ElasticDragDismissLayout

Standard ViewGroups which responds to nested scrolls to create drag-dismissable layouts. Original code taken from Plaid and made backwards compatible.

Gradle Dependency

Add this in your root build.gradle file (not your module build.gradle file):

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

Then, add the library to your project build.gradle

dependencies {
    implementation 'com.github.Commit451:ElasticDragDismissLayout:1.0.4'
}

Usage

See the sample project for a full example. Within XML:

<com.commit451.elasticdragdismisslayout.ElasticDragDismissLinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/draggable_frame"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    app:dragDismissDistance="112dp"
    app:dragDismissScale="0.95">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="#993F51B5" />

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerview"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</com.commit451.elasticdragdismisslayout.ElasticDragDismissLinearLayout>

In addition, you will probably want to have your new activity have a theme that allows for transparency. See styles.xml for an example.

To allow for dismiss:

mDraggableFrame.addListener(new ElasticDragDismissListener() {
        @Override
        public void onDrag(float elasticOffset, float elasticOffsetPixels, float rawOffset, float rawOffsetPixels) {}

        @Override
        public void onDragDismissed() {
            //if you are targeting 21+ you might want to finish after transition
            finish();
        }
    });

Supported ScrollViews

  • ScrollView (if 21+ and android:nestedScrollingEnabled="true")
  • RecyclerView
  • NestedScrollView (from support v4 library)

Currently Created Elastic Views

  • ElasticDragDismissFrameLayout
  • ElasticDragDismissLinearLayout
  • ElasticDragDismissRelativeLayout

You can create your own by using the ElasticDragDismissDelegate and using one of the created views as a reference.
