Android - How to set datePickerMode="spinner" programmatically?

To set the datePickerMode to "spinner" programmatically in Android, you can do this by using the DatePicker class. Here's how you can achieve that:

Steps to Set DatePicker Mode Programmatically

  1. Create a DatePicker instance.
  2. Use the setCalendarViewShown method to hide the calendar view and show the spinner mode.

Example Code

Here's a complete example of how to create a DatePicker in spinner mode programmatically:

1. Layout XML

First, create a layout for your activity or fragment:

<!-- res/layout/activity_main.xml --> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <Button android:id="@+id/openDatePickerButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Open DatePicker" /> </LinearLayout>

2. Activity Code

Then, implement the DatePicker in your activity:

import android.app.DatePickerDialog; import android.os.Bundle; import android.view.View; import android.widget.Button; import androidx.appcompat.app.AppCompatActivity; import java.util.Calendar; public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Button openDatePickerButton = findViewById(R.id.openDatePickerButton); openDatePickerButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { openDatePicker(); } }); } private void openDatePicker() { // Get current date final Calendar calendar = Calendar.getInstance(); int year = calendar.get(Calendar.YEAR); int month = calendar.get(Calendar.MONTH); int day = calendar.get(Calendar.DAY_OF_MONTH); // Create DatePickerDialog DatePickerDialog datePickerDialog = new DatePickerDialog(this, (view, selectedYear, selectedMonth, selectedDay) -> { // Handle the selected date }, year, month, day); // Set DatePicker to spinner mode datePickerDialog.getDatePicker().setCalendarViewShown(false); // Show the DatePickerDialog datePickerDialog.show(); } }

Explanation

  1. DatePickerDialog: Create a DatePickerDialog instance with the current date.
  2. Set Spinner Mode: Call setCalendarViewShown(false) on the DatePicker to enable spinner mode.
  3. Show Dialog: Finally, call show() to display the date picker dialog.

Summary

  • Use setCalendarViewShown(false) to switch to spinner mode.
  • This method effectively hides the calendar view, allowing only spinner controls to select the date.

This approach gives you a simple way to set up a spinner-style date picker programmatically in your Android application!
