To change Edittext’s underline color:

If you want the entire app to share this style, then you can do the following way.

(1) go to styles.xml file. Your AppTheme that inherits the parent of Theme.AppCompat.Light.DarkActionBar (in my case) will be the base parent of all they style files in your app. Change the name of it to “AppBaseTheme’. Make another style right under it that has the name of AppTheme and inherits from AppBaseTheme that you just edited. It will look like following:

<pre><code>&lt;!-- Base application theme. --&gt;
&lt;style name="AppBaseTheme" parent="Theme.AppCompat.Light.DarkActionBar"&gt;
 &lt;!-- Customize your theme here. --&gt;
 &lt;item name="windowActionBar"&gt;false&lt;/item&gt;
 &lt;!--see http://www.google.com/design/spec/style/color.html#color-color-palette--&gt;
 &lt;item name="colorPrimary"&gt;@color/material_brown_500&lt;/item&gt;
 &lt;item name="colorPrimaryDark"&gt;@color/material_brown_700&lt;/item&gt;
 &lt;item name="colorAccent"&gt;@color/flamingo&lt;/item&gt;

&lt;style name="AppTheme" parent="AppBaseTheme"&gt;
 &lt;!-- Customize your theme here. --&gt;
&lt;/style&gt;
</code></pre>

Then change the “colorAccent” to whatever the color you want your EditText line color to be. 

(2) If you have other values folders with style.xml, this step is very important. Because that file will inherit from your previous parent xml file. For example, I have values-19/styles.xml. This is specifically for Kitkat and above. Change its parent to AppBaseTheme and make sure to get rid of “colorAccent” so that it doesn’t override the parent’s color. Also you need to keep the items that are specific to version 19. Then it will look like this.

<pre><code>&lt;resources&gt;
 &lt;!-- Base application theme. --&gt;
 &lt;style name="AppTheme" parent="AppBaseTheme"&gt;
 &lt;item name="android:windowTranslucentStatus"&gt;true&lt;/item&gt;
 &lt;/style&gt;
&lt;/resources&gt;
</code></pre>

blocks|key|4599671|text|线条的颜色是由EditText的background属性定义的。要更改它，您应该更改布局文件中的android:background。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4599672|我应该注意到，这种风格是通过使用9补丁可绘制实现的。如果你查看SDK，你可以看到EditText的背景是这个图片：|4599673|​|4599674|📷|atomic|4599675|4599676|要更改它，您可以在图像处理程序中打开它，并将其着色为所需的颜色。将其另存为bg_edit_text.9.png，然后将其放入可绘制的文件夹中。现在，您可以将其作为EditText的背景应用，如下所示：|4599677|android:background="@drawable/bg_edit_text"|code-block|syntax|javascript|4599678|entityMap|0|IMAGE|mutability|IMMUTABLE|imageUrl|https://ask.qcloudimg.com/http-save/yehe-900000/e792af62f5a200532f2ded67c2f2c7ca.png|imageAlt^0|7|8|1C|I|0|14|8|0|0|0|1|0|0|0|11|I|29|8|0|0^^$0|@$1|2|3|4|5|6|7|13|8|@$9|14|A|15|B|C]|$9|16|A|17|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|18|8|@$9|19|A|1A|B|C]]|D|@]|E|$]]|$1|H|3|I|5|6|7|1B|8|@]|D|@]|E|$]]|$1|J|3|K|5|L|7|1C|8|@]|D|@$9|1D|A|1E|1|1F]]|E|$]]|$1|M|3|I|5|6|7|1G|8|@]|D|@]|E|$]]|$1|N|3|O|5|6|7|1H|8|@$9|1I|A|1J|B|C]|$9|1K|A|1L|B|C]]|D|@]|E|$]]|$1|P|3|Q|5|R|7|1M|8|@]|D|@]|E|$S|T]]|$1|U|3|-4|5|6|7|1N|8|@]|D|@]|E|$]]]|V|$W|$5|X|Y|Z|E|$10|11|12|-4]]]]

The line's color is defined by <code>EditText</code>'s background property. To change it you should change the <code>android:background</code> in the layout file.

I should note that this style is achieved by using a 9-patch drawable. If you look in the SDK, you can see that the background of the <code>EditText</code> is this image:

<img src="https://i.stack.imgur.com/OeM7E.png" alt="textfield_activated_holo_light.9.png">

To change it you could open it in an image manipulation program and color it in desired color. Save it as <code>bg_edit_text.9.png</code> and then put it in you drawable folder. Now you can apply it as a background for your <code>EditText</code> like so:

<pre><code>android:background="@drawable/bg_edit_text"
</code></pre>

If you want a flat line, you can do this easily with xml. Here is the xml example:

<pre><code>&lt;layer-list xmlns:android="http://schemas.android.com/apk/res/android"&gt;
 &lt;item
 android:top="-1dp"
 android:left="-1dp"
 android:right="-1dp"
 android:bottom="1dp"
 &gt;
 &lt;shape android:shape="rectangle"&gt;
 &lt;stroke android:width="1dp" android:color="#6A9A3A"/&gt;
 &lt;/shape&gt;
 &lt;/item&gt;
&lt;/layer-list&gt;
</code></pre>

Replace the shape with a selector if you want to provide different width and color for focused edittext.

blocks|key|93694|text|最好的方法是使用具有app名称空间的backgroundTint属性的AppCompatEditText。即|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|93695|++++<android.support.v7.widget.AppCompatEditText

The best approach is to use an <code>AppCompatEditText</code> with <code>backgroundTint</code> attribute of <code>app</code> namespace. i.e.

<pre><code> &lt;android.support.v7.widget.AppCompatEditText
 android:layout_width="match_parent" 
 app:backgroundTint="YOUR COLOR"
 android:layout_height="wrap_content" /&gt;
</code></pre>

when we use <code>android:backgroundTint</code> it will only work in API21 or more but <code>app:backgroundTint</code> works on all API levels your app does.

You can do it dynamically if you have custom class for edittext.
First of all you have declare state and color of edittext given below.
<pre><code>int[][] states = new int[][]{
 new int[]{-android.R.attr.state_focused}, // enabled
 new int[]{android.R.attr.state_focused}, // disabled
 };
 int[] colors = new int[]{
 secondaryColor,
 primaryColor,
 };
</code></pre>
Then Create ColorStateList variable with that
<pre><code>ColorStateList myList = new ColorStateList(states, colors);
</code></pre>
Then last step is to assign it to edittext.
<pre><code>editText.setBackgroundTintList(myList);
</code></pre>
After this you have to written on focused change event.
<pre><code>this.setOnFocusChangeListener(new OnFocusChangeListener() {
 @Override
 public void onFocusChange(View view, boolean b) {
 setUnderlineColor(selectionColor,deselectionColor);
 }
 });
</code></pre>
And you can make above code inside setUnderlineClor() Method,
<pre><code>private void setUnderlineColor(int primaryColor, int secondaryColor) {
 if (Build.VERSION.SDK_INT &gt;= Build.VERSION_CODES.LOLLIPOP) {
 int[][] states = new int[][]{
 new int[]{-android.R.attr.state_focused}, // enabled
 new int[]{android.R.attr.state_focused}, // disabled
 };
 int[] colors = new int[]{
 secondaryColor,
 primaryColor,
 };
 ColorStateList myList = new ColorStateList(states, colors);
 setBackgroundTintList(myList);
 }
}
</code></pre>

blocks|key|4599688|text|对该edittext使用android:background属性。将您的可绘制文件夹图像传递给它。例如,|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4599689|android:background="@drawable/abc.png"|code-block|syntax|javascript|4599690|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Use android:background property for that edittext. Pass your drawable folder image to it.

Try the following way, it will convert the bottom line color of EditText, when used as a background property.

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;layer-list xmlns:android="http://schemas.android.com/apk/res/android"&gt;
 &lt;item
 android:left="@dimen/spacing_neg"
 android:right="@dimen/spacing_neg"
 android:top="@dimen/spacing_neg"&gt;
 &lt;shape&gt;
 &lt;solid android:color="@android:color/transparent" /&gt;
 &lt;stroke
 android:width="@dimen/spacing_1"
 android:color="@android:color/black" /&gt;
 &lt;/shape&gt;
 &lt;/item&gt;
&lt;/layer-list&gt;
</code></pre>

in xml layout use:
<pre><code>android:backgroundTint=&quot;@color/colorPrimary&quot;
</code></pre>
or in java code copy this method:
<pre><code>public void changeLineColorInEditText(EditText editText, int color) {
 editText.setBackgroundTintList(ColorStateList.valueOf(color));
 }
</code></pre>
and use it like this:
<pre><code>changeLineColorInEditText(editText, getResources().getColor(R.color.colorPrimary));
</code></pre>

blocks|key|4599954|text|只需将此android:theme="@style/AppTheme.AppBarOverlay作为editText的属性包含在中，并将此<style+name="AppTheme.AppBarOverlay"+parent="ThemeOverlay.AppCompat.Dark.ActionBar"+/>添加到样式中，即可完成此操作|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4599955|entityMap^0|4|18|1X|2E|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

This can simply be done by including this <code>android:theme="@style/AppTheme.AppBarOverlay</code> as attribute in for your editText
and add this <code>&lt;style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" /&gt;</code> to your styles
