안드로이드 spinner 예제 따라하기

-간단한 spinner 예제이다. spinner를 활용해서 설정창을 만들어 보자.

-Java 소스

public class Ex07_SpinnerActivity extends Activity implements

OnItemSelectedListener {

ArrayList<String> arraylist;

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

arraylist = new ArrayList<String>();

arraylist.add("data0");

arraylist.add("data1");

arraylist.add("data2");

arraylist.add("data3");

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, 

android.R.layout.simple_spinner_dropdown_item, arraylist); 

                               //스피너 속성

Spinner sp = (Spinner) this.findViewById(R.id.spinner);

sp.setPrompt("골라봐"); // 스피너 제목

sp.setAdapter(adapter);

sp.setOnItemSelectedListener(this);

}

@Override

public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,

long arg3) {

// TODO Auto-generated method stub

Toast.makeText(this, arraylist.get(arg2), Toast.LENGTH_LONG).show();//해당목차눌렸을때

}

@Override

public void onNothingSelected(AdapterView<?> arg0) {

// TODO Auto-generated method stub

}

}

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

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:orientation="vertical" >

    <TextView

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:text="@string/hello" />

    <Spinner

        android:id="@+id/spinner"
