change a fragment by pressing ImageView Button

Question

I have four fragments (in two packages) and its corresponding four xml files. I have set three of them accordingly to tabselect. One fragement (ComapreFrag.java) has an ImagineView button. When I press on it, I want to show a new Fragment (CreditCards.java). How can I do this? Find below the code I used.

MainActivity.java

 import android.support.v4.app.Fragment;

package com.example.swipetabs;

import com.tabs.*;

import android.os.Bundle;
import android.app.ActionBar;
import android.app.ActionBar.Tab;

public class MainActivity extends FragmentActivity implements TabListener {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //

        viewPager=(ViewPager)findViewById(R.id.pager);
        //intialise fragement
        
    
        viewPager.setAdapter(new MyAdoptor(getSupportFragmentManager()));
        viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {

        //action_bar.setBackgroundDrawable(d)
        action_bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
        
        ActionBar.Tab tab1=action_bar.newTab();

Try This in click event

   FragmentTransaction fm=getSupportFragmentManager().beginTransaction();     
   fm.replace(R.id.tabcontent, new Myprofile());        
   fm.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
   fm.addToBackStack(null);
   fm.commit();

@David when i add this code to onClick(View v) i got lot of Errors. – VenushkaT Feb 05 '14 at 09:43
Can you list some error messages? BTW: you should @VenushkaT, and I simply formatted the code. – David Feb 05 '14 at 09:45
@David ype mismatch: cannot convert from android.support.v4.app.FragmentTransaction to android.app.FragmentTransaction – VenushkaT Feb 05 '14 at 09:47
@VenushkaT you might import wrong package, not sure and good luck. – David Feb 05 '14 at 09:48
@David i put this code under public void switchToFragmentB() MainActivity.java – VenushkaT Feb 05 '14 at 09:48
import android.support.v4.app.FragmentManager; import this package – Palak Feb 05 '14 at 09:48
@Palak i have alredy imported it in my MainActivity.java class – VenushkaT Feb 05 '14 at 09:51
Check out that same fragment package is used in your fragment class (import android.support.v4.app.Fragment;) – Palak Feb 05 '14 at 09:52
