draw line through text in textview

In Kotlin

tv.text = "This is text"
tv.paintFlags = tv.paintFlags or Paint.STRIKE_THRU_TEXT_FLAG

This can help you.

    TextView tv = (TextView) findViewById(R.id.mytext);
    tv.setText("This is strike-thru");
    tv.setPaintFlags(tv.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);

You can use it in your code,however necessary.
