Deprecated

This library is no longer supported as the modern convention of building Android apps switches from multi-Activity to single-Activity. If you are looking for similar behavior look into supporting Android's new predictive back handling

Slidr

Easily add slide-to-dismiss functionality to your Activity by calling Slidr.attach(this) in your onCreate(..) method.

Usage

An example usage:

public class ExampleActivity extends <Activity|FragmentActivity|ActionBarActivity> {

	@Override
	public void onCreate(Bundle savedInstanceState){
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_example);
		int primary = getResources().getColor(R.color.primaryDark);
		int secondary = getResources().getColor(R.color.secondaryDark);
		Slidr.attach(this, primary, secondary);
	}

}

public class ExampleActivity extends <Activity|FragmentActivity|ActionBarActivity> {

	@Override
	public void onCreate(Bundle savedInstanceState){
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_example);
        	Slidr.attach(this);
	}

}

Fragments

The activity must extend FragmentActivity. Set the background to the main container of the activity in the xml background="@android:color/transparent". Add the following code to the Fragment:

// This interface is needed to see if the fragment
// is resuming after creation (Slidr to be attached) or
// simply from the background (app was paused before).
SlidrInterface slidrInterface;

@Override
public void onResume() {
    super.onResume();
    if(slidrInterface == null)
        slidrInterface = Slidr.replace(getView().findViewById(R.id.content_container), new SlidrConfig.Builder().position(SlidrPosition.LEFT).build());
}

In the xml of the fragment's view, the root view must be a FrameLayout with the same background set to the activity before. Add a child viewgroup to it with the id content_container. E.g.:

<FrameLayout
    android:id="@+id/main_container"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/transparent">
    
    <android.support.design.widget.CoordinatorLayout
        android:id="@+id/content_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
	
		...other stuff

    </android.support.design.widget.CoordinatorLayout>
</FrameLayout>

Remember: you have to add new Fragments with:

getSupportFragmentManager().beginTransaction()
	.add(R.id.fragment_container, YourFragmentClass.newInstance())
	.commit();

where fragment_container is the id of a FrameLayout inside the activity's xml.

Configuring

SlidrConfig config = new SlidrConfig.Builder()
	.primaryColor(getResources().getColor(R.color.primary)
	.secondaryColor(getResources().getColor(R.color.secondary)
	.position(SlidrPosition.LEFT|RIGHT|TOP|BOTTOM|VERTICAL|HORIZONTAL)
	.sensitivity(1f)
	.scrimColor(Color.BLACK)
	.scrimStartAlpha(0.8f)
	.scrimEndAlpha(0f)
	.velocityThreshold(2400)
	.distanceThreshold(0.25f)
	.edge(true|false)
	.edgeSize(0.18f) // The % of the screen that counts as the edge, default 18%
	.listener(new SlidrListener(){...})
	.build();

Slidr.attach(this, config);

Slidr.attach(...) will return a SlidrInterface which gives you access to two methods:

SlidrInterface.lock();
SlidrInterface.unlock();

These methods lock or unlock the slidable touch interface.

The theme that you use for your sliding activity must have these attributes set:

<item name="android:windowIsTranslucent">true</item>  
<item name="android:windowBackground">@android:color/transparent</item>

Then in the layout of your activity you must give it a background like this;

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/background_material_light">

    ...
