关于DJI Pilot应用中Zoom Slider Widget的技术咨询：无法在官方文档中找到对应控件信息

Hey there, I’ve been down this road before while working on custom drone applications with DJI’s SDKs. That zoom slider you spotted in DJI Pilot is actually an internal, unofficially documented UI component that DJI reserves for their first-party apps like Pilot and GO 4.

Here’s what I’ve picked up from developer communities and hands-on testing:

• It’s not exposed in the official DJI Mobile SDK (Android/iOS) public APIs or documentation. DJI keeps many of their polished, app-specific UI elements private to maintain consistency across their own products.
• To replicate this functionality in your own app, you’ll need to build a custom slider component from scratch. The core logic will hook into the camera’s zoom controls using the official SDK’s methods:
  • For Android: Use the CameraZoomManager class to handle zoom actions. Link your custom slider’s position changes to methods like setZoomRatio() or startZoom() to adjust the camera’s zoom level in real time.
  • For iOS: Utilize DJICamera methods such as setZoomFactor:withCompletion: or startZoomWithDirection:velocity: to sync your slider’s input with the camera’s zoom functionality.
• A number of third-party developer resources have shared open-source custom zoom sliders built specifically for DJI apps. These examples typically sync the slider’s position with live camera zoom ratio updates, which can serve as a solid starting point.

If you can share more details about your target platform (Android/iOS) or specific feature requirements, I can offer more tailored advice on building and integrating your custom zoom slider!

Important note: Since this component isn’t officially supported by DJI, any workaround relying on reverse-engineered code might break with future SDK updates. Building your own custom slider is the most reliable long-term solution.
