Check if music playing in android media player API
提问by Zahid Habib
I'm using this code below to play an audio file in android
我正在使用下面的代码在 android 中播放音频文件
MediaPlayer mediaPlayer = new MediaPlayer();
mediaPlayer.setDataSource("fileSourceHere");
mediaPlayer.prepare();
mediaPlayer.start();
I have a button on that program. When click on that button, it'll check if music playing. If music playing, it'll stop that. How can I check if music playing? I tried the code below but it didn't work
我在那个程序上有一个按钮。单击该按钮时，它会检查是否正在播放音乐。如果音乐播放，它会停止。如何检查音乐是否正在播放？我尝试了下面的代码，但没有用
if(mediaPlayer.isPlaying() == true){
mediaPlayer.pause();
}else{
mediaPlayer.start();
}

And if you want to know about your app music.
如果您想了解您的应用音乐。
Add Listener to listen
添加监听器进行监听
mediaPlayer.setOnPreparedListener(this);
mediaPlayer.setOnCompletionListener(this);
mediaPlayer.setOnErrorListener(this);
you can add a boolean variable to check isPlaying;
您可以添加一个布尔变量来检查 isPlaying；
boolean isPlaying= false; //false by default
and when you start mediaPlayerat the very moment set isPlaying=trueand you are good to go.
当你start mediaPlayer在那个时刻准备isPlaying=true好开始的时候。
