Radio Button dengan MediaPlayer

Pada kesempatan tugas UTS kali ini saya akan membuat aplikasi android sederhana yaitu, Radio Button dengan Media Player.

Langsung saja untuk Step 1,

Buat Project baru di Eclipse IDE, File => Android Application Project. Kemudia berikan nama Activity sebagai MainActivity.

Step 2,

Buka Folder res => layout => main_activity.xml

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

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

    android:layout_width="match_parent"

    android:layout_height="fill_parent"

    android:orientation="vertical" >

   

    <RadioGroup

        android:id="@+id/music"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content" >

       

        <TextView

            android:id="@+id/pop"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:layout_marginLeft="10dp"

            android:layout_marginTop="10dp"

            android:text="Pop"

            android:textAppearance="?android:attr/textAppearanceLarge" />

       

        <RadioButton

            android:id="@+id/kangen"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:layout_marginLeft="35dp"

            android:text="Dewa 19 - Kangen" />

       

        <RadioButton

            android:id="@+id/ibu"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:layout_marginLeft="35dp"

            android:text="Iwan Fals - Ibu" />

       

        <RadioButton

            android:id="@+id/dealova"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:layout_marginLeft="35dp"

            android:text="Once - Dealova"/>

       

        <TextView

            android:id="@+id/accoustic"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:layout_marginLeft="10dp"

            android:layout_marginTop="10dp"

            android:text="Accoustic"

            android:textAppearance="?android:attr/textAppearanceLarge" />

       

        <RadioButton

            android:id="@+id/imyours"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:layout_marginLeft="35dp"

            android:text="Sabrina - I\'m Yours" />

       

        <RadioButton

            android:id="@+id/badday"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:layout_marginLeft="35dp"

            android:text="Sabrina - Bad Day" />

       

        <RadioButton

            android:id="@+id/youandme"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:layout_marginLeft="35dp"

            android:text="Lifehouse - You and Me"/>

    </RadioGroup>

    <Button

        android:id="@+id/stop"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:layout_alignParentBottom="true"

        android:text="Stop" />

   

</RelativeLayout>

 

Step 3,

Buka Folder src => (package name) => MainActivity.java

package su.barman.radiobuttonmusic;

import android.app.Activity;

import android.os.Bundle;

public class MainActivity extends Activity {

       @Override

       public void onCreate(Bundle savedInstanceState) {

              super.onCreate(savedInstanceState);

              setContentView(R.layout.main_activity);

             

             

       }      

}

Step 4,

Coba jalankan aplikasi tersebut, berikut tampilannya :

Step  5,

Buat folder baru di dalam folder res dan berikan nama raw, folder raw adalah tempat penyimpanan musik

Step 6, Selesai

Buka kembali file MainActivity.java

package su.barman.radiobuttonmusic;

import android.app.Activity;

import android.media.MediaPlayer;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.RadioButton;

import android.widget.RadioGroup;

import android.widget.Toast;

public class MainActivity extends Activity {

       public MediaPlayer mp;

      

       public RadioGroup musicid;

      

       public int resId;

       public String title;

      

       public Button stop;

      

       public RadioButton kangenid, ibuid, dealovaid, imyoursid, baddayid, youandmeid;

      

       @Override

       public void onCreate(Bundle savedInstanceState) {

              super.onCreate(savedInstanceState);

              setContentView(R.layout.main_activity);

             

              kangenid      = (RadioButton) findViewById(R.id.kangen);

              ibuid         = (RadioButton) findViewById(R.id.ibu);

              dealovaid     = (RadioButton) findViewById(R.id.dealova);

              imyoursid     = (RadioButton) findViewById(R.id.imyours);

              baddayid      = (RadioButton) findViewById(R.id.badday);

              youandmeid    = (RadioButton) findViewById(R.id.youandme);

             

              musicid       = (RadioGroup) findViewById(R.id.music);

                          

              stop          = (Button) findViewById(R.id.stop);

             

              musicid.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {

                     @Override

                     public void onCheckedChanged(RadioGroup group, int checkedId) {

                           switch(checkedId) {

                                  case R.id.kangen:

                                         resId = R.raw.kangen;

                                         title = "Dewa 19 - Kangen";

                                  break;

                                  case R.id.ibu:

                                         resId = R.raw.ibu;

                                         title = "Iwan Fals - Ibu";

                                  break;

                                  case R.id.dealova:

                                         resId = R.raw.dealova;

                                         title = "Once - Dealova";                                    

                                  break;

                                  case R.id.imyours:

                                         resId = R.raw.imyours;

                                         title = "Sabrina - I\'m Yours";

                                  break;

                                  case R.id.badday:

                                         resId = R.raw.badday;

                                         title = "Sabrina - Bad Day";

                                  break;

                                  case R.id.youandme:

                                         resId = R.raw.youandme;

                                         title = "Lifehouse - You and Me";

                                  break;

                           }

                          

                           if(mp != null) {

                                  mp.release();

                           }

                          

                           mp = MediaPlayer.create(getApplicationContext(), resId);

                           mp.start();

                           Toast.makeText(getApplicationContext(), "Now "+title, Toast.LENGTH_SHORT);

                     }

              });

             

              stop.setOnClickListener(new OnClickListener(){

                     @Override

                     public void onClick(View v) {

                           if(mp != null) {

                                  if(mp.isPlaying()) {

                                         mp.stop();

                                         mp = null;

                                  }

                           }

                           Toast.makeText(getApplicationContext(), "Stop", Toast.LENGTH_SHORT);

                           kangenid.setChecked(false);

                           ibuid.setChecked(false);

                           dealovaid.setChecked(false);

                           imyoursid.setChecked(false);

                           baddayid.setChecked(false);

                           youandmeid.setChecked(false);

                     }

                    

              });

       }
