android 弹出日期滑动选择框 android日期滚动滑动选择日期选择 android

本例使用到的类比较多，所使用的自定义的控件都是老外写好的，我知识根据他给的滑动的空间的基础上美化下和添加图片罢了，不多说直接看图：

第一步：设计弹出框xml:

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

   <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="#ff424542"
        android:orientation="horizontal" 
        android:layout_above="@+id/bithday_layout"
        >
        
               <TextView
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:gravity="center_horizontal"
            android:layout_centerVertical="true"
            android:textColor="@android:color/white"
            android:text="日期" />
	<Button
            android:id="@+id/cancel"
            android:layout_width="80dip"
            android:layout_height="wrap_content"     
            android:layout_alignParentLeft="true"
            android:background="@drawable/mm_title_btn_right"
            android:text="取消"
            android:textColor="@android:color/white"
            
             />
       



 

        <Button
            android:id="@+id/submit"
            android:layout_width="80dip"
            android:layout_height="wrap_content"
            android:layout_gravity="right"
            android:background="@drawable/mm_title_act_btn"
            android:text="完成"
            android:textColor="@android:color/white" 
            android:layout_alignParentRight="true"
            />
    </RelativeLayout>
     <RelativeLayout
          android:id="@+id/bithday_layout"
         android:layout_alignParentBottom="true"
        android:layout_width="fill_parent"
        android:layout_height="220dip"
        android:gravity="center"
        android:orientation="horizontal" >

        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_marginLeft="15dip"
            android:layout_marginRight="15dip"
            android:layout_height="220dip"
            android:gravity="center"
            android:orientation="horizontal" >

            <com.example.widget.WheelView
                android:id="@+id/year"
                android:layout_width="0.0dip"
                android:layout_height="fill_parent"
                android:layout_weight="1" />

            <com.example.widget.WheelView
                android:id="@+id/month"
                android:layout_width="0.0dip"
                android:layout_height="fill_parent"
                android:layout_weight="1" 
                
                />
            <com.example.widget.WheelView
                android:id="@+id/day"
                android:layout_width="0.0dip"
                android:layout_height="fill_parent"
                android:layout_weight="1" 
                
                />
        </LinearLayout>

       <FrameLayout
            android:layout_width="fill_parent"
            android:layout_height="220.0dip"
            android:layout_gravity="center"
            android:background="@drawable/com_ttshrk_view_scroll_picker_background" >
        </FrameLayout> 
    </RelativeLayout>
</LinearLayout>

第二步：编写弹出框PopupWindow类：

import android.app.Activity;
import android.content.Context;
import android.graphics.Typeface;
import android.graphics.drawable.ColorDrawable;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup.LayoutParams;
import android.widget.Button;
import android.widget.PopupWindow;
import android.widget.TextView;
import android.widget.ViewFlipper;

import com.example.widget.NumericWheelAdapter;
import com.example.widget.OnWheelChangedListener;
import com.example.widget.WheelView;

public class SelectBirthday extends PopupWindow implements OnClickListener {

	private Activity mContext;
	private View mMenuView;
	private ViewFlipper viewfipper;
	private Button btn_submit, btn_cancel;
	private String age;
	private DateNumericAdapter monthAdapter, dayAdapter, yearAdapter;
	private WheelView year, month, day;
	private int mCurYear = 80, mCurMonth = 5, mCurDay = 14;
	private String[] dateType;

	public SelectBirthday(Activity context) {
		super(context);
		mContext = context;
		this.age = "2012-9-25";
		LayoutInflater inflater = (LayoutInflater) context
				.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
		mMenuView = inflater.inflate(R.layout.birthday, null);
		viewfipper = new ViewFlipper(context);
		viewfipper.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
				LayoutParams.WRAP_CONTENT));

		year = (WheelView) mMenuView.findViewById(R.id.year);
		month = (WheelView) mMenuView.findViewById(R.id.month);
		day = (WheelView) mMenuView.findViewById(R.id.day);
		btn_submit = (Button) mMenuView.findViewById(R.id.submit);
		btn_cancel = (Button) mMenuView.findViewById(R.id.cancel);
		btn_submit.setOnClickListener(this);
		btn_cancel.setOnClickListener(this);
		Calendar calendar = Calendar.getInstance();
		OnWheelChangedListener listener = new OnWheelChangedListener() {
			public void onChanged(WheelView wheel, int oldValue, int newValue) {
				updateDays(year, month, day);

			}
		};
		int curYear = calendar.get(Calendar.YEAR);
		if (age != null && age.contains("-")) {
			String str[] = age.split("-");
			mCurYear = 100 - (curYear - Integer.parseInt(str[0]));
			mCurMonth = Integer.parseInt(str[1]) - 1;
			mCurDay = Integer.parseInt(str[2]) - 1;
			;
		}
		dateType = mContext.getResources().getStringArray(R.array.date); 
		monthAdapter = new DateNumericAdapter(context, 1, 12, 5);
		monthAdapter.setTextType(dateType[1]);
		month.setViewAdapter(monthAdapter);
		month.setCurrentItem(mCurMonth);
		month.addChangingListener(listener);
		// year

		yearAdapter = new DateNumericAdapter(context, curYear - 100, curYear+100,
				100 - 20);
		yearAdapter.setTextType(dateType[0]);
		year.setViewAdapter(yearAdapter);
		year.setCurrentItem(mCurYear);
		year.addChangingListener(listener);
		// day

		updateDays(year, month, day);
		day.setCurrentItem(mCurDay);
		updateDays(year, month, day);
		day.addChangingListener(listener);

		viewfipper.addView(mMenuView);
		viewfipper.setFlipInterval(6000000);
		this.setContentView(viewfipper);
		this.setWidth(LayoutParams.FILL_PARENT);
		this.setHeight(LayoutParams.WRAP_CONTENT);
		this.setFocusable(true);
		ColorDrawable dw = new ColorDrawable(0x00000000);
		this.setBackgroundDrawable(dw);
		this.update();

	}

	@Override
	public void showAtLocation(View parent, int gravity, int x, int y) {
		super.showAtLocation(parent, gravity, x, y);
		viewfipper.startFlipping();
	}


	private 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);
		dayAdapter = new DateNumericAdapter(mContext, 1, maxDays,
				calendar.get(Calendar.DAY_OF_MONTH) - 1);
		dayAdapter.setTextType(dateType[2]);
		day.setViewAdapter(dayAdapter);
		int curDay = Math.min(maxDays, day.getCurrentItem() + 1);
		day.setCurrentItem(curDay - 1, true);
		int years = calendar.get(Calendar.YEAR) - 100;
		age = years + "-" + (month.getCurrentItem() + 1) + "-"
				+ (day.getCurrentItem() + 1);
	}

	/**
	 * 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(24);
		}

		protected void configureTextView(TextView view) {
			super.configureTextView(view);
			view.setTypeface(Typeface.SANS_SERIF);
		}

		public CharSequence getItemText(int index) {
			currentItem = index;
			return super.getItemText(index);
		}

	}

	public void onClick(View v) {
		this.dismiss();
	}


}

代码主要就是这两个，其他的控件类不是本人编写就不上传了，直接上源码，有需要的自己下载研究
