如何在EditText中隱藏下劃線

本文翻譯自：How to hide underbar in EditText

How can I hide the EditText underbar (the prompt line with little serifs at the ends)? 如何隱藏EditText底部欄（在提示行的末尾帶有小襯線）？

There might be a better way to do what I want: I have a layout with an EditText. 可能有一種更好的方式來做我想做的：我有一個帶有EditText的佈局。 Normally, this displays fine where the user can tap on it and begin entering or editing text. 通常，在用戶可以點擊它並開始輸入或編輯文本的地方，它顯示得很好。

Sometimes, however, I would like to use the same layout (simplifies other logic) to display the same data in a read-only manner. 但是，有時我想使用相同的佈局（簡化其他邏輯）以只讀方式顯示相同的數據。 I want the presentation to be similar - it should have the same height and same font, but not have the underbar. 我希望演示文稿是相似的-它應該具有相同的高度和相同的字體，但沒有下劃線。

As a stop-gap measure, I'm going to implement this by removing the EditText and substituting a TextView. 作爲權宜之計，我將通過刪除EditText並替換爲TextView來實現此目的。 I think that will give the desired results, but it seems like a roundabout an expensive way to do something that ought to be easy to do by changing attributes. 我認爲這可以達到預期的效果，但是似乎通過a迴繞是一種昂貴的方法，可以通過更改屬性來輕鬆完成某件事。

You can set the EditText to have a custom transparent drawable or just use 您可以將EditText設置爲具有自定義的透明可繪製對象，也可以僅使用

android:background="@android:color/transparent"

or 要麼

You can set EditText 's backgroundTint value to a specific color. 您可以將EditText的backgroundTint值設置爲特定顏色。 If you set transparent color, underbar should gone. 如果設置透明顏色，下劃線應消失。

android:backgroundTint="@color/Transparent"

<color name="Transparent">#00000000</color>

But you can use this in Api v21(Lollipop) or higher 但是您可以在Api v21(Lollipop)或更高版本中使用它

What I did was to create a Shape drawable and set that as the background: 我要做的是創建一個Shape繪製並將其設置爲背景：

<?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">

    <padding
        android:top="8dp"
        android:bottom="8dp"
        android:left="8dp"
        android:right="8dp" />

    <solid android:color="#fff" />

</shape>

Note: I actually used @dimen and @color values for the firelds, but I've simplified the shape file here for clarity. 注意：實際上，我爲firelds使用了@dimen和@color值，但是爲了清楚起見，我在這裏簡化了形狀文件。
