不建议使用OnCameraChangeListener()

今天，回顾我的旧代码，我发现 OnCameraChangeListener()现在已被弃用.

Today, looking back at my old code, I've found out that OnCameraChangeListener() is now deprecated.

我发现很难理解如何修复我的这段代码:

I'm finding difficult to understand how to fix this piece of code of mine:

mGoogleMap.setOnCameraChangeListener(new GoogleMap.OnCameraChangeListener() { @Override public void onCameraChange(CameraPosition cameraPosition) { // Cleaning all the markers. if (mGoogleMap != null) { mGoogleMap.clear(); } mPosition = cameraPosition.target; mZoom = cameraPosition.zoom; if (mTimerIsRunning) { mDragTimer.cancel(); } mDragTimer.start(); mTimerIsRunning = true; } });

新的侦听器(aka OnCameraMoveListener())方法 onCameraMove()没有 CameraPosition cameraPosition 输入变量，所以我我很迷路:有没有办法回收我的旧代码?

The new listener (aka OnCameraMoveListener()) method onCameraMove() doesn't have a CameraPosition cameraPosition input variable, so I'm pretty lost: is there a way to recycle my old code?

此处是一些参考

推荐答案

在 play-services-maps 9.4.0版的API ，它们用三个摄像头监听器替换了GoogleMap.OnCameraChangeListener():

In play-services-maps 9.4.0 version of the API, They replaced GoogleMap.OnCameraChangeListener() with three camera listeners :

• GoogleMap.OnCameraMoveStartedListener
• GoogleMap.OnCameraMoveListener
• GoogleMap.OnCameraIdleListener

• GoogleMap.OnCameraMoveStartedListener
• GoogleMap.OnCameraMoveListener
• GoogleMap.OnCameraIdleListener

根据您的代码，我认为您需要像这样使用GoogleMap.OnCameraIdleListener和GoogleMap.OnCameraMoveStartedListener:

Based on your code, I think you need to use GoogleMap.OnCameraIdleListener and GoogleMap.OnCameraMoveStartedListener like this:

mGoogleMap.setOnCameraMoveStartedListener(new GoogleMap.OnCameraMoveStartedListener() { @Override public void onCameraMoveStarted(int i) { mDragTimer.start(); mTimerIsRunning = true; } }); mGoogleMap.setOnCameraIdleListener(new GoogleMap.OnCameraIdleListener() { @Override public void onCameraIdle() { // Cleaning all the markers. if (mGoogleMap != null) { mGoogleMap.clear(); } mPosition = mGoogleMap.getCameraPosition().target; mZoom = mGoogleMap.getCameraPosition().zoom; if (mTimerIsRunning) { mDragTimer.cancel(); } } });
