Flip View Example
Tip: set target to 4.0.3 +
This example shows how you can flip and animate a list view.
Algorithm:
1.) Create a new project by File-> New -> Android Project name it FlipViewExample.
2.) Write following into your main.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:id="@+id/button"
android:text="Flip"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<ListView
android:id="@+id/list_en"
android:layout_width="match_parent"
android:layout_weight="1.0"
android:layout_height="0dip"/>
<ListView
android:id="@+id/list_fr"
android:layout_width="match_parent"
android:layout_weight="1.0"
android:layout_height="0dip"
android:visibility="gone"/>
</LinearLayout>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:id="@+id/button"
android:text="Flip"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<ListView
android:id="@+id/list_en"
android:layout_width="match_parent"
android:layout_weight="1.0"
android:layout_height="0dip"/>
<ListView
android:id="@+id/list_fr"
android:layout_width="match_parent"
android:layout_weight="1.0"
android:layout_height="0dip"
android:visibility="gone"/>
</LinearLayout>
3.) Run for output.
Steps:
1.) Create a project named FlipViewExample and set the information as stated in the image.
Build Target: Android 4.0
Application Name: FlipViewExample
Package Name: example. FlipViewExample
Activity Name: FlipViewExample
Min SDK Version: 14
Application Name: FlipViewExample
Package Name: example. FlipViewExample
Activity Name: FlipViewExample
Min SDK Version: 14
2.) Open FlipViewExample.java file and write following code there:
