Question

How to animate different set of objects in different time duration one after the other?

JAVA Code:

ImageButton home = (ImageButton)findViewById(R.id.homeicon);
ImageButton settings = (ImageButton)findViewById(R.id.settingsicon); 

Animation alpha_anim = AnimationUtils.loadAnimation(this, R.anim.alpha);
home.startAnimation(alpha_anim);
settings.startAnimation(alpha_anim);

Animation File:

<?xml version="1.0" encoding="utf-8"?>
<alpha
xmlns:android="http://schemas.android.com/apk/res/android"
android:fromAlpha="0.0"
android:toAlpha="0.9"
android:duration="8000" /> 

can anyone help me?

Answer 1

I had one screen where I need to animate first layout and as soon as its finish, I wanted to start animation on second layout.

So I had used handler at that time to do so, like this

Handler handler = new Handler(); // create Handler object
handler.post(homeRun);
Runnable homeRun = new Runnable() { // create runnable to start home anim
    public void run() {
        home.startAnimation(alpha_anim);
        handler.postDelayed(settingsRun, 1000); // start setting anim after the time the home takes to animate
    }
};

Runnable setingsRun = new Runnable() { // runnable to start settings anim
    public void run() {
        settings.startAnimation(alpha_anim);
    }
};
