I have two tabs in my tabwidget and each tab display a list view.
ay
Initially my first tab is displayed as selected but below list correspond to second tab.
Once i click the tabs, i am getting correct display.
private static final String LIST_TAB_TAG1 = "UpcomingEvents";
private static final String LIST_TAB_TAG2 = "PastEvents";
tabHost.addTab(tabHost.newTabSpec(LIST_TAB_TAG1)
.setIndicator(LIST_TAB_TAG1)
.setContent(new TabContentFactory() {
public View createTabContent(String arg) {
return listView1;
}
}));
tabHost.addTab(tabHost.newTabSpec(LIST_TAB_TAG2)
.setIndicator(LIST_TAB_TAG2)
.setContent(new TabContentFactory() {
public View createTabContent(String arg) {
return listView2;
}
}));
tabHost.setCurrentTab(0);
LIST_TAB_TAG1 is highlighted when this sctivity is launched but the list displayed is listview2. This problem is only when activity starts. Upon clicking tabs its working fine
Can please help me in fixing this. Thanks for your time
I generally use the code given in docs which works fine for me ,try this one .
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
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, UpcomingEvents.class);
// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("UpcomingEvents").setIndicator("UpcomingEvents",getResources().getDrawable(R.drawable.homebutton1)).setContent(intent);
tabHost.addTab(spec);
// Do the same for the other tabs
intent = new Intent().setClass(this,PastEvents.class);
spec = tabHost.newTabSpec("PastEvents").setIndicator("PastEvents",
getResources().getDrawable(R.drawable.bank_transaction1))
.setContent(intent);
tabHost.addTab(spec);
tabHost.setCurrentTab(0);
}

I've implemented tab layout it works, but when I add tab swipe. it freeze I can't use the other tabs in the tab layout. Any suggestions.
Here's my code for the tab layout
public class TabLayoutAdmin extends TabActivity {
private TabHost mTabHost;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tablayoutadmin);
Resources res= getResources();
TabHost tabHost = getTabHost();
Intent confirmedList = new Intent().setClass(this, Reservations.class);
TabHost.TabSpec tabSpecConfirmedList= tabHost
.newTabSpec("Android")
.setIndicator("", res.getDrawable(R.drawable.stadimumspage))
.setContent(confirmedList);
Intent stadiumsPage = new Intent().setClass(this, StadiumsPage.class);
TabHost.TabSpec tabSpecStadiumsPage = tabHost
.newTabSpec("Apple")
.setIndicator("", res.getDrawable(R.drawable.newreservation))
.setContent(stadiumsPage);
Intent newReservation = new Intent().setClass(this, NewReservation.class);
TabHost.TabSpec tabSpecNewReservation= tabHost
.newTabSpec("Windows")
.setIndicator("", res.getDrawable(R.drawable.confirmedlist))
.setContent(newReservation);
Intent blockTeam = new Intent().setClass(this, Block_Team.class);
TabHost.TabSpec tabSpecBlockTeam = tabHost
.newTabSpec("Berry")
.setIndicator("", res.getDrawable(R.drawable.blockteam))
.setContent(blockTeam);
// add all tabs
tabHost.addTab(tabSpecConfirmedList);
tabHost.addTab(tabSpecStadiumsPage);
tabHost.addTab(tabSpecNewReservation);
tabHost.addTab(tabSpecBlockTeam);
//set Windows tab as default (zero based)
tabHost.setCurrentTab(0);
}
As for tab swipe I used this code

Thanks
You should use TabLayout to hold the fragments and ViewPager for swipe, here's how to do it step by step: tablayout with viewpager
I have a tabhost created by
this.tabHost = getTabHost();
// Resusable TabSpec for each tab
Intent intent; // Reusable Intent for each tab
// Create an Intent to launch the first Activity for the tab (to be reused)
intent = new Intent().setClass(this, FirstGroup.class);
// Initialize a TabSpec for the first tab and add it to the TabHost
spec1 = tabHost.newTabSpec("FirstGroup").setIndicator("Regionlar",
getResources().getDrawable(R.drawable.region2)) // Replace null with R.drawable.your_icon to set tab icon
.setContent(intent);
tabHost.addTab(spec1);
And I want to change label of tabhost programmatically: "Regionlar" to "newMenuTabbar". I couldn't find any example. thanks for attention.
Edit:
I want to change second tabitem's label from "Mənzərələr"=> "secondTabitem"
intent = new Intent().setClass(this, FirstGroup.class);
// Initialize a TabSpec for the first tab and add it to the TabHost
spec1 = tabHost.newTabSpec("FirstGroup").setIndicator("Regionlar",
getResources().getDrawable(R.drawable.region2)) // Replace null with R.drawable.your_icon to set tab icon
.setContent(intent);
tabHost.addTab(spec1);
// Create an Intent to launch an Activity for the tab (to be reused)
intent = new Intent().setClass(this, SecondActivityGroup.class);
spec2 = tabHost.newTabSpec("SecondActivityGroup").setIndicator("Mənzərələr",
getResources().getDrawable(R.drawable.img_gallery_icon)) // Replace null with R.drawable.your_icon to set tab icon
.setContent(intent);
tabHost.addTab(spec2);
Try this:
final TextView label = (TextView) tabHost.getTabWidget().findViewById(android.R.id.title);
label .setText(YOUR NEW LABEL);
Hope it will help.
b.i 's code can only change the first tab's title.
I think this is a more straight way to get the thing done:
((TextView) mTabHost.getTabWidget().getChildTabViewAt(position)
.findViewById(android.R.id.title))
.setText(yourTitle);
where position is the position of the tab and yourTitle is the title you wish to set for the tab. If you want to change the text for the current tab, then instead of replacing position by getCurrentTab, you can just replace getTabWidget().getChildTabViewAt(position)
by getCurrentTabView()
Whoever wrote this should have defined a setTabText(int position, String text) method, otherwise who would know they have a text view id'ed android.R.id.title? Or if they already had, please enlighten me.
Try this code
public class SlideMainActivity extends TabActivity {
public static RelativeLayout headerLayout;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
setContentView(R.layout.main_silde_tab);
getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE,
R.layout.hd_header);
setTabs();
}
private void setTabs() {
addTab("FirstGroup", R.drawable.tab_home, FirstGroup.class);
addTab("Regionlar", R.drawable.tab_search, Regionlar.class);
}
private void addTab(String labelId, int drawableId, Class<?> c) {
TabHost tabHost = getTabHost();
Intent intent = new Intent(this, c);
TabHost.TabSpec spec = tabHost.newTabSpec("tab" + labelId);
View tabIndicator = LayoutInflater.from(this).inflate(
R.layout.tab_indicator, getTabWidget(), false);
TextView title = (TextView) tabIndicator.findViewById(R.id.title);
title.setText(labelId);
ImageView icon = (ImageView) tabIndicator.findViewById(R.id.icon);
icon.setImageResource(drawableId);
spec.setIndicator(tabIndicator);
spec.setContent(intent);
tabHost.addTab(spec);
}
}
I have TabActivity with tabs on bottom which is composed of several different activities like this:
public class HomeScreen extends TabActivity {
private TabHost mTabHost;
#Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
try{
setContentView(R.layout.hometabs);
Resources res = getResources(); // Resource object to get Drawables
mTabHost = getTabHost(); // The activity TabHost
TabHost.TabSpec spec; // Reusable TabSpec for each tab
Intent intent; // Reusable Intent for each tab
String strName;
// Create an Intent to launch an Activity for the tab (to be reused)
strName=Central.Res.getString(R.string.tab_Books);
intent = new Intent().setClass(this, BookList.class);
spec = mTabHost.newTabSpec(strName).setIndicator("",
res.getDrawable(R.drawable.ic_menu_database))
.setContent(intent);
mTabHost.addTab(spec);
// Create an Intent to launch an Activity for the tab (to be reused)
strName=Central.Res.getString(R.string.tab_Questions);
intent = new Intent().setClass(this, QuestionsList.class);
intent.putExtra("NoteType", UserDataSQLHelper.NOTE_TYPE_QUEST );
spec = mTabHost.newTabSpec(strName).setIndicator("",
res.getDrawable(R.drawable.ic_menu_dialog))
.setContent(intent);
mTabHost.addTab(spec);
My problem is that I have the same window title for every tab. This window title is set to application name.
I need to be able to change this title to the name of the tab.
I am trying to do it by calling setTitle("MyTitle"); in onCreate() of corresponding activity and by overriding TabActivity onChildTitleChanged:
public void onChildTitleChanged(Activity childActivity, CharSequence title)
{
View tabView = mTabHost.getCurrentTabView();
int idTitle = android.R.id.title;
TextView tvTitle = (TextView) tabView.findViewById(idTitle);
tvTitle.setText(title);
}
But the result I get isn't what I need - it sets text to tab under the tab icon.
Could you please help me?
try with following code,
tabHost.setOnTabChangedListener(new OnTabChangeListener() {
#Override
public void onTabChanged(String tabId) {
Log.i("Tab id", ""+tabId);
setTitle(tabId);
}
});
setIndicator (CharSequence label, Drawable icon).
Use this function and the label will be shown as a title.
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.
