Cannot lower case button text in android studio

Question

You could add android:textAllCaps="false" to the button.

The button text might be transformed to uppercase by your app's theme that applies to all buttons. Check themes / styles files for setting the attribute android:textAllCaps.

<style name="AppTheme" parent="AppBaseTheme">
    <item name="android:buttonStyle">@style/Button</item>
</style>

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

This is fixable in the application code by setting the button's TransformationMethod null, e.g.

mButton.setTransformationMethod(null);

add android:textAllCaps="false" in xml button It's true with this issue.

there are 3 ways to do it.

1.Add the following line on style.xml to change entire application

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

2.Use

android:textAllCaps="false"

in your layout-v21

mButton.setTransformationMethod(null);

3. add this line under the element(button or edit text) in xml

android:textAllCaps="false"

regards

You could set like this

button.setAllCaps(false);

programmatically
