1、新建xml文件定义各个属性：
<?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="match_parent"
android:background="@drawable/skin_bg"
android:orientation="vertical" >
<TextView
android:id="@+id/txttile"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginTop="40dp" />
<TextView
android:id="@+id/txtdangtime"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="6dp"
android:layout_marginTop="385dp"
android:text="1:30"
android:textSize="18dp" />
<TextView
android:id="@+id/txtzongtime"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="270dp"
android:layout_marginTop="385dp"
android:text="3:30"
android:textSize="18dp" />
<SeekBar
android:id="@+id/seekbar"
android:layout_width="220dp"
android:layout_height="wrap_content"
android:layout_marginLeft="45dp"
android:layout_marginTop="380dp"
android:background="@android:color/holo_red_dark" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" >
<ImageButton
android:id="@+id/buttonplayer"
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_marginBottom="100dp"
android:layout_marginLeft="140dp"
android:layout_marginTop="420dp"
android:src="@drawable/zanting" />
<ImageButton
android:id="@+id/buttonnext"
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_marginLeft="20dp"
android:layout_marginTop="420dp"
android:layout_toRightOf="@id/buttonplayer"
android:src="@drawable/nextsong" />
<ImageButton
android:id="@+id/buttonshang"
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_marginLeft="90dp"
android:layout_marginTop="420dp"
android:background="@drawable/shangsong" />
</RelativeLayout>
</RelativeLayout>-----------------------------------------------------------------------------分割线-----------------------------------------------------------------------------------

MediaPlayer(mList.get(mCurrentPosition));
break;
case R.id.buttonplayer:
// 暂停/播放
if (playing == true) {

mCurrentPosition = mList.size() - 1;
}
mMediaPlayer.release();
mMediaPlayer = null;
MediaPlayer(mList.get(mCurrentPosition));
break;
}
}
}以上播放器只能实现播放，暂停、上一曲、下一曲、播放结束自动播放下一曲、拖动进度条、歌曲当前时间总时间。
