How to show Badge in TabHost

This is my MainActivity.java:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);
Resources ressources = getResources();
TabHost tabHost = getTabHost();
registerReceiver(myBroadcastReceiver1, new IntentFilter(
MYBROADCAST_INTENTFILTER));
Intent intentFriends = new Intent().setClass(this,
TabFriendsActivity.class).addFlags(
Intent.FLAG_ACTIVITY_CLEAR_TOP);
TabSpec tabFriends = tabHost
.newTabSpec("Friends")
.setIndicator("",
ressources.getDrawable(R.drawable.btn_tab_friends))
.setContent(intentFriends);
// Talks tab
Intent intentTalks = new Intent()
.setClass(this, TabTalksActivity.class).addFlags(
Intent.FLAG_ACTIVITY_CLEAR_TOP);
TabSpec tabTalks = tabHost
.newTabSpec("Talks")
.setIndicator("",
ressources.getDrawable(R.drawable.btn_tab_talk))
.setContent(intentTalks);
// Add friends tab
Intent intentAddFriends = new Intent().setClass(this,
TabAddFriendsActivity.class).addFlags(
Intent.FLAG_ACTIVITY_CLEAR_TOP);
TabSpec tabAddFriends = tabHost
.newTabSpec("Add friends")
.setIndicator("",
ressources.getDrawable(R.drawable.btn_tab_addfriend))
.setContent(intentAddFriends);
// Other tab
Intent intentOther = new Intent()
.setClass(this, TabOtherActivity.class).addFlags(
Intent.FLAG_ACTIVITY_CLEAR_TOP);
TabSpec tabSpecOther = tabHost
.newTabSpec("Other")
.setIndicator("",
ressources.getDrawable(R.drawable.btn_tab_other))
.setContent(intentOther);
// add all tabs
tabHost.addTab(tabFriends);
tabHost.addTab(tabTalks);
tabHost.addTab(tabAddFriends);
tabHost.addTab(tabSpecOther);
// set Windows tab as default (zero based)
tabHost.setCurrentTab(0);
TabWidget tabs = (TabWidget) findViewById(android.R.id.tabs);
badge = new BadgeView(this, tabs, 1);
badge.setText("new");
}
I want to show text "new" in tabTalks when I got message from GCM by BroadcastReceiver. I try to debug and got information of "intentChatting" that means BroadcastReceiver is working, but text "new" not show in tabTalks icon.
private BroadcastReceiver myBroadcastReceiver1 = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
String intentChatting = intent.getExtras().get("Intent").toString();
if (intentChatting != null) {
pushBadge(intentChatting);
}
}
};
private void pushBadge(String intentChating) {
badge.show();
}
And this is my main_activity.xml:
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#f2f2f2">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="462dp"
android:layout_weight="0.07">
</FrameLayout>
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#000" />
</LinearLayout>
</TabHost>
So, what wrong with my code. I want to show badge in tabhost when receiver message from GCMby BroadcastReceiver. But it's not work!
Any help much appreciated! Thanks.

how to set tabhost on top of the content

Hy everyone
i am using TabHost to create TabBar in android....
public class TabBarActivity extends TabActivity implements OnTabChangeListener
{
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tab);
TabHost tabHost = getTabHost();
TabHost.TabSpec spec;
Intent intent;
intent = new Intent().setClass(this, CustomizedListView.class);
spec = tabHost.newTabSpec("Clubs").setIndicator("Clubs", getResources().getDrawable(R.drawable.clubs_icon))
.setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, Events.class);
spec = tabHost.newTabSpec("Events").setIndicator("Events", getResources().getDrawable(R.drawable.events_icon))
.setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, Maps.class);
spec = tabHost.newTabSpec("Maps").setIndicator("Maps", getResources().getDrawable(R.drawable.maps_icon))
.setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, Settings.class);
spec = tabHost.newTabSpec("Settings").setIndicator("Settings", getResources().getDrawable(R.drawable.settings_icon))
.setContent(intent);
tabHost.addTab(spec);
getTabHost().setOnTabChangedListener(this);
}
#Override
public void onTabChanged(String tabId)
{
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "Inside the new tab ", Toast.LENGTH_SHORT).show();
//getTabHost().setVisibility(View.VISIBLE);
}
}
**tab.xml**
<?xml version="1.0" encoding="utf-8"?>
<TabHost
android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<RelativeLayout
android:id="#+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TabWidget
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:id="#android:id/tabs">
</TabWidget>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#android:id/tabcontent">
</FrameLayout>
</RelativeLayout>
</TabHost>
but the problem is that whenever the contents of the tab grow e.g displaying dynamic content in listview against a tab then the TabHost becomes INVISIBLE..
any help in this regard will be highly appreciated....

Insted of using TabActivity use normal Activity. and then create TabHost with the tabspec based on your requirement. and add that tabHost as your first component in the screen/Activity.

Tab OnClickListener in another activity

My Tools.java :
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.tabtools);
Resources res = getResources();
TabHost tabHost = getTabHost();
TabHost.TabSpec spec;
Intent intent;
// TabDados
intent = new Intent().setClass(this, ToolDadosTubuCirc.class);
spec = tabHost.newTabSpec("dados")
.setIndicator("Dados", res.getDrawable(R.drawable.icondados))
.setContent(intent);
tabHost.addTab(spec);
// TabLegenda
intent = new Intent().setClass(this, ToolLegendaTubuCirc.class);
spec = tabHost
.newTabSpec("legenda")
.setIndicator("Legenda",
res.getDrawable(R.drawable.iconlegenda))
.setContent(intent);
tabHost.addTab(spec);
// TabCalcular
intent = new Intent().setClass(this, ToolCalcularTubuCirc.class);
spec = tabHost
.newTabSpec("calcular")
.setIndicator("Calcular",
res.getDrawable(R.drawable.iconcalcular))
.setContent(intent);
tabHost.addTab(spec);
// TabCorrente
tabHost.setCurrentTab(0);}}
My tabtools.xml
<TabHost
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#+layout/rowLog"
android:layout_below="#+layout/rowLine" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:padding="5dp" >
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="5dp" />
</LinearLayout>
The first tab is called the class "ToolDadosTubuCirc.java" and this activity has the following code:
package br.com.mobile4you.engtools;
import android.app.Activity;
import android.os.Bundle;
public class ToolCalcularTubuCirc extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.toolcalculartubucirc);
}
}
**How to create an event within the file onClickListener "ToolDadosTubuCirc.java"?
I need to create a function that when people click on the tab "calcular" do some test data it should fill in the tab "dados".
I have 3 tabs: tab1 = data; tab2 = legend; tab3 = calculate.
The corrent tab is the "data". I need to check when the User click on the tab "calculate" to all fields of the tab "Data" was completed. I do not know create the onclickListener event for TabDados in other activity(class). I dont know the id of the tabhost and TabWidget.
How to create this event? Thank you!**
If the id of my tabhost is standard android and my id is also TabWidget. I am not able to do this event. Help me.

Question is unclear
"I need to create a function that when people click on the tab". Assume mTabWidget is your TabWidget control, and nTabOffset = 0, i.e. the offset of your dados tab:
mTabWidget.getChildAt(nTabOffset).setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View v)
{
// TODO:
}
});
TabHost will instantiate your activity and call onCreate(). You would initialize your activities views there, though if you want a tab click event to re-initiate some data update, you could do this via the onClick() method above, perhaps sending a broadcast intent that is registered in your activity.

load two .swf flies in a Tab Layout

I use a Tab Layout display two .swf files and a imageView in three tabs. However, when I wanted to change to imageView from a swf tab. The swf still exits.
//TabActivity
public class TabSwfActivity extends TabActivity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Resources res = getResources(); // Resource object to get Drawables
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, OperatorActivity.class);
// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("artists").setIndicator("artists")
.setContent(intent);
tabHost.addTab(spec);
// Do the same for the other tabs
intent = new Intent().setClass(this, LearningActivity.class);
spec = tabHost.newTabSpec("albums").setIndicator("albums")
.setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, QuestionActivity.class);

TabLayout Android, customize background color

in android tutorial there isn't a way for customize tab background. my app is official-tutorial based..can anyone help me with a tutorial or code for backgroundcolor white?
this is my code:
LauncherActivity.java
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.launcher);
Resources res = getResources();
TabHost tabHost = getTabHost();
TabHost.TabSpec spec;
Intent intent;
intent = new Intent().setClass(this, MyActivity.class);
spec = tabHost.newTabSpec("myactivity").setIndicator("Activity")
.setContent(intent);
tabHost.addTab(spec);
// Do the same for the other tabs
intent = new Intent().setClass(this, search.class);
spec = tabHost.newTabSpec("search").setIndicator("Search"
)
.setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, MyActivity3.class);
spec = tabHost.newTabSpec("songs").setIndicator("Songs"
)
.setContent(intent);
tabHost.addTab(spec);
tabHost.setCurrentTab(0);
}
Launcher.xml
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="[url]http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="5dp">
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="0dp" />
</LinearLayout>
</TabHost>

If you mean to change background color of tabs,then here is the code:
for(int i=0;i<tabhost.getTabWidget().getChildCount();i++)
{
tabhost.getTabWidget().getChildAt(i).setBackgroundColor(Color.WHITE); //unselected tab
}
for selected tab,
tabhost.getTabWidget().getChildAt(tabhost.getCurrentTab()).setBackgroundColor(Color.GRAY); // selected tab
You can put above lines into a method (say setTabColors()) and call it:
tabHost.setOnTabChangedListener(new OnTabChangeListener() {
#Override
public void onTabChanged(String arg0) {
setTabColors(tabHost);
}
});
