Android Studio: Membuat aplikasi pemutar music

1. Buatlah project baru dengan nama PlayMusic dengan tampilan akhir seperti pada gambar di bawah.



2. Ganti file activity_main.xml dengan skrip berikut:

xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:id="@+id/activity_main"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:background="@drawable/aaa"    tools:context=".MainActivity">

    <Button        android:id="@+id/btnPlay"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_above="@+id/btnPause"        android:layout_alignParentLeft="true"        android:layout_alignParentStart="true"        android:drawableLeft="@android:drawable/ic_media_play"        android:onClick="playSong"        android:text="Play" />

    <Button        android:id="@+id/btnPause"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_above="@+id/btnStop"        android:layout_alignParentLeft="true"        android:layout_alignParentStart="true"        android:drawableLeft="@android:drawable/ic_media_pause"        android:onClick="pauseSong"        android:text="Pause" />

    <Button        android:id="@+id/btnStop"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_alignParentBottom="true"        android:layout_alignParentLeft="true"        android:layout_alignParentStart="true"        android:drawableLeft="@android:drawable/ic_lock_power_off"        android:onClick="stopSong"        android:text="Stop" />

    <TextView        android:id="@+id/textView"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_alignParentTop="true"        android:layout_centerHorizontal="true"        android:layout_marginTop="16dp"        android:text="Audio Player"        android:textAlignment="center"        android:textColor="@android:color/background_light"        android:textSize="24sp" />

    <TextView        android:id="@+id/textView2"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_above="@+id/btnPlay"        android:layout_centerHorizontal="true"        android:layout_marginBottom="140dp"        android:text="DANIE"        android:textColor="@android:color/background_light"        android:textSize="70sp" />

</RelativeLayout>

3. Ganti file MainActivity.java dengan skrip berikut :

package com.example.hp.audioplayer;

import android.media.MediaPlayer;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;

public class MainActivity extends AppCompatActivity {

    MediaPlayer mp;

    @Override    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mp=MediaPlayer.create(this, R.raw.adele);
    }

    public void playSong(View v){
        mp.start();
    }

    public void pauseSong(View v) {
        mp.pause();
    }

    public void stopSong(View v) {
        mp.stop();
        // mp=MediaPlayer.create(this, R.raw.adele);        finish();
        moveTaskToBack(true);
    }
}

4. Jalankan aplikasi tersebut.
