i've got this Tabhost:
TabHost tabHost = getTabHost();
TabHost.TabSpec spec;
Intent intent;
/** Initialization Tab1 */
intent = new Intent(this, Tab1.Class);
spec = tabHost.newTabSpec("Tab1").setIndicator("Tab1").setContent(intent);
tabHost.addTab(spec);
/** Initialization Tab2 */
intent = new Intent(this, Abstand.class);
spec = tabHost.newTabSpec("Tab2").setIndicator("Tab2").setContent(intent);
tabHost.addTab(spec);
tabHost.setCurrentTab(0);
The content of Tab2 has some buttons, when one of these is clicked, it starts a SubActivity with:
final Intent i = new Intent(this, SubActivity.class);
final Bundle b = new Bundle();
this.mButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
b.putString("key", "value");
i.putExtras(b);
startActivityForResult(i, REQUEST_CODE);
}
});
Within the SubActivity, the Tabhost isnt available anymore... so how can the Code be changed, showing the Tabhost in a SubActivity?

I am creating a android app.
which have a welcome screen where four button (a,b,c,d) have.
when click on the any button(a,b,c,d) its goes to the second activity.
next activity have (tabhost)four tabs(a,b,c,d).
how can it work--
when i click on "a" button in welcome screen it goes to "a tab" of second activity,and another tabs are also working.
when i click on "b" button in welcome screen it goes to "b tab" of second activity,and another tabs are also working.
when i click on "c" button in welcome screen it goes to "c tab" of second activity,and another tabs are also working.
when i click on "d" button in welcome screen it goes to "d tab" of second activity,and another tabs are also working.
public class Dashboard extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.dashboard);
}
public void helpB(View v) {
Button clickedButton = (Button) v;
switch (clickedButton.getId()) {
case R.id.points:
Intent i = new Intent(getApplicationContext(),AndroidActivity.class);
startActivity(i);
break;
case R.id.Search:
Intent i1 = new Intent(getApplicationContext(),AppleActivity.class);
startActivity(i1);
break;
case R.id.AboutUs:

startActivity(i2);
break;
case R.id.ContactUs:
Intent i3 = new Intent(getApplicationContext(),WindowsActivity.class);
startActivity(i3);
break;
}
}
}
and second Activity code -->
public class MainActivity extends TabActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Resources ressources = getResources();
TabHost tabHost = getTabHost();
// Android tab
Intent intentAndroid = new Intent().setClass(this,
AndroidActivity.class);
TabSpec tabSpecAndroid = tabHost
.newTabSpec("Android")
.setIndicator("Points",
ressources.getDrawable(R.drawable.icon_android_config))
.setContent(intentAndroid);
// Apple tab
Intent intentApple = new Intent().setClass(this, AppleActivity.class);
TabSpec tabSpecApple = tabHost
.newTabSpec("Apple")
.setIndicator("Search",
ressources.getDrawable(R.drawable.icon_apple_config))
.setContent(intentApple);
// Windows tab
Intent intentWindows = new Intent().setClass(this,
WindowsActivity.class);
TabSpec tabSpecWindows = tabHost
.newTabSpec("Windows")
.setIndicator("About us",
ressources.getDrawable(R.drawable.icon_windows_config))
.setContent(intentWindows);
// Blackberry tab
Intent intentBerry = new Intent().setClass(this,
BlackBerryActivity.class);
TabSpec tabSpecBerry = tabHost
.newTabSpec("Berry")
.setIndicator(
"Contact us",
ressources
.getDrawable(R.drawable.icon_blackberry_config))
.setContent(intentBerry);
// add all tabs
tabHost.addTab(tabSpecAndroid);
tabHost.addTab(tabSpecApple);
tabHost.addTab(tabSpecWindows);
tabHost.addTab(tabSpecBerry);
// set Windows tab as default (zero based)
tabHost.setCurrentTab(0);
}
}
Do you need this?
public void helpB(View v) {
Button clickedButton = (Button) v;
int tab = 0;
Intent i = new Intent(getApplicationContext(),MainActivity.class);
switch (clickedButton.getId()) {
case R.id.points:
tab = 0;
break;
case R.id.Search:
tab = 1;
break;
case R.id.AboutUs:
tab = 2;
break;
case R.id.ContactUs:
tab = 3;
break;
}
i.putExtra("extra.tab", tab);
startActivity(i);
}
And MainActivity:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Resources ressources = getResources();
TabHost tabHost = getTabHost();
// Android tab
Intent intentAndroid = new Intent().setClass(this,
AndroidActivity.class);
TabSpec tabSpecAndroid = tabHost
.newTabSpec("Android")
.setIndicator("Points",
ressources.getDrawable(R.drawable.icon_android_config))
.setContent(intentAndroid);
// Apple tab
Intent intentApple = new Intent().setClass(this, AppleActivity.class);
TabSpec tabSpecApple = tabHost
.newTabSpec("Apple")
.setIndicator("Search",
ressources.getDrawable(R.drawable.icon_apple_config))
.setContent(intentApple);
// Windows tab
Intent intentWindows = new Intent().setClass(this,
WindowsActivity.class);
TabSpec tabSpecWindows = tabHost
.newTabSpec("Windows")
.setIndicator("About us",
ressources.getDrawable(R.drawable.icon_windows_config))
.setContent(intentWindows);
// Blackberry tab
Intent intentBerry = new Intent().setClass(this,
BlackBerryActivity.class);
TabSpec tabSpecBerry = tabHost
.newTabSpec("Berry")
.setIndicator(
"Contact us",
ressources
.getDrawable(R.drawable.icon_blackberry_config))
.setContent(intentBerry);
// add all tabs
tabHost.addTab(tabSpecAndroid);
tabHost.addTab(tabSpecApple);
tabHost.addTab(tabSpecWindows);
tabHost.addTab(tabSpecBerry);
// set Windows tab as default (zero based)
int tab = getIntent().getExtras().getInt("extra.tab");
tabHost.setCurrentTab(tab);
}
I hope you can help, I can't seem to get the current tab to reload if a tab is currently selected and then a user click on it again, could someone point out what I'm doing and perhaps modify my code to show me what I'm doing wrong as I have viewed a lot of threads on here and via google but now one seems to know the answer, that or I'm just dumb :D thank you :)
public class HelloTabWidget extends TabActivity implements OnClickListener {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Resources res = getResources(); // Resource object to get Drawables
final 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, ArtistsActivity.class);
// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("artists").setIndicator("Artists",
res.getDrawable(R.drawable.ic_tab_artists))
.setContent(intent);
tabHost.addTab(spec);
// Do the same for the other tabs
intent = new Intent().setClass(this, AlbumsActivity.class);
spec = tabHost.newTabSpec("albums").setIndicator("Albums",
res.getDrawable(R.drawable.ic_tab_albums))
.setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, SongsActivity.class);

res.getDrawable(R.drawable.ic_tab_songs))
.setContent(intent);
tabHost.addTab(spec);
tabHost.setCurrentTab(0);
tabHost.setOnTabChangedListener(new OnTabChangeListener() {
public void onTabChanged(String tabId) {
// Log.d(debugTag, "onTabChanged: tab number=" + mTabHost.getCurrentTab());
switch (tabHost.getCurrentTab()) {
case 0:
//do what you want when tab 0 is selected
test();
break;
case 1:
//do what you want when tab 1 is selected
break;
default:
break;
}
}
});
}
public void test (){
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Warning");
alert.setMessage("You are about to self-destruct!");
alert.show();
}
First create one variable in application class like below:
public class GlobalClass extends Application {
public int displayTab = 0;
public int getDisplayTab() {
return displayTab;
}
public void setDisplayTab(int displayTab) {
this.displayTab = displayTab;
}
}
and modify your Activity as below:
public class HelloTabWidget extends TabActivity implements OnClickListener {
GlobalClass globel;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
globel = (GlobalClass) getApplication();
Resources res = getResources(); // Resource object to get Drawables
final 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, ArtistsActivity.class);
// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("artists").setIndicator("Artists",
res.getDrawable(R.drawable.ic_tab_artists))
.setContent(intent);
tabHost.addTab(spec);
// Do the same for the other tabs
intent = new Intent().setClass(this, AlbumsActivity.class);
spec = tabHost.newTabSpec("albums").setIndicator("Albums",
res.getDrawable(R.drawable.ic_tab_albums))
.setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, SongsActivity.class);
spec = tabHost.newTabSpec("songs").setIndicator("Songs",
res.getDrawable(R.drawable.ic_tab_songs))
.setContent(intent);
tabHost.addTab(spec);
tabHost.setCurrentTab(globel.getDisplayTab());
//Here Handling first tab click
getTabWidget().getChildAt(0).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
test();
Log.d("Clickedddddddddddd", "1"
+ getTabHost().getCurrentTabTag());
HelloTabWidget.this.finish();
globel.setDisplayTab(0);
Intent i = new Intent(HelloTabWidget.this, HelloTabWidget.class);
startActivity(i);
}
});
}
public void test (){
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Warning");
alert.setMessage("You are about to self-destruct!");
alert.show();
}
}
i want to make an intent from a tab to another.. how can i do that?
i only now how to make between activity's. and i need to go from a tab to another..
i have this code for the tabs
public class Main extends TabActivity
{
#Override
protected void onCreate(Bundle savedInstanceState)
{
// TODO Auto-generated method stub
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, Contas.class);
Intent a = new Intent(Main.this, Contas.class);
Intent b = new Intent(Main.this, Registros.class);
Intent c = new Intent(Main.this, Relatorios.class);
// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("Contas").setIndicator("Contas",
res.getDrawable(R.drawable.ic_tab_accounts))
.setContent(a.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
tabHost.addTab(spec);
// Do the same for the other tabs
//intent = new Intent().setClass(this, Registros.class);
spec = tabHost.newTabSpec("Registros").setIndicator("Registros",
res.getDrawable(R.drawable.ic_tab_registry))
.setContent(b.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
tabHost.addTab(spec);
//intent = new Intent().setClass(this, Relatorios.class);
spec = tabHost.newTabSpec("Relatorios").setIndicator("Relatorios",
res.getDrawable(R.drawable.ic_tab_reports))
.setContent(c.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
tabHost.addTab(spec);
tabHost.setCurrentTab(0);
}
}
Rather then calling intent you can just set the desired tab selected.
tabHost.setCurrentTab(index)
Rather then calling intent you can just set the desired tab selected.
Use
intent.putExtra("tabIndex", index);
and call the activity. Now in the calling Activity's onCreate() or onResume() use
int index = getIntent().getExtraInt("tabIndex", -1);
if(index != -1)
tabHost.setCurrentTab(index);
I have an application with 3 tab (tab1, tab2, tab3) How can I move to the tab2 if a press a bottom in tab1.
I have this....
Resources res= getResources();
TabHost tabHost= getTabHost();
TabHost.TabSpec spec;
Intent intent;
// initialize a TabSpect for each tab and add it to the TabHost
intent= new Intent().setClass(this, StockMarket.class);
spec= tabHost.newTabSpec("1").setIndicator("Stock Market", res.getDrawable(R.drawable.grafica))
.setContent(intent);
tabHost.addTab(spec);
intent= new Intent().setClass(this, Info.class);
spec= tabHost.newTabSpec("2").setIndicator("Data", res.getDrawable(R.drawable.puzzle)).setContent(intent);
tabHost.addTab(spec);
intent= new Intent().setClass(this, Profile.class);
spec= tabHost.newTabSpec("3").setIndicator("Profile", res.getDrawable(R.drawable.toolbox)).setContent(intent);
tabHost.addTab(spec);
intent= new Intent().setClass(this, Graphic.class);
spec= tabHost.newTabSpec("Graphic").setIndicator("Graphic", res.getDrawable(R.drawable.chart)).setContent(intent);
tabHost.addTab(spec);
thanks
Try this, It was worked for me.
set a method to my main class, which extends TabActivity let's call it "MainActivity"
public TabHost getMyTabHost() {
return tabHost;
}
Then add my tab activity class;
MainActivity ta = (MainActivity) this.getParent();
TabHost t = ta.getMyTabHost();
t.setCurrentTab(0);
you can set tabs with int in setCurrentTab(0).
This might help you -
getTabHost().setOnTabChangedListener(new OnTabChangeListener() {
#Override
public void onTabChanged(String tabId) {
int i = getTabHost().getCurrentTab();
Log.i("TAB NUMBER", + i);
}
});
I have created a tab view. What i want is that when i switch between 2 views of my tab a progress bar is generated. How can i do so.....
Here is my code:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tab);
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
TabWidget tabs = new TabWidget(this);
tabs.setId(android.R.id.tabhost);
// Create an Intent to launch an Activity for the tab (to be reused)
intent = new Intent().setClass(this, ImageExercise.class);
// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("images").setIndicator("Images",
res.getDrawable(R.drawable.imageicon))
.setContent(intent);
tabHost.addTab(spec);
// Do the same for the other tabs
intent = new Intent().setClass(this, AudioPlay.class);
spec = tabHost.newTabSpec("songs").setIndicator("Songs",
res.getDrawable(R.drawable.audioicon))
.setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, VideoActivity.class);
spec = tabHost.newTabSpec("videos").setIndicator("Videos",
res.getDrawable(R.drawable.videoicon))
.setContent(intent);
tabHost.addTab(spec);
tabHost.setCurrentTab(2);
}
}
