How to change Tab according to Intent in android?

I have a Activity named as Wallet and have a Activity named as CRechargeMain which adds two frgament named as "Mobile","Data";what I want in Wallet screen I have a Listview in which in case 0: when I click I want to go to CRechargeMain and show"Mobile" tab and in case 1 : when I click I want to go CRechareMain and open tab " data" .how can I do that
code for wallet:-
m_listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
switch (position) {
case 0:
Intent mMobileRecharges = new Intent(CMyWalletScreen.this,CRechargeMain.class);
startActivity(mMobileRecharges);
break;
case 1:
Intent mDataRecharge = new Intent(CMyWalletScreen.this,CRechargeMain.class);
startActivity(mDataRecharge);
break;
case 2:
Intent m_Earning= new Intent(CMyWalletScreen.this,CWalletTransactionScreen.class);
startActivity(m_Earning);
break;
}
}
});
code for CRechargeMain:-
public class CRechargeMain extends AppCompatActivity {
View m_Main;
private ViewPager m_ViewPager;
private Toolbar m_ToolBar;
private String[]actonBar={"Mobile Recharge","Mobile Data Recharge"};
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.recharge_main);
init();
}
public void init() {
m_ToolBar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(m_ToolBar);
//noinspection ConstantConditions
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowTitleEnabled(false);
m_ToolBar.setTitle("Mobile Recharge");
TabLayout m_TabLayout = (TabLayout) findViewById(R.id.tab_layout);// finding Id of tablayout
m_TabLayout.addTab(m_TabLayout.newTab().setText("Mobile"));// add deal listin tab
m_TabLayout.addTab(m_TabLayout.newTab().setText("Data Card"));// add stories tab
m_TabLayout.setTabGravity(TabLayout.GRAVITY_FILL);// setting Gravity of Tab
m_ViewPager = (ViewPager) findViewById(R.id.pager);//finding Id of ViewPager
CRechargePager m_oMobilePager = new CRechargePager
(getSupportFragmentManager(), m_TabLayout.getTabCount());
m_ViewPager.setAdapter(m_oMobilePager);// adiing adapter to ViewPager
m_ViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(m_TabLayout));// performing action of page changing
m_TabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override
public void onTabSelected(TabLayout.Tab tab) {
m_ViewPager.setCurrentItem(tab.getPosition());
m_ToolBar.setTitle(actonBar[tab.getPosition()]);
}
#Override
public void onTabUnselected(TabLayout.Tab tab) {
}
#Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_wallet, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
// Respond to the action bar's Up/Home button
case android.R.id.home:
finish();
return true;
}
return super.onOptionsItemSelected(item);
}
}

You can use the same intent and select tab based on the intent argument in your activity.

As my assumption you are having two activity, activity1 contains list and activity2 contains fragments.from activity1 based on conditions you have to jump to activity2 (fragments).Just call as below
Intent i =New Intent(this,CRechargeMain.class);
i.putExtra("",0);
startActivity(i);
In Activty2 on create method based on conditions you have to set fragment to load.
FragmentManager FM = getFragmentManager();
FM.beginTransaction().replace(R.id.content_frame, detail).commit();

Intent mMobileRecharges = new Intent(CMyWalletScreen.this,CRechargeMain.class);
intent.putExtra("doWhat", 0);
Intent mDataRecharge = new Intent(CMyWalletScreen.this,CRechargeMain.class);
intent.putExtra("doWhat", 1);
In your receiving activity:
int iDoWhat = intent.getIntExtra("doWhat", -1);
Then make your decision based on the value of iDoWhat.
int iDoWhat = getIntent().getIntExtra("doWhat",-1);
switch (iDoWhat) {
case -1:
//select tab 0
break;
case 0:
//select tab 0
break;
case 1:
//select tab 1
break;
}
You have to write the code for selecting the tab now you know which one.

Android:adding swipe functionality to existing tab menu?

Is it possible to add a swipe functionality to an existing Tab Menu? i.e. swipe left or right to move between the tabs rather than clicking on a tab.
I already have an exisiting 3 tab menu and do not want to greatly alter it's structure, but would love to add the swipe functionality.
How can I do so?
Main Menu/TabHost:
public class MainMenu extends TabActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TabHost tabHost = (TabHost)findViewById(android.R.id.tabhost);
TabSpec tab1 = tabHost.newTabSpec("Games");
Intent tab1Intent = new Intent(this, firstActivity.class);
tab1.setContent(tab1Intent);
tab1.setIndicator("Games");
TabSpec tab2 = tabHost.newTabSpec("Search");
Intent tab2Intent = new Intent(this, secondActivity.class);
tab2.setContent(tab2Intent);
tab2.setIndicator("Search");
TabSpec tab3 = tabHost.newTabSpec("Summary");
Intent tab3Intent = new Intent(this, thirdActivity.class);
tab3.setContent(tab3Intent);
tab3.setIndicator("Summary");
tabHost.addTab(tab1);
tabHost.addTab(tab2);
tabHost.addTab(tab3);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
Example of tab (middle tab):
public class secondActivity extends ActionBarActivity implements View.OnClickListener {
TextView instruction;
Button date;
Button game;
Button med;
Button att;
Button score;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.second_tab);
initialiseVars();
}
/**
* Initialises vars and sets onclick listeners for buttons
*/
public void initialiseVars() {
// setting up vars
instruction = (TextView) findViewById(R.id.tvSearchHome);
date = (Button) findViewById(R.id.btnSearchHomeDate);
game = (Button) findViewById(R.id.btnSearchHomeGame);
med = (Button) findViewById(R.id.btnSearchHomeMedValues);
att = (Button) findViewById(R.id.btnSearchHomeAttValues);
score = (Button) findViewById(R.id.btnSearchHomeScore);
// set on click listeners for the buttons
date.setOnClickListener(this);
game.setOnClickListener(this);
med.setOnClickListener(this);
att.setOnClickListener(this);
score.setOnClickListener(this);
}
public void onClick(View v) {
switch (v.getId()) {
case R.id.btnSearchHomeDate:
Intent openDateSearch = new Intent(
"com.example.brianapp.SearchDate");
// Start activity
startActivity(openDateSearch);
break;
case R.id.btnSearchHomeGame:
Intent openGameSearch = new Intent(
"com.example.brianapp.SearchGame");
// Start activity
startActivity(openGameSearch);
break;
case R.id.btnSearchHomeMedValues:
// change this to make sure it opens the med screen
Intent openMedSearch = new Intent(
"com.example.brianapp.MeditationSearchHome");
// Start activity
startActivity(openMedSearch);
break;
case R.id.btnSearchHomeAttValues:
// change this to make sure it opens the med screen
Intent openAttSearch = new Intent(
"com.example.brianapp.AttentionSearchHome");
// Start activity
startActivity(openAttSearch);
break;
case R.id.btnSearchHomeScore:
// change this to make sure it opens the med screen
Intent openScoreSearch = new Intent(
"com.example.brianapp.SearchScore");
// Start activit
startActivity(openScoreSearch);
break;
}// switch end
}
}

I can just provide you with the following snippet. Please note that I haven't tested it. I just wanted to show how I would approach this problem.
public class MainMenu extends TabActivity implements GestureDetector.OnGestureListener{
...
#Override
public boolean onFling(MotionEvent e0, MotionEvent e1, float arg2, float arg3) {
...
int current = getCurrentTab(); // TabHost.getCurrentTab()
int next;
if(e0.getRawX() - e1.getRawX() < 0 ){
//fling right
next = current + 1; //TODO check for next = n, n=number of tabs
}
else{
next = current - 1; //TODO check for next = -1
}
setCurrentTab(next); // TabHost.setCurrentTab()
}
}

Update menu when switchig between tabs in Android

I have two tabs in my application and I want the menu to change depending on the Tab.
TabHost tabHost = tabHost = getTabHost();
TabSpec photospec = tabHost.newTabSpec("Photos");
photospec.setIndicator("Photos", getResources().getDrawable(R.drawable.photo));
Intent photosIntent = new Intent(this, Photos.class);
photospec.setContent(photosIntent);
TabSpec songspec = tabHost.newTabSpec("Songs");
songspec.setIndicator("Songs", getResources().getDrawable(R.drawable.songs));
Intent songsIntent = new Intent(this, Songs.class);
songspec.setContent(songsIntent);
tabHost.addTab(photospec); // Adding photos tab
tabHost.addTab(songspec); // Adding songs tab
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int currentTab = tabHost.getCurrentTab();
if (currentTab == 0)
startActivity(new Intent(this, Photosoptions.class));
if (currentTab == 1)
{
startActivity(new Intent(this, Songsoptions.class));
}
return true;
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
int currentTab = tabHost.getCurrentTab();
if (currentTab == 0){
menu.clear();
inflater.inflate(R.menu.first, menu);
}
if (currentTab ==1){
menu.clear();
inflater.inflate(R.menu.second, menu);
}
return super.onPrepareOptionsMenu(menu);
}
tabHost.setOnTabChangedListener(new OnTabChangeListener(){
#Override
public void onTabChanged(String tabId) {
closeOptionsMenu();
}});
Now, when I switch to the songs tab the photos menu is still there until I click on it then the songs menu appears. I want the menu to get updated once I click on the tab

you are preparing the option menus in the TabActivity. prepare the option menus in the individual activity instead. So that when you are on that activity only the option menu for that will be shown.

How can I add horizontal swipe to a TabActivity?

I have seen some similar posts here, but I haven't found any answers. I want to add a swipe gesture to my tab activity, so that I'm able to change tabs with the gesture.
Here's my code:
public class Domiciliaria extends TabActivity
{
#Override
public void onCreate(Bundle savedInstanceState)
{
//requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_seleccion);
//ActionBar bar = getActionBar();
//bar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#cd3b05")));
final TabHost tabHost = getTabHost();
tabHost.setOnTabChangedListener(new OnTabChangeListener() {
#Override
public void onTabChanged(String tabId) {
// TODO Auto-generated method stub
setTabColor(tabHost);
}
}
);
// Tab for primera
TabSpec primeraspec = tabHost.newTabSpec("info 1");
primeraspec.setIndicator("Datos", getResources().getDrawable(R.drawable.primera));
Intent primeraIntent = new Intent(this, Parte_primera.class);
primeraspec.setContent(primeraIntent);
// Tab for segunda
TabSpec segundaspec = tabHost.newTabSpec("info 2");
segundaspec.setIndicator("Motivos", getResources().getDrawable(R.drawable.segunda));
Intent segundaIntent = new Intent(this, Parte_segunda.class);
segundaspec.setContent(segundaIntent);
// Tab for tercero
TabSpec tercerospec = tabHost.newTabSpec("info 3");
tercerospec.setIndicator("Examen", getResources().getDrawable(R.drawable.tercera));
Intent terceroIntent = new Intent(this, Parte_tercera.class);
tercerospec.setContent(terceroIntent);
// Tab for Cuarto
TabSpec cuartospec = tabHost.newTabSpec("info 4");
cuartospec.setIndicator("otro", getResources().getDrawable(R.drawable.cuarta));
Intent cuartoIntent = new Intent(this, Parte_cuarta.class);
cuartospec.setContent(cuartoIntent);
// Tab for Final
TabSpec finalspec = tabHost.newTabSpec("info 4");
finalspec.setIndicator("Final", getResources().getDrawable(R.drawable.pago));
Intent finalIntent = new Intent(this, Final.class);
finalspec.setContent(finalIntent);
// agregando TabSpec to TabHost
tabHost.addTab(primeraspec); // Adding photos tab
tabHost.addTab(segundaspec); // Adding songs tab
tabHost.addTab(tercerospec);
tabHost.addTab(cuartospec);
tabHost.addTab(finalspec);
tabHost.getTabWidget().setStripEnabled(true);
tabHost.getTabWidget().setRightStripDrawable(R.drawable.barra_mamei);
tabHost.getTabWidget().setLeftStripDrawable(R.drawable.barra_mamei);
setTabColor(tabHost);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.about:
startActivity(new Intent(this, About.class));
return true;
case R.id.help:
startActivity(new Intent(this, Help.class));
return true;
case R.id.CasoEspecial:
startActivity(new Intent(this, CasoEspecial.class));
return true;
default:
return super.onOptionsItemSelected(item);
}
// respond to menu item selection
}
protected void setTabColor(TabHost tabHost) {
// TODO Auto-generated method stub
for(int i=0;i<tabHost.getTabWidget().getChildCount();i++) {
tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.parseColor("#E04006")); //unselected
}
tabHost.getTabWidget().getChildAt(tabHost.getCurrentTab()).setBackgroundColor(Color.parseColor("#fbfbf3")); // selected
}
}

You can achieve the TabSwipe using ViewPager with Fragments and ActionBar.
If you wish to work with Minimum API 11, the following link will show you how. Since API 11, ActionBar has the way to create tabs in application with fragments.
If you need to give support to the older versions, you should make use of Support Library
or ActionBarSherlock

This is the best tutorial for horizontal swipe views straight from google.
Creating Swipe Views with Tabs
I would recommened to use Fragments and FragmentActivity instead of TabActivity

Reload an activity inside tabhost

I have a tabhost and I add there 3 Activities(one activity per tab).
I need to know how to call a new intern in an activity each time i change a tab.
I added a listener for the tabhost.When I use the clearAllTabs(); method and add all the tabs again inside the listener then the app crash.
when I use code toto delete from the view the specific tab that the user clickes tabHost.getTabWidget().removeView(tabHost.getTabWidget().getChildTabViewAt(i));
tabHost.addTab(the tab I want to replace);
then the new tab is positioned in the end of the tabhost.
I just need an example of how to reload the proportionate activity each time the user clickes the specific tab.
my code:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// ActionBar bar = getSupportActionBar();
// requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
Resources res = getResources();
LocalActivityManager mlam = new LocalActivityManager(this, false);
final TabHost tabHost = (TabHost) findViewById(android.R.id.tabhost);
mlam.dispatchCreate(savedInstanceState);
tabHost.setup(mlam);
TabHost.TabSpec spec;
Intent intent;
// TabHost tabHost = getTabHost();
// tabHost.setup();
TabSpec specAll = tabHost.newTabSpec("All");
specAll.setIndicator("All");
Intent allIntent = new Intent(this, allActivity.class);
specAll.setContent(allIntent);
// specAll.setContent(R.id.allList);
Log.d("SpecAll",""+specAll.setContent(allIntent));
TabSpec specIn = tabHost.newTabSpec("in");
specIn.setIndicator("In");
Intent inIntent = new Intent(this, inActivity.class);
specIn.setContent(inIntent);
TabSpec specOut = tabHost.newTabSpec("Out");
specOut.setIndicator("Out");
Intent outIntent = new Intent(this, outActivity.class);
specOut.setContent(outIntent);
// Adding all TabSpec to TabHost
tabHost.addTab(specAll); // Adding all tab
tabHost.addTab(specIn); // Adding in tab
tabHost.addTab(specOut); // Adding out tab
tabHost.setOnTabChangedListener(new OnTabChangeListener() {
#Override
public void onTabChanged(String tabId) {
int i = tabHost.getCurrentTab();
//Log.i("######## ANN CLICK TAB NUMBER", "------" + i);
if (i == 0) {
Log.d("TAB","" +i);
} else if (i == 1) {
Log.d("TAB","" +i);
}
else
Log.d("TAB", ""+i);
}
});
}

It seems there is a matter with activity and tabhost.in order to reload an activity you just have to do:
specAll.setContent(yourIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
Just before the tabHost.addTab

In my simple case when I do not need to persist tab fragments I use the next code
int currentTabId = mTabHost.getCurrentTab();
mTabHost.clearAllTabs();
setupTabs();
mTabHost.setCurrentTab(currentTabId);

I also face the same problem but i resolve this issue like this way...
This is my TabActivity....
public class MainActivity extends TabActivity {
TabHost tabhost;
String cTab = "0";
String nTab;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
tabhost = getTabHost();
TabSpec one = tabhost.newTabSpec("0");
// setting Title and Icon for the Tab
one.setIndicator("", getResources().getDrawable(R.drawable.ic_launcher));
Intent songsIntent = new Intent(this, FirstActivity.class);
one.setContent(songsIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
one.setContent(songsIntent);
TabSpec two = tabhost.newTabSpec("1");
// setting Title and Icon for the Tab
two.setIndicator("", getResources().getDrawable(R.drawable.ic_launcher));
Intent songsIntent1 = new Intent(this, SecondActivity.class);
two.setContent(songsIntent1.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
two.setContent(songsIntent1);
TabSpec three = tabhost.newTabSpec("2");
// setting Title and Icon for the Tab
three.setIndicator("",
getResources().getDrawable(R.drawable.ic_launcher));
Intent songsIntent4 = new Intent(this, ThirdActivity.class);
three.setContent(songsIntent4.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
three.setContent(songsIntent4);

// setting Title and Icon for the Tab
four.setIndicator("", getResources()

Intent songsIntent5 = new Intent(this, FourthActivity.class);
four.setContent(songsIntent5.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
four.setContent(songsIntent5);
tabhost.addTab(one);
tabhost.addTab(two);
tabhost.addTab(three);
tabhost.addTab(four);
tabhost.setOnTabChangedListener(new OnTabChangeListener() {
#Override

}
});
int numberOfTabs = tabhost.getTabWidget().getChildCount();

tabhost.getTabWidget().getChildAt(t)
