1. 声明EditText变量，并关联到相应控件上

private EditText sellStartTime;private EditText sellEndTime;

sellStartTime = (EditText)findViewById(R.id.editSellStartTime);sellEndTime = (EditText)findViewById(R.id.editSellEndTime);

2. 日期选择器函数

private DatePickerDialog.OnDateSetListener mDateSetListener =            new DatePickerDialog.OnDateSetListener() {public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {                    mYear = year;                    String mm;                    String dd;                    if(monthOfYear<=9)                    {                    mMonth = monthOfYear+1;                    mm="0"+mMonth;                    }                    else{                    mMonth = monthOfYear+1;                    mm=String.valueOf(mMonth);                    }                    if(dayOfMonth<=9)                    {                    mDay = dayOfMonth;                    dd="0"+mDay;                    }                    else{                    mDay = dayOfMonth;                    dd=String.valueOf(mDay);                    }                    mDay = dayOfMonth;                    if(timeFlag == 0) {                    sellStartTime.setText(String.valueOf(mYear)+"-"+mm+"-"+dd);                    }else {                    sellEndTime.setText(String.valueOf(mYear)+"-"+mm+"-"+dd);                    }                }            };       protected Dialog onCreateDialog(int id) {    switch (id) {        case 0:        return new DatePickerDialog(this,                    mDateSetListener,                    mYear, mMonth, mDay);        case 1:        return new DatePickerDialog(this,                    mDateSetListener,                    mYear, mMonth, mDay);        }    return null;    }        // 隐藏手机键盘    private void hideIM(View edt){        try {             InputMethodManager im = (InputMethodManager) getSystemService(Activity.INPUT_METHOD_SERVICE);             IBinder  windowToken = edt.getWindowToken();             if(windowToken != null) {                 im.hideSoftInputFromWindow(windowToken, 0);             }         } catch (Exception e) {                    }     }

3. 注册监听器，当EditText获得焦点时，或者被点击时，打开日期选择器

                sellStartTime.setOnClickListener(new OnClickListener(){                public void onClick(View v) {                timeFlag = 0;                showDialog(0);}        });sellEndTime.setOnClickListener(new OnClickListener() {public void onClick(View v) {timeFlag = 1;showDialog(1);}});sellStartTime.setOnFocusChangeListener(new OnFocusChangeListener() {public void onFocusChange(View v, boolean hasFocus) {if (hasFocus == true) {timeFlag = 0;hideIM(v);showDialog(0);  }}});sellEndTime.setOnFocusChangeListener(new OnFocusChangeListener() {public void onFocusChange(View v, boolean hasFocus) {if (hasFocus == true) {timeFlag = 1;hideIM(v);showDialog(1);  }}});

4. 在包含EditText的LinearLayout中，添加语句

android:focusable="true"  android:focusableInTouchMode="true"

这句话，是为了防止EditText自动获取焦点，触发日期选择器。
