Webview pinch to zoom

[Heather]

Hello all,

I have a scene with a webview in it that won't zoom in or out. It's made of a direct HTML code that consists primarily of an <img> tag. I tried adding the following meta tag with no success.

<meta name="viewport" content="width=device-width, initial-scale=.5, maximum-scale=12.0, minimum-scale=.25, user-scalable=yes"/>

Any ideas?

What happens if you remove the additional scaling,

<meta name="viewport" content="initial-scale=1.0, user-scalable=yes, width=device-width" />

What version of Android are you testing on?

There is no change in the lack of ability to zoom in the scene's webview. Also, if the html code is simply in an .html document and opened in Chrome, with either meta code or even no meta code at all, I can pinch to zoom. It's just in the Tasker scene webview that it doesn't work.

I'm using Android  version 4.4.2.

Its not clear to me how Tasker has zoom implemented in webview. To enable zoom functions you can use the scene action, element web control, show zoom controls at which point pinch to zoom becomes available but with visible zoom controls too.

[Heather]

Yuck I was hoping to avoid the visible controls. I wonder why this is the case for webview, as in why doesn't it behave like the traditional browser? Strange.

[Sean Williams]

Maybe its due to an older implementation, wasnt pinch to zoom added to android?

[Heather]

No idea. Is this something Pent might be able to update?

[Sean Williams]

Maybe with setDisplayZoomControls

What I have noticed is google are putting an emphasis on web development which could make controling things in webview even more useful in future.

[Heather]

I found this, which includes the setDisplayZoomControls, but it appears that it will likely be something Pent has to change in Tasker. Unless there is a way I can incorporate some code into the direct HTML source of the webview to override what Tasker currently has set up. Is this possible?

[Matt R]

It seems like it's controlled by android and not something that could be modified with JavaScript or HTML code. I think it requires a "hide zoom controls" action that's the corollary of the current "show zoom controls" action in scene > element web control.
