id.tabhost);
    mTabHost.setup();
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.select_item);   
    context=this;       

    setupTabHost();
    mTabHost.getTabWidget().setDividerDrawable(null);
    setupTab(new TextView(this), getString(R.string.Positions),Constants.ActivityName.Positions.toString());
    setupTab(new TextView(this), getString(R.string.Sever),Constants.ActivityName.Sever.toString());

}

private void setupTab(final View view, final String tag,final String activityName) {
    View tabview = createTabView(mTabHost.getContext(), tag);

    TabSpec setContent = mTabHost.newTabSpec(tag).setIndicator(tabview).setContent(new TabContentFactory() {
        public View createTabContent(String tag) {return view;}
    });
    Intent  intent =null;
    if(activityName.compareToIgnoreCase(Constants.ActivityName.Positions.toString())==0)        
        intent = new Intent().setClass(this, Items.class);  
    else if(activityName.compareToIgnoreCase(Constants.ActivityName.Sever.toString())==0)
        intent = new Intent().setClass(this, Sever.class);      
    intent.putExtra(Constants.PROJECT_ID, projectId);
    setContent.setContent(intent);
    mTabHost.addTab(setContent);

}

private static View createTabView(final Context context, final String text) {
    View view = LayoutInflater.from(context).inflate(R.layout.tabs_bg, null);
    TextView tv = (TextView) view.findViewById(R.id.tabsText);
    tv.setText(text);
    return view;
}

}

On Server activity i want to get view of LinearLayout of select_item.xml file. But i am able to get details of tab host in Sever activity.

Please suggest me usable link or sample code.
