我在对话框中使用搜索栏媒体播放器，但当我点击它时，搜索栏不起作用
我正在制作录音机应用程序并使用搜索来播放音频文件 . 当我点击搜索栏时，它向前移动，但在1秒后它将被设置回到之前的位置 .

你在哪里称media.seekTo（位置）？据我所知，你没有在seekbarchangelistener上调用它 .
因为你总是设置相对于你的歌曲进度的搜索栏位置..它将总是回到以前的状态..
解决方案：在你的seekbarchangelistener中..使用onSeekbarchanged并使用（媒体播放器）.seekTo（position）
I use this code and issue resolved
