Android网络收音机项目

發布時間：2023/12/20 Android 41 豆豆

生活随笔收集整理的這篇文章主要介紹了 Android网络收音机项目小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

?最近喜歡聽廣播，但是搜索了一下，苦于網上沒有android的網絡收音機項目的例子，于是自己動手實現了Android網絡收音機項目。?
??? 前言，由于很多網絡廣播使用的協議是mms，來自微軟，但是android并不支持這種流媒體協議，我的解決辦法是使用Vitamio插件+Vitamio庫的方式解決。這樣在安裝app本身的apk同時還要安裝對應你手機的Vitamio插件，這個插件是老外開發的還免費，支持很多媒體格式，安上一個也挺好的，大概3M多。有一點要注意的是這個插件跟硬件有關，所以...所以如果你可以一個一個的試，看哪個適應你的手機硬件，這個插件有4個版本：?
?????? ARMv6: for some low end devices (Market, VOV)?
?????? VFP: for some low end devices with VFP support (Market, VOV)?
?????? ARMv7: for ARMv7 devices without NEON support, such as Tegra 2 powered? devices(Market, VOV)?
?????? NEON: for ARMv7 devices with NEON support (Market, VOV)?
具體可以上 http://vov.io/vitamio/ 看一下，我的爛手機是VFP這個版本的。?
??? 開始前的準備，你最好在上面的官網上下載一份API看看：Vitamio-SDK.7z。SDK里面還有vitamio.jar這個jar文件，里面有流媒體的控制類。OK廢話不多說，上代碼(導jar包相信大家都了然，這里不作介紹)：?

AndroidManifest文件?
Java代碼??

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

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

??????package="com.netradiodemo"??

??????android:versionCode="1"??

??????android:versionName="1.0">??

????<uses-sdk?android:minSdkVersion="10"?/>??

????<uses-permission?android:name="android.permission.INTERNET"></uses-permission>??

????<application?android:icon="@drawable/icon"?android:label="@string/app_name"??

?????android:theme="@android:style/Theme.Black">??

????????<activity?android:name=".NetRadioDemoActivity"??

??????????????????android:label="@string/app_name">??

????????????<intent-filter>??

????????????????<action?android:name="android.intent.action.MAIN"?/>??

????????????????<category?android:name="android.intent.category.LAUNCHER"?/>??

????????????</intent-filter>??

????????</activity>??

????<activity?android:name=".compnents.PlayerActivity"></activity>??

????</application>??

</manifest>??

主頁面布局文件main未修改，播放頁面布局文件如下play_page?
Java代碼??

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

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

????android:orientation="vertical"??

????android:layout_width="fill_parent"??

????android:layout_height="fill_parent"??

????>??

<Button????

????android:id="@+id/btn_start"??

????android:layout_gravity="center_horizontal"??

????android:layout_width="match_parent"??

????android:layout_height="wrap_content"??

????android:text="聽貓撲"??

????android:textSize="30sp"??

????android:onClick="doStart"??

????/>??

????<Button????

????android:id="@+id/btn_stop"??

????android:layout_gravity="center_horizontal"??

????android:layout_width="match_parent"??

????android:layout_height="wrap_content"??

????android:text="不聽貓撲"??

????android:textSize="30sp"??

????android:onClick="doStop"??

????/>??

</LinearLayout>??

第一個activity代碼，主要負責檢查插件NetRadioDemoActivity?
Java代碼??

package?com.netradiodemo;??

import?io.vov.vitamio.VitamioInstaller;??

import?io.vov.vitamio.VitamioInstaller.VitamioNotCompatibleException;??

import?io.vov.vitamio.VitamioInstaller.VitamioNotFoundException;??

import?android.app.Activity;??

import?android.content.Intent;??

import?android.os.Bundle;??

import?android.util.Log;??

import?android.view.View;??

import?android.view.View.OnClickListener;??

import?android.widget.Button;??

import?android.widget.LinearLayout.LayoutParams;??

import?android.widget.TextView;??

import?android.widget.Toast;??

import?com.netradiodemo.compnents.PlayerActivity;??

public?class?NetRadioDemoActivity?extends?Activity?{??

????Intent?intent?;??

????@Override??

????public?void?onCreate(Bundle?savedInstanceState)?{??

????????super.onCreate(savedInstanceState);??

????????setContentView(R.layout.main);??

????????intent?=?new?Intent(this,?PlayerActivity.class);??

????????TextView?tvCheck?=?new?TextView(this);??

????????tvCheck.setText("使用前請檢查是否安裝了Vitamio插件:");??

????????this.addContentView(tvCheck,?new?LayoutParams(LayoutParams.MATCH_PARENT,?LayoutParams.WRAP_CONTENT));??

??????????

????????Button?btnCheck?=?new?Button(this);??

????????btnCheck.setText("檢查");??

????????btnCheck.setOnClickListener(new?OnClickListener()?{??

????????????@Override??

????????????public?void?onClick(View?arg0)?{??

????????????????try?{??

????????????????????String?isInstallerString?=?VitamioInstaller??

????????????????????????????.checkVitamioInstallation(NetRadioDemoActivity.this);//檢查插件是否安裝成功,這里是一個費時操作,應該啟新線程處理,作為一個demo我就不做了??

????????????????????Log.i("tag",isInstallerString);?//插件安裝成功后,Log中顯示插件名稱??

????????????????????if(isInstallerString!=null){??

????????????????????????Toast.makeText(NetRadioDemoActivity.this,?"已安裝正確版本Vitamio!",?Toast.LENGTH_LONG).show();???

????????????????????????startActivity(intent);//開啟收聽界面??

????????????????????}else{??

????????????????????????Toast.makeText(NetRadioDemoActivity.this,?"沒有匹配的Vitamio!",?Toast.LENGTH_LONG).show();??

????????????????????????finish();//沒有插件安裝失敗,則結束程序??

????????????????????}??

????????????????}?catch?(VitamioNotCompatibleException?e)?{??

????????????????????e.printStackTrace();??

????????????????}?catch?(VitamioNotFoundException?e)?{??

????????????????????e.printStackTrace();??

????????????????}??

????????????}??

????????});??

????????this.addContentView(btnCheck,?new?LayoutParams(LayoutParams.WRAP_CONTENT,?LayoutParams.WRAP_CONTENT));??

????}??

}??

第二個activity，主要負責播放PlayerActivity?
Java代碼??

package?com.netradiodemo.compnents;??

import?android.view.View;??

import?android.widget.LinearLayout.LayoutParams;??

import?com.netradiodemo.R;??

public?class?PlayerActivity?extends?Activity?{??

????MediaPlayer?mPlayer;??

????@Override??

????protected?void?onCreate(Bundle?savedInstanceState)?{??

????????setContentView(R.layout.play_page);??

????????MediaController?controller?=?new?MediaController(this);//創建控制對象??

????????this.addContentView(controller,?new?LayoutParams(LayoutParams.WRAP_CONTENT,?LayoutParams.WRAP_CONTENT));??

????????String?path?=?"mms://ting.mop.com/mopradio";//貓撲電臺地址,這里可以添加自己的喜歡的電臺地址,mms協議的??

????????try?{??

????????????mPlayer?=?new?MediaPlayer(this);//播放流媒體的對象??

????????????mPlayer.setDataSource(path);//設置流媒體的數據源??
