Android DatePicker如何設置偵聽器和所選日期以顯示和設置日期

Question

如何設置此日期選擇器以顯示兩個選定的日期，例如在選擇航班時顯示的日期？

碼：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:orientation="vertical"
    tools:context=".MainActivity" >
    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">

            <DatePicker
                android:id="@+id/pickerdate"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"/>
            <TextView
                android:id="@+id/info"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"/>

        </LinearLayout>
    </ScrollView>

</LinearLayout>

public class Tab2 extends Fragment {

    DatePicker pickerDate;
    TextView info;

    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        final View v = inflater.inflate(R.layout.tab2,container,false);

        info = (TextView)v.findViewById(R.id.info);
        pickerDate = (DatePicker)v.findViewById(R.id.pickerdate);

        Calendar today = Calendar.getInstance();

        pickerDate.init(
                today.get(Calendar.YEAR),
                today.get(Calendar.MONTH),
                today.get(Calendar.DAY_OF_MONTH),
                new DatePicker.OnDateChangedListener(){

                    @Override
                    public void onDateChanged(DatePicker view,
                                              int year, int monthOfYear,int dayOfMonth) {
                        Toast.makeText(v.getContext(),
                                "onDateChanged", Toast.LENGTH_SHORT).show();

                        info.setText(
                                "Year: " + year + "\n" +
                                        "Month of Year: " + monthOfYear + "\n" +
                                        "Day of Month: " + dayOfMonth);

                    }});
        return v;
    }
}

我希望能夠選擇“到”和“從”日期，以便“從”開始的日期是將來的日期或大於“到”的日期。 如上所示，這會顯示在日歷圖像上。 謝謝

您要查找的關鍵字是“范圍”。 這是一個android庫的鏈接，用於標記日期之間的范圍。
