android 日期控件对话框

有时候，我用到的日期控件的时候，要用对话的形式体现出来的，下面开始吧：

1.创建一个android-time

2.包名：com.app

3.主activity的名字:MainActivity

4.布局文件：main.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="fill_parent"    android:orientation="vertical" >    <TextView        android:id="@+id/tv"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="@string/hello" />    <Button        android:id="@+id/button1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="Button" /></LinearLayout>

5.activity的代码

package com.app;

import java.text.SimpleDateFormat;import java.util.Calendar;import java.util.Locale;import com.app.R;import com.app.view.DatePickText;import android.app.Activity;import android.app.DatePickerDialog;import android.app.Dialog;import android.app.TimePickerDialog;import android.content.Context;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.DatePicker;import android.widget.TextView;import android.widget.TimePicker;public class MainActivity extends Activity {public static final int DATE = 0;public static final int TIME = 1;private final Calendar cal = Calendar.getInstance(Locale.SIMPLIFIED_CHINESE);private SimpleDateFormat df;private TextView edit ;private Button button1 ;    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        df = new SimpleDateFormat();                this.edit = (TextView) this.findViewById(R.id.tv) ;              this.button1 = (Button) this.findViewById(R.id.button1) ;     this.button1.setOnClickListener(new OnClickListener(){@Overridepublic void onClick(View v) {// TODO Auto-generated method stubbuildDateOrTimeDialog(MainActivity.this) ;}}) ;            }        private void buildDateOrTimeDialog(Context context) {df = new SimpleDateFormat("HH:mm:SS");switch (444) {case DATE:date: new DatePickerDialog(context, listener,cal.get(Calendar.YEAR),cal.get(Calendar.MONTH),cal.get(Calendar.DAY_OF_MONTH)).show();break;case TIME:System.out.println("----------time---------------");new TimePickerDialog(context, timeListen,cal.get(Calendar.HOUR_OF_DAY), cal.get(Calendar.MINUTE),true).show();break;default:new DatePickerDialog(context, listener, cal.get(Calendar.YEAR),cal.get(Calendar.MONTH),cal.get(Calendar.DAY_OF_MONTH)).show();}}                private DatePickerDialog.OnDateSetListener listener = new DatePickerDialog.OnDateSetListener() { //@Overridepublic void onDateSet(DatePicker arg0, int arg1, int arg2, int arg3) {cal.set(Calendar.YEAR, arg1);cal.set(Calendar.MONTH, arg2);cal.set(Calendar.DAY_OF_MONTH, arg3);updateDate();}};private void updateDate() {edit.setText(df.format(cal.getTime()));}TimePickerDialog.OnTimeSetListener timeListen = new TimePickerDialog.OnTimeSetListener() {// 同DatePickerDialog控件@Overridepublic void onTimeSet(TimePicker view, int hourOfDay, int minute) {cal.set(Calendar.HOUR_OF_DAY, hourOfDay);cal.set(Calendar.MINUTE, minute);cal.set(Calendar.SECOND, cal.get(Calendar.SECOND));updateTimes();}};// 更新页面TextView的方法private void updateTimes() {edit.setText(df.format(cal.getTime()));}    }

说明的：

其中SimpleDateFormatdf = new SimpleDateFormat("HH:mm:SS"); //定义获取时间的样子

switch (444) {case DATE:date: new DatePickerDialog(context, listener,cal.get(Calendar.YEAR),cal.get(Calendar.MONTH),cal.get(Calendar.DAY_OF_MONTH)).show();break;case TIME:System.out.println("----------time---------------");new TimePickerDialog(context, timeListen,cal.get(Calendar.HOUR_OF_DAY), cal.get(Calendar.MINUTE),true).show();break;default:new DatePickerDialog(context, listener, cal.get(Calendar.YEAR),cal.get(Calendar.MONTH),cal.get(Calendar.DAY_OF_MONTH)).show();}

定义的对话框中，我们要不要显示时间，你可以更改switch（DATA||TIME）来选择你要的样子。

如果你还是看不懂上面的代码，或者用起来有问题，那么你可以联系：qq 1019990976。

觉得是无图有真相的。
