Cara Buat Aplikasi Android Spinner Adapter

Ini Adalah Source Code Untuk MainActivity.java

import android.app.Activity;

import android.os.Bundle;

import android.view.Menu;

import android.view.View;

import android.widget.AdapterView;

import android.widget.ArrayAdapter;

import android.widget.Spinner;

import android.widget.TextView;

import android.widget.Toast;

public class MainActivity extends Activity implements AdapterView.OnItemSelectedListener{

   

    String[] Prov = { "Sulut", "Sulsel", "Sulteng", "Sulbar","Sultra", "Gorontalo"};

   @Override

   public void onCreate(Bundle icicle) {

       super.onCreate(icicle);

       setContentView(R.layout.activity_main);

       selection = (TextView) findViewById(R.id.selection);

       Spinner spin = (Spinner) findViewById(R.id.spinner);

       spin.setOnItemSelectedListener(this);

       ArrayAdapter<String> aa = new ArrayAdapter<String>

       (this,android.R.layout.simple_spinner_item, Prov);

       aa.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

       spin.setAdapter(aa);

   }

   @Override

   public boolean onCreateOptionsMenu(Menu menu) {

       // Inflate the menu; this adds items to the action bar if it is present.

       getMenuInflater().inflate(R.menu.main, menu);

       return true;

   }

   public void onItemSelected(AdapterView<?> parent, View v, int position,   long id) {

        Toast.makeText(this, "Anda Memilih: " + Prov [position],Toast.LENGTH_LONG).show();

    }

    TextView selection;

    public void onNothingSelected(AdapterView<?> parent) {

       Toast.makeText(this, "Silahkan Pilih Prov", Toast.LENGTH_LONG).show();

   }

   

}

Next Kita Buatkan File activity_main.xml Ini Source Code Nya

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

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

  android:orientation="vertical"

  android:background="#8b8b8b"

  android:layout_width="fill_parent"

  android:layout_height="fill_parent">

  

    <TextView

        android:text="Provinsi Pulau Sulawesi"

        android:textStyle="bold"

        android:textSize="10pt"

        android:textColor="#2b2b2b"

        android:id="@+id/selection"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content" />

    <Spinner

        android:id="@+id/spinner"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:drawSelectorOnTop="true" />

  

</LinearLayout>

Dan Ini Adalah Running Hasil Akhir Dari Source Code Di Atas
