        this.myAuto=(AutoCompleteTextView)super.findViewById(R.id.myAuto);
        this.myAuto.setAdapter(adapter);

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
