你能帮我解决这个问题吗?我有一个从url流式传输的搜索栏,我想在textView中显示mediaTimeyer的currentTime,那么如何更新textview以每秒获取当前时间
new Thread(new Runnable()
{
public void run()
{
while(mediaPlayer!=null )
{
seekprogress.setProgress(mediaPlayer.getCurrentPosition());
Message msg=new Message();
int millis = mediaPlayer.getCurrentPosition();
msg.obj=millis/1000;
try {
Thread.sleep(5000);
}
catch (InterruptedException e) {
e.printStackTrace();
}
seekprogress.setProgress(millis);
}
}
}).start();

使用AsyncTask:

您可以在onProgressUpdate期间更新TextView!

使用像@thiagolr这样的AsyncTask的一些示例代码
Timer seekBarTimer = new Timer();
TimerTask seekbarTimerTask = new TimerTask() {
@Override
public void run() {
runOnUiThread(new Runnable() {
@Override
public void run() {
// your condition and code here
if (seekbar progress changes){
yourTextView.SetText(newString);
}
}
});
}
};
seekBarTimer.scheduleAtFixedRate(seekbarTimerTask, 1000, 1000);
