A layout that hide the header when the body is scrolled down and reveal it when the header is scrolled up

In your gradle "app" :

dependencies {
    compile 'com.vcaen:androidautohideheader:1.2'
}

In you xml, add the '''AutoHideHeaderLayout''' :

    <com.vcaen.androidautohideheader.AutoHideHeaderLayout
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/autohideview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:fixedIfChildSmall="false"
        app:fixed="false"/>

Then in your java code :

   AutoHideHeaderLayout view  = (AutoHideHeaderLayout) findViewById(R.id.autohideview);
   ListView listView = new ListView(this);
   view.setHeader(R.layout.header); // You can also set the View object
   view.setBodyView(listView);

You can add the children directly into the XML by adding them inside the AutoHideHeaderLayout :

<RelativeLayout 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"
                tools:context=".MainActivity">

    <com.vcaen.androidautohideheader.AutoHideHeaderLayout
        android:id="@+id/autohideview"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="100dp">

            <ImageView
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:scaleType="centerCrop"
                android:src="@drawable/bg"/>

        </RelativeLayout>

        <ScrollView
            android:layout_width="match_parent"
            android:layout_height="match_parent">

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

            </LinearLayout>
        </ScrollView>
    </com.vcaen.androidautohideheader.AutoHideHeaderLayout>

</RelativeLayout>

The following options are available :

• Fix the header

  Java

      autoHideHeaderLayout.setFixed(Boolean)

  XML

      app:fixed="true"

• Fix the header if the child is smaller than the view. Only works if the child has height set at wrap_content

  Java

      autoHideHeaderLayout.setFixedIfChildSmall(Boolean)

  XML

      app:fixedIfChildSmall="true"
