Button text automatically change to capital letter in android

I assume, You using 23 API Level .Its default there.
Don't worry.

Just add

android:textAllCaps="false"

How do I include lowercase characters in the text on a button using Android API 10?

Step #1: Open app/src/main/res/values/styles.xml. This should show a stub custom theme, inheriting from a Theme.AppCompat-based theme, given your symptoms.

Step #2: Add a new <style> to that file:

<style name="MixedCaseButton" parent="Widget.AppCompat.Button">
  <item name="textAllCaps">false</item>
</style>

You will notice that this references textAllCaps. The native implementation of textAllCaps is new to API Level 14. This theme is using the backport of textAllCaps supplied by appcompat-v7, which you are using, given your symptoms.

Step #3: Add this element to your custom theme, the one that already existed in the styles.xml file:

<item name="buttonStyle">@style/MixedCaseButton</item>

This will give you an overall styles.xml file resembling:

<resources>

  <!-- Base application theme. -->
  <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="buttonStyle">@style/MixedCaseButton</item>
  </style>

  <style name="MixedCaseButton" parent="Widget.AppCompat.Button">
    <item name="textAllCaps">false</item>
  </style>

</resources>

(though the other contents of the pre-existing style resource may vary somewhat)

Step #4: Run your app, and you will see the button appear in mixed case. Please note that this violates the Material Design aesthetic.

Button text always showing in uppercase

I'm guessing you see this on Android as it is the default for button text and has been since Lollipop.

<item name="android:textAllCaps">false</item>

Center Text inside Button and reduce button padding

Apart from

android:minWidth="0dp"
android:minHeight="0dp"

you need to set includeFontPadding to false and padding to 0dp so you can create new style and use it as

 <style name="NoPaddingTextButton" parent="Widget.MaterialComponents.Button.TextButton">
        <item name="android:padding">0dp</item>
        <item name="android:includeFontPadding">false</item>
 </style> 

and use it

 <Button
        android:id="@+id/btn_add"
        style="@style/NoPaddingTextButton"
        ...
 />

Note: You might still see extra padding at top and bottom but that is for characters like p or ' etc, you can verify it with

    android:text="ADD p '`"

When android:textAllCaps="true" is set (it is by default on Buttons), the system will essentially call yourText.toUpperCase(Locale.getDefault()) on whatever text you set to the view. To work around this, set textAllCaps to false, and then uppercase it using yourString.toUpperCase(Locale.US).
