How to implement Android voice playback function

Implementation method: 1. Use MediaPlayer to implement: add permissions in the AndroidManifest.xml file, then create the MediaPlayer object and set the data source in the Activity code, and finally call the prepare() and start() methods to play ; 2. Use SoundPool implementation: Create a SoundPool object in the Activity code and set the maximum number of concurrent streams, then load the audio resources and set a listener for completion of playback.

On the Android platform, you can use MediaPlayer or SoundPool to implement the voice playback function.

1. Use MediaPlayer to implement the voice playback function:

First add the following permissions in the AndroidManifest.xml file:

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

Then create the MediaPlayer object and set it in the Activity code Data source, and finally call the prepare() and start() methods for playback:

MediaPlayer mediaPlayer = new MediaPlayer();
try {
    mediaPlayer.setDataSource(path); // 设置音频文件路径
    mediaPlayer.prepare(); // 准备音频播放器
    mediaPlayer.start(); // 开始播放
} catch (IOException e) {
    e.printStackTrace();
}

2. Use SoundPool to implement the voice playback function:

First create a SoundPool object in the Activity code and set the maximum The number of concurrent streams, then load the audio resource and set the listener for playback completion:

SoundPool soundPool = new SoundPool.Builder().setMaxStreams(1).build();
int soundId = soundPool.load(context, R.raw.audio_file, 1); // 加载音频资源
soundPool.setOnLoadCompleteListener(new SoundPool.OnLoadCompleteListener() {
    @Override
    public void onLoadComplete(SoundPool soundPool, int sampleId, int status) {
        soundPool.play(soundId, 1, 1, 1, 0, 1); // 播放音频
    }
});

The above are two commonly used methods to implement the voice playback function. You can choose the appropriate method for implementation according to specific needs.
