How to check if animation is running before starting new animation

In this android programming source code example, we are going to check to see if animation is running before starting new animation.

You can copy and adopt this source code example to your android project without reinventing the wheel.

Below is a step by step source code to check to see if animation is running before starting new animation.

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    android:orientation="vertical" xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".animation.Animation13">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Check Animation Status"
        android:layout_gravity="center_horizontal"
        android:textSize="20sp"/>

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/image"
        android:src="@drawable/notebook"/>

</LinearLayout>

MainActivity.java

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;

public class Animation13 extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_animation13);

        final Animation animation = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.rotation);
        final Animation animation2 = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.translate);
        final ImageView imageView = findViewById(R.id.image);

        animation.setAnimationListener(new Animation.AnimationListener() {
            @Override
            public void onAnimationStart(Animation animation) {
                Toast.makeText(getApplicationContext(), "First animation running", Toast.LENGTH_LONG).show();

            }

            @Override
            public void onAnimationEnd(Animation animation) {
                Toast.makeText(getApplicationContext(), "First Animation has end, starting second animation now", Toast.LENGTH_LONG).show();
                imageView.startAnimation(animation2);

            }

            @Override
            public void onAnimationRepeat(Animation animation) {

            }
        });
        imageView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                imageView.startAnimation(animation);
            }
        });
    }
}

anim/rotation.xml

<?xml version="1.0" encoding="utf-8"?>

anim/translate.xml

<?xml version="1.0" encoding="utf-8"?>
