Using either property:

worked for me to hide the underline of the EditText.

However, do note that it then causes a spacing issue with the TextInputLayout that I've surrounding the <code>EditText</code>

I discovered the most curious thing! If you set it to <code>null</code> using Data Binding:
<code>android:background="@{null}"</code>

Then not only is the background removed, but the view still has the padding that was calculated from the default background. So for some reason the deferred null setting doesn't clear the padding from the previous bg..? The padding on the view is left/top/right 4dp, bottom 13dp (from emulator level 21).

May not have same end result on all API levels, so beware! Someone tell me if you test this and find it reliable. (Also note that that bottom padding sticks out because of that underline that was in the original. So you'll probably want to change it in the XML, or reset it in the code after it's loaded to equal top...

If you want this to affect all instances of EditText and any class that inherits from it, then you should set in your theme the value for the attribute, editTextBackground.

<pre><code> &lt;item name="android:editTextBackground"&gt;@drawable/bg_no_underline&lt;/item&gt;
</code></pre>

An example of the drawable I use is:

<pre><code>&lt;inset xmlns:android="http://schemas.android.com/apk/res/android"
 android:insetLeft="@dimen/abc_edit_text_inset_horizontal_material"
 android:insetRight="@dimen/abc_edit_text_inset_horizontal_material"
 android:insetTop="@dimen/abc_edit_text_inset_top_material"
 android:insetBottom="@dimen/abc_edit_text_inset_bottom_material"&gt;
 &lt;selector&gt;
 &lt;item android:drawable="@android:color/transparent"/&gt;
 &lt;/selector&gt;
&lt;/inset&gt;
</code></pre>

This is slightly modified version of what the default material design implementation is.

When applied it will make all your EditText remove the underline throughout the app, and you don't have to apply the style to each and every one manually.

I have something like this which is very very useful:

<pre><code>generalEditText.getBackground().mutate().setColorFilter(getResources().getColor(R.color.white), PorterDuff.Mode.SRC_ATOP);
</code></pre>

where generalEditText is my EditText and color white is:

<pre><code>&lt;color name="white"&gt;#ffffff&lt;/color&gt;
</code></pre>

This will not remove padding and your EditText will stay as is. Only the line at the bottom will be removed. Sometimes it is more useful to do it like this.

If you use <code>android:background="@null"</code> as many suggested you lose the padding and EditText becomes smaller. At least, it was my case.

A little side note is if you set background null and try the java code I provided above, your app will crash right after executing it. (because it gets the background but it is null.) It may be obvious but I think pointing it out is important.

An other option, you can create your own custom EditText like this :
<pre><code>class CustomEditText : androidx.appcompat.widget.AppCompatEditText {
 constructor(context: Context?) : super(context)
 constructor(context: Context?, attrs: AttributeSet?) : super(context, attrs)
 constructor(context: Context?, attrs: AttributeSet?, defStyleAttr: Int) : super(context, attrs, defStyleAttr)

 private val paint = Paint()
 private val path = Path()

 init { // hide your underbar
 this.setBackgroundResource(android.R.color.transparent)

 // other init stuff...
 }

 override fun onDraw(canvas: Canvas?) {
 super.onDraw(canvas)

 // draw your canvas...
 }
}
</code></pre>

How can I hide the EditText underbar (the prompt line with little serifs at the ends)?

Sometimes, however, I would like to use the same layout (simplifies other logic) to display the same data in a read-only manner. I want the presentation to be similar - it should have the same height and same font, but not have the underbar.

As a stop-gap measure, I'm going to implement this by removing the EditText and substituting a TextView. 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.

如何隐藏EditText底栏(提示行末尾有小衬线)？也许有一种更好的方法来做我想做的事情:我有一个带有EditText的布局。通常，在用户可以点击它并开始输入或编辑文本的地方，它显示得很好。但是，有时我希望使用相同的布局(简化其他逻辑)以只读方式显示相同的数据。我希望演示文稿是相似的-它应该有相同的高度和相同的字体，但...
