What is View components in Android SDK?

In the Android SDK, View components are the basic building blocks for user interface design. Each View is a rectangle that can display text, images, or XML files. Views also handle user interactions like touch events, making them essential for creating responsive applications. Common View components include TextView, Button, ImageView, EditText, and more.

Developers can create custom Views by extending the View class or using existing Views to build complex layouts with ViewGroups like LinearLayout, RelativeLayout, and ConstraintLayout.

Here is a simple example of how to use some common View components in an Android XML layout file:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Hello, World!" /> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Click Me" /> <EditText android:layout_width="match_parent" android:layout_height="wrap_content" android:hint="Enter text here" /> </LinearLayout>
