Spinner spinner = (Spinner) findViewById(R.id.sMonth); 
spinner.setOnItemSelectedListener(this); 
ArrayList categories=new ArrayList(); 
categories.add("Month"); 
categories.add("Jan"); 
categories.add("Feb"); 
categories.add("Mar");

dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
spinner.setAdapter(dataAdapter);

string.xmlを

<?xml version="1.0" encoding="utf-8"?> 
<resources> 
    <string name="app_name">AndroidSpinnerExample</string> 
    <string name="spinner_title">Select Category</string> 
</resources> 

XML

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:padding="10dip" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"> 

    <!-- Text Label --> 
    <TextView 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:layout_marginTop="10dip" 
     android:text="Category:" 
     android:layout_marginBottom="5dp" 
    /> 

    <!-- Spinner Element --> 
    <Spinner 
     android:id="@+id/spinner" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:prompt="@string/spinner_title" 
    /> 
</LinearLayout> 

JAVAコード

import java.util.ArrayList; 
import java.util.List; 

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; 
import android.widget.AdapterView.OnItemSelectedListener; 

public class AndroidSpinnerExampleActivity extends Activity implements OnItemSelectedListener{ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     // Spinner element 
     Spinner spinner = (Spinner) findViewById(R.id.spinner); 

     // Spinner click listener 
     spinner.setOnItemSelectedListener(this); 

     // Spinner Drop down elements 
     List<String> categories = new ArrayList<String>(); 
     categories.add("Automobile"); 
     categories.add("Business Services"); 
     categories.add("Computers"); 
     categories.add("Education"); 
     categories.add("Personal"); 
     categories.add("Travel"); 

     // Creating adapter for spinner 
     ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, categories); 

     // Drop down layout style - list view with radio button 
     dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 

     // attaching data adapter to spinner 
     spinner.setAdapter(dataAdapter); 
    } 

    @Override 
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { 
     // On selecting a spinner item 
     String item = parent.getItemAtPosition(position).toString(); 

     // Showing selected spinner item 
     Toast.makeText(parent.getContext(), "Selected: " + item, Toast.LENGTH_LONG).show(); 

    } 

    public void onNothingSelected(AdapterView<?> arg0) { 
     // TODO Auto-generated method stub 

    } 

} 

OUTPUT

Answer 2

は、あなただけのようなスピナーアダプタのドロップダウンでAndroidレイアウトselect_dialog_singlechoiceを追加する必要があります......

adapter.setDropDownViewResource(android.R.layout.select_dialog_singlechoice);
