Sending a value from one fragment to another fragment.

Question

In FirstFragment I have an on click listener that does an equation and sends a value to an EditText within FirstFragment. I want to get that value in a EditText in SecondFragment under the same activity (but each fragment has their own .Java).

This is activity_testing.xml.

'''

android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/viewPager" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.example.dfsdfd.MainActivity" >

'''

This is the Testing.Java ''' public class Testing extends FragmentActivity {

public void saveData(int id, Bundle data) {
    // based on the id you'll know which fragment is trying to save data(see
    // below)
    // the Bundle will hold the data
}

public Bundle getSavedData() {
    return null;
    // here you'll save the data previously retrieved from the fragments and
    // return it in a Bundle

}


protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_testing);

    ViewPager pager = (ViewPager) findViewById(R.id.viewPager);
    pager.setAdapter(new MyPagerAdapter(getSupportFragmentManager()));
}

private class MyPagerAdapter extends FragmentPagerAdapter {

    public MyPagerAdapter(FragmentManager fm) {

        super(fm);
    }


    public Fragment getItem(int pos) {
        switch (pos) {

        case 0:
            return FirstFragment.newInstance("FirstFragment, Instance 1");
        case 1:
            return SecondFragment.newInstance("SecondFragment, Instance 1");

        default:
            return ThirdFragment.newInstance("ThirdFragment, Default");

        }
    }


    public int getCount() {
        return 2;
    }

    @Override
    public CharSequence getPageTitle(int position) {

        return "Step " + (position + 1);
    }
}

'''

FirstFragment ''' public class FirstFragment extends Fragment implements OnClickListener {

public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View v = inflater.inflate(R.layout.first_frag, container, false);

return v; }

public void onClick(View v) {
    // TODO Auto-generated method stub

if (US.isChecked()) {

                        double personWeight = Double.valueOf(Weight
                                .getText().toString());
                        double personFeet = 12 * Double.valueOf(Feet
                                .getText().toString());
                        double personInches = Double.valueOf(Inches
                                .getText().toString());
                        double personAge = Double.valueOf(Age.getText()
                                .toString());

                        if (Men.isChecked()) {

                            double personResults = (66
                                    + (6.23 * personWeight)
                                    + (12.7 * (personFeet + personInches)) - (6.8 * personAge));

                            results.setText("" + d.format(personResults));

                        }
                        if (Women.isChecked()) {

                            double personResults = (655
                                    + (4.35 * personWeight)
                                    + (4.7 * (personFeet + personInches)) - (4.7 * personAge));
                            results.setText("" + d.format(personResults));

                        }

                    }

'''

I would want, results = (EditText) v.findViewById(R.id.editTextFinish); to be the value in which I am trying send to the SecondFragment.

SecondFragment.Java.

''' public class SecondFragment extends Fragment {

public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.second_frag, container, false);

    return v;
}

public static SecondFragment newInstance(String text) {

    SecondFragment f = new SecondFragment();
    Bundle b = new Bundle();
    b.putString("msg", text);

    f.setArguments(b);

    return f;
}

} '''

The second_frag.xml ''' <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@drawable/topbackgroundboom" android:orientation="vertical" >

    <EditText
        android:id="@+id/editTextFinish"
        android:layout_width="80dp"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:clickable="false"
        android:cursorVisible="false"
        android:ems="10"
        android:gravity="center"
        android:hint="BMR"
        android:inputType="none"
        android:textColor="@android:color/black" />

</LinearLayout>

'''

If there is any advice other than a reference to the android development page; or to an online tutorial. I have tried them all and even made it to page 3 on google. That is pretty desperate.

Thanks in advance!
