Shimmer Effect is one of the most popular features that we see in most Android apps. We can get to see this Shimmer Effect while loading the screen in animated form. Using Shimmer Effect in the Android app makes a good User Experience. In this article, we are going to see how to implement the Shimmer Effect in the Android app. A sample GIF is given below to get an idea about what we are going to do in this article. Note that we are going to implement this project using the Java language.
Applications of Shimmer Effect
- Shimmer Effect is mostly used for loading the screen in an attractive form.
- Shimmer Effect gives a good appearance to Images in the Android app.
- Using Shimmer Effect in our app gives an Animated view of the image.
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 of Shimmer Effect library in build.gradle file
Then Navigate to gradle scripts and then to build.gradle(Module) level. Add below line in build.gradle file in the dependencies section.
implementation ‘com.facebook.shimmer:shimmer:0.5.0’
now click on Sync now it will sync your all files in build.gradle().
Step 3: Create a new Shimmer Effect 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 android:layout_width = "match_parent" android:layout_height = "match_parent" android:background = "@color/black" android:paddingLeft = "16dp" android:paddingTop = "16dp" android:paddingRight = "16dp" android:paddingBottom = "16dp" tools:context = ".MainActivity" > <!--Shimmer Effect--> < com.facebook.shimmer.ShimmerFrameLayout android:id = "@+id/shimmer_view_container" android:layout_width = "wrap_content" android:layout_height = "wrap_content" android:layout_centerInParent = "true" > < LinearLayout android:layout_width = "wrap_content" android:layout_height = "wrap_content" android:gravity = "center" android:orientation = "vertical" > <!--Image--> < ImageView android:layout_width = "150dp" android:layout_height = "150dp" android:src = "@drawable/ic_baseline_account_balance_24" /> <!--Text given to Image--> < TextView android:layout_width = "wrap_content" android:layout_height = "wrap_content" android:layout_marginTop = "35dp" android:text = "Bank" android:textColor = "@color/purple_200" android:textSize = "24dp" android:textStyle = "bold" /> </ LinearLayout > </ com.facebook.shimmer.ShimmerFrameLayout > <!--Button1 to start Shimmer Effect--> < Button android:id = "@+id/button" android:layout_width = "wrap_content" android:layout_height = "wrap_content" android:layout_alignParentStart = "true" android:layout_alignParentLeft = "true" android:layout_alignParentBottom = "true" android:paddingLeft = "20dp" android:text = "Start" /> <!--Button2 to stop Shimmer Effect--> < Button android:id = "@+id/button2" android:layout_width = "wrap_content" android:layout_height = "wrap_content" android:layout_alignParentEnd = "true" android:layout_alignParentRight = "true" android:layout_alignParentBottom = "true" android:paddingRight = "20dp" android:text = "Stop" /> </ 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 androidx.appcompat.app.AppCompatActivity; import com.facebook.shimmer.ShimmerFrameLayout; public class MainActivity extends AppCompatActivity { // Variables created for buttons and Shimmer Button button1, button2; ShimmerFrameLayout container; @Override protected void onCreate(Bundle savedInstanceState) { super .onCreate(savedInstanceState); setContentView(R.layout.activity_main); button1 = findViewById(R.id.button); button2 = findViewById(R.id.button2); // Button 1 to start Shimmer Effect button1.setOnClickListener( new View.OnClickListener() { @Override public void onClick(View v) { // If auto-start is set to false container.startShimmer(); } }); // Button 2 to stop Shimmer Effect button2.setOnClickListener( new View.OnClickListener() { @Override public void onClick(View v) { // If auto-start is set to false container.stopShimmer(); } }); // Shimmer effect container = (ShimmerFrameLayout) findViewById(R.id.shimmer_view_container); } } |
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.
