螺纹使用在Android媒体播放器搜索栏 [英] Thread using for seekbar on android mediaplayer

问题描述

如何创建一个线程，将检查乐曲位置每秒移动根据歌曲的位置搜索栏。我使用的打击code这是玩只有两个songs..then它从我的applicatin敬而远之

 公共类值存取工具MediaPlayer.On preparedListener
         {            在prepared（MediaPlayer的MPS）公共无效{
                // TODO自动生成方法存根
                seekbar.setMax（mp.getDuration（））;
                 新主题（新的Runnable接口（）{                  公共无效的run（）{
                          而（MP =空＆安培;！＆安培; mp.getCurrentPosition（）＆LT; mp.getDuration（））
                          {
                              seekbar.setProgress（mp.getCurrentPosition（））;
                              消息味精=新的Message（）;
                              INT米利斯= mp.getCurrentPosition（）;                              msg.obj =米利斯/ 1000;                               尝试{
                                   视频下载（100）;
                               }
                               赶上（InterruptedException的E）{
                                  e.printStackTrace（）;
                               }
                          }
                  }
          }）。开始（）;
            }
 

解决方案

下面的编码工作正常

 公共类SETP实现MediaPlayer.On $ P $ {pparedListener    在prepared（MediaPlayer的MPS）公共无效{
        // TODO自动生成方法存根
        seekbar.setMax（mp.getDuration（））;
        的System.out.println（CURPOS+ mp.getCurrentPosition（））;
        新主题（新的Runnable接口（）{
            公共无效的run（）{
                尝试{
                    而（熔点=空＆放大器;！＆放大器; mp.getCurrentPosition（）＆所述; mp.getDuration（））{
                        seekbar.setProgress（mp.getCurrentPosition（））;
                        消息味精=新的Message（）;
                        INT米利斯= mp.getCurrentPosition（）;                        msg.obj =米利斯/ 1000;                        尝试{
                            视频下载（100）;
                        }赶上（InterruptedException的E）{
                            e.printStackTrace（）;
                            的System.out.println（中断exeption+ E）;
                        }
                    } //结束时
                }赶上（例外五）{
                    e.printStackTrace（）;
                    的System.out.println（我的异常+ E）;
                }
            }
        }）。开始（）;
    }
}
 

How to create a thread that will check the song position every second and move the seekbar based on the song position. i used the blow code it's play only two songs..then it's turn away from my applicatin

public class setp implements MediaPlayer.OnPreparedListener  
         {

            public void onPrepared(MediaPlayer mps) {
                // TODO Auto-generated method stub
                seekbar.setMax(mp.getDuration());
                 new Thread(new Runnable() {

                  public void run() {
                          while(mp!=null && mp.getCurrentPosition()<mp.getDuration())
                          {
                              seekbar.setProgress(mp.getCurrentPosition());
                              Message msg=new Message();
                              int millis = mp.getCurrentPosition();

                              msg.obj=millis/1000;

                               try {
                                   Thread.sleep(100);
                               } 
                               catch (InterruptedException e) {
                                  e.printStackTrace();
                               }
                          }
                  }
          }).start();
            }

解决方案

the below coding is working fine

public class setp implements MediaPlayer.OnPreparedListener {

    public void onPrepared(MediaPlayer mps) {
        // TODO Auto-generated method stub
        seekbar.setMax(mp.getDuration());
        System.out.println("curpos" + mp.getCurrentPosition());
        new Thread(new Runnable() {
            public void run() {
                try {
                    while (mp != null && mp.getCurrentPosition() < mp.getDuration()) {
                        seekbar.setProgress(mp.getCurrentPosition());
                        Message msg = new Message();
                        int millis = mp.getCurrentPosition();

                        msg.obj = millis / 1000;

                        try {
                            Thread.sleep(100);
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                            System.out.println("interrupt exeption" + e);
                        }
                    } // end while
                } catch (Exception e) {
                    e.printStackTrace();
                    System.out.println("my Exception" + e);
                }
            }
        }).start();
    }
}
