Dynamic Swipe View | Swipe View Demo in Android | Swipe through Touch Gesture


Hi Friends,

I am going to explore my first  sample application in android ,which gives you
an idea , How to create a Dynamic swipe view in Android.

Hope this will helps you......


1- Print Screen of Dynamic Swipe View


2-Android Manifest file
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="swip.view.example"
    android:versionCode="1"
    android:versionName="1.0" >
    <uses-sdk android:minSdkVersion="8" />
    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

4-Main.xml file

<ViewFlipper xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/flipper"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >
</ViewFlipper>

5-And create a folder name "anim" in res and add 4 xml file for left, right up, down swipe on touch screen.
i)res/anim/slide_in_left.xml
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromXDelta="-50%p" android:toXDelta="0"
            android:duration="@android:integer/config_mediumAnimTime"/>
<alpha android:fromAlpha="0.0" android:toAlpha="1.0"
            android:duration="@android:integer/config_mediumAnimTime" />
</set>

ii)res/anim/slide_in_right.xml
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromXDelta="50%p" android:toXDelta="0"
            android:duration="@android:integer/config_mediumAnimTime"/>
<alpha android:fromAlpha="0.0" android:toAlpha="1.0"
            android:duration="@android:integer/config_mediumAnimTime" />
</set>

iii)res/anim/slide_out_left.xml
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromXDelta="0" android:toXDelta="-50%p"
            android:duration="@android:integer/config_mediumAnimTime"/>
<alpha android:fromAlpha="1.0" android:toAlpha="0.0"
            android:duration="@android:integer/config_mediumAnimTime" />
</set>

iv)res/anim/slide_out_right.xml
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromXDelta="0" android:toXDelta="50%p"
            android:duration="@android:integer/config_mediumAnimTime"/>
<alpha android:fromAlpha="1.0" android:toAlpha="0.0"
            android:duration="@android:integer/config_mediumAnimTime" />
