Step 3: Create a new Balloon View in your activity_main.xml

Go to the activity_main.xml file and refer to the following code. Below is the code for the activity_main.xml file.

XML




<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

        android:layout_centerInParent="true"
        android:text="Button"
        android:textSize="15dp"
        android:textStyle="bold" />
      
</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.os.Handler;
import android.view.View;
import android.widget.Button;
  
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.content.ContextCompat;
  
import com.skydoves.balloon.ArrowOrientation;

import com.skydoves.balloon.BalloonAnimation;
  
public class MainActivity extends AppCompatActivity {
  
    Button button;
    Balloon balloon;
  
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
  
        // Id for the button
        button = findViewById(R.id.button);
  
        // Balloon view created here
        balloon = new Balloon.Builder(getApplicationContext())
                .setArrowSize(10)
                .setArrowOrientation(ArrowOrientation.TOP)
                .setIsVisibleArrow(true)
                .setArrowPosition(0.3f)
                .setWidthRatio(0.6f)
                .setHeight(65)
                .setTextSize(15f)
                .setCornerRadius(4f)

                .setTextColor(ContextCompat.getColor(getApplicationContext(), R.color.design_default_color_secondary))
                .setBackgroundColor(ContextCompat.getColor(getApplicationContext(), R.color.design_default_color_secondary_variant))
                .setBalloonAnimation(BalloonAnimation.FADE)
                .build();
          
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                balloon.showAlignBottom(button);
                new Handler().postDelayed(new Runnable() {
                    @Override
