Rotate the image in both clockwise and anti-clockwise direction in Android (animation)
In this article, we are going to set animation on an image view by rotating the given image in both clockwise and anti-clockwise direction in Android.
Submitted by Manu Jemini, on February 01, 2018
In the example below, we are going to use the Animation.Animation class to create animation. This AnimationUtils.loadAnimation will create an object which can be used to create the animation for the image.
To implement this in your program you will need to import: android.view.animation.Animation, android.view.animation.AnimationUtils in your java file. Then create a layout file with a single button in the center and an ImageView.
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/imageView"
android:src="@drawable/includehelp"
android:layout_marginBottom="200dp" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Clockwise"
android:id="@+id/button"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="89dp"
android:onClick="rotate"/>
We will make another XML file with name of rotate.xml which will used to provide the data about the rotation along the relative axis.
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="0"
android:toDegrees="360"
android:pivotX="50%"
android:pivotY="50%"
android:duration="5000" >
</rotate>
The Object of the Animation class will be used on the image: image.startAnimation(animation1);
1) Java file:
package com.example.hp.myapplication;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
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);
}
public void rotate(View view){
ImageView image = (ImageView)findViewById(R.id.imageView);
Animation animation = AnimationUtils.loadAnimation(getApplicationContext(),
R.anim.rotate);
image.startAnimation(animation);
}
}
2) XML file:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.example.hp.myapplication.MainActivity">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/imageView"
android:src="@drawable/includehelp"
android:layout_marginBottom="200dp" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Clockwise"
android:id="@+id/button"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="89dp"
android:onClick="rotate"/>
</RelativeLayout>
3) Manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.hp.myapplication">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
4) rotate.xml file:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="0"
android:toDegrees="360"
android:pivotX="50%"
android:pivotY="50%"
android:duration="5000" >
</rotate>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:startOffset="5000"
android:fromDegrees="360"
android:toDegrees="0"
android:pivotX="50%"
android:pivotY="50%"
android:duration="5000" >
</rotate>
</set>
Output
