关于android 进程CPU占用率高的原因分析

来源：互联网 发布：中国知网数据库检索 编辑：程序博客网 时间：2024/05/22 15:12

*记录开发中的问题，方便以后自已回忆,2017-07-17 记录
在开发一个语音的线程中，发现有如下事情，系统越来越慢，也越来越卡，打到
adb shell 输 入 top 查看系统资源,发现 CPU占用率节节升高.我的去。*
最终发现是线程没有关闭，而不停的创建新的线程 ,

private class TrackThred extends Thread {

    private byte[] TTSResult;    private volatile boolean stop = false;    private List<byte[]> 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) {**  //这个地方没有加控制开关，在重新 new TrackThred 时发现多次创建的问题            if(i < bytes.size()-1) {                TTSResult = bytes.get(i);                audioTrack.write(TTSResult, 0, TTSResult.length);                i++;            }        }    }    public void onStop() {        isTrack = false;        audioTrack.stop();    }}
