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);
spec = tabHost.newTabSpec("songs").setIndicator("songs")
.setContent(intent);
tabHost.addTab(spec);
tabHost.setCurrentTab(2);
}

I was create android application with tab and TabHost but users cant switch between tabs via swipe.
I use TabActivity for this app. Users most click on tabs for switch between tabs or activities.
MainActivity.Java :
public class MainActivity extends TabActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Resources ressources = getResources();
TabHost tabHost = getTabHost();
//Home Intent
Intent intentHome = new Intent().setClass(this, HomeActivity.class);
TabSpec tabSpedHome = tabHost
.newTabSpec("Home")
.setIndicator("",ressources.getDrawable(R.drawable.icon_home_config))
.setContent(intentHome);
//Search Intent
Intent intentSearch = new Intent().setClass(this, SearchActivity.class);
TabSpec tabSpedSearch = tabHost
.newTabSpec("Search")
.setIndicator("",ressources.getDrawable(R.drawable.icon_search_config))
.setContent(intentSearch);
//Archive Intent
Intent intentArchive = new Intent().setClass(this, ArchiveActivity.class);
TabSpec tabSpedArchive = tabHost
.newTabSpec("Archive")
.setIndicator("",ressources.getDrawable(R.drawable.icon_archive_config))
.setContent(intentArchive);
//Download Intent
Intent intentDownload = new Intent().setClass(this, DownloadActivity.class);
TabSpec tabSpedDownload = tabHost
.newTabSpec("Download")
.setIndicator("",ressources.getDrawable(R.drawable.icon_download_config))
.setContent(intentDownload);
//Conctactus Intent
Intent intentConctactus = new Intent().setClass(this, ContactusActivity.class);
TabSpec tabSpedConctactus = tabHost
.newTabSpec("Conctact us")
.setIndicator("",ressources.getDrawable(R.drawable.icon_contactus_config))
.setContent(intentConctactus);
//AddAllTab
tabHost.addTab(tabSpedHome);
tabHost.addTab(tabSpedSearch);
tabHost.addTab(tabSpedArchive);
tabHost.addTab(tabSpedDownload);
tabHost.addTab(tabSpedConctactus);
//Set Default Tab
tabHost.setCurrentTab(0);
}
}
And activity_main.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">
<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="5dp" />
</LinearLayout>
</TabHost>
TabActivity has been deprecated for over three years. Please use another tab solution. Particularly if you want tab contents to be able to be swiped, use ViewPager for the tab contents and a tabbed indicator (e.g., PagerTabStrip) for the tabs.
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.
I am trying to get an Activity to show in a tab but just can't get it to work.
I have checked that the activity shows when on its own but as soon as I try to put it in a tab I get an empty tab.
This is the tab screen and its XML layout file:
public class TestTabs extends TabActivity{
private TabHost tabHost; // The tabhost for all the tabs
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.tabbed_screen);
tabHost = getTabHost();
initTabs();
}
protected void addTab(String tabName, Intent tabIntent){
TabSpec tabSpec = tabHost.newTabSpec(tabName);
tabSpec.setIndicator(tabName);
tabSpec.setContent(tabIntent);
tabHost.addTab(tabSpec);
}
protected void initTabs() {
addTab("1",new Intent(this,TestActivity.class));
}
}
Layout:
<?xml version="1.0" encoding="utf-8"?>
<TabHost android:layout_width="fill_parent"
android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost">
<LinearLayout android:id="#+id/LinearLayout01"
android:orientation="vertical" android:layout_height="fill_parent"
android:layout_width="fill_parent">
<TabWidget android:id="#android:id/tabs" android:layout_height="fill_parent" android:layout_width="fill_parent"></TabWidget>
<FrameLayout android:id="#android:id/tabcontent"
android:layout_height="fill_parent" android:layout_width="fill_parent">
</FrameLayout>
</LinearLayout>
</TabHost>
This is the "child" activity:
public class TestActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
// The super.onCreate() call will set the general frame also for this Screen:
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
Layout:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:ellipsize="end"
android:maxLines="1"
android:singleLine="true"
android:text="Hello World"
android:textSize="12sp"
android:textStyle="bold" />
As I said, the child activity shows ok when alone but when I put it in the tab I get the tab without any contents.
I am probably missing something obvious but this is the first time I have done anything with tabs in Android.
You should change name of method "addTab" because its default method of TabActivity that might be causing this problem.secondly,your code should be like:
public class TestTabs extends TabActivity{
private TabHost tabHost; // The tabhost for all the tabs
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.tabbed_screen);
tabHost = getTabHost();
TabSpec tabSpec;
Intent intent = new Intent().setClass(this, tab1_activity.class);
tabSpec = tabHost.newTabSpec("Tab-1").setIndicator("Tab-1",drawable1_obj).setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, tab2_activity.class);
tabSpec = tabHost.newTabSpec("Tab-2").setIndicator("Tab-2",drawable2_obj).setContent(intent);
tabHost.addTab(spec);
tabHost.setCurrentTab(1);
}
}
My tabhost tools.java:
#Override
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);
}}
Each intent calls an activity.
and within each "file. java" commands have to perform the calculations.
Within "dados.java" is where I get the information of the User.
When they click on the tab "calcular" must verify that all data has been completed.
I guess I need a "onclicklistener" for each tab, like a button, right??
How? how to create an event to run code when a tab"Dados" tab"Legenda" tab"calcular" is clicked?
Attention: I need to check which tab was clicked from the file "ToolDadosCircular.java."
Edit:
tabtools.xml code:
<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>
</TabHost>
Try
tabHost.getChildAt(yourtab).setOnClickListener(new View.onClickListener()
{
#Override public void onClick(View view){
//your code
}
}
Edit: I'm guessing your class is like this
public class ToolDadosTubuCirc extends Activity{
#Override public void onCreate(Bundle bundle){
//code...
TabHost tabHost = (TabHost) getParent().findViewById(yourTabHostId);
//do what you want with tabHost
//code...
}
}
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);
}
});
