Android: Strike-through a TextView

There are many scenarios in which we need to show a Strike-through text to an android user like Old prices, old offers, etc. But android doesn’t give any such option via XML file. If you want to show a strike-through text you can do it programming using PaintFlags. You can set paint flags Paint.STRIKE_THRU_TEXT_FLAG to a TextView and it will add a strike-through to the text.

TextView textView = (TextView) findViewById(R.id.text);
textView.setPaintFlags(textView.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);

1 2	TextView textView = (TextView) findViewById(R.id.text); textView.setPaintFlags(textView.getPaintFlags() \| Paint.STRIKE_THRU_TEXT_FLAG);

But when you need it in your XML. As I am using Data Binding so my priority is to set everything related to a view in the xml. So I found this workaround on stackoverflow for my problem.

We just have to set a background that contains a line to our TextView like I did.

<TextView
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:background="@drawable/strike_through"
   android:padding="5dp"
   android:text="@{prod.old_price}"/>

<TextView

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:background="@drawable/strike_through"

android:padding="5dp"

android:text="@{prod.old_price}"/>

and the drawable for the strike-through line

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle">
            <solid android:color="#FFFFFF"/>
        </shape>
    </item>
    <item>
        <shape android:shape="line">
            <stroke android:width="1dp"
                    android:color="#808080"/>
        </shape>
    </item>
</layer-list>

<?xml version="1.0" encoding="utf-8"?>

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

<item>

</shape>

</item>

<item>

<stroke android:width="1dp"

android:color="#808080"/>

</shape>

</item>

</layer-list>

and you will get the text as you want.
