为什么我的EditText在Android中将Width和Height设置为wrap_content后水平或垂直展开？

[英]Why does my EditText got expanded horizontally or vertically after setting Width and Height as wrap_content in android?

问题描述

I'm newbie to android. 我是android的新手。 So I'm struggling with the following problem. 所以我正在努力解决以下问题。

1.after set android:layout_width = "wrap_content" in EditText, it got expanded vertically. 1.在EditText中设置android:layout_width = "wrap_content"之后，它被垂直扩展。

2.after set android:layout_width="180dp" in EditText, it got expanded horizontally. 2.在EditText中设置android:layout_width="180dp"后，它被水平扩展。

Is there anyway to set my EditText fixed? 有没有设置我的EditText固定？ Ex: If am going to type a long email address in EditText, font size of the text should get shrinked based on long text instead of EditText getting expanded. 例如：如果要在EditText中键入长电子邮件地址，则文本的字体大小应基于长文本而不是EditText进行扩展而缩小。 is there any possibility to achieve this task? 有没有可能完成这项任务？

I have used your XML and modified it. 我已经使用了你的XML并对其进行了修改。 Just add your images. 只需添加图片即可。 I removed it as I wasn't having them. 我删除了它，因为我没有它们。

EDIT : I have added android:inputType for editTexts as well + and put a limit on phone number (12) and email (20), you can change them according to yourself. 编辑 ：我已经添加了android:inputType for editTexts +并限制了电话号码（12）和电子邮件（20），你可以根据自己改变它们。

Setting the following property on the TextView fixed this weird issue for me. 在TextView上设置以下属性为我修复了这个奇怪的问题。 This should be the default behaviour of the textview in my opinion. 在我看来，这应该是textview的默认行为。 

android:imeOptions="flagNoExtractUi"

在Libraries For Developers中，您将在StackOverflow中找到多个AutoScaleTextView变体和几个代码片段来实现此目的（如果我理解正确的话）
