问题
我遇到了关于mediaPlayer的问题，我想通过按钮的点击来更改（文件）mediaplayer=mediaplayer.create(r.folder."file")，并且在按下另一个按钮时再次更改它。
我有几个按钮，我想为每个事件分配不同的声音进行播放。

使用switch语句，根据按钮的ID创建具有不同源的媒体文件。

首先，在活动中将MediaPlayer变量设置为全局，并在onCreate方法触发时进行赋值，如下所示：
private MediaPlayer mediaPlayer;
@Override
public void onCreate() {
super.onCreate();
// 分配媒体播放器
mediaPlayer = new MediaPlayer();
}
假设您已经将5个按钮分配为{ button1 button2 button3 button4 和 button5 }，请为它们添加点击监听器，如下所示：
button1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// 更改音乐
}
});
现在，我们要做的是，每次单击按钮时，都要重置现有的MediaPlayer，然后将新文件分配给它，然后播放该文件。
因此，在每个监听器的onClick事件中，您需要运行以下代码：
mediaPlayer.reset();
try {
mediaPlayer.setDataSource("/storage/emulated/0....路径到您的文件");
mediaPlayer.prepare();
mediaPlayer.start();
}
catch (Exception ex){
// 发生异常
};
每个按钮的onClick监听器现在应该如下所示：
// 按钮1
button1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// 更改音乐
mediaPlayer.reset();
try {
mediaPlayer.setDataSource("/storage/emulated/0....路径到您的文件");
mediaPlayer.prepare();
mediaPlayer.start();
}
catch (Exception ex){
// 发生异常
};
}
});
// 按钮2
button2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// 更改音乐
mediaPlayer.reset();
try {
mediaPlayer.setDataSource("/storage/emulated/0....路径到您的文件");
mediaPlayer.prepare();
mediaPlayer.start();
}
catch (Exception ex){
// 发生异常
};
}
});
Button 3、4和5的处理方式类似。
英文:
Firstly make the MediaPlayer variable global in the activity, and assign it when the onCreate methord fires in your Activity like this
Private MediaPlayer mediaPlayer ;
@Override
public void onCreate() {
super.onCreate();
//assign the media player
mediaPlayer = new MediaPlayer();
}
Assuming you have your 5 buttons assigned as { button1 button2 button3 button4 and button5 } , add onclick listeners to all of them like this
button1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
//change the music
}
});
Now what we want to do is that, everytime you click a button we want to reset the existing MediaPlayer and then assign a new file to it, and then play that file.
So in the onClick event of each listener you need to run the code
mediaPlayer.reset();
try {
mediaPlayer.setDataSource("/storage/emulated/0....path to yor file");
mediaPlayer.prepare();
mediaPlayer.start();
}
catch (Exception ex){
//we have an exception
};
The onClick listeners for each button should now look like this
//button1
button1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
//change the music
mediaPlayer.reset();
try {
mediaPlayer.setDataSource("/storage/emulated/0....path to yor file");
mediaPlayer.prepare();
mediaPlayer.start();
}
catch (Exception ex){
//we have an exception
};
//button 2
button2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
//change the music
mediaPlayer.reset();
try {
mediaPlayer.setDataSource("/storage/emulated/0....path to yor file");
mediaPlayer.prepare();
mediaPlayer.start();
}
catch (Exception ex){
//we have an exception
};
}
});
}
});
//Button 3 , 4 and 5
