How to change the default style of buttons in Android development (change button and font color)

Create a button in xml like this

Although it is not ugly, we still hope to be able to control the button style ourselves in different situations.

Select res--values--themes--themes.xml, the parent is like this

Modify it to

<style name="Theme.GoodWeatherNew" parent="Theme.MaterialComponents.DayNight.Bridge">

You can change the style yourself

How to change it

Create an xml file under drawable

Select element as shape

Add code to xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    //背景颜色
    <solid android:color="#5B9798" />
    //设置边框线的粗细和颜色
    <stroke
        android:width="0dp"
        android:color="@color/transparent" />

    <padding
        android:bottom="2dp"
        android:left="2dp"
        android:right="2dp"
        android:top="2dp" />
    //角参数可以单独设置
    <corners android:radius="10dp" />

</shape>

Make the following reference in your activity

android:background="@drawable/button"
