Android TextView – Text Shadow

TextView – Set Text Shadow

To set a blurred shadow of text underneath the text in TextView widget, you can use shadowColor, shadowDx, shadowDy and shadowRadius attributes of TextView.

• shadowColor specifies the color of shadow. You can specify color in rgb, argb, rrggbb, or aarrggbb formats.
• shadowDx specifies the horizontal offset of the shadow. It takes a float value.
• shadowDy specifies the vertical offset of the shadow. It takes a float value.
• shadowRadius specifies the blur radius of the shadow. It takes a float value.

<TextView
	android:shadowColor="#FF5722"
	android:shadowDx="8"
	android:shadowDy="8"
	android:shadowRadius="4"
	android:text="Welcome to Kotlin Android Tutorial." />

Example

Create an Android Application with Kotlin support and Empty Activity. Create two TextView widgets with different shadow attributes.

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

    tools:context=".MainActivity">

    <TextView
        android:id="@+id/text_view_1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textAlignment="center"

        android:shadowDx="5"
        android:shadowDy="5"
        android:shadowRadius="2"
        android:text="Welcome to Kotlin Android Tutorial." />
