Note that we are going to implement this project using the Java language.

Step by Step Implementation

Step 1: Create a New Project

To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. Note that select Java as the programming language.

Step 2: Add dependency and JitPack Repository

Navigate to the Gradle Scripts > build.gradle(Module:app) and add the below dependency in the dependencies section.   

implementation ‘com.github.niwattep:material-slide-date-picker:v2.0.0’

Add the JitPack repository to your build file. Add it to your root build.gradle at the end of repositories inside the allprojects{ } section.

allprojects {

 repositories {

   …

   maven { url “https://jitpack.io” }

     }

}

After adding this dependency sync your project and now we will move towards its implementation.  

Step 3: Create a new Slider Date Picker in your activity_main.xml file

Navigate to the app > res > layout > activity_main.xml and add the below code to that file. Below is the code for the activity_main.xml file. 

XML

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical"
    tools:context=".MainActivity">

    <!--Text View to display Date-->
    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="Text View" />

    <!--Button to select date-->
    <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/textView"
        android:text="SELECT" />

</RelativeLayout>

Step 4: Working with the MainActivity.java file

Go to the MainActivity.java file and refer to the following code. Below is the code for the MainActivity.java file. Comments are added inside the code to understand the code in more detail.

Java

import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

import androidx.appcompat.app.AppCompatActivity;

import com.niwattep.materialslidedatepicker.SlideDatePickerDialog;
import com.niwattep.materialslidedatepicker.SlideDatePickerDialogCallback;

import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Locale;

public class MainActivity extends AppCompatActivity implements SlideDatePickerDialogCallback {

    // Initialize textview and button
    Button button;
    TextView textView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // button and text view called using id
        button = findViewById(R.id.button);
        textView = findViewById(R.id.textView);

        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Calendar endDate = Calendar.getInstance();
                endDate.set(Calendar.YEAR, 2100);
                SlideDatePickerDialog.Builder builder = new SlideDatePickerDialog.Builder();
                builder.setEndDate(endDate);
                SlideDatePickerDialog dialog = builder.build();
                dialog.show(getSupportFragmentManager(), "Dialog");
            }
        });
    }

    // date picker
    @Override
    public void onPositiveClick(int date, int month, int year, Calendar calendar) {
        SimpleDateFormat format = new SimpleDateFormat("EEEE, MMM dd, yyyy", Locale.getDefault());
        textView.setText(format.format(calendar.getTime()));
    }
}

Now click on the run option it will take some time to build Gradle. After that, you will get output on your device as given below.

Output:
