How can i get the current scale of a webView(android)

问题

getScale () was deprecated in API level 17. so , how can i get the current scale of a webview. i tried to override the method onScaleChanged, but it won`t be called unless i change the scale...

回答1:

I know this question is a bit old, but this may help someone (like me), especially if someone wants to override WebView and add onTouch listener, to detect WebView's content end.

You can use:

getResources().getDisplayMetrics().density

instead of

webView.getScale()

which is deprecated.

It is the same value, that represents screen density, compared to mdpi value. So, it will be as follows:

• ldpi: 0.75
• mdpi: 1.0
• hdpi: 1.5
• xhdpi: 2.0
• xxhdpi: 3.0
• xxxhdpi: 4.0

回答2:

WebView.getScaleX() and WebView.getScaleY() might help, is this what you want?

I don't have enough reputation to comment on your questions, so I'll just give an answer. Hope this helps (:
