java - Android Studio音板: How to start a loop with a mediaplayer button?

Question

我正在尝试使用开关在每个按钮播放声音时打开或关闭循环。当开关切换时，我希望在此之后按下的任何按钮都循环播放，直到开关关闭。

我有大约 30 个按钮，它们都有自己的 setOnClickListener，原始文件夹中有一个 mp3。最初，我使用 soundPool 但它停止工作，所以我切换到 MediaPlayer，但我没有取得任何真正的成功。

我最新的更改是使用 Try and Catch 而不是 if，但我不知道它是否真的有帮助。

public class MainActivity extends Activity {

public static MediaPlayer mp;
