    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) {

        }
    });

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

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.

That is the defualt value if the extra cannot be read. So your if/case statement on the receiving side can handle the error. e.g. display a default tab if 0 or 1 not sent. – usajnf Jun 13 '16 at 12:06

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();
