012、时间、日期控件

模拟小时钟控件：AnalogClock

数字小时钟控件：DigitalClock

以上两个都直接在布局文件里面放置即可

 

动态输入日期和时间：

DatePicker控件可以动态设置日期，用于用户更改年月日，DatePicker控件设置监听必须通过init()方法，传入默认初始值。

        ((DatePicker) findViewById(R.id.dp)).init(mYear, mMonth, mDay,
                new OnDateChangedListener() {
 
                    @Override
                    public void onDateChanged(DatePicker view, int year,
                            int monthOfYear, int dayOfMonth) {
                                        //日期被修改时调用
 
                    }
                });

 

TimePicker控件可以让用户动态更改时间：

 

        ((TimePicker) findViewById(R.id.tp))
                .setOnTimeChangedListener(new OnTimeChangedListener() {
 
                    @Override
                    public void onTimeChanged(TimePicker view, int hourOfDay,
                            int minute) {
                        //时间修改时调用
                    }
                });

 

 

DatePickerDialog和TimePickerDialog也可以实现日期和时间的更改，只是这种是以对话框的方式来让用户进行更改，具体用哪种，需更改需求来定，示例如下：

 

       findViewById(R.id.bt_date).setOnClickListener(new OnClickListener() {
 
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Calendar calendar = Calendar.getInstance();
                new DatePickerDialog(DatePickerDialogActivity.this,
                        new OnDateSetListener() {
 
                            @Override
                            public void onDateSet(DatePicker view, int year,
                                    int monthOfYear, int dayOfMonth) {
                                // TODO Auto-generated method stub
                                Log.e("-----------------", year + "/"
                                        + monthOfYear + "/" + dayOfMonth);
                            }
                        }, calendar.get(Calendar.YEAR), calendar
                                .get(Calendar.MONTH), calendar
                                .get(Calendar.DAY_OF_MONTH)).show();
            }
        });
 
        findViewById(R.id.bt_time).setOnClickListener(new OnClickListener() {
 
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Calendar calendar = Calendar.getInstance();
                new TimePickerDialog(DatePickerDialogActivity.this,
                        new OnTimeSetListener() {
 
                            @Override
                            public void onTimeSet(TimePicker view,
                                    int hourOfDay, int minute) {
                                // TODO Auto-generated method stub
                                Log.e("-----------------", hourOfDay + ":"
                                        + minute);
                            }
                        }, calendar.get(Calendar.HOUR_OF_DAY), calendar
                                .get(Calendar.MINUTE), true).show();
            }
        });
