In Android, a TextView is a user interface element that displays text on the screen. There are two types of TextViews: editable and non-editable. The main difference between them is that an editable TextView allows users to input text, while a non-editable TextView only displays text.
An editable TextView is created using the android:editable attribute in the XML layout file. For example, the following code creates an editable TextView with the text "Enter your name:"
<EditText
android:id="@+id/name_textview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Enter your name:" />
The user can input text into this TextView using the keyboard. The text can also be programmatically set or retrieved using the setText() and getText() methods.
On the other hand, a non-editable TextView is created using the android:editable attribute set to "false" in the XML layout file. For example, the following code creates a non-editable TextView with the text "Welcome to my app:"
<TextView
android:id="@+id/welcome_textview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:editable="false"
android:text="Welcome to my app:" />
The user cannot input text into this TextView, but the text can still be programmatically set or retrieved using the setText() and getText() methods.
In summary, editable TextViews are used for user input, while non-editable TextViews are used for displaying text. Both types of TextViews can be set and retrieved programmatically, but only editable TextViews allow users to input text.
