OverlayViewManager

OverlayViewManager is a lightweight Android library that allows you to overlay views on top of other apps, providing a simple interface to manage and customize these overlays. This library is particularly useful for creating floating widgets or overlays that need to be displayed across the entire system, regardless of the activity or app in the foreground.

Try out the sample application on Google Play.

Features

• Easy to Use: Simple API to create and manage overlay views.
• Customizable: Supports various customization options like touchable, draggable, and view positioning.
• Lifecycle Management: Manages the overlay view lifecycle based on activity or application context.
• Permission Handling: Provides methods to check and request overlay permissions.

Installation

Latest version:

Step 1. Add the JitPack repository to your build file

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Step 2. Add the dependency

dependencies {
    implementation 'com.github.75py.Android-OverlayViewManager:overlayviewmanager:{version}'
}

Usage

Initialization

Initialize the OverlayViewManager in your Application class:

public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        OverlayViewManager.init(this);
    }
}

Creating an Overlay View

To create an overlay view, use the OverlayViewManager to get an instance of OverlayView:

OverlayViewManager overlayViewManager = OverlayViewManager.getInstance();
TextView overlayTextView = new TextView(this);
overlayTextView.setText("Hello, World!");

OverlayView<TextView> overlayView = overlayViewManager.newOverlayView(overlayTextView);

Displaying the Overlay View

To display the overlay view, call the show method:

overlayView.show();

Hiding the Overlay View

To hide the overlay view, call the hide method:

overlayView.hide();

Customizing the Overlay View

You can customize various properties of the overlay view, such as its position, size, and touch behavior:

overlayView
    .setWidth(ViewGroup.LayoutParams.WRAP_CONTENT)
    .setHeight(ViewGroup.LayoutParams.WRAP_CONTENT)
    .setTouchable(true)
    .setDraggable(true)
    .setGravity(Gravity.TOP | Gravity.START)
    .setX(100)
    .setY(100)
    .setAlpha(0.8f);

Handling Permissions

To check if the app has overlay permissions, use the canDrawOverlays method:

if (!overlayViewManager.canDrawOverlays()) {
    // Request permission
    overlayViewManager.requestOverlayPermission();
}

To show a permission request dialog:

overlayViewManager.showPermissionRequestDialog(getSupportFragmentManager(), R.string.app_name);

Example

Here is a complete example of how to use the OverlayViewManager:

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Initialize OverlayViewManager
        OverlayViewManager.init(getApplication());

        // Create a new overlay view
        TextView overlayTextView = new TextView(this);
        overlayTextView.setText("Hello, Overlay!");

        OverlayView<TextView> overlayView = OverlayViewManager.getInstance().newOverlayView(overlayTextView);

        // Set properties
        overlayView
            .setWidth(ViewGroup.LayoutParams.WRAP_CONTENT)
            .setHeight(ViewGroup.LayoutParams.WRAP_CONTENT)
            .setTouchable(true)
            .setDraggable(true)
            .setGravity(Gravity.TOP | Gravity.START)
            .setX(100)
            .setY(100)
            .setAlpha(0.8f);

        // Show the overlay view
        overlayView.show();
    }
}
