Android时间选择器、日期选择器实现代码

Sure! Here is a detailed guide on implementing the code for Android time picker and date picker. I will provide two examples to illustrate the process.

Time Picker Implementation

To implement a time picker in Android, follow these steps:

1. Add a TimePicker widget to your layout XML file:

<TimePicker
    android:id=\"@+id/timePicker\"
    android:layout_width=\"wrap_content\"
    android:layout_height=\"wrap_content\"
/>

1. In your activity or fragment, initialize the TimePicker and set a listener to handle the selected time:

TimePicker timePicker = findViewById(R.id.timePicker);
timePicker.setOnTimeChangedListener(new TimePicker.OnTimeChangedListener() {
    @Override
    public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
        // Handle the selected time
        // hourOfDay and minute variables contain the selected time
    }
});

That's it! You have successfully implemented a time picker in your Android application.

Date Picker Implementation

To implement a date picker in Android, follow these steps:

1. Add a DatePicker widget to your layout XML file:

<DatePicker
    android:id=\"@+id/datePicker\"
    android:layout_width=\"wrap_content\"
    android:layout_height=\"wrap_content\"
/>

1. In your activity or fragment, initialize the DatePicker and set a listener to handle the selected date:

DatePicker datePicker = findViewById(R.id.datePicker);
datePicker.init(year, month, dayOfMonth, new DatePicker.OnDateChangedListener() {
    @Override
    public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        // Handle the selected date
        // year, monthOfYear, and dayOfMonth variables contain the selected date
    }
});

In the init() method, you can pass the initial year, month, and day of the date picker.

That's it! You have successfully implemented a date picker in your Android application.

These examples demonstrate the basic implementation of time picker and date picker in Android. You can further customize the appearance and behavior of these pickers based on your application's requirements.
