Shake Icons in Android as iPhone on Long Press

android, animation

Solution

May be you can make `shake.xml` in `anim` folder.

    <?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="100"
    android:fromDegrees="-5"
    android:pivotX="50%"
    android:pivotY="50%"
    android:repeatCount="infinite"
    android:repeatMode="reverse"
    android:toDegrees="5" />

Now use it in your method `animateDragged()` as

Animation animation=AnimationUtils.loadAnimation(this,R.anim.shake);
v.startAnimation(animation);

Problem

I'm implementing an App where I want to shake the icons as in iPhone occurs. How can I implement the same? I have attached the code of my animation here. Please suggest me any solution. I have tried the soln that is already specified on the stack overflow but its not working in my case. And this class is a non-activity class in which this animation set is written. ``` protected void animateDragged(){ View v = getChildAt(dragged); int x = getCoorFromIndex(dragged).x + childSize / 2, y = getCoorFromIndex(dragged).y + childSize / 2; int l = x - (3 * childSize / 4), t = y - (3 * childSize / 4); v.layout(l, t, l + (childSize * 3 / 2), t + (childSize * 3 / 2)); AnimationSet animSet = new AnimationSet(true); ScaleAnimation scale = new ScaleAnimation(.667f, 1, .667f, 1, childSize * 3 / 4, childSize * 3 / 4); scale.setDuration(animT); AlphaAnimation alpha = new AlphaAnimation(1, .5f); alpha.setDuration(animT); animSet.addAnimation(scale); animSet.addAnimation(alpha); animSet.setFillEnabled(true); animSet.setFillAfter(true); v.clearAnimation(); v.startAnimation(animSet); } ``` Thanks
