pinch

问题 I have a layout, which include some TextViews and ImageViews. Haven't they created an easy way to include pinch zoom on an simple ScrollView/LinearLayout? I have watched some codes, but they work only on ImageViews. Recently I found setDisplayZoomControls(boolean). Is it possible to make this work on a layout with TextViews? If no, maybe somebody provides a code, which will zoom in/out my layout with pinch zoom. Thanks. 回答1: Try using android-pinch, it is supposed to work on web-views as well

问题 I am trying to detect a pinch to zoom event on iOS (and Android really) because I am using jQuery Mobile to show pages with a fixed header. In a dream world what I'd like is for the header not to zoom but for the rest of the page to do so. But I know this is not possible. On most pages I have a mobile version that resizes itself nicely making zooming un-necessary, but on the 'front cover' the client wants the user to be able to see the whole page (shrunk to fit) with the fixed header large

Here's the gist of my code: var w = 800, h = 600; $('img').on('touchy-pinch', function (e, $target, data) { $(this).css({ width: w * data.scale, height: h * data.scale }); }); Where the custom data object contains the following: scale previousScale currentPoint startPoint startDistance It works fine on the first pinch, but once my fingers leave the screen and then I try to do

问题 I apologize for the newbie question : How do you implement the pinchzoom gesture in phonegap apps? I am just starting with PhoneGap and a little education wont hurt hehe ! Thnx! 回答1: My experience is that you don't implement it so much as you use it. Phonegap is essentially a webview (think mobile safari). So it does allow for automatic zooming gestures, but to implement it, you do so just as you would with any website (basically create web content that requires it, or utilize webkit calls

问题 I am trying to add pinch to zoom feature to a data bound ListBox. What is the most efficient way to do this? I have placed the ListBox inside a Grid control and made it scrollable.

问题 I'm trying to create a mobile-friendly web page that will allow a user to drag an <img> around in a <div> . I've got this working using the image.ontouchstart method. Now I want to make it so the user can pinch-to-zoom when viewing this from an iOS device (I'm currently browsing to my page locally from my iPad). From the research I've done so far, it seems like the way to go is to use the Google Maps Javascript API. My question is: It is possible to use the Google Maps Javascript API to

问题 I want to detect pinch event on an IFrame (Extjs 5 Component). What's wrong with this code?? Ext.create('Ext.ux.IFrame', { autoScroll: true, src: 'resources/docs/doc1.html', cls: 'iframeStyle', listeners: { pinch: function (event) { alert('event.scale= ' + event.scale); } } }) 回答1: Out of the box, Ext.ux.Iframe does not have "pinch" as an event. Only the events listed on the API can be added using the "listeners" syntax. http://docs.sencha.com/extjs/5.0/5.0.1-apidocs/#!/api/Ext.ux.IFrame You
