BirthDate on Registration Page，Eclipse

Question

如何添加一个简单的日历，当用户点击“出生日期字段”时，它将直接指向另一个页面或具有日历的弹出框，因此用户可以选择他/她的出生日期？我正在用PhoneGap 1.4.1在eclipse中开发一个android应用程序，很多谢谢你们。

Answer 1

这里是我做过什么：

为默认值创建一个日历实例：

//class level variables 
private int mYear; 
private int mMonth; 
private int mDay; 
static final int DATE_DIALOG_ID = 0; 
private DatePickerDialog.OnDateSetListener mDateSetListener; 

//inside onCreate 
final Calendar c = Calendar.getInstance(); 
    mYear = c.get(Calendar.YEAR)-20; 
    mMonth = c.get(Calendar.MONTH); 
    mDay = c.get(Calendar.DAY_OF_MONTH); //Default DOB is (today - 20) years 

    //date picker things 
    mDateSetListener = new DatePickerDialog.OnDateSetListener() { 
     public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { 
        mYear = year; 
        mMonth = monthOfYear; 
        mDay = dayOfMonth; 
        updateDisplay(); 
       } 
    }; 

更新出生的EditText字段的日期函数：对et_dob

private void updateDisplay() { 
    et_dob.setText(new StringBuilder().append(mMonth+1).append("/").append(mDay).append("/").append(mYear).append(" ")); 
    //month is 0 based so 1 is added in mMonth; 
} 

onClickListener

showDialog(DATE_DIALOG_ID); //DATE_DIALOG_ID = 0; 

然后在你的活动覆盖onCreateDialog：

@Override 
protected Dialog onCreateDialog(int id) { 
    // TODO Auto-generated method stub 
    switch (id) { 
    case DATE_DIALOG_ID: 
     return new DatePickerDialog(this, 
        mDateSetListener, 
        mYear, mMonth, mDay); 
    } 
    return null;   
} 

当你点击EditText et_dob时，你会看到类似这样的东西。

这里是XML文件

<LinearLayout android:layout_height="wrap_content" android:layout_width="wrap_content" 
    android:layout_gravity="center_horizontal" android:paddingLeft="12dp" 
    android:paddingRight="12dp" android:paddingTop="30dp"> 

    <com.wheel.WheelView android:id="@+id/day" 
     android:layout_height="wrap_content" android:layout_width="46dp" /> 
    <com.wheel.WheelView android:id="@+id/month" 
     android:layout_height="wrap_content" android:layout_width="100dp" /> 
    <com.wheel.WheelView android:id="@+id/year" 
     android:layout_height="wrap_content" android:layout_width="wrap_content" /> 
</LinearLayout>
