Sketchware Pro से Advanced Age Calculator App कैसे बनाएं



Aaj is tutorial mein aap seekhenge ki kaise Sketchware Pro ka use karke ek Advanced Age Calculator App banaya jaye — jisme User ki age sirf Year hi nahi, balki Month, Week, Day, Hour, Minute, Second tak calculate hoti ho.

📁 Step 1: Create New Project in Sketchware Pro

Apne mobile mein Sketchware Pro open karein aur ek naya project create karein. Uske baad:

  • Top-right corner mein diye gaye three dots (⋮) par tap karein
  • Java/Kotlin Manager open karein
  • Wahan ek

    MainActivity.java

     file create karein

🧠 Step 2: Add Java Code

Ab aapko niche diya gaya Java code apne

MainActivity.java

 mein paste karna hai.
Note: Package name ko apne project ke package name se replace zarur karein.

      package com.my.newproject2pkg;

import android.app.Activity;
import android.app.DatePickerDialog;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.LinearLayout;
import android.widget.TextView;
import android.widget.Toast;

import java.util.Calendar;

public class MainActivity extends Activity {

    private TextView tvDate, tvResult;
    private Button btnPick, btnCalculate;
    private LinearLayout resultCard;

    private Calendar dobCalendar = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main); // ensure XML ka naam yahi hai

        // Views Initialization
        tvDate = findViewById(R.id.tv_date);
        tvResult = findViewById(R.id.tv_result);
        btnPick = findViewById(R.id.btn_pick);
        btnCalculate = findViewById(R.id.btn_calculate);
        resultCard = findViewById(R.id.result_card);

        // Shuru mein result card invisible rakhen
        resultCard.setVisibility(View.GONE);

        btnPick.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                openDatePicker();
            }
        });

        btnCalculate.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                calculateAge();
            }
        });
    }

    private void openDatePicker() {
        final Calendar today = Calendar.getInstance();

        int year = today.get(Calendar.YEAR);
        int month = today.get(Calendar.MONTH);
        int day = today.get(Calendar.DAY_OF_MONTH);

        DatePickerDialog picker = new DatePickerDialog(MainActivity.this,
                new DatePickerDialog.OnDateSetListener() {
                    @Override
                    public void onDateSet(DatePicker datePicker, int y, int m, int d) {
                        dobCalendar = Calendar.getInstance();
                        dobCalendar.set(y, m, d);
                        // Display selected date
                        String dateStr = String.format("%02d / %02d / %d", d, m + 1, y);
                        tvDate.setText(dateStr);
                        // Hide previous result (if any)
                        resultCard.setVisibility(View.GONE);
                        tvResult.setText("");
                    }
                }, year, month, day);

        picker.show();
    }

    private void calculateAge() {
        if (dobCalendar == null) {
            Toast.makeText(this, "पहले जन्मतिथि चुनें", Toast.LENGTH_SHORT).show();
            return;
        }

        Calendar today = Calendar.getInstance();

        if (dobCalendar.after(today)) {
            Toast.makeText(this, "भविष्य की तारीख मान्य नहीं है!", Toast.LENGTH_SHORT).show();
            return;
        }

        int years = today.get(Calendar.YEAR) - dobCalendar.get(Calendar.YEAR);
        int months = today.get(Calendar.MONTH) - dobCalendar.get(Calendar.MONTH);
        int days = today.get(Calendar.DAY_OF_MONTH) - dobCalendar.get(Calendar.DAY_OF_MONTH);

        if (days < 0) {
            months--;
            days += today.getActualMaximum(Calendar.DAY_OF_MONTH);
        }

        if (months < 0) {
            years--;
            months += 12;
        }

        // Detailed age in days, hours, minutes, seconds
        long diffMillis = today.getTimeInMillis() - dobCalendar.getTimeInMillis();
        long diffSeconds = diffMillis / 1000;
        long diffMinutes = diffSeconds / 60;
        long diffHours = diffMinutes / 60;
        long diffDays = diffHours / 24;
        long diffWeeks = diffDays / 7;

        String resultText = "आपकी उम्र:\n\n"
                + "🎂 वर्षों में: " + years + "\n"
                + "📅 महीनों में: " + months + "\n"
                + "📆 दिनों में: " + days + "\n"
                + "🗓️ सप्ताहों में: " + diffWeeks + "\n"
                + "⏳ घंटों में: " + diffHours + "\n"
                + "⏰ मिनटों में: " + diffMinutes + "\n"
                + "⏲️ सेकंडों में: " + diffSeconds;

        tvResult.setText(resultText);
        resultCard.setVisibility(View.VISIBLE);
    }
}




🎨 Step 3: Add Layout File (main.xml)

Java code save karne ke baad, ab aapko layout file create karni hai:

  • Java/Kotlin Manager ke neeche Resource section par tap karein
  • Uske baad Layout mein jaakar ek new XML file banayein

  • File ka naam hona chahiye: main.xml

📄 XML Code:

      <ScrollView
	xmlns:android="http://schemas.android.com/apk/res/android"
	xmlns:app="http://schemas.android.com/apk/res-auto"

				<Button

					android:layout_height="wrap_content"
					android:text="Pick"
					android:textSize="12sp"
					android:textColor="#FFFFFF"
					android:backgroundTint="#FF4081"
					android:layout_marginStart="12dp" />
			</LinearLayout>
		</LinearLayout>
		<Button
			android:id="@+id/btn_calculate"
			android:layout_width="match_parent"
			android:layout_height="wrap_content"
			android:layout_marginTop="10dp"
			android:layout_marginBottom="20dp"
			android:text="Calculate Age"
			android:textSize="18sp"
			android:textColor="#FFFFFF"
			android:backgroundTint="#3F51B5"
			android:radius="12dp" />
		<LinearLayout
			android:id="@+id/result_card"
			android:layout_width="match_parent"
			android:layout_height="wrap_content"
			android:padding="16dp"
			android:background="#FFFFFF"
			android:orientation="vertical"
			android:elevation="4dp"
			android:radius="12dp">
			<TextView
				android:id="@+id/tv_result"
				android:layout_width="match_parent"
				android:layout_height="wrap_content"
				android:gravity="center_horizontal|center_vertical"
				android:text="Your Age Will Be Shown Here"
				android:textSize="16sp"
				android:textColor="#333333" />
		</LinearLayout>
	</LinearLayout>
</ScrollView>


📲 Final Output:

Jab aap app ko run karenge, user apni Date of Birth enter karega aur app uski age dikhayega in this format:

  • Years: 23
  • Months: 280
  • Weeks: 1212
  • Days: 8484
  • Hours: 203616
  • Minutes: 12216960
  • Seconds: 732897600
