Android:adding swipe functionality to existing tab menu? -

is possible add swipe functionality existing tab menu? i.e. swipe left or right move between tabs rather clicking on tab.

i have exisiting 3 tab menu , not want alter it's structure, love add swipe functionality.

how can 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 menu; adds items action bar if 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 , sets onclick listeners buttons      */     public void initialisevars() {          // setting 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 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 make sure opens med screen             intent openmedsearch = new intent(                     "com.example.brianapp.meditationsearchhome");             // start activity             startactivity(openmedsearch);              break;          case r.id.btnsearchhomeattvalues:              // change make sure opens med screen             intent openattsearch = new intent(                     "com.example.brianapp.attentionsearchhome");             // start activity             startactivity(openattsearch);             break;          case r.id.btnsearchhomescore:              // change make sure opens med screen             intent openscoresearch = new intent(                     "com.example.brianapp.searchscore");             // start activit             startactivity(openscoresearch);              break;          }// switch end      }  } 

i can provide following snippet. please note haven't tested it. wanted show how approach 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 next = n, n=number of tabs         }         else{             next = current - 1; //todo check next = -1         }         setcurrenttab(next);    // tabhost.setcurrenttab()     } }
