Android - add diagonal strike through text

To add a diagonal strike-through effect to text in Android, you can use the StrikeThroughSpan class along with SpannableString or SpannableStringBuilder. Here's how you can achieve it programmatically:

import android.text.SpannableString; import android.text.SpannableStringBuilder; import android.text.style.StrikethroughSpan; import android.widget.TextView; // For a single TextView TextView textView = findViewById(R.id.textView); String text = "Your text here"; SpannableString spannableString = new SpannableString(text); spannableString.setSpan(new StrikethroughSpan(), 0, text.length(), 0); textView.setText(spannableString); // For appending to a SpannableStringBuilder SpannableStringBuilder builder = new SpannableStringBuilder(); builder.append("First line\n"); builder.append("Second line with strikethrough", new StrikethroughSpan(), SpannableStringBuilder.SPAN_EXCLUSIVE_EXCLUSIVE); textView.setText(builder);

If you're dealing with a TextView in XML layout, you can use HTML formatting to achieve the strikethrough effect:

<TextView android:id="@+id/textView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="&lt;strike&gt;Your text here&lt;/strike&gt;" android:layout_margin="16dp" android:textSize="18sp"/>

In the XML above, &lt;strike&gt; and &lt;/strike&gt; are HTML entities for <strike> and </strike>, respectively, which apply the strikethrough effect to the enclosed text.
