? ? ? ? 前些天在嘗試自己寫一個(gè)Android小游戲——flybird

? ? ? ? 基本功能實(shí)現(xiàn)了，就想添加聲音，然后上網(wǎng)查了查，大多是一樣，可是用到我這，有些卻不可以用，所以我還用了兩種方法。

? ? ? ? 下面談?wù)勥@兩種方法。

? ? ? ? 方法一：這是使用Java中的多線程，另外new出一個(gè)類，用類來(lái)啟動(dòng)音樂(lè)。

? ? ? ? ? ? ? ? ? ? ?這個(gè)方法，就像當(dāng)初寫java的小游戲一樣，不過(guò)是在電腦上運(yùn)行的，可以控制每一個(gè)動(dòng)作，比如你的觸碰動(dòng)作，但是，在我這個(gè)游戲中，我需要的不是一點(diǎn)的音樂(lè)，雖 ? ? ? ? ? ? ? 然后期會(huì)用到，而是一開(kāi)始就有的。

? ? ? ? ? ? ? ? ? ? ?不過(guò)，用這個(gè)方法，沒(méi)用service，就是開(kāi)起來(lái)的時(shí)候，會(huì)很卡，而且會(huì)閃退。

???????playSound(R.raw.boung);??

???}??

}??

? ? ? ? ? ? 然后，在需要的地方new出類，在調(diào)用方法。 ? ? ? ?

方法二：

? ? ? ? ? ? ?這種方法是利用android中的service來(lái)開(kāi)啟，也就是進(jìn)去的時(shí)候就播放出，退出就停止。

? ? ? ? ? ? ?首先，在AndroidManifest中的application節(jié)點(diǎn)下添加：

[java] view plaincopy

<activity??

????????????android:name=".MainActivity"??

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

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

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

??

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

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

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

? ? ? ? ? ? 然后，再在項(xiàng)目中new出一個(gè)類，MusicServer： [java] view plaincopy

package?com.example.flybird_anla;??

??

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?stub??

????????return?null;??

????}??

??

????@Override??

????public?void?onStart(Intent?intent,?int?startId)?{??

????????super.onStart(intent,?startId);??

??

????????if?(mediaPlayer?==?null)?{??

??

????????????//?R.raw.mmp是資源文件，MP3格式的??

????????????mediaPlayer?=?MediaPlayer.create(this,?R.raw.paopao);??

????????????mediaPlayer.setLooping(true);??

????????????mediaPlayer.start();??

??

????????}??

????}??

??

????@Override??

????public?void?onDestroy()?{??

????????//?TODO?Auto-generated?method?stub??

????????super.onDestroy();??

????????mediaPlayer.stop();??

????}??

}??

最后，在在activity中，寫兩個(gè)函數(shù)： [java] view plaincopy

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

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

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

????????startService(intent);??

????????manu();??

????}??

??????

????protected?void?onStop(){??

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

????????stopService(intent);??

????????super.onStop();??

??????????

????}??

? ? ? ? ?然后，就ok了。
