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
