how to implement blink effect on the image transition between android activites

Question

Aryan Kumar · Answer

To implement a blink effect on the image transition between Android activities, you can use the following code:
Code snippet
public class MainActivity extends AppCompatActivity {
    private ImageView imageView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        imageView = findViewById(R.id.imageView);
        // Get the image from the first activity
        Bitmap image = BitmapFactory.decodeResource(getResources(), R.drawable.image);
        // Create a Transition object
        Transition transition = new Transition();
        // Set the transition duration
        transition.setDuration(1000);
        // Set the transition effect
        transition.setInterpolator(new AccelerateDecelerateInterpolator());
        // Set the transition image
        transition.addTarget(imageView);
        // Start the transition
        transition.start();
        // Start the second activity
        Intent intent = new Intent(this, SecondActivity.class);
        startActivity(intent);
    }
}
This code will first get the image from the first activity. Then, it will create a
Transition object and set its duration and interpolator. Next, it will set the
Transition object's image to the imageView. Finally, it will start the
Transition object and start the second activity.
The Transition object will cause the imageView to blink for 1000 milliseconds before starting the second activity.
To use this code, you need to add the following dependency to your project's 
build.gradle file:
Code snippet
dependencies {
    ...
    implementation 'androidx.transition:transition:1.4.1'
}
You also need to add the following code to your project's activity_main.xml file:
Code snippet
andlt;ImageView
    android:id="@+id/imageView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scaleType="centerCrop" />
This code will add an ImageView widget to the activity_main.xml file. The
ImageView widget will be used to display the image that is being blinked.
