simple-view-behavior

Simple View Behavior for Android CoordinatorLayout.

This library provide you easy ways to config and setup the view behavior without creating subclass of Behavior

Installation

compile 'com.zoonref:simple-view-behavior:1.0'

Usage

You can setup behavior effect by using only xml option.

1. set the layout behavior to this library class app:layout_behavior="com.zoonref.SimpleViewBehavior"
2. set the dependency view by specify resource id by app:dependsOn="@+id/{your view id}"
3. set the type of dependency app:dependType="{x,y,width,height}"
4. set the dependency view target value according to the type you choose app:dependTargetXXX="{value}"
5. set the target appearance that you want your view to animate to

There are two ways to specify the animation when the dependency view changed.

1. xml

<View
        android:layout_width="40dp"
        android:layout_height="40dp"
        android:layout_marginTop="8dp"
        android:layout_marginLeft="20dp"
        android:rotationX="90"
        android:elevation="10dp"
        android:background="@android:color/holo_blue_bright"
        android:alpha="0"
        app:layout_behavior="com.zoonref.SimpleViewBehavior"
        app:dependsOn="@+id/app_bar"
        app:dependType="y"
        app:dependTargetY="-156dp"
        app:targetAlpha="1"
        app:targetRotateX="0"/>

This View will depend on the y positon of @+id/app_bar which is AppBarLayout. View will animation from current state of AppBarLayout until y position of AppBarLayout is -156dp with the animation, View will animate alpha to app:targetAlpha="1" rotate x to app:targetRotateX="0"

Don't forget to add xmlns:app="http://schemas.android.com/apk/res-auto"

The output will be

2. view animation resource file

When you use animation, all of animate target option from xml will be ignored.

for example

<View
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:layout_gravity="center|top"
        android:layout_marginTop="80dp"
        android:elevation="10dp"
        android:background="@android:color/holo_orange_dark"
        app:layout_behavior="com.zoonref.SimpleViewBehavior"
        app:dependsOn="@+id/app_bar"
        app:dependType="y"
        app:dependTargetY="-156dp"
        app:animation="@anim/rotate"/>

<set xmlns:android="http://schemas.android.com/apk/res/android">
    <scale
        android:duration="100"
        android:fromXScale="1"
        android:fromYScale="1"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toXScale="40dp"
        android:toYScale="40dp"/>
    <rotate
        android:duration="100"
        android:fromDegrees="0"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toDegrees="360"/>
    <alpha
        android:duration="100"
        android:toAlpha="0"/>
</set>

The output will be
