ExpandableRelativeLayout

Code

ExpandableRelativeLayout expandLayout
 = (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:defaultVisibility="false"
    app:duration="500"
    app:interpolator="bounce"
    app: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>

ExpandableWeightLayout

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

Code

ExpandableWeightLayout expandLayout
 = (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:duration="1000"
        app: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() {

    }

    @Override
    public void onOpened() {

    }

    @Override
    public void onClosed() {

    }
});

Attributes

attribute name	description
duration	The length of the expand or collapse animation
defaultVisibility	The layout is expanded at first if you set true
orientation	The orientation of animation(horizontal | vertical)
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.aakira:expandable-layout:1.0.1@aar'
}
