package com.example.onlinemusicplayer;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.widget.SeekBar;

public class MainActivity extends Activity {

页面布局

<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" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="在线音乐播放器" />

    <EditText
        android:id="@+id/editText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="在线音乐路径" />

    <SeekBar
        android:id="@+id/seekBar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="10dp" />

    <Button
        android:layout_width="match_parent"

        android:layout_gravity="bottom"
        android:onClick="play"
        android:text="开始播放" />

</LinearLayout>

附加

音频文件我之前是用的科大讯飞语义的音乐场景测试的，科大讯飞的语义场景是基于“酷音云”做的，“酷音云”提供了在线的mp3格式的彩铃音乐（版权问题，只能是这种形式）文件。

测试效果如下（测试之前先添加音乐场景）：
