spinner with out "select option" but it should show blank

I am creating a spinner. The spinner shows the first row value as the default text. I want the Spinner's text to be blank initially.

I could add a new empty row with list.add(" "); but I think that this approach looks ugly.

list.add("");//this make my ui ugly but with out this i can't make my spinner blank in starting.
list.add("1");//if i remove add("").then spinner take add("1") this should not happen
list.add("2");

How do I create a Spinner that initially doesn't display any text?

Update:

urineGlucoseSpinner =  (Spinner) view.findViewById(R.id.spnner_urine_glucose);
ArrayList<String> ugList = new ArrayList<String>();
ugList.add("select");
ugList.add("1.5");
ugList.add("5.5");
ugList.add("0.8");
ugList.add("9.5");
ugList.add("12.0");

//ArrayAdapter<String> urineGlucoseAdapter = new ArrayAdapter<String>(getActivity(),android.R.layout.simple_spinner_item, ugList);
ArrayAdapter<String> urineGlucoseAdapter = new ArrayAdapter<String>(getActivity(),R.layout.custom_spinner_text,ugList);
urineGlucoseAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
urineGlucoseSpinner.setAdapter(urineGlucoseAdapter);
urineGlucoseSpinner.setOnItemSelectedListener(new OnUGItemSelected());

Take image look like dropdown and put them in background of textview. 

 Textview  gender=(Textview)findViewById(R.id.gender)
  gender.setText("");
  gender.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    AlertDialog.Builder conductor = new AlertDialog.Builder(
                            Calculator.this);
                    conductor.setTitle("Select Gender");

                    int resId = getResources().getIdentifier("gender_array",
                            "array", getPackageName());
                    conductor.setItems(resId,
                            new DialogInterface.OnClickListener() {
                                public void onClick(DialogInterface dialog,
                                        int index) {                            
                                    int resId1 = getResources().getIdentifier(
                                            "gender_array", "array",
                                            getPackageName());

                                    gender.setText(getResources()
                                            .getStringArray(resId1)[index]);                                
                                }
                            });
                    AlertDialog alert = conductor.create();
                    alert.show();

                }
            });

String.xml

<string-array name="gender_array">      
        <item>Male</item>        
        <item>Female</item>          
</string-array>

Write this code in oncreate method:

Spinner gender = (Spinner) findViewById(R.id.gender);
        ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
                this, R.array.gender_array,
                android.R.layout.simple_spinner_item);
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        gender.setAdapter(adapter);
gender.setSelection(0);

and copy the below code and paste in string.xml

String.xml

<string-array name="gender_array"> 
       <item> </item>          
        <item>Male</item>        
        <item>Female</item>          
    </string-array>

it will work properly.

You should include extra entry in adapter that represents "Select" or something , and make it the initial selected item in the Spinner.

OR may be you will have to create custom spinner or something which i am not sure of.
