*記錄開發中的問題，方便以后自已回憶,2017-07-17 記錄

在開發一個語音的線程中，發現有如下事情，系統越來越慢，也越來越卡，打到

adb shell 輸 入 top 查看系統資源,發現 CPU占用率節節升高.我的去。*

最終發現是線程沒有關閉，而不停的創建新的線程 ,

private class TrackThred extends Thread {

private byte[] TTSResult;

private volatile boolean stop = false;

private List bytes = new ArrayList<>();

private boolean isTrack = true;

private void setTTS(byte[] ttsResult) {

bytes.add(ttsResult);

}

@Override

public void run() {

super.run();

audioTrack.play();

//audioTrack.getPlaybackHeadPosition();

int i = 0;

**while (isTrack&&!stop) {** //這個地方沒有加控制開關，在重新 new TrackThred 時發現多次創建的問題

if(i < bytes.size()-1) {

TTSResult = bytes.get(i);

audioTrack.write(TTSResult, 0, TTSResult.length);

i++;

}

}

}

public void onStop() {

isTrack = false;

audioTrack.stop();

}

}
