how to set text of an EditText view in multiple used fragments?

Question

i am creating an app that has a tabbed interface using TabHost and fragments, and the user needs to select the time using a TimePickerDialog and the selected time is populated into an EditText view, so i moved the time picker to a fragment so i can use it in multiple tabs which works but the problem is when i set the time using the dialog EditText view that is populated is the one in the last tab not the one the TimePickerDialog was opened from, how do i deal with this?

here is the layout for time picker fragment

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
         xmlns:tools="http://schemas.android.com/tools"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         tools:context="com.ztech.fakecallm.TimePickerFragment">
<EditText
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:inputType="time"
        android:ems="10"
        android:id="@+id/timePicker"
        android:focusable="false"
        android:hint="@string/time"
        android:onClick="onClickTime"
        android:layout_marginLeft="20dp"
        android:layout_marginRight="20dp"
        android:layout_alignParentStart="true"
        android:layout_alignParentEnd="true"/>
</RelativeLayout>

and here is the code that populates the EditText view which is stored in MainActivity.java

public void onClickTime(View view) {

    final Calendar c = Calendar.getInstance();

    int cHour = c.get(Calendar.HOUR_OF_DAY);

    int cMinute = c.get(Calendar.MINUTE);

    TimePickerDialog timePickerDialog = new TimePickerDialog(this, new TimePickerDialog.OnTimeSetListener() {
        @Override
        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

            c.set(Calendar.HOUR_OF_DAY, hourOfDay);

            c.set(Calendar.MINUTE, minute);

            scheduleDate = c.getTime();

            SimpleDateFormat dateFormat = new SimpleDateFormat("hh:mm a", Locale.US);

            EditText timeInput = (EditText)findViewById(R.id.timePicker);

            timeInput.setText(dateFormat.format(scheduleDate));

        }
    }, cHour, cMinute, false);

    timePickerDialog.show();

}

and here is the layout of the fragment that represents the first tab

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

use this

enter link description here

   dependencies {
  compile 'com.wdullaer:materialdatetimepicker:2.3.0'
}

and

Implement your fragment an OnTimeSetListener

and in fragment to show TimePickerDialog

Calendar now2 = Calendar.getInstance();
                TimePickerDialog tpd = TimePickerDialog.newInstance(
                        NewActivity.this, now2.get(Calendar.HOUR_OF_DAY), now2.get(Calendar.MINUTE),
                        now2.get(Calendar.SECOND), false
                );
                tpd.show(getFragmentManager(), "Select Time");

And

@Override
public void onTimeSet(RadialPickerLayout view, int hourOfDay, int minute) {
  String time = "You picked the following time: "+hourOfDay+"h"+minute;
  timeTextView.setText(time);
}

how to set text of an EditText view in multiple used fragments?
