public class TestActvity extends AppCompatActivity implements View.OnClickListener {

    Button next;
    Button previous;
    TextView textView;
    int interval = 2;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.test);
        next = (Button) findViewById(R.id.next);
        previous = (Button) findViewById(R.id.previous);
        next.setOnClickListener(this);
        previous.setOnClickListener(this);
        textView = (TextView) findViewById(R.id.textView);
        getDate(interval);
    }

    @Override
    public void onClick(View view) {

        if (view.getId() == R.id.next)

        {
            interval = interval + 7;
            getDate(interval);

        } else if (view.getId() == R.id.previous) {
            interval = interval - 7;
            getDate(interval);

        }
    }

    public void getDate(int interval) {

        try {
            Calendar c = GregorianCalendar.getInstance();
            c.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY);
            c.add(Calendar.DAY_OF_WEEK, interval - 2);
            DateFormat df = new SimpleDateFormat("yyyy-MM-dd", Locale.getDefault());
            String startDate = "", endDate = "";
            startDate = df.format(c.getTime());
            c.add(Calendar.DATE, 6);
            endDate = df.format(c.getTime());
            textView.setText(startDate + "  to  " + endDate);
            Date date = new Date();
            String modifiedDate = new SimpleDateFormat("yyyy-MM-dd").format(date);

            if ( endDate.compareTo(modifiedDate) > 0) {
                Log.d("data", "" + "");
            }
            Log.d("data", "" + "");
        } catch (Exception e) {

        }

    }


}

使用此代码,我将在周一至周日显示

  2017-7-7至2017-7-9,2017-7-10至2017-7-16,2017-7-17至2017-7-23   ,2017-7-24至2017-7-30,2017-7-31至2017-8-5 ......

接受但我想要的是,如果本周是

  

2017-7-24至2017-7-30

然后当我们点击下周它应显示它应该只显示前一周请在这个场景中建议我将比较日期。

答案 0 :(得分:0)

    if (c.getTime().after(new Date())){
        next.setVisibility(View.GONE);
    }else {
        next.setVisibility(View.VISIBLE);
    }

申请此条件并享受!!
