Kotlin TextView and EditText

TextView and EditText are two important widgets in Android app development that are used to display and edit text respectively. In this tutorial, we will discuss how to use these widgets in Kotlin.

Syntax

TextView

<TextView
    android:id="@+id/textView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Hello, World!" />

EditText

<EditText
    android:id="@+id/editText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="Enter Text Here" />

Example

TextView

val textView : TextView = findViewById(R.id.textView)
textView.text = "Hello, World!"

EditText

val editText : EditText = findViewById(R.id.editText)
val text : String = editText.text.toString()

Output

TextView

When you run the app, the TextView will display the text "Hello, World!".

EditText

When the user types text into the EditText and clicks a button to get the text, the app will return the text that was entered.

Explanation

TextView

TextView is a widget used to display text on the screen. In the above example, we have set the text property of TextView to "Hello, World!". We can also set the text programmatically by getting the TextView using its ID and setting its text property.

EditText

EditText is a widget used to edit text on the screen. In the above example, we have set the hint property of EditText to "Enter Text Here". We can also get the text that was entered into EditText by getting the EditText using its ID and getting its text property.

Use

TextView and EditText are two of the most commonly used widgets in Android app development. TextView is used to display text and EditText is used to get user input. We can use these widgets to create dynamic user interfaces in our apps.

Important Points

• TextView is used to display text and EditText is used to edit text.
• We can set the text property of the TextView or the hint property of the EditText in XML or programmatically.
• We can get the text that was entered into EditText by getting its text property.

Summary

In this tutorial, we discussed how to use TextView and EditText in Kotlin. We covered the syntax, examples, output, explanation, use, important points, and summary of using these widgets. With this knowledge, you can now use TextView and EditText to create dynamic user interfaces in your Android apps.
