How to add tabHost to Subactivity in Android?
I want to add TabHost to SubActivity.
eg. I have an Activity called MainActivity that represents a TabHost. I have five tabs in my tab. in each Host tab I open Activity A, B, C, D, E.
Now when I want move from Activity A to some different activity e.g Z.
then I am not able to add TabHost into Z. It totally disappeared from Activity Z.
So Is there any solution for this issue ? Please help me.
Here is the source for MainActivity:
public class MainActivity extends TabActivity {
public static final String TAG_1 = "tab1";
public static final String TAG_2 = "tab2";
public static final String TAG_3 = "tab3";
public static final String TAG_4 = "tab4";
public static final String TAG_5 = "tab5";
public TabHost mTabHost;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mTabHost = getTabHost();
setTabs();
}
public void setTabs() {
mTabHost = (TabHost) findViewById(android.R.id.tabhost);
mTabHost.setup();
addTab("Home", TAG_1, createTabDrawable(R.drawable.home), FeedBack.class);
addTab("Near Me", TAG_2, createTabDrawable(R.drawable.search), NearMe.class);
addTab("Share", TAG_3, createTabDrawable(R.drawable.star),Home.class);
addTab("FeedBack", TAG_4, createTabDrawable(R.drawable.settings),FeedBack.class);
addTab("Options", TAG_5, createTabDrawable(R.drawable.settings),NearMe.class);
}
public Drawable createTabDrawable(int resId) {
Resources res = getResources();
StateListDrawable states = new StateListDrawable();
final Options options = new Options();
options.inPreferredConfig = Config.ARGB_8888;
Bitmap icon = BitmapFactory.decodeResource(res, resId, options);
Bitmap unselected = TabBitmap.createUnselectedBitmap(res, icon);
Bitmap selected = TabBitmap.createSelectedBitmap(res, icon);
icon.recycle();
states.addState(new int[] { android.R.attr.state_selected }, new BitmapDrawable(res, selected));
states.addState(new int[] { android.R.attr.state_enabled }, new BitmapDrawable(res, unselected));
return states;
}
public View createTabIndicator(String label, Drawable drawable) {
View tabIndicator = LayoutInflater.from(this).inflate(R.layout.tab_indicator, mTabHost.getTabWidget(), false);
TextView txtTitle = (TextView) tabIndicator.findViewById(R.id.text_view_tab_title);
txtTitle.setText(label);
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) txtTitle.getLayoutParams();
txtTitle.setLayoutParams(params);
ImageView imgIcon = (ImageView) tabIndicator.findViewById(R.id.image_view_tab_icon);
imgIcon.setImageDrawable(drawable);
return tabIndicator;
}
public void addTab(String label, String tag, Drawable drawable, Class<?> c) {
Intent intent = new Intent(this, c);
TabHost.TabSpec spec = mTabHost.newTabSpec(tag);
spec.setIndicator(createTabIndicator(label, drawable));
spec.setContent(intent);
mTabHost.addTab(spec);
}
}

Try it, it works for me .. in your main activity onCreate ()
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.home);
etSearch = (EditText)findViewById(R.id.etSearch);
TabHost tabhost = getTabHost();
TabSpec first = tabhost.newTabSpec("All Submissions");
first.setIndicator("All Submissions" ,getResources().getDrawable(R.drawable.submission));
Intent intent1 = new Intent(this, AllSubmissionActivity.class);
first.setContent(intent1);
//tabhost.addTab(first);
TabSpec second = tabhost.newTabSpec("All Districts");
second.setIndicator("All Districts" ,getResources().getDrawable(R.drawable.district));
Intent intent2 = new Intent(this, AllDistrictActivity.class);
second.setContent(intent2);
//tabhost.addTab(second);
TabSpec third = tabhost.newTabSpec("All Schools");
third.setIndicator("All Schools" ,getResources().getDrawable(R.drawable.school));
Intent intent3 = new Intent(this, AllSchoolActivity.class);
third.setContent(intent3);
//tabhost.addTab(third);
if(DataContainer.UserCredentials.uname.equals("sadmin"))
{
tabhost.addTab(first);
tabhost.addTab(second);
tabhost.addTab(third);
}
else if(DataContainer.UserCredentials.uname.equals("b"))
{
tabhost.addTab(second);
tabhost.addTab(third);
}
else
{
tabhost.addTab(third);
}
tabhost.setCurrentTab(0);
}
you need to follow the same procedure to add tabs to your activity as basically ...
in ancillary activity
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.allsubmission);
initializeTabHost();
}
and this will initialize the TabHoast () method.
public void initializeTabHost(){
tabhost = getTabHost();
TabSpec first = tabhost.newTabSpec("Details");
first.setIndicator("Details" ,null);
Intent intent1 = new Intent(this, DetailsCrimeOnLink.class);
intent1.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
first.setContent(intent1);
tabhost.addTab(first);
TabSpec second = tabhost.newTabSpec("Maps");
second.setIndicator("Maps" ,null);
Intent intent2 = new Intent(this, MapsCrimeOnLink.class);
second.setContent(intent2);
tabhost.addTab(second);
TabSpec third = tabhost.newTabSpec("Notes");
third.setIndicator("Notes" ,null);
Intent intent3 = new Intent(this, NotesCrimeOnLink.class);
third.setContent(intent3);
tabhost.addTab(third);
TabSpec fourth = tabhost.newTabSpec("History");
fourth.setIndicator("History" ,null);
Intent intent4 = new Intent(this, HistoryCrimOnLink.class);
fourth.setContent(intent4);
tabhost.addTab(fourth);
tabhost.setCurrentTab(0);
}
