In this tutorial how to perform Slide Animation in Tween Animation in Android is shown.
Points to Remember:
- For creating the slide.xml file you will have to first create anim folder under res folder.
- At the time of creating slide.xml file you can either select ‘scale’ or ‘set’ as Root Element.
Code:
activity_main.xml
<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=”.MainActivity” >
<ImageView
android:id=”@+id/imageView1″
android:layout_width=”wrap_content”
android:layout_height=”wrap_content”
android:layout_centerHorizontal=”true”
android:layout_centerVertical=”true”
android:src=”@drawable/tweenedanm” />
<Button
android:id=”@+id/b1″
android:layout_width=”wrap_content”
android:layout_height=”wrap_content”
android:layout_alignBottom=”@+id/imageView1″
android:layout_centerHorizontal=”true”
android:layout_marginBottom=”24dp”
android:onClick=”onSlide”
android:text=”Slide” />
</RelativeLayout>
res/anim/slide.xml
<?xml version=”1.0″ encoding=”utf-8″?>
<set
xmlns:android=”http://schemas.android.com/apk/res/android”
android:fillAfter=”true” >
<scale
android:duration=”500″
android:fromXScale=”1.0″
android:fromYScale=”1.0″
android:interpolator=”@android:anim/linear_interpolator”
android:toXScale=”1.0″
android:toYScale=”0.0″/>
</set>

public void onSlide(View v)
{
Animation animation=AnimationUtils.loadAnimation(getApplicationContext(), R.anim.slide);
iv.startAnimation(animation);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
//Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
