Android的捏和缩放图像的活动

Android的捏和缩放图像的活动

本文介绍了Android的捏和缩放图像的活动的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我有一组图像的ListView控件。在点击其中任何一个,被点击的图像上会出现一个新的活动,并在ImageView的活动的中心,也实在是可缩放的。问题是,当我放大它的收益放大也像移动拖放的形象。我应该消除图像的运动,应该只从活动的中心缩放。

I have a ListView with set of images. On clicking any of them, the clicked image will appear on a new activity and at the center of the activity in ImageView, also it is Zoomable. The Problem is when i zoom the image it gains Zoom but also moves like drag and drop. I should eliminate that movement of the image and should only be zoomable from the center of the activity.
