安卓仿iphone日期选项器 仿iphone日期选择自定义控件

原来的DatePicker总有这样那样的不如意，看到ipad的日期选择，感觉很好，如果google android date like iphone,

得到Android Wheel,项目地址：https://code.google.com/p/android-wheel/

现在国内被墙了，下载的话，还比较麻烦，总之费劲down下来，并研究实现。

1.首先，导入down下来的wheel，导入后得到wheel工程

2.新建一个新的安卓工程DateWheel,默认配制，完成后，在工程上右键，properties，android，把wheel加入Lib

3.建立layout

<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:background="#000000"    android:orientation="vertical" >    <TextView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="center"        android:layout_margin="10dp"        android:text="请选择日期"        android:textColor="#ffffff"        android:textSize="20sp" />    <LinearLayout        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:background="@drawable/layout_bg"        android:paddingLeft="20dp"        android:paddingRight="20dp"        android:orientation="horizontal" >        <kankan.wheel.widget.WheelView            android:id="@+id/id_year"            android:layout_width="0dp"            android:layout_height="wrap_content"            android:layout_weight="1" >        </kankan.wheel.widget.WheelView>        <kankan.wheel.widget.WheelView            android:id="@+id/id_month"            android:layout_width="0dp"            android:layout_height="wrap_content"            android:layout_weight="1" >        </kankan.wheel.widget.WheelView>        <kankan.wheel.widget.WheelView            android:id="@+id/id_day"            android:layout_width="0dp"            android:layout_height="wrap_content"            android:layout_weight="1" >        </kankan.wheel.widget.WheelView>    </LinearLayout>        <Button         android:id="@+id/id_button"android:layout_gravity="right"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="确定"        />    </LinearLayout>

4.在Activity增加代码：

<pre name="code" class="java">package com.example.datewheel;import android.os.Bundle;import android.app.Activity;import java.util.Calendar;import kankan.wheel.widget.OnWheelChangedListener;import kankan.wheel.widget.WheelView;import kankan.wheel.widget.adapters.ArrayWheelAdapter;import kankan.wheel.widget.adapters.NumericWheelAdapter;import android.content.Context;import android.graphics.Typeface;import android.view.View;import android.view.ViewGroup;import android.widget.Button;import android.widget.TextView;import android.widget.Toast;public class DateActivity extends Activity {private Button button;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_day);        Calendar calendar = Calendar.getInstance();        int curYear,curMonth,curDay;        final WheelView month = (WheelView) findViewById(R.id.id_month);        final WheelView year = (WheelView) findViewById(R.id.id_year);        final WheelView day = (WheelView) findViewById(R.id.id_day);                OnWheelChangedListener listener = new OnWheelChangedListener() {            public void onChanged(WheelView wheel, int oldValue, int newValue) {                updateDays(year, month, day);            }        };    // month,beginning from 0    curMonth = calendar.get(Calendar.MONTH);    String months[] = new String[] {this.getString(R.string.january), this.getString(R.string.february),    this.getString(R.string.march), this.getString(R.string.april), this.getString(R.string.may),     this.getString(R.string.june), this.getString(R.string.july), this.getString(R.string.august),     this.getString(R.string.september), this.getString(R.string.october),     this.getString(R.string.november),this.getString(R.string.december)};    month.setViewAdapter(new DateArrayAdapter(this, months, curMonth));    //设置当前月份    month.setCurrentItem(curMonth);    month.addChangingListener(listener);    //得到当前年    curYear = calendar.get(Calendar.YEAR);    year.setViewAdapter(new DateNumericAdapter(this, curYear, curYear + 50, 0));    //设置当前年    year.setCurrentItem(curYear);    year.addChangingListener(listener);        //day    updateDays(year, month, day);    //设置当前天 从0开始    curDay=calendar.get(Calendar.DAY_OF_MONTH);    day.setCurrentItem(curDay);        //botton listener    button=(Button) findViewById(R.id.id_button);    button.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubint selecty,selectm,selectd;selecty=year.getCurrentItem();selectm=month.getCurrentItem();selectd=day.getCurrentItem();String strtmp=String.format("选择是：%d-%02d-%02d", curYear+selecty,selectm+1,selectd+1);Toast.makeText(DateActivity.this, strtmp, 1).show(); }});    }        /**     * Updates day wheel. Sets max days according to selected month and year     */    void updateDays(WheelView year, WheelView month, WheelView day) {        Calendar calendar = Calendar.getInstance();        calendar.set(Calendar.YEAR, calendar.get(Calendar.YEAR) + year.getCurrentItem());        calendar.set(Calendar.MONTH, month.getCurrentItem());                int maxDays = calendar.getActualMaximum(Calendar.DAY_OF_MONTH);        day.setViewAdapter(new DateNumericAdapter(this, 1, maxDays, calendar.get(Calendar.DAY_OF_MONTH) - 1));        int maxDay = Math.min(maxDays, day.getCurrentItem() + 1);        day.setCurrentItem(maxDay - 1, true);    }        /**     * Adapter for numeric wheels. Highlights the current value.     */    private class DateNumericAdapter extends NumericWheelAdapter {        // Index of current item        int currentItem;        // Index of item to be highlighted        int currentValue;                /**         * Constructor         */        public DateNumericAdapter(Context context, int minValue, int maxValue, int current) {            super(context, minValue, maxValue);            this.currentValue = current;            setTextSize(16);        }                @Override        protected void configureTextView(TextView view) {            super.configureTextView(view);            if (currentItem == currentValue) {                view.setTextColor(0xFF0000F0);            }            view.setTypeface(Typeface.SANS_SERIF);        }                @Override        public View getItem(int index, View cachedView, ViewGroup parent) {            currentItem = index;            return super.getItem(index, cachedView, parent);        }    }        /**     * Adapter for string based wheel.
