英文:
mediaPlayer.release() crashes my app java
问题
我有一个项目，在自定义的数组适配器中添加了一个 MediaPlayer，我让它从数组列表中获取音频文件的资源 ID。问题是，我希望在音频播放完成后释放媒体播放器，但每次我尝试在 OnCompletion 中添加释放操作，并且在媒体播放器播放声音时尝试按下视图，应用程序就会崩溃。我在网上搜索到一段代码，但它给了我一个错误，我找不到这种崩溃的实际原因。以下是点击监听器和媒体播放器的代码：
final MediaPlayer mediaPlayer = MediaPlayer.create(getContext(), currentWord.getVoiceResourceID());
// 等待用户通过单击列表项来播放声音。
View.OnClickListener listener = new View.OnClickListener() {
@Override
public void onClick(View v) {
// 将 getVoiceResourceID() 的返回值存储到 mVoice 中。
// 我认为这一行可以忽略，所以我们在创建媒体播放器时调用该方法。
// 创建我们的媒体播放器并将轨道放入其中。
mediaPlayer.selectTrack(currentWord.getVoiceResourceID());
mediaPlayer.start();
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
mediaPlayer.release();
}
});
}
};
希望我能解决这个问题。
英文:
I have a project where I added a MediaPlayer in a custom Array Adapter and I make it take the Resource ID of the audio file from the Array List the problem is that I want to release the media player after the audio completes but every time I try to add release in OnCompletion and try to press a view while the media player plays a sound the app crashes .. I searched online and found a code but it gives me an error and I can't find the actual reason for such a crash.
that's the code for the on Click Listener and the Media player:
final MediaPlayer mediaPlayer = MediaPlayer.create(getContext(), currentWord.getVoiceResourceID());
// Wait for user's input by his click on the list's item to play the sound.
View.OnClickListener listener = new View.OnClickListener() {
@Override
public void onClick(View v) {
// Storing the return value of getVoiceResourceID() into mVoice.
// I think this line can be ignored so we call the method inside the creation of the Media Player.
// Creating our media player and put our track on it.
mediaPlayer.selectTrack(currentWord.getVoiceResourceID());
mediaPlayer.start();
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
mediaPlayer.release();
}
});
}
};
I hope I could fix that problem.
