Android滑动选择的日期选择框

效果图如下。

实现也很简单，使用的是Android的DatePicker控件。AlertDialog实现。

首先是布局文件：date_picker_dialog.xml

<?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:gravity="center_horizontal"
    android:orientation="horizontal"
    android:paddingTop="10dp" >

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center_horizontal"
        android:orientation="vertical"
        android:padding="5dip" >

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="开始日期" />

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

</LinearLayout>

实现类：DoubleDatePickerDialog.java

package com.example.doubledatepicker;

import java.lang.reflect.Field;

import android.app.AlertDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.content.DialogInterface.OnClickListener;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.DatePicker;
import android.widget.DatePicker.OnDateChangedListener;

public class DoubleDatePickerDialog extends AlertDialog implements OnClickListener, OnDateChangedListener {

    private static final String START_YEAR = "start_year";
    private static final String END_YEAR = "end_year";
    private static final String START_MONTH = "start_month";
    private static final String END_MONTH = "end_month";
    private static final String START_DAY = "start_day";
    private static final String END_DAY = "end_day";

    private final DatePicker mDatePicker_start;  //开始

    private final OnDateSetListener mCallBack;

    public interface OnDateSetListener {

        void onDateSet(DatePicker startDatePicker, int startYear, int startMonthOfYear, int startDayOfMonth);
    }

    public DoubleDatePickerDialog(Context context, OnDateSetListener callBack, int year, int monthOfYear, int dayOfMonth) {
        this(context, 0, callBack, year, monthOfYear, dayOfMonth);
    }

    public DoubleDatePickerDialog(Context context, int theme, OnDateSetListener callBack, int year, int monthOfYear,
            int dayOfMonth) {
        this(context, 0, callBack, year, monthOfYear, dayOfMonth, true);
    }

    public DoubleDatePickerDialog(Context context, int theme, OnDateSetListener callBack, int year, int monthOfYear,
            int dayOfMonth, boolean isDayVisible) {
        super(context, theme);

        mCallBack = callBack;

        Context themeContext = getContext();
        setButton(BUTTON_POSITIVE, "确 定", this);
        setButton(BUTTON_NEGATIVE, "取 消", this);

        setIcon(0);

        LayoutInflater inflater = (LayoutInflater) themeContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View view = inflater.inflate(R.layout.date_picker_dialog, null);
        setView(view);
        mDatePicker_start = (DatePicker) view.findViewById(R.id.datePickerStart);
        mDatePicker_start.init(year, monthOfYear, dayOfMonth, this);

        if (!isDayVisible) {
            hidDay(mDatePicker_start);
        }
    }

    /**
     * 隐藏DatePicker中的日期显示
     *
     * @param mDatePicker
     */
    private void hidDay(DatePicker mDatePicker) {
        Field[] datePickerfFields = mDatePicker.getClass().getDeclaredFields();
        for (Field datePickerField : datePickerfFields) {
            if ("mDaySpinner".equals(datePickerField.getName())) {
                datePickerField.setAccessible(true);
                Object dayPicker = new Object();
                try {
                    dayPicker = datePickerField.get(mDatePicker);
                } catch (IllegalAccessException e) {
                    e.printStackTrace();
                } catch (IllegalArgumentException e) {
                    e.printStackTrace();
                }
                ((View) dayPicker).setVisibility(View.GONE);
            }
        }
    }

    public void onClick(DialogInterface dialog, int which) {
        if (which == BUTTON_POSITIVE)
            tryNotifyDateSet();
    }

    @Override
    public void onDateChanged(DatePicker view, int year, int month, int day) {
        if (view.getId() == R.id.datePickerStart)
            mDatePicker_start.init(year, month, day, this);
    }

    /**
     * 获得开始日期的DatePicker
     *
     * @return The calendar view.
     */
    public DatePicker getDatePickerStart() {
        return mDatePicker_start;
    }

    public void updateStartDate(int year, int monthOfYear, int dayOfMonth) {
        mDatePicker_start.updateDate(year, monthOfYear, dayOfMonth);
    }

    public void updateEndDate(int year, int monthOfYear, int dayOfMonth) {
    }

    private void tryNotifyDateSet() {
        if (mCallBack != null) {
            mDatePicker_start.clearFocus();
            mCallBack.onDateSet(mDatePicker_start, mDatePicker_start.getYear(), mDatePicker_start.getMonth(),
                    mDatePicker_start.getDayOfMonth());
        }
    }

    @Override
    protected void onStop() {
        super.onStop();
    }

    @Override
    public Bundle onSaveInstanceState() {
        Bundle state = super.onSaveInstanceState();
        state.putInt(START_YEAR, mDatePicker_start.getYear());
        state.putInt(START_MONTH, mDatePicker_start.getMonth());
        state.putInt(START_DAY, mDatePicker_start.getDayOfMonth());
        return state;
    }

    @Override
    public void onRestoreInstanceState(Bundle savedInstanceState) {
        super.onRestoreInstanceState(savedInstanceState);
        int start_year = savedInstanceState.getInt(START_YEAR);
        int start_month = savedInstanceState.getInt(START_MONTH);
        int start_day = savedInstanceState.getInt(START_DAY);
        mDatePicker_start.init(start_year, start_month, start_day, this);

        int end_year = savedInstanceState.getInt(END_YEAR);
        int end_month = savedInstanceState.getInt(END_MONTH);
        int end_day = savedInstanceState.getInt(END_DAY);

    }
}

使用时创建出来对象实现onDateSet方法就可以了。测试类xml文件:activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/LinearLayout01"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <EditText
        android:id="@+id/et"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:cursorVisible="false"
        android:editable="false" />

    <Button
        android:id="@+id/dateBtn"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="日期对话框" />

</LinearLayout>

测试类，MainActivity.java

package com.example.doubledatepicker;

import java.util.Calendar;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.TextView;

public class MainActivity extends Activity {

    Button btn;
    TextView et;

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

        btn = (Button) findViewById(R.id.dateBtn);
        et = (TextView) findViewById(R.id.et);

        btn.setOnClickListener(new View.OnClickListener() {
            Calendar c = Calendar.getInstance();

            @Override
            public void onClick(View v) {
                new DoubleDatePickerDialog(MainActivity.this, 0, new DoubleDatePickerDialog.OnDateSetListener() {

                    @Override
                    public void onDateSet(DatePicker startDatePicker, int startYear, int startMonthOfYear,
                            int startDayOfMonth
                          ) {
                        String textString = String.format("%d-%d-%d\n", startYear,
                                startMonthOfYear + 1, startDayOfMonth);
                        et.setText(textString);
                    }
                }, c.get(Calendar.YEAR), c.get(Calendar.MONTH), c.get(Calendar.DATE), true).show();
            }
        });
    }
}

清单文件：有些版本显示的是不同的效果，注意一下sdk版本问题。
