i need to get the Activitys initialize , before anyone click on them . That is cause i have a video in one of them , and i need to have that Activity created to play the video from another tab (or activitys) .
I have this code to initialize the tab content but not the activitys into them :
//Init Tabs
Resources res = this.getResources();
TabHost tabHost = getTabHost();
tabHost.getTabWidget().setDividerDrawable(R.drawable.tab_divider);
setupTab(tabHost,MyInitActivity.class,res.getDrawable(R.drawable.ic_tab_icon),res.getString(R.string.tab_init));
setupTab(tabHost,MusicGroupActivity.class,res.getDrawable(R.drawable.ic_tab_icon),res.getString(R.string.tab_playList));
setupTab(tabHost,SearchActivity.class,res.getDrawable(R.drawable.ic_tab_icon),res.getString(R.string.tab_search));
setupTab(tabHost,VideoActivity.class,res.getDrawable(R.drawable.ic_tab_icon),res.getString(R.string.tab_video));
I have seen code like this to try it :
tabHost.setCurrentTab(number);
but that seems to not run when you change immediately cause when i do
Context context = getTabHost().getChildAt(3).getContext();
it throws to me a null exception.
Anyone knows how to do this?
ADDED
private void setupTab( TabHost mTabHost,Class<? extends Activity> activityclass,Drawable image, String tag)
{
View tabview = createTabView(mTabHost.getContext(),image,tag);
TabSpec setContent = mTabHost.newTabSpec(tag).setIndicator(tabview).setContent(new Intent(this, activityclass));
mTabHost.addTab(setContent);
}
Thanks for all
I do the following in the onCreate() (say i have 4 tabs)
tabHost.setCurrentTab(0);
tabHost.setCurrentTab(1);
tabHost.setCurrentTab(2);
tabHost.setCurrentTab(3);
tabHost.setCurrentTab(Tab_I_Want);

I have a tabActivity where I am adding tabs on runtime. So I think this is the usual code to do that:
_tabSpec = TabHost.newTabSpec("More");
_tabSpec.setIndicator("", Resources.GetDrawable(Resources.Drawable.myIcon).SetContent(intent);
TabHost.AddTab(_tabSpec);
Now the thing is, I have defined an options menu and I want to pop that up when the user clicks on the 'More' tab. I don't know how to do that. I tried not setting a content on that tab and simply use the OpenOptionsMenu() to pop it, but it doesn't seem to work.
Any clue how to achieve that?
P.S.: This is a C# code written in Xamarin. It might not look like the native java-android code, but its almost the same.
Alright, here's an answer to what I was trying to do.
Motive: Add a 'More' tab to the existing TabActivity. When user clicks it, open some kind of a PopUpWindow or ContextMenu, etc.
Steps to do that:
1) Create a tabSpec and add that tab to the TabHost as shown in the question.
2) Now you need to take in this last added tab as a View type variable. Do this by..
View v = TabWidget.GetChildAt(index)
Remember index of tabs starts from 0
3) Now on the onCreate() method of your main activity (one that holds the TabActivity) add an onTouchListener() (I use C#, so I added v.Click+=myFunction()) and write your code of the PopupWindow or ContextMenu or whatever you want to do there.
private String lastTab = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final TabHost tabHost = getTabHost();
TabHost.TabSpec tabSpec;
tabSpec = tabHost.newTabSpec("tab1");
tabSpec.setIndicator("Tab 1");
tabSpec.setContent(new Intent(this, OneActivity.class));
tabHost.addTab(tabSpec);
tabSpec = tabHost.newTabSpec("tab2");
tabSpec.setIndicator("Tab 2");
tabSpec.setContent(new Intent(this, TwoActivity.class));
tabHost.addTab(tabSpec);
tabSpec = tabHost.newTabSpec("more");
tabSpec.setIndicator("More");
tabSpec.setContent(new Intent(this, OneActivity.class));
tabHost.addTab(tabSpec);
tabHost.setOnTabChangedListener(new OnTabChangeListener() {
#Override
public void onTabChanged(String tabId) {
if (tabId.equalsIgnoreCase("more")){
openOptionsMenu();
tabHost.setCurrentTabByTag(lastTab);
}
else lastTab = tabId;
}
});
}
I am using a Tab host two show two list on two tabs but I want that when click on second tab then it should reload the first tab data.How is it possible?
My code is like this
TabHost tabs = (TabHost)findViewById(R.id.tabhost_spices);
tabs.setup();`enter code here`
TabHost.TabSpec tab1 = tabs.newTabSpec("tab1");
tab1.setContent(R.id.list_spices_fav);
tab1.setIndicator("Favorite",getContext().getResources().getDrawable(R.drawable.tab_fav_icon));
tabs.addTab(tab1);
// create tab 2
TabHost.TabSpec tab2 = tabs.newTabSpec("tab2");
tab2.setContent(R.id.list_spices_categories);
tab2.setIndicator("View List",getContext().getResources().getDrawable(R.drawable.tab_cat_icon));
tabs.addTab(tab2);
Here is a tutorial,This Help me- link
Extends your activity with TabActivity
TabHost tabHost;
tabHost = getTabHost();
Resources res = getResources();
TabSpec tabspec1 = tabHost.newTabSpec("").setIndicator("Tab1",res.getDrawable(R.drawable.ic_launcher)).setContent(new Intent(this, FirstActivity.class));
tabHost.addTab(tabspec1);
TabSpec tabspec2 = tabHost.newTabSpec("").setIndicator("Tab2",res.getDrawable(R.drawable.ic_launcher)).setContent(new Intent(this, SecondActivity.class));
tabHost.addTab(tabspec2);
For refreshing the data of new Tab you have to keep the code for refereshing the data inside onResume() of that Activity because when TabActivity is created its all the tabs make a call to the respective Activities calling its onCreate()'. So, when you click the Tab once its loaded itsonResume()method is called and notonCreate()`.
Hi I am creating an application. In this I need to display a TabBar in all Activities. I set the TabBar bottom using 4 tabs; home, contact, about and call us.
Inside home tab I have some buttons. When I click inside home any button that time I need to move some other Activity. Using intent I moved to another Activity but here the TabBar was not displayed. However, I need to display the same TabBar in all Activities. If any one knows how to do this, please suggest a solution to me.
DefenceLaywer.java:
public class DefenceLaywer extends TabActivity {
TabHost tabhost;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tabhost = (TabHost)findViewById(android.R.id.tabhost);
TabSpec firstTabSpec = tabhost.newTabSpec("Home");
TabSpec secondTabSpec = tabhost.newTabSpec("Claimonline");
TabSpec thirdTabSpec = tabhost.newTabSpec("CallUs");
TabSpec fourthTabSpec = tabhost.newTabSpec("AboutUs");
// TabSpec thirdTabSpec = tabhost.newTabSpec("Interactive");
firstTabSpec.setIndicator("Home", getResources().getDrawable(R.drawable.home));
secondTabSpec.setIndicator("ContactUs", getResources().getDrawable(R.drawable.contactus));
thirdTabSpec.setIndicator("CallUs", getResources().getDrawable(R.drawable.callus));
fourthTabSpec.setIndicator("AboutUs", getResources().getDrawable(R.drawable.aboutus));
firstTabSpec.setContent(new Intent(this,HomeTab.class));
secondTabSpec.setContent(new Intent(this,ContactUs.class));
thirdTabSpec.setContent(new Intent(this,CallUs.class));
fourthTabSpec.setContent(new Intent(this,AboutUs.class));
tabhost.addTab(firstTabSpec);
tabhost.addTab(secondTabSpec);
tabhost.addTab(thirdTabSpec);
tabhost.addTab(fourthTabSpec);
}

use fragments in activity and set that activity on tabspecs.
To learn FrAgment use following lin:
http://developer.android.com/guide/topics/fundamentals/fragments.html
and for how to use fragments to implement tab, follow followig tutorial:
http://android.codeandmagic.org/2011/07/android-tabs-with-fragments/
I made custom tabs using this tutorial: http://joshclemm.com/blog/?p=136
I have them completely customized and looking nice, but now I don't know how to add content to the tabs. I don't even know where to start with the way this code is written, any help? Thanks.
This is the code that I think sets the content:
private void setupTab(final View view, final String tag) {
View tabview = createTabView(mTabHost.getContext(), tag);
TabSpec setContent = mTabHost.newTabSpec(tag).setIndicator(tabview).setContent(new TabContentFactory() {
public View createTabContent(String tag) {return view;}
});
mTabHost.addTab(setContent);
}
I don't know what this is doing with "TabContentFactory"
I too followed the same blog and was facing problem, while adding the Intent's. So, finally I fixed it myself. What I did is,
1.) public class CustomTabActivity extends Activity here I changed it to extend TabActivity
2.) Just add the content using Intent
Intent intent = new Intent().setClass(this, Hello.class);
TabSpec setContent = mTabHost.newTabSpec(tag).setIndicator(tabview).setContent(intent);
That's it and it worked. Hope this works for you too.
Try following the tutorial given on the android website. Combined with the tutorial you used, it should give you completely what you want.
Specifically, to add content to to each tab you add and activity to each tab like so:
spec = tabHost.newTabSpec("artists").setIndicator("Artists",
res.getDrawable(R.drawable.ic_tab_artists))
.setContent(intent);
tabHost.addTab(spec);
Look at this:
private void addActivityTab(int labelResId, int iconResId, Intent intent) {
String tabLabel = getString(labelResId);
View indicator = View.inflate(this, R.layout.simple_tab_spec, null);
ImageView icon = (ImageView) indicator.findViewById(R.id.simple_tab_spec_icon);
icon.setImageResource(iconResId);
TabSpec tabSpec = tabHost.newTabSpec(tabLabel).setIndicator(indicator).setContent(intent);
tabHost.addTab(tabSpec); }
The first argument is the title of your tab item, the second argument is the background image of your tab item.
You should create an intent object to set the parameters and the target activity.
I want to have a TabHost which consists of two tabs: one created from View (R.id.something) and the second one from Activity.
So I do that like this:
mTab = (TabHost) findViewById(R.id.tabhost);
mTab.setup();
TabHost.TabSpec spec = mTab.newTabSpec("All");
spec.setContent(R.id.all_tab); // Created from View
spec.setIndicator("All", getResources().getDrawable(R.drawable.emo_im_cool));
mTab.addTab(spec);
Intent intent = new Intent().setClass(this, TasksDone.class);
spec = mTab.newTabSpec("Done");
spec.setIndicator("Done", getResources().getDrawable(R.drawable.emo_im_happy));
spec.setContent(intent); // Created from Intent
mTab.addTab(spec);
After that the content on the first tab isn't visible, but it's there because I see reaction on my clicks.
But it appears if I set the setContent of a second tab as a View instead of intent.
Do you guys know why the content on the first page is invisible?
Mh, have you tried spec.setContent(R.layout.all)? I assume there should be a layout id, not the id of a view-object.
The root of the problem was a mistake in xml.
