Spinner in Android/Spinner Example/Simple Spinner Program


Spinner is a widget similar to a drop-down list for selecting items. 

Create an array of items to be  displayed
String androidphones[]={"Sony Ericson Xperia","Motorola Droid", "Samsung Galaxy","HTC Sensation","LG Nitro","Google Nexus"};

Add an array adapter to display the spinner
spinner.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item,androidphones));

In spite of android.R.layout.simple_spinner_item, you can also add

android.R.layout.simple_spinner_dropdown_item
                          or
android.R.layout.simple_dropdown_item_1line

Source code


main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<LinearLayout
android:id="@+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content">
    <TextView
    android:text="Select Phone"
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
    </TextView>
    <Spinner
    android:id="@+id/spinner1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_weight="1">
    </Spinner>
</LinearLayout>
</LinearLayout>


SpinnerExampleActivity.java
package com.example.SpinnerActivity;

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

public class SpinnerExampleActivity extends Activity {
      Spinner spinner;
       String androidphones[]={"Sony Ericson Xperia","Motorola Droid", "Samsung Galaxy","HTC Sensation","LG Nitro","Google Nexus"};
     
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        spinner=(Spinner)findViewById(R.id.spinner1);
        spinner.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line,androidphones));
        spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
            public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
                int item = spinner.getSelectedItemPosition();
                Toast.makeText(getBaseContext(),
                    "You have selected the book: " + androidphones[item],
                    Toast.LENGTH_SHORT).show();
            }


            public void onNothingSelected(AdapterView<?> arg0) {
            }
        });
    }


   
}

Thread thread = new Thread(){     public void run(){       System.out.println("This is a thread");     }   }     thread.start(); So when coming to android, before learning about coroutines we need to discuss some scenarios. Normally how an app works when user launch an application. When user launchers the application, a main thread is created. This thread is intended to do small operations like button clicks, UI interaction , small mathematical operations. We cant perform long running op...
