Customizing Android Studio Theme: A Step-by-Step Guide

Android Studio provides a robust set of tools for customizing the appearance and behavior of our applications. One such aspect is theming, which allows us to define different styles for our app's UI elements. In this article, we will explore how to customize the theme of our Android application programmatically.

To begin with, let's create two themes, Theme1 and Theme2, each consisting of three attributes: text color, background color, and text size. We can use the `?attr` syntax to refer to these custom attributes in our layout files. For example, if we want to set the text color of a TextView to the value specified by `textColor`, we would use `android:textColor='?attr/textColor'`.

Next, we will group our custom attributes together and give them a name. This is done using the `style` element in our styles.xml file. We can then assign values to these style attributes using the `attr` element. For instance, let's define a few color resources:

```

#FF0000

#00FF00

```

Now, let's see how to apply these themes programmatically. We can set the theme by calling `setTheme()` in our Activity's `onCreate()` method before `super.onCreate()` and `setContentView()`. For example:

```java

public class MainActivity extends AppCompatActivity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

// Apply the theme programmatically

setTheme(R.style.Theme1);

}

```

When we group a set of style attributes together and give it a name, it becomes our theme. If we want to use any custom attributes, we need to define those attributes first.

In this article, 'android change theme programmatically,' we will see how to change the theme dynamically. After selecting a theme, when we go back to our activity, we want the theme to be applied. We can provide a new setting that allows users to choose from a list of themes. By following these steps, you can customize your Android application's theme and create a unique look for your app.

Remember to define the values for colors or dimensions and associate them with proper names. Also, take special care when changing the theme programmatically, as it may affect the layout attributes defined in your activity.
