ExpandableHeightListView

Android Library to put a ListView inside a ScrollView without collapsing.

How to use

Add this to your build.gradle:

repositories {

  mavenCentral() 
}
  dependencies {

compile 'com.github.paolorotolo:expandableheightlistview:1.0.0' 
}

Add ExpandableHeightListView instead of ListView in your xml files:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  android:layout_width="match_parent"
  android:layout_height="match_parent">

 <com.github.paolorotolo.expandableheightlistview.ExpandableHeightListView

 android:id="@+id/expandable_listview"

 android:layout_width="fill_parent"

 android:layout_height="wrap_content"

 android:padding="8dp">

</com.github.paolorotolo.expandableheightlistview.ExpandableHeightListView> </ScrollView>

Expand ExpandableHeightListView programmatically:

 ExpandableHeightListView expandableListView = (ExpandableHeightListView) findViewById(R.id.expandable_listview);

 expandableListView.setAdapter(adapterName);

// This actually does the magic
  expandableListView.setExpanded(true);

It also works well with GridView.

Just use this instead:

<com.github.paolorotolo.expandableheightlistview.ExpandableHeightGridView

 android:id="@+id/expandable_listview"

 android:layout_width="fill_parent"

 android:layout_height="wrap_content"

 android:padding="8dp">

</com.github.paolorotolo.expandableheightlistview.ExpandableHeightGridView>
