Program- 2) Swipe Listeners With Animations
Video is here http://youtu.be/zEM2S5VHESg
Using this Code you can Implement Left,Right,Top,Bottom SwipeListeners.
I implemented just Right Swipe Listener
Before we start the Building Swipe Listeners it is necessary to create animation code.
Create anim Folder in res folder of your Android Project and create the following xml files.
fade_back.xml: -
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<scale android:duration="300"
android:pivotX="50.0%"
android:pivotY="50.0%"
android:fromXScale="1.0"
android:toXScale="0.85"
android:fromYScale="1.0"
android:toYScale="0.85"/>
<alpha android:duration="300"
android:fromAlpha="1.0"
android:toAlpha="0.1"/>
</set>
fade_in.xml :-
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<scale android:duration="300"
android:pivotX="50.0%"
android:pivotY="50.0%"
android:fromXScale="0.85"
android:toXScale="1.0"
android:fromYScale="0.85"
android:toYScale="1.0"/>
<alpha android:duration="300"
android:fromAlpha="0.1"
android:toAlpha="1.0"/>
</set>
slide_in_left.xml :-
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="350"
android:fromXDelta="100.0%p"
android:toXDelta="0.0"/>
Slide_out_right:-
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="300"
android:fromXDelta="0.0"
android:toXDelta="100.0%p"/>
