在我的应用程序中,我正在使用媒体播放器,我想在那里放置一个搜索栏。在我的代码中,歌曲正在播放,但搜索栏没有移动。以下是我的代码的一部分...
sv = (SurfaceView)findViewById(R.id.surfaceView1);
sv.postDelayed(runnable,200);
final Runnable runnable = new Runnable()
{
@Override
public void run()
{
if (mediaPlayer != null)
{
if (isPlaying)
{
try
{
int currentPosition = mediaPlayer.getCurrentPosition();
audioProgress.setProgress((int) ((currentPosition / (float) mediaPlayer.getDuration()) * 100f));
} catch (Exception e) {
e.printStackTrace();
}
sv.postDelayed(runnable, 150);
}
}
}
};
请有人帮我清除错误......

对您的代码进行以下更改:
sv = (SurfaceView)findViewById(R.id.surfaceView1);
audioProgress.setMax(mediaPlayer.getDuration()); // this is one change
sv.postDelayed(runnable,200);
final Runnable runnable = new Runnable()
{
@Override
public void run()
{
if (mediaPlayer != null)
{
if (isPlaying)
{
try
{
int currentPosition = mediaPlayer.getCurrentPosition();
// the other change:
audioProgress.setProgress(currentPosition);
} catch (Exception e) {
e.printStackTrace();
}
sv.postDelayed(runnable, 150);
}
}
}
};
