I spent a lot of time to search on the web a class which allows to create a rotation effect on each item of an Android listview.

Here is a good implementation which works fine :

package com.frisbeeeapp.frisbeee.utilities;

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapShader;
import android.graphics.Canvas;

import android.graphics.drawable.BitmapDrawable;

    private int borderWidth = 2;

Android listview: Create 3D rotation effect for listview item

I spent a lot of time to search on the web a class which allows to create a rotation effect on each item of an Android listview.

Here is a good implementation which works fine :

import android.view.View;
import android.view.animation.Animation;
import android.view.animation.Transformation;
import android.graphics.Camera;
import android.graphics.Matrix;

/**
 * An animation that rotates the view on the Y axis between two specified angles.
 * This animation also adds a translation on the Z axis (depth) to improve the effect.
 */
public class Rotate3dAnimation extends Animation {
    private final float mFromDegrees;
    private final float mToDegrees;
    private final float mDepthZ;
    private final View mView;
    private final boolean mReverse;
    private Camera mCamera;

    /**
     * Creates a new 3D rotation on the Y axis. The rotation is defined by its
     * start angle and

Android listview: Animate listview item like Google plus effect

There a few weeks ago when I was working on Android “Cup of News” application, I wanted to replicate the effect “Google Plus” on the various items contained in a listview.

From my point of view, the use of such effects must do this sparingly. Everything depends on the content in each item that makes up your listview.

I have long sought a solution that is adequate but after some research on the web, I came to a rather acceptable solution.

Create a global variable which will be used to store the last item position the listview :

private int lastPosition = -1 ;

Create the first animation file: up_from_bottom.xml :

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="@android:anim/decelerate_interpolator">
    <translate
        android:fromXDelta="0%" android:toXDelta="0%"
