Integration

The lib is available on Maven Central, you can find it with Gradle, please

dependencies {
    compile 'com.github.traex.expandablelayout:library:1.2.2'
}

Usage

ExpandableLayout

Declare an ExpandableLayout inside your XML layout file. You also need to other layouts for header and content:

  <com.andexert.expandablelayout.library.ExpandableLayout
         android:id="@+id/expandableLayout"
         xmlns:expandable="http://schemas.android.com/apk/res-auto"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         expandable:headerLayout="@layout/view_header"
         expandable:contentLayout="@layout/view_content"/>

ExpandableLayoutItem && ExpandableLayoutItem

You can use ExapandableLayout in an ExpandableLayoutListView with ExpandableLayoutItem as row :

ExpandableLayoutItem

  <com.andexert.expandablelayout.library.ExpandableLayoutItem
         android:id="@+id/expandableLayout"
         xmlns:expandable="http://schemas.android.com/apk/res-auto"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         expandable:headerLayout="@layout/view_header"
         expandable:contentLayout="@layout/view_content"/>

ExpandableLayoutListView

  <com.andexert.expandablelayout.library.ExpandableLayoutListView
         android:id="@+id/expandableLayout"
         xmlns:expandable="http://schemas.android.com/apk/res-auto"
         android:layout_width="match_parent"
         android:layout_height="match_parent"/>

If you want to manage the OnScroll, you have to use OnExpandableLayoutScrollListener and don't forget to call super in each method.

You can call dynamically open, close and isOpened from an ExpandableLayout object.

Customization

You can change duration of the animation:

  • app:duration [integer def:200] --> Duration of the animation

Troubleshooting

If you want to use the ExpandableLayoutListView with EditText, you have to set android:windowSoftInputMode="adjustPan" to prevent the ListView to redraw itself and close the ExpandableLayoutItem.

  • name headerLayout is generic and may conflict with navigation drawer implementation

    name headerLayout is generic and may conflict with navigation drawer implementation

    at least a few people have had the issue where they use a headerLayout as the name for the navigation drawer header layout, which causes generated build files to have conflicts here is one other example on stackoverflow I would suggest changing the name to something like fixedHeaderLayout for example

    if you add more items,for example,ten or twenty so that listview will hide some items,the bug will reappear.

  • added listener for events.

    added listener for events.

    I added code for observations.

    Some times, I need handling start and end of animations.

    Listener is used above.

        private ExpandableLayout expandableLayout;

    expandableLayout.setOnStartHidingListener(new ExpandableLayout.OnStartHidingListener() {
        @Override
        public void onHidingowing(ExpandableLayout layout) {

        }
    });

    expandableLayout.setOnStartShowingListener(new ExpandableLayout.OnStartShowingListener() {
        @Override
        public void onStartShowing(ExpandableLayout layout) {

        }
    });

    expandableLayout.setOnFinishHidingListener(new ExpandableLayout.OnFinishHidingListener() {
        @Override
        public void onFinishHiding(ExpandableLayout layout) {

        }
    });

    expandableLayout.setOnFinishShowingListener(new ExpandableLayout.OnFinishShowingListener() {
        @Override
        public void onFinishShowing(ExpandableLayout layout) {

        }
    });

    Typo and grammatical errors

    In the first paragraph, below the first picture diagram, the line is written as, " Both view are external layout to allow a maximum of customization." This line has some errors. The correct line could be, " Both views have an external layout to allow maximum customization.

    In the usage section, in the ExpandableLayout subheading, the line is written as, "You also need to other layouts for header and content:" The corrected line could be written as, " You also need other layouts for header and content:"

    Thank you.
