正如标题所暗示的，我对声音循环有问题，因为我不知道如何打破循环。循环运行时，我无法控制设备的音量。

public void onClick(View view) {
            // TODO Auto-generated method stub
                boolean on = ((ToggleButton) view).isChecked();
                if (on){
                     boolean is = true;
                     android.os.Process.setThreadPriority(android.os.Process.THREAD_PRIORITY_URGENT_AUDIO);
                     int buffersize = AudioRecord.getMinBufferSize(20000, AudioFormat.CHANNEL_IN_MONO, AudioFormat.ENCODING_PCM_16BIT);
                     AudioRecord arec = new AudioRecord(MediaRecorder.AudioSource.MIC, 20000, AudioFormat.CHANNEL_IN_MONO, AudioFormat.ENCODING_PCM_16BIT, buffersize);
                     AudioTrack atrack = new AudioTrack(AudioManager.STREAM_MUSIC, 20000, AudioFormat.CHANNEL_OUT_MONO, AudioFormat.ENCODING_PCM_16BIT, buffersize, AudioTrack.MODE_STREAM);
                     atrack.setPlaybackRate(20000);
                     byte[] buffer = new byte[buffersize];
                     arec.startRecording();
                     atrack.play();
                     while(is){
                         arec.read(buffer, 0, buffersize);
                         atrack.write(buffer, 0, buffer.length);
                     }
                     arec.stop();
                        atrack.stop();
                        is = false;
                           }
                           }});

        }

使用arec.release()；而atrack.release()不是这可能会帮助你arec.stop();，atrack.stop 祝你好运...... :)

您可以使用AudioTrack.stop()或AudioTrack.pause()

嗯......你首先设置布尔值“is = true”。然后你有一个 while 循环“while (is)”，它是一个无限循环，因为“is”将永远为真，并且永远不会在你将它设置为“假”的那一行。你想在 while-loop 中做什么？
