检查以校验是否在使用前已全部初始化( 不是无效)

if (upSound != null)
  upSound.start();

.....................................................................................................................................................

您可以初始化苍蝇上的声音, 以确保声音是空的, 反正它会被播放 。

  if (upSound == null)
     upSound = MediaPlayer.create(Directions.this, R.raw.up_sound);
  upSound.start();

Additionally, your textView En_description may also be null which could cause this crash as well. Make sure wherever you are retrieving En_description (using findViewById) it is completing successfully

不知道这是否是你的问题, 但你可能尝试在做 v. getId () 之前对 v. getId () 进行无效检查 。

if (v != null)
{
    // Do switch statement
}
