User Interface Design (UI Design)

 User Interface Design (UI Design)

The user interface is a crucial aspect of any Android application, as it is the first point of contact between the user and the app. The Android SDK provides various UI components such as TextView, EditText, Button, ImageView, etc. to design an attractive UI.

Here's an example of how to create a simple layout with a TextView and a Button using XML code:

php

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

   android:layout_width="match_parent"

   android:layout_height="match_parent"

   android:orientation="vertical" >

   

   <TextView

       android:id="@+id/textView"

       android:layout_width="wrap_content"

       android:layout_height="wrap_content"

       android:text="Hello World!" />

   

   <Button

       android:id="@+id/button"

       android:layout_width="wrap_content"

       android:layout_height="wrap_content"

       android:layout_below="@+id/textView"

       android:text="Click Me!" />

   

</RelativeLayout>
