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);
	}

}

or

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

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

}

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">

    ...
