Android Drag Dismiss Activity

Another implementation of the drag-to-dismiss Activity pattern. This one is inspired by Nick Butcher's Plaid implementation.

The project has a simple API and is a pretty powerful and beautiful implementation of the pattern. This library is used in some of my apps (Talon for Twitter and Pulse SMS). It has been abstracted from Jacob Klinker and I's article-android library, which is an awesome readability style in-app web browser.

This library provides an elastic layout that can dismiss an Activity with a RecyclerView or a regular Activity. Whenever the user swipes up or down, from the bottom or the top of the content, the DragDismissActivity will finish.

Including It In Your Project


This project was designed to be very easy to implement on top of your existing Activities.

To include it in your project, add this to your module's build.gradle file:

dependencies {
	compile 'com.klinkerapps:drag-dismiss-activity:1.7.0'

Note: The normal way to implement the drag-dismiss functionality is by extending the two provided Activities: DragDismissActivity and DragDismissRecyclerViewActivity. If you would rather not do that, I have provided a delegate for each of these use-cases, that you can use: DragDismissDelegate and DragDismissRecyclerViewDelegate. To see an example of the delegate's usage, check out the AbstractDragDismissActivity.

Replacing an Activity

This library is meant to replace your AppCompatActivity. I will set up all the drag-dismiss features for you, and wrap your content in a boilerplate UI that contains a Toolbar and a ScrollView for your content.

DragDismissActivity is easy to implement:

  1. Within your AndroidManifest.xml, on your activity elements replace whatever theme you are currently using with android:theme="@style/DragDismissTheme.
  2. Instead of extending AppCompatActivity, extend the DragDismissActivity.
  3. You won't want to override Activity#onCreate. Instead, override DragDismissActivity#onCreateContent. This method acts a bit like Fragment#onCreateView:
protected View onCreateContent(LayoutInflater inflater, ViewGroup parent, Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.activity_scrollable, parent, false);

    // do your normal view setup and Activity#onCreate lifecycle actions here,
    // instead of within the Activity#onCreate.

    return v;

For a very simple example, please see DismissableActivityNormalContent Sample.

Replacing an Activity with a RecyclerView

If you are using an Activity that just has a RecyclerView in it, then this library can do all the heavy-lifting for you, all you will need to do is set it up with a RecyclerView.Adapter and a LayoutManager.

DragDismissRecyclerViewActivity is easy to implement as well:

  1. Within your AndroidManifest.xml, on your activity elements replace whatever theme you are currently using with android:theme="@style/DragDismissTheme.
  2. Instead of extending AppCompatActivity, extend the DragDismissRecyclerViewActivity.
  3. You won't want to override Activity#onCreate. Instead, to set up your RecyclerView, override DragDismissRecyclerViewActivity#setupRecyclerView:
protected void setupRecyclerView(RecyclerView recyclerView) {
    recyclerView.setLayoutManager(new LinearLayoutManager(this));
    recyclerView.setAdapter(new SampleAdapter());

    // do any other RecyclerView or Activity setup that needs to be done

For a very simple example, please see DismissableActivityRecyclerView Sample.

Customizing the Boilerplate UI

After implementing the steps above, you will get your old Activity, with drag-to-dismiss functionality at the top and the bottom of the layout, great! You probably want to customize it further though.

I have provided a DragDismissBundleBuilder that allows you to add customization to the DragDismissActivity through extras on an Intent:

Intent dragDismissActivity = new Intent(this, MyDragDismissActivity.class);

new DragDismissBundleBuilder(context)
    .setTheme(DragDismissBundleBuilder.Theme.LIGHT)	// LIGHT (default), DARK, BLACK, DAY_NIGHT, SYSTEM_DEFAULT
    .setPrimaryColorResource(R.color.colorPrimary)	// defaults to a semi-transparent black
    .setToolbarTitle("Normal Activity Sample")		// defaults to null
    .setShowToolbar(true)				// defaults to true
    .setShouldScrollToolbar(true)       // defaults to true
    .setFullscreenOnTablets(false)      // defaults to false, tablets will have padding on each side
    .setDragElasticity(DragDismissIntentBuilder.DragElasticity.NORMAL)  // Larger elasticities will make it easier to dismiss.
    .setDrawUnderStatusBar(false)       // defaults to false. Change to true if you don't want me to handle the content margin for the Activity. Does not apply to the RecyclerView Activities

// do anything else that you want to set up the Intent
// dragDismissActivity.putBoolean("test_bool", true);


Adding a ProgressBar

Have content that won't be loaded immediately? No problem.

While content is loading, you can call DragDismissActivity#showProgessBar to automatically show the progress indicator. When the content is done loading, just call DragDismissActivity#hideProgessBar to remove it.

For a simple example usage, check out the DismissableActivityNormalContent sample.
