Android声音未在初始屏幕中播放

显示初始屏幕时，我在播放声音时遇到麻烦.我已经在"res"目录下创建了"raw"目录，并将droid.mp3文件放在那里(大约150Kb).

Im having troubles with playing sound while the splash screen shows. Ive created the "raw" directory under "res" directory and put the droid.mp3 file there (around 150Kb).

这是负责启动屏幕的外观和声音的java文件的代码:

This is the code of the java file responsible for the appearance and sound of the splash screen:

import android.app.Activity; import android.content.Intent; import android.media.MediaPlayer; import android.os.Bundle; public class SplashActivity extends Activity { public MediaPlayer splashSound; protected void onCreate(Bundle splashBundle) { super.onCreate(splashBundle); setContentView(R.layout.splash); splashSound = MediaPlayer.create(SplashActivity.this, R.raw.droid); Thread t1 = new Thread() { public void run() { try { sleep(5000); } catch (InterruptedException IE) { IE.printStackTrace(); } finally { Intent mainActivityIntent=new Intent("com.example.stamapp.MAINACTIVITY"); startActivity(mainActivityIntent); } } }; t1.start(); } @Override protected void onPause() { super.onPause(); splashSound.release(); finish(); } }

非常感谢您的帮助.

推荐答案

而不是线程尝试使用 Handler.postDelayed 为:

instead of Thread try is using Handler.postDelayed as:

Handler handler; protected void onCreate(Bundle splashBundle) { super.onCreate(splashBundle); setContentView(R.layout.splash); handler = new Handler(); splashSound = MediaPlayer.create(SplashActivity.this, R.raw.droid); splashSound.start(); //<<<play sound on Splash Screen handler.postDelayed(runnable, 5000); } private Runnable runnable = new Runnable() { @Override public void run() { //start your Next Activity here } };

第二种方法是将 MediaPlayer.setOnCompletionListener 添加到MediaPlayer实例，该实例在媒体源播放完成时调用而没有将5000 Delay设置为:

and second way is add MediaPlayer.setOnCompletionListener to MediaPlayer instance which invoke when playback of a media source has completed without putting 5000 Delay as :

protected void onCreate(Bundle splashBundle) { super.onCreate(splashBundle); setContentView(R.layout.splash); splashSound = MediaPlayer.create(SplashActivity.this, R.raw.droid); splashSound.setOnCompletionListener(new MediaPlayer.OnCompletionListener() { @Override public void onCompletion(MediaPlayer splashSound) { splashSound.stop(); splashSound.release(); //start your Next Activity here } }); splashSound.start(); //<<<play sound on Splash Screen }
