         resultIntent.putExtra(body, true);

NoteView class

      public boolean onOptionsItemSelected(MenuItem item) {

          switch (item.getItemId()) {
    case DIARY_EDIT:
         Intent i = new Intent(NoteView.this, NoteEdit.class);
         i.putExtra(NotesDbAdapter.KEY_ROWID, mRowId);
         startActivityForResult(i, ACTIVITY_VIEWERS);
         break;
          }  }

         @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
        super.onActivityResult(requestCode, resultCode, intent);
        switch(requestCode) {   
        case (ACTIVITY_VIEWERS) 
        : {      
            if (resultCode == Activity.RESULT_OK)
            {    
                Bundle extras = getIntent().getExtras();
                 newText =extras.getString(NotesDbAdapter.KEY_BODY);  
                // TODO Update your TextView.   
                }       
            break;    
            }

NoteEdit class:

//write this code when edit finished
Intent resultIntent = new Intent(getIntent()); // Note this line is important!
String body = mBodyText.getText().toString()

resultIntent.putExtra(NotesDbAdapter.KEY_BODY, body); 
setResult(RESULT_OK,resultIntent);
finish();

NoteView class: 

public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    case DIARY_EDIT:
        Intent i = new Intent(NoteView.this, NoteEdit.class);
        i.putExtra(NotesDbAdapter.KEY_ROWID, mRowId);
        startActivityForResult(i, ACTIVITY_VIEWERS);
        break;
    }
}



@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);
    switch(requestCode) {
    case ACTIVITY_VIEWERS: {
        if (resultCode == RESULT_OK) {
            Bundle extras = intent().getExtras();
            newText =extras.getString(NotesDbAdapter.KEY_BODY);
            // TODO Update your TextView.
        }
        break;
        }
    }
}

try something like this.

Intent resultIntent = getIntent();
String body = mBodyText.getText().toString()  
resultIntent.putExtra(body, true);
setResult(RESULT_OK,resultIntent);
finish();

dont forget to put a call to finish().

now use this code.

NoteEdit class:

Intent resultIntent = new Intent(NoteEdit.this, NoteView.class);
       String body = mBodyText.getText().toString()  
     resultIntent.putExtra(NotesDbAdapter.KEY_BODY, body); 
     setResult(RESULT_OK,resultIntent);

NoteView class:

public boolean onOptionsItemSelected(MenuItem item) {

      switch (item.getItemId()) {
case DIARY_EDIT:
     Intent i = new Intent(NoteView.this, NoteEdit.class);
     i.putExtra(NotesDbAdapter.KEY_ROWID, mRowId);
     startActivityForResult(i, ACTIVITY_VIEWERS);
     break;
      }  }

     @Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);
    switch(requestCode) {   
    case ACTIVITY_VIEWERS 
    : {      
        if (resultCode == RESULT_OK)
        {    
            Bundle extras = intent().getExtras();
             newText =extras.getString(NotesDbAdapter.KEY_BODY);  
            // TODO Update your TextView.   
            }       
        break;    
        }    
    }  


}

use setResult(Activity.RESULT_OK, resultIntent) in NodeEdit
and see http://developer.android.com/reference/android/app/Activity.html#StartingActivities
Edit
also you should use resultIntent.putExtra(NotesDbAdapter.KEY_BODY, body); in NodeEdit to pass String value body to another activity. and get it by using extras.getString(NotesDbAdapter.KEY_BODY);
