Android音频播放器

你的代码很难理解。。。 建议您遵循WarrenFaith的建议： 无论如何，根据你的问题，我已经理解了以下几点 搜索杆不光滑。 使用音频播放器的UI小部件很快会导致崩溃。 1。将Progressbar增加0.5而不是1。这将平滑进度条 两个人。我想你需要把垃圾堆放在这里。。。所以我们可以试着找出真正的根本原因。。。但不要把整个logcat都扔了
干杯 2愿望：1。改进你的问题，尝试使用点、逗号和2是很难理解的。请将粘贴的代码减少到您尝试更新seekbarin seekbar的部分我发现只有一种设置进度的方法，即setprogress，它只取整数值，那么我如何设置浮点值，我在我的计时器中设置seekabr的增量我认为它以1s.Sudeep的延迟执行，以使进度条平滑，我建议您将进度条的最大大小设置为非常高的范围。。。例如，如果您将进度条设置为1。。100范围，而不是使用100作为最大值，在适当位置使用1000。。这将平滑效果。通过将进度条增加。。。这只是一个建议。。干杯
