Android Media Player Tutorial

Sebelum memulai tutorial ini, buat folder terlebih dahulu folder raw di dalam folder res. copy lagu (pada contoh kali ini adalah song1.mp3) ke folder raw yang telah dibuat di dalam folder res

Berikut adalah activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <TextView
        android:id="@+id/tv_status"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:text="" />

    <SeekBar
        android:id="@+id/sb_status"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal" >

        <ImageButton
            android:id="@+id/btn_play"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@+id/seek_bar"
android:src="@android:drawable/ic_media_play" />

        <ImageButton
            android:id="@+id/btn_stop"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
android:src="@android:drawable/ic_dialog_alert" />

        <ImageButton
            android:id="@+id/btn_pause"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
android:src="@android:drawable/ic_media_pause" />
    </LinearLayout>

</LinearLayout>
