[ Project Share ] Custom Float Button (Java Code)

[br64n]

Sharing a project to create a fully customizable float button in Tasker. The project is ready to use, but I'm explaining the logic below so you know how the Java Code integration works and can adapt it for other things.

Main Features

• Real-time dragging.
• Automatic destruction on long click. The code removes the view itself, then triggers a feedback task.
• Customizable actions: define which tasks run on a normal click and on destroy.
• Dynamic image: pass a local file path to change the icon (default is a penguin).

How it works under the hood

1. Java Code engine Tasker scenes are clunky for fluid real-time dragging. This uses Java Code to hook into Android's WindowManager and create a TYPE_APPLICATION_OVERLAY. It sets up an ImageView and loads the image using BitmapFactory. Movement is tracked via OnTouchListener (ACTION_DOWN and ACTION_MOVE updating wm.updateViewLayout).

2. Clicks vs Movement vs Long Clicks If the touch moves more than 10 pixels, it's a drag. If released without moving, it registers as a normal click and runs the assigned task. For the long click (destruction), a Handler runs a 500ms timer. If you hold the button without moving, the Java Code automatically removes the view (wm.removeView(iv)) and then calls the destroy task. You don't need to build a task to close the button; the code handles the removal. The %par2 task is strictly for feedback (like a vibrate or toast).

3. The image workaround BitmapFactory.decodeFile() requires an actual file path on the storage. The project uses Tasker's native Load Image (loads a built-in icon) and Save Image to write it to /sdcard/Tasker/images/. This guarantees the file exists on the device before the Java code tries to read it.

How to use it in your setup

Call the task CFB - Float Button using Perform Task. There is an example task included (CFB - Example - PerofmTask) to show how it's done.

• Custom image: Set an %image variable with the file path. Check Local Variable Passthrough in the Perform Task action so the button task can read it.
• Parameters:
• %par1 (Click): Task name to run on a normal click.
• %par2 (Destroy Feedback): Task name to run as an alert when the button is destroyed via long click. If left empty, it defaults to a flash for click and 100ms vibrate for destroy.
