Step 1. Add the JitPack repository to your build file

Add it in your root settings.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Add it in your settings.gradle.kts at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url = uri("https://jitpack.io") }
		}
	}

Add to pom.xml

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.Tsangares:ExpandableLayout:v1.5.1'
	}
	dependencies {
		implementation("com.github.Tsangares:ExpandableLayout:v1.5.1")
	}
	<dependency>
	    <groupId>com.github.Tsangares</groupId>
	    <artifactId>ExpandableLayout</artifactId>
	    <version>v1.5.1</version>
	</dependency>

                            
    libraryDependencies += "com.github.Tsangares" % "ExpandableLayout" % "v1.5.1"
        
        

                            
    :dependencies [[com.github.Tsangares/ExpandableLayout "v1.5.1"]]

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

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"

<com.github.aakira.expandablelayout.ExpandableRelativeLayout
    android:id="@+id/expandableLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:ael_expanded="false"
    app:ael_duration="500"
    app:ael_interpolator="bounce"
    app:ael_orientation="vertical">

    <TextView
        android:id="@+id/text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="sample" />
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/text"
        android:text="sample2" />
</com.github.aakira.expandablelayout.ExpandableRelativeLayout>

ExpandableLinearLayout

Usage

You should use the ExpandableLinearLayout if child views may change a size. For example, it gets and sets values from a server.

Code

ExpandableLinearLayout expandableLayout
 = (ExpandableLinearLayout) findViewById(R.id.expandableLayout);

child.setText("Sets text from a server");
expandableLayout.initLayout(true); // Recalculate size of children

The initLayout() is deprecated in v1.5.0.
The argument of isMaintain flag doesn't work.
I'll fix it in v1.5.1

ExpandableWeightLayout

Usage

You should use this layout if you want to use weight attributes at expandable layout.

Code

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"

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <View
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"/>

    <com.github.aakira.expandablelayout.ExpandableWeightLayout
        android:id="@+id/expandableLayout"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="3"
        app:ael_duration="1000"
        app:ael_interpolator="anticipateOvershoot">

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:src="@drawable/sample" />
    </com.github.aakira.expandablelayout.ExpandableWeightLayout>

    <View
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"/>
</LinearLayout>

Listener


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.

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

You can use interpolator. It helps the layout animates easily.

|Interpolator|value name of attribute | |:-:|:-:| |AccelerateDecelerateInterpolator|accelerateDecelerate| |AccelerateInterpolator|accelerate| |AnticipateInterpolator|anticipate| |AnticipateOvershootInterpolator|anticipateOvershoot| |BounceInterpolator|bounce| |DecelerateInterpolator|decelerate| |FastOutLinearInInterpolator|fastOutLinearIn| |FastOutSlowInInterpolator|fastOutSlowIn| |LinearInterpolator|linear| |LinearOutSlowInInterpolator|linearOutSlowIn| |OvershootInterpolator|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

buildscript {
	repositories {
		jcenter()
	}
}

dependencies {
	compile 'com.github.Tsangares:ExpandableLayout:7da6d0f9c6'
}
