How to set Horizontal flip animation in android

Let's see how to set Horizontal flip animation in android.

Create a xml file in anim folder. Then name it flip_h.

flip_h.xml

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"> <scale android:interpolator="@android:anim/accelerate_decelerate_interpolator" android:fromXScale="1.0" android:toXScale="-1.0" android:fromYScale="1.0" android:toYScale="1.0" android:pivotX="50%" android:pivotY="50%" android:duration="400" android:repeatMode="reverse" android:repeatCount="24" /> </set>

Xscale  is  horizontal . We want to animate it horizontally that's why set it from 1 to -1
Yscale is vertical.

We can reduce duration for fast and increase to load slowly.
repeatCount will repeat the animation as you set the value. Here I set it 24. As a result it will repeat 24 times.
duration  is the Amount of time for the animation to run which set in millisecond.






activity_main.xml

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.example.hp.symonapps.MainActivity" android:orientation="vertical" android:gravity="center"> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/iv" android:src="@drawable/ss2"/> </LinearLayout>

MainActivity.java

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

package com.example.hp.symonapps; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.animation.Animation; import android.view.animation.AnimationUtils; import android.widget.ImageView; public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ImageView iv=(ImageView)findViewById(R.id.iv); //cast the iv imageView button Animation anim=AnimationUtils.loadAnimation(MainActivity.this, R.anim.flip_h); iv.setAnimation(anim); } //onCreate end }
