## Usage
### ExpandableRelativeLayout
#### Usage
The expandableRelativeLayout doesn't work if child views change a size.
You should use the ExpandableLinearLayout if there is a possibility.
#### Code
```java
ExpandableRelativeLayout expandableLayout
= (ExpandableRelativeLayout) findViewById(R.id.expandableLayout);
// toggle expand, collapse
expandableLayout.toggle();
// expand
expandableLayout.expand();
// collapse
expandableLayout.collapse();
// move position of child view
expandableLayout.moveChild(0);
// move optional position
expandableLayout.move(500);
// set base position which is close position
expandableLayout.setClosePosition(500);
```
#### Layout xml
add `xmlns:app="http://schemas.android.com/apk/res-auto"`
```xml
```
### ExpandableLinearLayout
#### Usage
You should use the ExpandableLinearLayout if child views may change a size.
For example, it gets and sets values from a server.
And you should use this in recycler view.
#### Code
```java
// resize expandable layout
ExpandableLinearLayout expandableLayout
= (ExpandableLinearLayout) findViewById(R.id.expandableLayout);
child.setText("Sets text from a server");
expandableLayout.initLayout(); // Recalculate size of children
// recycler view
// you must set a ViewHolder#setIsRecyclable(false) and ExpandableLinearLayout#setInRecyclerView(true)
@Override
public void onBindViewHolder(final ViewHolder holder, final int position) {
holder.setIsRecyclable(false);
holder.expandableLinearLayout.setInRecyclerView(true);
}
```
### ExpandableWeightLayout
#### Usage
You should use this layout if you want to use weight attributes at expandable layout.
#### Code
```java
ExpandableWeightLayout expandableLayout
= (ExpandableWeightLayout) findViewById(R.id.expandableLayout);
// toggle expand, collapse
expandableLayout.toggle();
// expand
expandableLayout.expand();
// collapse
expandableLayout.collapse();
```
#### Layout xml
add `xmlns:app="http://schemas.android.com/apk/res-auto"`
```xml
```
### Listener
```java
expandableLayout.setListener(new ExpandableLayoutListener() {
@Override
public void onAnimationStart() {
}
@Override
public void onAnimationEnd() {
}
// You can get notification that your expandable layout is going to open or close.
// So, you can set the animation synchronized with expanding animation.
@Override
public void onPreOpen() {
}
@Override
public void onPreClose() {
}
@Override
public void onOpened() {
}
@Override
public void onClosed() {
}
});
```
* `ExpandableLayoutListenerAdapter`
- You can set listeners only you need.
```java
expandableLayout.setListener(new ExpandableLayoutListenerAdapter() {
@Override
public void onPreOpen() {
}
@Override
public void onPreClose() {
}
});
```
### Attributes
|attribute name|description|
|:-:|:-:|
|ael_duration|The length of the expand or collapse animation|
|ael_expanded|The layout is expanded if you set true|
|ael_defaultChildIndex|The layout is expanded at index of child view. (Only `ExpandableRelativeLayout`)|
|ael_defaultPosition|The layout is expanded at the position. (Only `ExpandableRelativeLayout`)|
|ael_orientation|The orientation of animation(horizontal \| vertical)|
|ael_interpolator|Sets [interpolator](#interpolator)|
### Interpolator
You can use [interpolator](http://developer.android.com/reference/android/view/animation/Interpolator.html).
It helps the layout animates easily.
|Interpolator|value name of attribute |
|:-:|:-:|
|[AccelerateDecelerateInterpolator](http://developer.android.com/reference/android/view/animation/AccelerateDecelerateInterpolator.html)|accelerateDecelerate|
|[AccelerateInterpolator](http://developer.android.com/reference/android/view/animation/AccelerateInterpolator.html)|accelerate|
|[AnticipateInterpolator](http://developer.android.com/reference/android/view/animation/AnticipateInterpolator.html)|anticipate|
|[AnticipateOvershootInterpolator](http://developer.android.com/reference/android/view/animation/AnticipateOvershootInterpolator.html)|anticipateOvershoot|
|[BounceInterpolator](http://developer.android.com/reference/android/view/animation/BounceInterpolator.html)|bounce|
|[DecelerateInterpolator](http://developer.android.com/reference/android/view/animation/DecelerateInterpolator.html)|decelerate|
|[FastOutLinearInInterpolator](http://developer.android.com/reference/android/support/v4/view/animation/FastOutLinearInInterpolator.html)|fastOutLinearIn|
|[FastOutSlowInInterpolator](http://developer.android.com/reference/android/support/v4/view/animation/FastOutSlowInInterpolator.html)|fastOutSlowIn|
|[LinearInterpolator](http://developer.android.com/reference/android/view/animation/LinearInterpolator.html)|linear|
|[LinearOutSlowInInterpolator](http://developer.android.com/reference/android/support/v4/view/animation/LinearOutSlowInInterpolator.html)|linearOutSlowIn|
|[OvershootInterpolator](http://developer.android.com/reference/android/view/animation/OvershootInterpolator.html)|overshoot|
These are support interpolator.
But a case that the expandable layout extends outside doesn't work.
e.g. AnticipateInterpolator, AnticipateOvershootInterpolator, OvershootInterpolator
I recommend you use such a interpolator for child views in the expandable layout.
* Not support
- CycleInterpolator
- PathInterpolator
## Setup
### Gradle
Add the dependency in your `build.gradle`
```groovy
buildscript {
repositories {
jcenter()
}
}
dependencies {
compile 'com.github.aakira:expandable-layout:1.6.0@aar'
}
```
