How to set a default text to a Spinner

I want to set the spinner to show the name country even if any other list is selected. I have used a textview which displays the selected item of the Spinner List. As I used the setselection method to set the spinner title to Country the EditText also eventually changes. I went through various topic answered regarding this but couldn't find suitable response

I am attaching my code below

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;
    }

}

My XML file

<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>

My 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>

My Requirement is whatever is selected in the spinner the Textview should display the selected Item but The spinner should always show the first item or in my case Country

mySpinner = (Spinner) findViewById(R.id.spinner);
        mySpinner.setPrompt("Categorie");
        final ArrayList<String> strDeviceArr = new ArrayList<>();

        mySpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                String valueSelected = mySpinner.getSelectedItem().toString();
                if(!valueSelected.equals("Categorie"))
                    Toast.makeText(MenuActivity.this, ""+valueSelected, Toast.LENGTH_SHORT).show();

            }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {

            }
        });

I done this in a simple way

  1. Add default text at adapter first or end position(in my case end ) and set this item as default selection. ---- Also get default selection position, So that no action will perform in setOnItemSelectedListener().

    taskName.add("one");
taskName.add("two");
taskName.add("select a task");
ArrayAdapter<String> adapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_dropdown_item, taskName);
binding.spnTask.setAdapter(adapter);
binding.spnTask.setSelection(adapter.getPosition("select a task name"));
final int defaultPosition = binding.spnTask.getSelectedItemPosition();

  2. Check selected position is default text position 

      binding.spnTask.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

        if (position == defaultPosition) {
            Toast.makeText(this, "No Action", Toast.LENGTH_SHORT).show();
        }else{  Toast.makeText(this, "Your Action" , Toast.LENGTH_SHORT).show();   }
    }

    @Override
    public void onNothingSelected(AdapterView<?> parent) {

    }
});

You only need 3 lines of code for this:

(1) Declare a global variable that is used to save and load the spinner item ID. By global, I mean declaring it right after "public class MainActivity extends Activity {".

int mySpinner_selectedId;

(2) Then, add the following code AFTER the user has made his/her choice. One good location would be a button that appears together with your spinner.

mySpinner_selectedId = mySpinner.getSelectedItemPosition();

(3) Finally, add the following code right after "mySpinner.setAdapter(adapter);" to load the last selected item.

mySpinner.setSelection(mySpinner_selectedId);

You're most welcomed.

Try this:

    public void onItemSelected(AdapterView<?> parent, View view, 
        int pos, long id) {

           spinner.setSelection(pos);

    }

Do it this way. After setting the textView setSelection to 0th position of your spinner list

sp.setOnItemSelectedListener(new OnItemSelectedListener() {

    @Override
    public void onItemSelected(AdapterView<?> arg0, View arg1,
        int arg2, long arg3) {

        selected = sp.getSelectedItem().toString();
        System.out.println(selected);
        t.setText(selected);
        sp.setSelection(0);
    }
}

Try this way.

sp.setOnItemSelectedListener(new OnItemSelectedListener() {

    @Override
    public void onItemSelected(AdapterView<?> arg0, View arg1,
            int arg2, long arg3) {
        //selected = sp.getSelectedItem().toString();
        //System.out.println(selected);
        if(arg2!=0)
           t.setText(sp.getSelectedItem().toString());
        sp.setSelection(0);
    }
}

I hope this will help you. Let me know what happens. Thank you.

Use this code

declaration

String selected, spinner_item;

spinner code 

sp.setOnItemSelectedListener(new OnItemSelectedListener() {

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

            setid();
        }

        private void setid() {
            sp.setSelection(sp_position);
            t.setText(spinner_item);
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {

        }
    });
