I wrote a Tabhost below:
public class AppTabhost extends TabActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
/**find tab host**/
TabHost tabHost = getTabHost();
/**add tabs**/
//tab 1
tabHost.addTab(tabHost
.newTabSpec("tab1")
.setIndicator("tab1")
.setContent(new Intent(AppTabhost.this, anotherActivity.class)));
//tab 2
tabHost.addTab(tabHost
.newTabSpec("tab2")
.setIndicator("tab2")
.setContent(new Intent(AppTabhost.this, theotherActivity.class)));
}
I want to put it on the bottom of every Activity in my App
How can I do?
You could slap an Intent in there like
Intent I= new Intent(this, Apptabhost.class);
startIntent(I);
But if you want the tabhost to be physically at the bottom of the screen, I would suggest you define a class that will extend tabhost and not tabhost activity. Since a view hierarchy contains views and not activities.
If you want to put it in bottom the you can write this code
android:layout_alignParentBottom="true"
on your tabHost activity xml file

I have not used the activityGroup in my project. Now I'm not is a position to implement the whole project using Activity group.
is it nesssory that I must implement the activityGroup class in my project to do so?
If yes then please give links for the basic tutorial of activityGroup implementation.
Here is my MainActvity.java which loads 4 other actvities in 4 tabs.
public class MainActivity extends TabActivity {
TabHost tabHost;
Context context = MainActivity.this;
Button btnGo;
TabSpec spec;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnGo = (Button) findViewById(R.id.btn_GO);
tabHost = getTabHost();
// Android tab
Intent intentHome = new Intent();
intentHome.setClass(this, Home.class);
TabSpec tabSpecHome = tabHost
.newTabSpec("Home")
.setIndicator("Home",
getResources().getDrawable(R.drawable.home))
.setContent(intentHome);
tabHost.addTab(tabSpecHome);
Intent intentNowReading = new Intent().setClass(this, NowReading.class);
TabSpec tabSpecNowReading = tabHost
.newTabSpec("Now Reading")
.setIndicator("Now Reading",
getResources().getDrawable(R.drawable.now_reading))
.setContent(intentNowReading);
tabHost.addTab(tabSpecNowReading);
Intent intentFavourite = new Intent().setClass(this, Favorites.class);
TabSpec tabSpecFavourite = tabHost
.newTabSpec("Favourite")
.setIndicator("Favorites",
getResources().getDrawable(R.drawable.favorites))
.setContent(intentFavourite);
tabHost.addTab(tabSpecFavourite);
Intent intentProfile = new Intent().setClass(this, Profile.class);
TabSpec tabSpecProfile = tabHost
.newTabSpec("Profile")
.setIndicator("Profile",
getResources().getDrawable(R.drawable.profile))
.setContent(intentProfile);
tabHost.addTab(tabSpecProfile);
tabHost.setCurrentTabByTag("Home");
...}
now I want to start the new activity in the Home tab area on the click event of Go button.(See the picture).
please note that I do not want to impelement the ActivityGroup class, How can I do that without this.
New Actvity must load in the HomeTab's area, not on the full screen.
ActvityGroup is a bad idea, this is old, deprecated API, don't use it.
You have to use Fragments API, just create a Fragment and add it to layout using FragmentTransaction, thats all what you need.
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:

I set the TabHost through the code without using the Layout XML. How do I control Tab appearing at the bottom instead on top. normally its controlled through XML by android:layout_alignParentBottom="true".
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
//setContentView(R.layout.main);
TabHost host=getTabHost();
host.addTab(host.newTabSpec("Offers")
.setIndicator("Offers", getResources().getDrawable(R.drawable.icon_light))
.setContent(new Intent(this, Offer_Popup.class)));
host.addTab(host.newTabSpec("Account")
.setIndicator("Account", getResources().getDrawable(R.drawable.icon_wrench))
.setContent(new Intent(this, Offer_Popup.class)));
host.addTab(host.newTabSpec("Settings")
.setIndicator("Settings", getResources().getDrawable(R.drawable.icon_user))
.setContent(new Intent(this, Offer_Popup.class)));
host.addTab(host.newTabSpec("Awards")
.setIndicator("Awards", getResources().getDrawable(R.drawable.icon_list))
.setContent(new Intent(this, List_Items.class)));
}
}
I guess you are using relative layout (since you are using android:layout_alignParentBottom="true").
Then I belive you need to create RelativeLayout layout parameters and apply them to your TabWidget, something like this:
RelativeLayout.LayoutParams rllp = new RelativeLayout.LayoutParams(..., ...);
rllp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
tw.setLayoutParams(rllp); //where tw is your TabWidget
It's programmatical equivalent of using android:layout_alignParentBottom="true"
I want to design a page in which i just want to show only one tab. But when i add only one tab, it takes the full width available but i want that tab only takes small space and remaining space is left empty. No other tabs i want to add. Only one tab is displayed all time. Code is following
public class TabViewActivity extends TabActivity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TabHost tabHost = getTabHost(); // The activity TabHost
TabHost.TabSpec spec; // Resusable TabSpec for each tab
Intent intent; // Reusable Intent for each tab
// Create an Intent to launch an Activity for the tab (to be reused)
intent = new Intent().setClass(this, FirstTab.class);
// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("firstTab").setIndicator("First Tab")
.setContent(intent);
tabHost.addTab(spec);
tabHost.setCurrentTab(1);
Use tabHost.getTabWidget().getChildAt(0).getLayoutParams().width =(int) 30; also set the layout_width="wrap_content"
In your xml hide the tab widget by setting the visibility to gone. and instead use a button. And in the button handler you can use code like
public void tabHandler(View target){
artistButton.setSelected(false);
albumButton.setSelected(false);
if(target.getId() == R.id.artist_id){
tabHost.setCurrentTab(0);
artistButton.setSelected(true);
} else if(target.getId() == R.id.album_id){
tabHost.setCurrentTab(1);
albumButton.setSelected(true);
}
}
I need little bit help related to android tabhost. I have 3 tabs and 3 activities. MainTab activity is "extends from TabActivity" and other 2 activities are "extends from Activity".
In MainTab activity there are two buttons Radio and CheckBox, when user click radio button then i want to display radio button view in tab2. when user click check box i want to display checkbox view. Can some gives me an idea how I can achieve this?? Below is my code.
public class MainTabHost extends TabActivity implements OnTabChangeListener{
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.homeui);
TabHost tabHost = getTabHost();
tabHost.setOnTabChangedListener(this);
TabHost.TabSpec spec;
Intent intent;
intent = new Intent().setClass(this, Main.class);
spec = tabHost.newTabSpec("Main Tab").
setIndicator("Main Tab")
.setContent(intent);
spec.setIndicator("", this.getResources().getDrawable(R.drawable.maintabicon) );
tabHost.addTab(spec);
intent = new Intent().setClass(this, TabA.class);
spec = tabHost.newTabSpec("Tab A").
setIndicator("Tab A")
.setContent(intent);
spec.setIndicator("", this.getResources().getDrawable(R.drawable.tabaicon) );
tabHost.addTab(spec);
tabHost.setCurrentTab(0);
}
#Override
public void onTabChanged(String tabId) {
}
}
You can use SharedPreference for this. So that when you choose radio button you can change your shared value to radio and when you use Check box change value to check box and use the view in your second tab according to the shared value.
