android - 如何只录制1分钟的音频？

Question

在我的android应用中，我只需要录制音频1分钟？有谁能帮助我录制一定时间的音频？我已经编写了用于录制音频的代码，只有在按下停止按钮时它才会停止，但是我需要在1分钟后自动停止录制...

这是我的代码..但是没有用

       try {
             recorder.prepare();

           recorder.start();
         //Declare the timer

           Timer t = new Timer();
           //Set the schedule function and rate
           t.scheduleAtFixedRate(new TimerTask() {

               @Override
               public void run() {

                   runOnUiThread(new Runnable() {

                        @Override
                        public void run() {
                            Toast.makeText(AudioRecordingActivity.this, "record successfullly ",
                                    Toast.LENGTH_SHORT).show();
                    i1=i1+1;
                        }

                    });


                   //Called each time when 1000 milliseconds (1 second) (the period parameter)
               }

           },
           //Set how long before to start calling the TimerTask (in milliseconds)
           0,
           //Set the amount of time between each execution (in milliseconds)
           10*1000);

           if (null != recorder) {
            recorder.stop();
            recorder.reset();
            recorder.release();

            recorder = null;
            Toast.makeText(AudioRecordingActivity.this, "record successfullly",
                    Toast.LENGTH_SHORT).show();

           }

                } catch (IllegalStateException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}

试试下面的代码

recorder.start();
   new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
        recorder.stop();
         }
                }, 60000);
