6 Amazing Ways - Android TextView Strikethrough XML & Kotlin/Java examples

Screenshot - Android TextView Strikethrough XML & Kotlin/java Example -

1. Using strike element.

   strings.xml

<string name="strike_text">1. <strike>StrikeThrough</strike> Using strike</string>

<TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/strike_text"
/>    

2. Using STRIKE_THRU_TEXT_FLAG

   Kotlin

   textview2.paintFlags = textview2.paintFlags or Paint.STRIKE_THRU_TEXT_FLAG
   textview2.text = "2. StrikeThrough Using Paint Flags
   

   Java

   textview2.setPaintFlags(textview2.getPaintFlags()| Paint.STRIKE_THRU_TEXT_FLAG); textview2.setText("2. StrikeThrough Using Paint Flags");

3. Using SpannableString

Kotlin

val content1 = "3.1 StrikeThrough Using SpannableString" val spannableString1 = SpannableString(content1) spannableString1.setSpan(StrikethroughSpan(),0,content1.length,0) textview31.text = spannableString1

Java

textview2.setPaintFlags(textview2.getPaintFlags()| Paint.STRIKE_THRU_TEXT_FLAG);
    textview2.setText("2. StrikeThrough Using Paint Flags");    `

Answer 2

In kotlin it can be done as:

your_textView.paintFlags = Paint.STRIKE_THRU_TEXT_FLAG

Answer 3

To do it in only xml file, this is what I do:

<RelativeLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">

    <TextView
        android:id="@+id/text_view_original_cash_amount"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="5dp"
        android:textColor="@android:color/darker_gray"
        android:text="$36000"/>

    <View
        android:layout_width="wrap_content"
        android:layout_height="1dp"
        android:background="@android:color/darker_gray"
        android:layout_centerVertical="true"
        android:layout_alignStart="@id/text_view_original_cash_amount"
        android:layout_alignEnd="@id/text_view_original_cash_amount"/>

</RelativeLayout>

Hope this helps!

Answer 4

textview.setPaintFlags(textview.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);

you can use the above code in activity to have strike over the text.

And to set through xml refer this

Answer 5

If you define a BindingAdapter

@BindingAdapter("strikeThrough")
public static void strikeThrough(TextView textView, Boolean strikeThrough) {
    if (strikeThrough) {
        textView.setPaintFlags(textView.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);
    } else {
        textView.setPaintFlags(textView.getPaintFlags() & ~Paint.STRIKE_THRU_TEXT_FLAG);
    }
}

it's just

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    ...
    app:strikeThrough="@{true}"
    .../>

in XML layout file.

Answer 6

To strike through, you can use a background image to create the strikethrough effect:

 android:background="@drawable/strike_through"

Where strike_through drawable is a 9-patch image that keeps a line through the middle. This is the easiest way to implement it.

or you can do it programatically as this.

TextView t = (TextView) findViewById(R.id.text);
t.setText("Text here");
t.setPaintFlags(t.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);
