Question

有一个播放按钮（声音评论），当我点击它播放时，但是当我多次击中时，它会成倍增加。我想用其他主题代码来阻止这个，没有任何帮助，不知道吗？

img_scream1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
                if(mediaControl.isPlaying()==true){
                    mediaControl.pause();
                }
            else
                {
                    mediaControl = MediaPlayer.create(java_sounds_scary.this, R.raw.hooray);
                    mediaControl.start();
                }


        }
    });

将您的代码更改为以下内容：

    running py2exe
    Traceback (most recent call last):
      File "setup.py", line 14, in <module>
        }, zipfile=None, console=['main.py'])

每次都不要创建mediaControl实例（使歌曲从开始加载）。相反，您可以将mediaControl初始化为null，并在null

时创建它的实例

    mediaControl =null;
    img_scream1.setOnClickListener(new View.OnClickListener(){
        @Override
            public void onClick (View view){
                if (mediaControl == null) {
                    mediaControl = MediaPlayer.create(java_sounds_scary.this, R.raw.hooray);
                }
                if (mediaControl.isPlaying() == true) {
                    mediaControl.pause();
                } else {
                    mediaControl.start();
                }
        }
    });

如何让MediaPlayer等待其他点击请求？
