android - 将时间选择器添加到日期选择器android

Question

我正在尝试将时间选择器 添加到日期选择器。我是 Java 的初学者，也许有人可以告诉我正确的方法？我希望时间选择器显示在日历 View 的顶部，在我选择日期后，时间选择器会弹出。是否可以 ？在 xml 文件中，只有几个 EditText 字段已在此类中声明。

 public class CompletedWorksActivity extends Activity implements
        DatePickerDialog.OnDateSetListener, OnClickListener, OnTimeSetListener {
    private TextView text_date;
    private Button search;
    private EditText from;
    private EditText to;
    private int yearfrom;
    private int monthfrom;
    private int dayfrom;
    private int hourfrom;
    private int minfrom;
    private int yearto;
    private int monthto;
    private int dayto;
    private int hourto;
    private int minto;
    private int hour;
    private int min;
    private DatePickerDialog date_picker;
    private TimePickerDialog time_picker;
    private boolean fromEdit;
    private boolean toEdit;

    @Override
    protected void onCreate(Bundle menuinstance) {
        super.onCreate(menuinstance);
        setContentView(R.layout.completed_works);

        Intent intent = getIntent(); // gaunam
        User user = (User) intent.getSerializableExtra("user");

        from = (EditText) findViewById(R.id.datefrom);
        to = (EditText) findViewById(R.id.dateto);
        Calendar cal = Calendar.getInstance();
        hour = cal.get(Calendar.HOUR_OF_DAY);
        min = cal.get(Calendar.MINUTE);
        date_picker = new DatePickerDialog(this, this, cal.get(Calendar.YEAR),
                cal.get(Calendar.MONTH), cal.get(Calendar.DAY_OF_MONTH));
        date_picker.getDatePicker().setCalendarViewShown(true);
        date_picker.getDatePicker().setSpinnersShown(false);
        time_picker = new TimePickerDialog(this, this, hour, min, true);
        from.setOnFocusChangeListener(focusListener);
        to.setOnFocusChangeListener(focusListener);
        time_picker.set

        search = (Button) findViewById(R.id.searchSubmit);

        // search.setOnClickListener(searchlistener);
    }

    @Override
    public void onDateSet(DatePicker dp, int y, int m, int d) {
        String cheapDate = y + "-" + (m + 1) + "-" + d;
        View v = getCurrentFocus();
        if (v == from) {
            yearfrom = y;
            monthfrom = m;
            dayfrom = d;
            Log.d("year from ", "" + yearfrom + monthfrom + dayfrom);
        } else {
            yearto = y;
            monthto = m;
            dayto = d;
            Log.d("year to ", "" + yearto + monthto + dayto);
            // Toast.makeText(getApplicationContext(),yearto+monthto+dayto ,
            // Toast.LENGTH_LONG ).show();
        }
        if (fromEdit) {
            from.setText(cheapDate);
        } else {
            to.setText(cheapDate);
        }

    }

    private View.OnClickListener searchlistener = new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

        }
    };

    private View.OnFocusChangeListener focusListener = new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (hasFocus) {
                EditText edit = (EditText) v;
                int len = edit.getText().toString().length();

                if (edit == findViewById(R.id.datefrom)) {
                    Toast.makeText(getApplicationContext(), "Data nuo ? ",
                            Toast.LENGTH_LONG).show();
                    fromEdit = v.getId() == R.id.datefrom;
                    date_picker.show();
                } else {
                    Toast.makeText(getApplicationContext(), "Data iki ? ",
                            Toast.LENGTH_LONG).show();
                    fromEdit = v.getId() == R.id.datefrom;
                    date_picker.show();

                }
            }
        }

    };

    @Override
    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
        // TODO Auto-generated method stub

    }

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub

    }



}

Android 使用 android.widget.TimePicker 组件 设置时间非常简单。

参见 this Tutorial在这里，您可以看到用户如何使用易于使用的对话框 android.app.TimePickerDialog 选择小时和分钟。
