Android开发中的AlertDialog

最近做了一个Android项目，对AlertDialog有一些了解，贴一些心得上来。

日期选择对话框：

代码：

 

 Calendar c = Calendar.getInstance();
        DatePickerDialog ad = new DatePickerDialog(this,
                new OnDateSetListener() {
                    public void onDateSet(DatePicker view, int year,
                            int monthOfYear, int dayOfMonth) {
                        // TODO Auto-generated method stub
                        String date = String.valueOf(year) + "-"
                                + String.valueOf(monthOfYear + 1) + "-"
                                + String.valueOf(dayOfMonth);
                    }
                }, c.get(Calendar.YEAR), c.get(Calendar.MONTH), c
                        .get(Calendar.DATE));
        ad.show();

                    public void onTimeSet(TimePicker view, int hourOfDay,
                            int minute) {

                                    + String.valueOf(minute);

                        } else if (hourOfDay < 10 && minute < 10) {
                            timer = "0" + String.valueOf(hourOfDay) + ":" + "0"
                                    + String.valueOf(minute);
                        } else {
                            timer = String.valueOf(hourOfDay) + ":"
                                    + String.valueOf(minute);
                        }
                }, c.get(Calendar.HOUR_OF_DAY), c.get(Calendar.MINUTE), true);
        ad.show();

        edt.setText(text);

感悟：对于AlertDialog一类的对话框有很多布局格式，可以根据自己的需要自己去通过XML布局，然后嵌套到AlertDialog中去。
