Many times in android applications we have to capture the current date and time within our android application so that we can update our date according to that. In this article, we will take a look at How to get the current Time and Date in our android application.
Note: This Android article covered in both Java and Kotlin languages.
Step by Step Implementation
Step 1: Create a New Project in Android Studio
To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio.
Step 2: Working with the activity_main.xml file
Navigate to app > res > layout > activity_main.xml and add the code below. Comments are added in the code to get to know in detail.
XML
<?xml version="1.0" encoding="utf-8"?><RelativeLayout android:id="@+id/idRLContainer" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context=".MainActivity"> <!--on below line we are creating a text for our app--> <TextView android:id="@+id/idTVHeading" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_above="@id/idTVCurrent" android:layout_centerInParent="true" android:layout_margin="20dp" android:gravity="center" android:padding="10dp" android:text="Current Date and Time in Android" android:textAlignment="center" android:textColor="@color/black" android:textSize="20sp" android:textStyle="bold" /> <!--on below line we are creating a text view--> <TextView android:id="@+id/idTVCurrent" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_centerInParent="true" android:layout_margin="20dp" android:gravity="center" android:padding="10dp" android:text="Time" android:textAlignment="center" android:textColor="@color/black" android:textSize="20sp" android:textStyle="bold" /> </RelativeLayout> |
Step 3: Working with the MainActivity file
Navigate to app > java > your app’s package name > MainActivity file and add the below code to it. Comments are added in the code to get to know in detail.
Kotlin
package com.gtappdevelopers.kotlingfgproject import android.os.Bundleimport android.widget.TextViewimport androidx.appcompat.app.AppCompatActivityimport java.text.SimpleDateFormatimport java.util.* class MainActivity : AppCompatActivity() { // on below line we are creating a variable. lateinit var currentTV: TextView override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) // on below line we are initializing our variables. currentTV = findViewById(R.id.idTVCurrent) // on below line we are creating and initializing // variable for simple date format. val sdf = SimpleDateFormat("'Date\n'dd-MM-yyyy '\n\nand\n\nTime\n'HH:mm:ss z") // on below line we are creating a variable for // current date and time and calling a simple // date format in it. val currentDateAndTime = sdf.format(Date()) // on below line we are setting current // date and time to our text view. currentTV.text = currentDateAndTime }} |
Java
package com.gtappdevelopers.kotlingfgproject; import android.os.Bundle;import android.widget.TextView;import androidx.appcompat.app.AppCompatActivity;import java.text.SimpleDateFormat;import java.util.Date; public class MainActivity extends AppCompatActivity { // on below line we are creating variables. private TextView currentTV; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // on below line we are initializing our variables. currentTV = findViewById(R.id.idTVCurrent); // on below line we are creating and initializing // variable for simple date format. SimpleDateFormat sdf = new SimpleDateFormat("'Date\n'dd-MM-yyyy '\n\nand\n\nTime\n'HH:mm:ss z"); // on below line we are creating a variable // for current date and time and calling a simple date format in it. String currentDateAndTime = sdf.format(new Date()); // on below line we are setting current // date and time to our text view. currentTV.setText(currentDateAndTime); }} |
Now run your application to see the output of it.
Output:
