Question

我正在尝试设计一个在网站上进行多个API调用的程序（每个“名称”都有几种模式，我必须循环才能继续使用下一个名称）。问题是，您只能每秒调用一次API。我认为处理程序是要走的路，但现在我不这么认为。

它在循环中运行得很好，但我不这么认为。我收到以下错误：

编辑：弄清楚这是由

当我在异步任务中进行此调用时：

String [] metrics = r.getStringArray（R.array.metric_apicall）;

我认为我的代码不适合我想要做的事情。任何人都可以告诉我这是否是正确的方法？...另外，APICallData（MainActivity.this，app，mode）.execute（）;是一个异步任务。

//Other code above this irrelevant

    mApp = 0;
    mMode = 0;
    callAPI(mMode, names[mApp]);
    mMode++;

    while (mApp < names.length) {
        while (mMode < metrics.length) {
            Handler handler = new Handler(); 
            handler.postDelayed(new Runnable() { 
                public void run() { 
                    callAPI(mMode, names[mApp]);

                }
            }, 1010); 
            mMode++;
        }
        mMode = 0;
        mApp++;
    }

private void callAPI(int mode, String app) {
    new APICallData(MainActivity.this, app, mode).execute();
}

我认为你应该使用Timer和TimerTask并以1秒的间隔执行它。
