Android 给贪吃蛇游戏加背景音乐

Android有个贪吃蛇的游戏，但是打开这个游戏非常枯燥，给加个背景音乐吧

1、增加一个类，这个类是继承Service的，如下。

package com.example.Android.snake;import Android.app.Service; import Android.content.Intent;import Android.media.MediaPlayer; import Android.os.IBinder;public class MusicServer extends Service { private MediaPlayer mediaPlayer; @Override public IBinder onBind(Intent intent) {// TODO Auto-generated method stubreturn null;}@Override public void onStart(Intent intent,int startId){super.onStart(intent, startId);if(mediaPlayer==null){ // R.raw.mmp是资源文件，MP3格式的 mediaPlayer = MediaPlayer.create(this, R.raw.mmp);mediaPlayer.setLooping(true);mediaPlayer.start();} }@Overridepublic void onDestroy() {// TODO Auto-generated method stubsuper.onDestroy();mediaPlayer.stop();}}

 

2、在AndroidManifest.xml中添加如下代码。

<service Android:name=".MusicServer"><intent-filter><action Android:name="com.angel.Android.MUSIC"/><category Android:name="android.intent.category.default" /></intent-filter></service>

 

3.在Snake.java加入以下代码

 

package com.example.Android.snake;import Android.app.Activity; import Android.os.Bundle;import Android.view.Window;import Android.widget.TextView;import Android.content.Intent;public class Snake extends Activity { private SnakeView mSnakeView; private Intent intent = new Intent("com.angel.Android.MUSIC");private static String ICICLE_KEY = "snake-view";/*** Called when Activity is first created. Turns off the title bar, sets up* the content views, and fires up the SnakeView.* */@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.snake_layout); //start background music startService(intent);mSnakeView = (SnakeView) findViewById(R.id.snake);mSnakeView.setTextView((TextView) findViewById(R.id.text));if (savedInstanceState == null) { // We were just launched -- set up a new gamemSnakeView.setMode(SnakeView.READY);} else {// We are being restoredBundle map = savedInstanceState.getBundle(ICICLE_KEY);if (map != null) {mSnakeView.restoreState(map);} else {mSnakeView.setMode(SnakeView.PAUSE);}}}@Override protected void onPause() {super.onPause();// Pause the game along with the activitymSnakeView.setMode(SnakeView.PAUSE); stopService(intent);}@Override public void onSaveInstanceState(Bundle outState) {//Store the game stateoutState.putBundle(ICICLE_KEY, mSnakeView.saveState());}}
