Today we are going to discuss about implementing Spinner widget. Spinner is a widget similar to a drop-down list for selecting items. In this tutorial,we will create a simple spinner widget that displays a list of days. When one is selected, a toast message will display the selected item. (FYI, I have taken this definition from Android.com)
main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Spinner
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/spinner1"
android:layout_margin="10dp">
</Spinner>
<RelativeLayout>
SpinnerDemoActivity.java
package com.technotalkative.spinnerdemo;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.Toast;
public class SpinnerDemoActivity extends Activity {
/** Called when the activity is first created. */
Spinner spinner1;
private static final String[] daysArray = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Utils.hideTitleBar(this);
setContentView(R.layout.main);
InitialSetUpUI();
}
// Method to initialize UI
public void InitialSetUpUI()
{
spinner1 = (Spinner) findViewById(R.id.spinner1);
ArrayAdapter adapter = new ArrayAdapter(this, android.R.layout.simple_spinner_item,daysArray);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner1.setAdapter(adapter);
spinner1.setOnItemSelectedListener(new mySpinnerListener());
}
class mySpinnerListener implements Spinner.OnItemSelectedListener
{
@Override
public void onItemSelected(AdapterView parent, View v, int position,
long id) {
// TODO Auto-generated method stub
Toast.makeText(parent.getContext(), "The day is " +
parent.getItemAtPosition(position).toString(), Toast.LENGTH_LONG).show();
}
@Override
public void onNothingSelected(AdapterView parent) {
// TODO Auto-generated method stub
// Do nothing.
}
}
}
Output:
