NestedScrollWebView for Android

A WebView that implements NestedScrollingChild, in order to use it with CoordinatorLayout and AppBarLayout from the Android Design Support Library. This is necessary since embedding a regular WebView in a NestedScrollView causes height issues (e.g. infinite height, tested with design:23.1.1).

This is just a workaround, until Google will hopefully fix it.

The code is based on this and this.

Setup Instructions

(1) Using gradle

• Add the JitPack repository to your root build.gradle at the end of repositories:

allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}

• In your application's main module (usually called "app"), edit your build.gradle to add a new dependency:

dependencies {
    implementation 'com.github.rhlff:NestedScrollWebView:v1.1.1'
}

(2) Using git submodule

• In the root of your application's project add the library as a git submodule:

git submodule add https://github.com/rhlff/NestedScrollWebView

• In the root of your application's project edit the file "settings.gradle" and add the following lines:

include ':NestedScrollWebView:lib'
project(':NestedScrollWebView').projectDir = new File('/NestedScrollWebView')

• In your application's main module (usually called "app"), edit your build.gradle to add a new dependency:

 dependencies {
    ...
    compile project(':NestedScrollWebView:lib')
 }

Now your project is ready to use this library.

To update the library, follow these steps:

• From the root of your application's project change directory to the library:

cd NestedScrollWebView

• Pull the last changes:

git pull origin master

Now the library is up to date.

Usage

In your layout.xml include the following:

<com.tobiasrohloff.view.NestedScrollWebView
            android:id="@+id/webView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:focusable="true"
            android:focusableInTouchMode="true"
            app:layout_behavior="@string/appbar_scrolling_view_behavior" />

Known Issues

Doesn't work well with CollapsingToolbarLayout, mainly tested with the regular ToolbarLayout.
