java - ADK Java 检查日期是否等于定义的日期间隔

Question

我想检查当前日期是否等于(或包含)某个定义的日期间隔。我有这样的东西:

        Calendar c1 =  Calendar.getInstance();
        SimpleDateFormat sdf1 = new SimpleDateFormat("dd-MM-yyyy");

        Date lowerBound = null;
        Date upperBound = null;
        try {
            lowerBound = sdf1.parse("29-10-2013");
            upperBound = sdf1.parse("30-12-2013");
        } catch (ParseException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        TextView txtdate1 = (TextView) findViewById(R.id.textView1);

        if (c1.getTime().before(upperBound) && c1.getTime().after(lowerBound)) {
            txtdate1.setText("Is up to date");
        } else {
            txtdate1.setText("Is not up to date");
        }

您可以使用函数before和 after检查您的日期是否在特定范围内。

    Calendar c1 =  Calendar.getInstance();
    SimpleDateFormat sdf1 = new SimpleDateFormat("dd-MM-yyyy");

    Date lowerBound = sdf1.parse("20-10-2013");
    Date upperBound = sdf1.parse("30-12-2013");

    TextView txtdate1 = (TextView) findViewById(R.id.textView1);

    if (c1.getTime().before(upperBound) && c1.getTime().after(lowerBound)) {
        txtdate1.setText("Is up to date");
    } else {
        txtdate1.setText("Is not up to date");
    }

最酷的事情是，您可以定义一些函数，通过创建预定义函数来检查数据是否在某个定义的范围内。请参阅this例如。
