android定时器、消息任务与问题解决

int times = getTimes();final int[] i = {times};Timer timer = new Timer();// 生成文件

// 解决Can't create handler inside thread that has not called Looper.prepare()问题Looper.prepare();final Handler handler = new Handler() {    public void handleMessage(Message msg) {        if (msg.what == 1) {            doThing(filePath, p_data);        }        super.handleMessage(msg);    };};Looper.loop();// 采集中...final int[] iDataIndex = {0};TimerTask task = new TimerTask() {    @Override    public void run() {        doThings();        i[0]--;        // 完成采集        if(i[0] == 0) {            Message message = new Message();            message.what = 1;            handler.sendMessage(message);            cancel();        }    }};// 开始采集timer.schedule(task, 0, 1000); // 0s后执行task,经过100ms再次执行
