This is how I do buttons only with a border and the ripple effect on Lollipop and above. Just like the AppCompat buttons, these have a fallback pressed effect on lower APIs (if you need ripples on lower APIs, you need to use an external library). I use FrameLayout because it's cheap. The color of the text and the border is black, but you can change it with a custom one:

<pre><code>&lt;FrameLayout
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:layout_margin="20dp"
 android:background="@drawable/background_button_ghost"&gt;

 &lt;TextView
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:background="?android:selectableItemBackground"
 android:gravity="center"
 android:padding="14dp"
 android:textSize="16sp"
 android:textAllCaps="true"
 android:textStyle="bold"
 android:textColor="@android:color/black"
 android:text="Text"/&gt;
&lt;/FrameLayout&gt;
</code></pre>

drawable/background_button_ghost.xml

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;shape xmlns:android="http://schemas.android.com/apk/res/android"&gt;
 &lt;stroke
 android:width="2dp"
 android:color="@android:color/black"/&gt;
 &lt;solid android:color="@color/transparent"/&gt;
&lt;/shape&gt;
</code></pre>

Simply you can use this code. Its looks soo Good.

<pre><code> &lt;LinearLayout
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:background="#ffffff"
 android:orientation="vertical"&gt;

 &lt;android.support.v7.widget.AppCompatButton
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:backgroundTint="#F48025"
 android:text="login"
 android:textColor="@color/colorWhite" /&gt;

 &lt;/LinearLayout&gt;
</code></pre>

Here border color is:

<pre><code>android:background="#ffffff"
</code></pre>

And background color is:

<pre><code>android:backgroundTint="#F48025"
</code></pre>

Here's how to do it correctly. 

What you need to do is

1 - Create shape drawable with stroke 
2 - Create ripple drawable 
3 - Create selector drawable for less than v21 
4 - Create a new style for button with border 
5 - Apply style on button 

1 - Create shape with stroke
<code>btn_outline.xml</code>

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

 &lt;stroke
 android:width="2dp"
 android:color="@color/colorAccent"&gt;
 &lt;/stroke&gt;
 &lt;solid android:color="@color/colorTransparent"/&gt;
 &lt;corners
 android:radius="5dp"&gt;
 &lt;/corners&gt;

&lt;/shape&gt;
</code></pre>

2 - Create ripple drawable
 <code>drawable-v21/bg_btn_outline.xml</code>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;ripple xmlns:android="http://schemas.android.com/apk/res/android"
 android:color="@color/colorOverlay"&gt;
 &lt;item&gt;
 &lt;shape&gt;
 &lt;stroke
 android:width="2dp"
 android:color="@color/colorAccent"/&gt;
 &lt;corners android:radius="5dp"/&gt;
 &lt;/shape&gt;
 &lt;/item&gt;
 &lt;item android:id="@android:id/mask"&gt;
 &lt;shape&gt;
 &lt;stroke
 android:width="2dp"
 android:color="@color/colorAccent"/&gt;
 &lt;solid android:color="@android:color/white"/&gt;
 &lt;corners android:radius="5dp"/&gt;
 &lt;/shape&gt;
 &lt;/item&gt;

&lt;/ripple&gt;
</code></pre>

<code>android:id="@android:id/mask"</code> is required to have ripple touch feedback on the button. The layer that is marked as mask is not visible on screen, its just for touch feedback. 

3 - Create selector drawable for less than v21 
<code>drawable/bg_btn_outline.xml</code>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;
 &lt;item android:drawable="@drawable/btn_outline" android:state_pressed="true"&gt;
 &lt;shape android:shape="rectangle"&gt;
 &lt;solid android:color="@color/colorOverlay"/&gt;
 &lt;/shape&gt;
 &lt;/item&gt;
 &lt;item android:drawable="@drawable/btn_outline" android:state_focused="true"&gt;
 &lt;shape android:shape="rectangle"&gt;
 &lt;solid android:color="@color/colorOverlay"/&gt;
 &lt;/shape&gt;
 &lt;/item&gt;

 &lt;item android:drawable="@drawable/btn_outline"/&gt;

&lt;/selector&gt;
</code></pre>

4 - Create a new style for button with border
 All resources that that are needed to create the style are given above, that's how your style should look like

<pre><code>&lt;style name="ButtonBorder" parent="Widget.AppCompat.Button.Colored"/&gt;

&lt;style name="ButtonBorder.Accent"&gt;
 &lt;item name="android:background"&gt;@drawable/bg_btn_outline&lt;/item&gt;
 &lt;item name="android:textColor"&gt;@color/colorAccent&lt;/item&gt;
 &lt;item name="android:textAllCaps"&gt;false&lt;/item&gt;
 &lt;item name="android:textSize"&gt;16sp&lt;/item&gt;
 &lt;item name="android:singleLine"&gt;true&lt;/item&gt;
 &lt;/style&gt;
</code></pre>

4 - Apply style on button

<pre><code>&lt;Button
 style="@style/ButtonBorder.Accent"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"/&gt;
</code></pre>

That's pretty much it. Here's a sample of how the buttons looks now.

You can also use the <a href="https://github.com/material-components/material-components-android" rel="nofollow noreferrer">Material Components for Android</a>.
Add <a href="https://github.com/material-components/material-components-android/blob/master/docs/getting-started.md" rel="nofollow noreferrer">the dependency</a> to your <code>build.gradle</code>:
<pre><code>dependencies { implementation 'com.google.android.material:material:1.3.0' }
</code></pre>
In this case you can use the <a href="https://github.com/material-components/material-components-android/blob/master/docs/components/MaterialButton.md" rel="nofollow noreferrer"><code>MaterialButton</code></a> in your layout file:
<pre><code>&lt;com.google.android.material.button.MaterialButton
 ....

</code></pre>
Apply the style <a href="http://@style/Widget.MaterialComponents.Button.OutlinedButton" rel="nofollow noreferrer"><code>@style/Widget.MaterialComponents.Button.OutlinedButton</code></a>.
In your case use the <code>app:cornerRadius</code> attribute to change the size of corner radius. This will round off the corners with specified dimensions. 
Use te attribute <code>app:strokeColor</code> and <code>app:strokeWidth</code> to change the color and the width of the border.

You can customize the button with these attributes:
<ul>
<li><code>app:backgroundTint</code>: Used to apply a tint to the background of the button. If you wish to change the background color of the button, use this attribute instead of background.
</li>
<li><code>app:strokeColor</code>: The color to be used for the button stroke

Credits to @NomanRafique for the detailed answer! However, because of the custom background, we've lost a few important things:
<ol>
<li>Button's height is bigger than the default <code>Widget.AppCompat.Button</code></li>
<li>Paddings</li>
<li>Enable/Disable states</li>
</ol>
In case you're wondering, here is how the default background looks like: <a href="https://android.googlesource.com/platform/frameworks/support/+/a7487e7/v7/appcompat/res/drawable-v21/abc_btn_colored_material.xml" rel="nofollow noreferrer">https://android.googlesource.com/platform/frameworks/support/+/a7487e7/v7/appcompat/res/drawable-v21/abc_btn_colored_material.xml</a>
By reusing original insets, paddings and color selectors, in a simple case we can come up with something like this (all the values are default and come from android support/material library) :
drawable-v21/bg_btn_outlined.xml

<pre class="lang-xml prettyprint-override"><code>&lt;inset xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
 android:insetLeft=&quot;@dimen/abc_button_inset_horizontal_material&quot;
 android:insetTop=&quot;@dimen/abc_button_inset_vertical_material&quot;
 android:insetRight=&quot;@dimen/abc_button_inset_horizontal_material&quot;
 android:insetBottom=&quot;@dimen/abc_button_inset_vertical_material&quot;&gt;
 &lt;ripple xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
 android:color=&quot;?attr/colorControlHighlight&quot;&gt;
 &lt;item&gt;
 &lt;shape&gt;
 &lt;stroke
 android:width=&quot;2dp&quot;
 android:color=&quot;@color/abc_btn_colored_borderless_text_material&quot;/&gt;
 &lt;corners android:radius=&quot;@dimen/abc_control_corner_material&quot;/&gt;
 &lt;padding
 android:bottom=&quot;@dimen/abc_button_padding_vertical_material&quot;
 android:left=&quot;@dimen/abc_button_padding_horizontal_material&quot;
 android:right=&quot;@dimen/abc_button_padding_horizontal_material&quot;
 android:top=&quot;@dimen/abc_button_padding_vertical_material&quot;/&gt;
 &lt;/shape&gt;
 &lt;/item&gt;
 &lt;item android:id=&quot;@android:id/mask&quot;&gt;
 &lt;shape&gt;
 &lt;stroke
 android:width=&quot;2dp&quot;
 android:color=&quot;@color/abc_btn_colored_borderless_text_material&quot;/&gt;
 &lt;solid android:color=&quot;@android:color/white&quot;/&gt;
 &lt;corners android:radius=&quot;@dimen/abc_control_corner_material&quot;/&gt;
 &lt;/shape&gt;
 &lt;/item&gt;
 &lt;/ripple&gt;
&lt;/inset&gt;
</code></pre>
styles.xml

<pre class="lang-xml prettyprint-override"><code>&lt;style name=&quot;Button.Outlined&quot; parent=&quot;Widget.AppCompat.Button.Borderless.Colored&quot;&gt;
 &lt;item name=&quot;android:background&quot;&gt;@drawable/bg_btn_outlined&lt;/item&gt;
&lt;/style&gt;
</code></pre>
At this point, we should have an outlined button that responds to touches, respects the <code>enabled=&quot;false&quot;</code> state and of the same height as the default <code>Widget.AppCompat.Button</code>:
<a href="https://i.stack.imgur.com/96gPy.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/96gPy.jpg" alt="enter image description here" /></a>
Now, from here you can start customizing colors by providing your own implementation of the <code>@color/abc_btn_colored_borderless_text_material</code> color selector.

blocks|key|1083664|text|通过将Material的style属性设置为@style/Widget.MaterialComponents.Button.OutlinedButton，并将app:strokeColor属性值设置为您喜欢的颜色，您可以很容易地做到这一点。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1083665|示例：|1083666|<com.google.android.material.button.MaterialButton

You could do this pretty easily by setting Material Design Button's <code>style</code> attribute to <code>@style/Widget.MaterialComponents.Button.OutlinedButton</code> and setting <code>app:strokeColor</code> attribute value to your preferred color.

example:

<pre><code>&lt;com.google.android.material.button.MaterialButton
 android:text="Rounded outlined button"
 android:layout_height="wrap_content"
 android:layout_width="wrap_content"
 android:id="@+id/btnRound"
 style="@style/Widget.MaterialComponents.Button.OutlinedButton"
 app:strokeColor="@color/colorPrimaryDark"/&gt;
</code></pre>

Put below code in Styles.xml file :

<pre><code>&lt;style name="btn_start_new_discussion"&gt;
 &lt;item name="android:layout_marginTop"&gt;15dp&lt;/item&gt;
 &lt;item name="strokeWidth"&gt;2dp&lt;/item&gt;

 &lt;item name="cornerRadius"&gt;10dp&lt;/item&gt;
&lt;/style&gt;
</code></pre>

blocks|key|1083735|text|你也可以用来完成这个任务。要做到这一点，只需使用OutlinedButton创建一个可组合的函数，并传递您想要的as参数：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1083736|@Composable
fun+OutlineButton()+{
++++OutlinedButton(
++++++++onClick+=+{+//TODO+-+implement+click+here+},
++++++++border+=+BorderStroke(1.dp,+Color.Blue),+//+<--+border+property
++++++++shape+=+RoundedCornerShape(corner+=+CornerSize(20.dp)),
++++++++colors+=+ButtonDefaults.outlinedButtonColors(contentColor+=+Color.Blue)
++++){
++++++++Text(text+=+"CONFIRM")
++++}
}|code-block|syntax|javascript|1083737|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|$]]

You can do this with Jetpack Compose too. To do it, just create a composable function with a OutlinedButton and pass the as parameter the border you want:
<pre><code>@Composable
fun OutlineButton() {
 OutlinedButton(
 onClick = { //TODO - implement click here },
 border = BorderStroke(1.dp, Color.Blue), // &lt;-- border property
 shape = RoundedCornerShape(corner = CornerSize(20.dp)),
 colors = ButtonDefaults.outlinedButtonColors(contentColor = Color.Blue)
 ){
 Text(text = &quot;CONFIRM&quot;)
 }
}
</code></pre>

blocks|key|945369|text|只需使用带有大纲样式的MaterialButton。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|945370|<com.google.android.material.button.MaterialButton

<h3>Just use <code>MaterialButton</code> with an outline style.</h3>
<pre><code>&lt;com.google.android.material.button.MaterialButton
 ...
 style=&quot;@style/Widget.MaterialComponents.Button.OutlinedButton&quot;
 android:text=&quot;Delete Mentor Manager&quot;
 app:strokeColor=&quot;@color/....&quot;
 app:strokeWidth=&quot;1dp&quot; /&gt;
</code></pre>

I know how to make Material Design button with color fill:

<pre><code>style="@style/Widget.AppCompat.Button.Colored"
</code></pre>

And no-bordered transparent button:

<pre><code>style="@style/Widget.AppCompat.Button.Borderless.Colored"
</code></pre>

However, is there a way to make Material design bordered (transparent inside) button? Something like below?
