Load Data to Spinner view in Android

This is a simple example to load spinner view by an array-list.

First of all we need to create an android project. (I used eclipse)
File > New > Android Application Project


Then we need to declare an array-list in order to load values in spinner view. create array-list on Strings.xml file located under values folder.




Here the simple array-list in Strings.xml

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

    <string name="app_name">Load Spinner</string>
    <string name="action_settings">Settings</string>
    <string name="hello_world">Hello world!</string>
    <string name="fruits_prompt">Choose a fruit</string>
    
    <string-array name="fruits" >
    <item >Apple</item>  
    <item >Mango</item>
    <item >Orange</item>
    <item >Pineapple</item>   
    </string-array>

</resources>

Now add spinner view and Auto complete text view inside activity_main.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"
    tools:context=".MainActivity" >
    
    <AbsoluteLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
        
        <Spinner
            android:id="@+id/spinner1"
            android:layout_width="116dp"
            android:layout_height="40dp"
            android:layout_x="22dp"
            android:layout_y="111dp"
            android:entries="@array/fruits"
            android:prompt="@string/fruits_prompt"
            android:visibility="visible" />

       <AutoCompleteTextView
            android:id="@+id/txtFruitName"
            android:layout_width="184dp"
            android:layout_height="wrap_content"
            android:layout_x="23dp"
            android:layout_y="160dp"
            android:ems="10"
            android:hint="Fruit" >
            <requestFocus />
        </AutoCompleteTextView>
        
    </AbsoluteLayout>
</RelativeLayout>

Finally edit the MainActivity.java file to load the spinner view and get the selected text to the text field.

package com.example.loadspinner;

import android.os.Bundle;
import android.app.Activity;
import android.view.View;
import android.view.WindowManager;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;
import android.widget.Spinner;

public class MainActivity extends Activity {

 Spinner spinner1;
 AutoCompleteTextView selectedtxt;
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  
  spinner1 = (Spinner) findViewById(R.id.spinner1);
  selectedtxt = (AutoCompleteTextView) findViewById(R.id.txtFruitName);
  
  
  spinner1 = (Spinner) findViewById(R.id.spinner1);
  @SuppressWarnings("rawtypes")
  ArrayAdapter adapter = ArrayAdapter.createFromResource(this,
    R.array.fruits, android.R.layout.simple_spinner_item);
  adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
  spinner1.setAdapter(adapter);
  
  spinner1.setOnItemSelectedListener(new OnItemSelectedListener() {

   public void onNothingSelected(AdapterView<?> parentView) {

   }
   @Override
   public void onItemSelected(AdapterView<?> arg0, View arg1,
     int arg2, long arg3) {
    getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
    String text = spinner1.getSelectedItem().toString();
    selectedtxt.setText(text);  
   } 
  });
 }
}

Now we are done with coding. Run the app
