MainActivity.java

public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is 
   present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    MenuItem menuItem = menu.findItem(R.id.action_share);
    shareActionProvider =
 (ShareActionProvider)MenuItemCompat.getActionProvider(menuItem);
    EditText e1 = (EditText)findViewById(R.id.send);
    String msg = e1.getText().toString();
    setIntent(msg);
    return super.onCreateOptionsMenu(menu);
}

private void setIntent(String text){
    Intent intent = new Intent(Intent.ACTION_SEND);
    intent.setType("text/plain");
    intent.putExtra(Intent.EXTRA_TEXT,text);
    shareActionProvider.setShareIntent(intent);
}

At the time onCreateOptionsMenu() is called, the user has not had an opportunity to interact with the EditText yet, and so it will be empty (or whatever default value you might have put in it).

You can call addTextChangedListener() on the EditText to find out as the user types, then update the Intent in the ShareActionProvider based on that value, as I demonstrate in this sample app . The one-and-only activity is fairly short:
