android – How to set a default text to a Spinner

Posted by: admin June 15, 2020 Leave a comment

Questions:

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

How to&Answers:

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) {

        }
    });

Answer:

spinner.setPrompt("Pick One");

Answer:

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.

Answer:

Use android:prompt="@string/select" in spinner….

Answer:

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);
    }
}

Answer:

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.

Answer:

Try this:

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

           spinner.setSelection(pos);

    }

Answer:

try this

Countryspinner.setOnItemSelectedListener(new OnItemSelectedListener() {

        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int position, long arg3) {
            if (position == 0) {
                txtSpinner1.setHint("Select Country");
            } else {
                txtSpinner1.setText(CountryList.get(position));
            }

        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub
            txtSpinner1.setHint("Select Country");
        }

    });

Answer:

In onItemSelected method add this code sp.setSelection(0);

Answer:

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) {
    
        }
    });
