如何将默认文本设置为Spinner

我希望将下拉菜单设置为显示国家名称，即使选择了其他列表。我已经使用了一个TextView来显示Spinner List中选定的项目。当我使用setselection方法将Spinner标题设置为“Country”时，EditText也最终会更改。我查阅了各种有关此问题的主题回答，但没有找到合适的响应。
我在下面附上我的代码
MainActivity.java

package com.example.spinner;

import android.os.Bundle;
import android.app.Activity;
import android.database.Cursor;
import android.view.Menu;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.TextView;

public class MainActivity extends Activity {

    Spinner sp;
    TextView t;
    String[] country;
    int sp_position;
    String selected;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        String myString = "Country"; 

        sp = (Spinner)findViewById(R.id.spinner1);
        t = (TextView)findViewById(R.id.textView1);
        country = getResources().getStringArray(R.array.spinner);
        ArrayAdapter<String> ad = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_spinner_dropdown_item,country);   
        sp_position = ad.getPosition(myString);
        sp.setAdapter(ad);
        ad.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

        sp.setOnItemSelectedListener(new OnItemSelectedListener() {

            @Override
            public void onItemSelected(AdapterView<?> arg0, View arg1,
                    int arg2, long arg3) {
                selected = sp.getSelectedItem().toString();
                System.out.println(selected);
                setid();

            }

            private void setid() {
                sp.setSelection(sp_position);


            }

            @Override
            public void onNothingSelected(AdapterView<?> arg0) {
                // TODO Auto-generated method stub

            }
        });

        t.setText(selected);

    }




    @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;
    }

}

我的XML文件

<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"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginLeft="48dp"
        android:layout_marginTop="69dp"
        android:maxLines="4"
        android:hint="Address" />

    <Spinner
        android:id="@+id/spinner1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignRight="@+id/textView1"
        android:layout_below="@+id/textView1"
        android:layout_marginTop="72dp" 
        />

</RelativeLayout>

我的STRINGS.XML

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <string name="app_name">Spinner</string>
    <string name="action_settings">Settings</string>
    <string name="hello_world">Hello world!</string>
    <string-array name="spinner">
        <item>Country</item>
        <item>India</item>
        <item>Russia</item>
        <item>USA</item>
        <item>France</item>
        <item>United Kingdom</item>
    </string-array>
<string name ="Country">Country</string>
</resources>

我的需求是，无论在Spinner中选择什么，TextView都应该显示所选的项目，但Spinner始终应该显示第一项，或者在我的情况下显示国家。
