如何建立建立2按鈕，選取日期＋時間(DatePickerDialog、TimePickerDialog)到editText：


注意：整個事件程式碼都必須放在
onCreate() 
{  
}
下面
..........

範例：

import android.widget.*;
import android.view.*;

import java.util.Calendar;
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.app.TimePickerDialog;





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

	
	// button1 Date日期 事件處理程序
	public void button1_Click(View view) { 
	    showDialog(0);     
	   
	}
	// button2 Time時間 事件處理程序
	public void button2_Click(View view) { 
	    showDialog(1); 
	}
	
	Calendar dt = Calendar.getInstance();
	
	protected Dialog onCreateDialog(int id) {
	    switch (id) {
	    case 0: // 傳回 日期 DatePickerDialog對話方塊
	 	  DatePickerDialog dDialog = new DatePickerDialog(this,
	 	     new DatePickerDialog.OnDateSetListener() {
				 public void onDateSet(DatePicker view, int year, 
					  int monthOfYear,	int dayOfMonth) {	
					 
			//程式碼寫在這裡							 
			//年=year, 月=monthOfYear+1, 日=dayOfMonth

			 	
			   	 }							   	
			  }, dt.get(Calendar.YEAR),
				 dt.get(Calendar.MONTH),
				 dt.get(Calendar.DAY_OF_MONTH));
	 	  return dDialog;
	 	  
	 	  
	    case 1: // 傳回TimePickerDialog對話方塊
	 	  TimePickerDialog tDialog = new TimePickerDialog(this,
	 		 new TimePickerDialog.OnTimeSetListener() {
	 		 @Override
	 	  	 public void onTimeSet(TimePicker view,
	 	  			 int hourOfDay, int minute) {
	 		 
			//程式碼寫在這裡
			//時=hourOfDay, 分=minute

	 		 }
	 	  }, dt.get(Calendar.HOUR),dt.get(Calendar.MINUTE),true);
	  	  return tDialog;
	    }
	    return null;
	 }  // end of Dialog onCreateDialog()
