我想DatePickerDialog在 Android 活动本身中嵌入一个。我不希望DatePicker在单击按钮作为对话框时出现，而是将其嵌入到我的活动本身中。我曾尝试DatePicker在布局中使用视图，但这似乎与DatePickerDialog.

我DialogFragment用于创建和DatePickerDialog使用以下代码onCreateMainAcitivity.java 

    FragmentTransaction ft = getFragmentManager().beginTransaction();
    DatePickerDialogFragment datePickerDialogFragment = DatePickerDialogFragment.newInstance();

    ft.add(R.id.main_screen_layout, datePickerDialogFragment); // main_screen_layout is given as the id for the layout related to MainActivity
    ft.commit();

// DatePickerDialogFragment.java

public class DatePickerDialogFragment extends DialogFragment

implements DatePickerDialog.OnDateSetListener {

public static DatePickerDialogFragment newInstance() {
    return new DatePickerDialogFragment();
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.dialog_datepicker, container, false);
    View tv = v.findViewById(R.id.tv);

    ((TextView)tv).setText("This is a new instance");

    return v;
}

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    Calendar c = Calendar.getInstance();
    return new DatePickerDialog(getActivity(), this, 
            c.get(Calendar.YEAR),
            c.get(Calendar.MONTH),
            c.get(Calendar.DAY_OF_MONTH));
}

public void onDateSet(DatePicker view, int year, int monthOfYear,
        int dayOfMonth) {
    // TODO Auto-generated method stub

}

}

如何解决这个问题？

我在活动布局中有 DatePicker 和 DateTime。这个想法是允许两者的编辑，组成一个日期时间值并在用户单击完成/设置按钮后返回它。下面，您可以找到一些代码，显示 DatePicker 如何嵌入到布局和活动代码中：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:orientation="vertical">

    <DatePicker
        android:id="@+id/date_value"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:calendarViewShown="false" />
</LinearLayout>


public class DateSelectionActivity extends Activity {

    private DatePicker datePicker;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // ...

        this.datePicker = (DatePicker) this.findViewById(R.id.date_value);
        this.datePicker.init(calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH), null);

        // ...
    }

    private OnClickListener confirmButtonClickListener = new OnClickListener() {

            @Override
            public void onClick(View v) {

                // Get user selection
                // DateSelectionActivity.this.datePicker.getYear());
                // DateSelectionActivity.this.datePicker.getMonth());
                // DateSelectionActivity.this.datePicker.getDayOfMonth());
            }
    }
}
