android - 如何将 datepickerdialog 中选定的日期传递给 Cursor

Question

我正在编写一个代码，用于使用日期选择器对话框获取选定日期的未接来电列表。我正在使用按钮来显示选定的日期。我能够获取未接来电列表并能够选择日期，但我不确定如何将所选日期传递到光标查询以获取该日期的未接来电列表。

public class missnew extends ActionBarActivity implements View.OnClickListener,DatePickerDialog.OnDateSetListener,SwipeRefreshLayout.OnRefreshListener{

private int day;
private int month;
private int year;
private Calendar calender;
private Button button;
private TextView textView;
private ScrollView scrollview;
private DatePickerDialog datePickerDialog;
private SwipeRefreshLayout swipeRefreshLayout;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_missnew);

    button = (Button)findViewById(R.id.button);
    textView = (TextView)findViewById(R.id.textview);
    scrollview = (ScrollView)findViewById(R.id.scrollView);

    swipeRefreshLayout = (SwipeRefreshLayout)findViewById(R.id.swipe);
    swipeRefreshLayout.setOnRefreshListener(this);
    //swipeRefreshLayout.setColorSchemeColors(android.R.color.holo_blue_bright, android.R.color.holo_green_light,
           // android.R.color.holo_orange_light, android.R.color.holo_red_light);

    swipeRefreshLayout.setDistanceToTriggerSync(20);
    swipeRefreshLayout.setSize(1);


    calender = Calendar.getInstance(Locale.getDefault());

    button.setOnClickListener(this);

    day=calender.get(Calendar.DAY_OF_MONTH);
    month=calender.get(Calendar.MONTH);
    year=calender.get(Calendar.YEAR);

    setupdate(day, month, year);

   // String selection = CallLog.Calls.DATE + ">?", new String[] { String.valueOf(Fdate.getBytes())};
    SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-yyy");


   // Long l = Long.parseLong(Fdate);


    Cursor managedCursor = getContentResolver().
            query(

        String Tdate=formatter.format(callDayTime);

        String dir = null;

    textView.setText(sb);
}





private void setupdate(int day, int month, int year) {

    button.setText(String.valueOf(day) + "/" + String.valueOf(month + 1) + "/" +String.valueOf(year));


}


@Override

@Override

    setupdate(year,monthOfYear,dayOfMonth);


}

@Override

    (new Handler()).postDelayed(new Runnable() {
        @Override
        public void run() {
            swipeRefreshLayout.setRefreshing(false);
            getCallDetails();
        }
    }, 5000);

    }
}

使用此功能可以根据日期获取通话列表。我只是按照你的代码写的，

String dateText = button.getText(); // Time in millsec

SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy"); // assuming date text is in "MM/dd/yyyy" format and I'm doing this.
Date date = sdf.parse(dateText);  


Cursor c = contentResolver.query(CallLog.Calls.CONTENT_URI,
                null,
                CallLog.Calls.DATE + ">?",
                new String[] { String.valueOf(date.getTime())},
                strOrder);
