how to use com google android material objects and change button background with examples

Material design is the design language of the Android operating system. It is a design system developed and maintained by Google. Material Design aims to provide a consistent user experience across all devices and platforms. The design guidelines of Material Design includes guidelines for typography, color scheme, layout, and UI interactions. The Material Design system provides a wide range of pre-built components that can be used in Android applications. These components are known as Material Objects.

Material Objects are reusable components that are provided as a part of the Material Design system. They include buttons, text fields, progress bars, and many other UI components. By using Material Objects, you can save a lot of time and effort in designing user interfaces. You can also ensure that your application looks consistent with other Android apps.

In this article, we will learn how to use Material Objects in Android applications and how to change the background color of a button.

Prerequisites:

Before you proceed with this tutorial, you should have a basic understanding of Android Application development using Android Studio. You should also have a basic knowledge of XML and Java programming languages.

Step 1: Add the Material Design Library to your Android project

To use Material Objects in your Android application, you need to add the Material Design Library to your project. To add the library, follow these steps:

Open your Android Studio project.

In the project explorer, right-click on your app folder and select "Open Module Settings".

Select the "Dependencies" tab.

Click the "+" button at the bottom of the screen.

Select "Library dependency".

In the search bar, type "com.google.android.material:material".

Select the latest version of the Material Design library and click "OK".

Step 2: Add a button to your Android application

To add a button to your Android application, follow these steps:

Open your activity_main.xml layout file in Android Studio.

Add the following code to your layout file:

<com.google.android.material.button.MaterialButton
    android:id="@+id/myButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="My Button" />

In the above code, we have added a MaterialButton to our layout with the ID "myButton" and a text value of "My Button".

Step 3: Change the background color of the button

To change the background color of the button, use the setBackgroundColor() method of the MaterialButton class. Follow these steps:

Open your MainActivity.java file.

Add the following code to the onCreate() method:

MaterialButton myButton = findViewById(R.id.myButton);
myButton.setBackgroundColor(getResources().getColor(R.color.colorPrimary));

In the above code, we have obtained the reference to the MaterialButton with the ID "myButton" and changed its background color to the "colorPrimary" color defined in the colors.xml file.

Step 4: Run your Android application

Now that you have added a MaterialButton and changed its background color, you can run your Android application. Follow these steps to run your application:

Connect your Android device to your computer using a USB cable.

Make sure that the "USB Debugging" option is enabled on your device.

In Android Studio, click the "Run" button in the toolbar.

Select your device from the list of devices and click "OK".

Your application will be deployed to your device and will start running.

Conclusion:

In this tutorial, we have learned how to use Material Objects in Android applications and how to change the background color of a button using the Material Design library. By using Material Objects, you can make your Android application look consistent with other Android apps and save a lot of time and effort in designing user interfaces. The Material Design system provides a wide range of pre-built components that can be used in Android applications.

Sure! Let's dive deeper into Material Design and the usage of Material Objects.

Material Design:

Material Design is a design language developed by Google that was launched in 2014. It aims to create a visual language for creating a seamless and delightful experience across all devices and platforms. It provides a set of guidelines for designers and developers to create UI interfaces that are consistent, usable, and user-friendly.

Material Design is based on three principles: Material, Motion, and Depth. Material refers to the use of paper and ink or tactile elements that mimic the real-world behavior of the physical world. Motion refers to the use of motion to enable users to smoothly navigate between different screens and views. Depth refers to the use of shadow and light to create a sense of hierarchy and focus.

Material Objects:

Material Objects are a collection of UI components that are provided by the Material Design library. These components include buttons, progress bars, text fields, sliders, spinners, cards, and many more. These components are pre-designed and easy to use.

Material Objects make it easy to implement Material Design guidelines in your Android application. By using these pre-built components, you can save time and effort in designing user interfaces that are consistent with other Android applications.

In addition to the pre-built components, the Material Design library provides a set of APIs for customizing and building new components. These APIs allow developers to customize the color, shape, size, and behavior of the Material Objects to suit their needs.

How to use Material Objects:

To use Material Objects in your Android application, you need to add the Material Design library to your project. You can do this by adding the following line to your build.gradle file:

implementation 'com.google.android.material:material:1.4.0'

After adding the library, you can use the Material Objects in your layout XML files by using the respective view tag. For example, to add a MaterialButton component, you can use the following code:

<com.google.android.material.button.MaterialButton
    android:id="@+id/myButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="My Button" />

In addition to using the pre-built components, you can customize the appearance and behavior of the Material Objects by using the API provided by the Material Design library. For example, to change the background color of a MaterialButton, you can use the setBackgroundColor() method:

MaterialButton myButton = findViewById(R.id.myButton);
myButton.setBackgroundColor(getResources().getColor(R.color.colorPrimary));

Conclusion:

Material Design provides a set of guidelines and UI components to help developers create user interfaces that are consistent, usable, and user-friendly. Material Objects are a collection of pre-built components that make it easy for developers to implement Material Design guidelines in their Android applications. By using Material Objects, developers can save time and effort in designing user interfaces that are consistent with other Android applications. The Material Design library provides a set of APIs for customizing and building new components, allowing developers to tailor their interfaces to meet their specific needs.
