在EditText上的光标控制 [英] Cursor control in EditText
问题描述
好吧,这是要我发疯。我还是一个新手(也许是白痴),但是这其中有把我手忙脚乱。
Ok, this is about to drive me nuts. I'm still a newbie (and maybe an idiot) but this one has had me running in circles.
我想实现通过软按钮(左,右,向上或向下)的EDITTEXT光标控制。从我的研究,它看起来像我需要像为moveUp(),moveLeft(),extendUp(Selection对象的方法)等,但它们都需要一个text.layout对象,我不知道如何得到一个。
I'm trying to implement cursor control in an editText via soft buttons (left, right, up down). From what I've researched, it looks like I need the methods in the Selection object like moveUp(), moveLeft(), extendUp() etc. but they all need a "text.layout" object and I don't know how to get one.
我在正确的轨道上吗?帮助?
Am I on the right track? Help?
推荐答案
这听起来像你想使用的 DynamicLayout 对象。 (它的 text.Layout 派生类中的一个,另外一个是< A HREF =http://developer.android.com/reference/android/text/StaticLayout.html相对=nofollow> StaticLayout 。)
It sounds like you want to use a DynamicLayout object. (It's one of the derived classes of text.Layout, another being StaticLayout.)
