Is there an easy way to strike through text in an app widget?

Question

I was wondering if there is an easy way to strike text within an app widget in Android. In a normal activity, it is pretty easy, using textview flags:

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

But since in an app widget, I can use only remoteviews... I do not know if this is possible

Anyone know something about this?

Thanks!

To do it programatically in a textview, untested in other views >>

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

This is not possible for App-Widgets. They only work with RemoteViews and there is no method to read the paint flags. – Ridcully Mar 17 '14 at 17:53

Another way to do it programmatically which looks a bit less like a hack than the Paint way:

Instead of doing:

tv.setText(s);

do:

private static final StrikethroughSpan STRIKE_THROUGH_SPAN = new StrikethroughSpan();
...
tv.setText(s, TextView.BufferType.SPANNABLE);
Spannable spannable = (Spannable) tv.getText();
spannable.setSpan(STRIKE_THROUGH_SPAN, 0, s.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

This does not answer the question as this does not apply to `RemoteView` – Alex.F Jan 22 '15 at 13:12
@Alex.F I am a bit surprised since this does work for instance in Notifications (which are remote views). I must admit I haven't tested with AppWidgets though. – BoD Jan 22 '15 at 17:19

It does work with App Widgets (any framework span that implements ParcelableSpan should work) – Karsten Apr 17 '15 at 01:18

You can use this:

remoteviews.setInt(R.id.YourTextView, "setPaintFlags", Paint.STRIKE_THRU_TEXT_FLAG | Paint.ANTI_ALIAS_FLAG);

Of course you can also add other flags from the android.graphics.Paint class.

First it is unclear what is remoteviews , plus doesn't work for all android versions. – akshat tailang Nov 28 '18 at 18:26
This is the answer we are looking for, working with app-widgets on androidTextViews are only accessible through removeViews. Accessing TextView directly is not possible at this point. – endevour Mar 19 '20 at 14:52

2015 Update: Folks, this is for very old versions of Android. See other answers for modern solutions!

To strike through the entire text view, you can use a specific background image to simulate the strikethrough effect:

android:background="@drawable/bg_strikethrough"

Where the bg_strikethrough drawable is a 9-patch that keeps a solid line through the middle, growing either side, with however much padding you think is reasonable. I've used one like this:

(enlarged for clarity.. 1300% !)

That is my HDPI version, so save it (the first one https://i.stack.imgur.com/nt6BK.png) as res/drawable-hdpi/bg_strikethrough.9.png and the configuration will work as so:

For doing this you can use this

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

and for remove you can use this

 title.setPaintFlags(title.getPaintFlags() & (~Paint.STRIKE_THRU_TEXT_FLAG));

how can i add strike color – Harsha Feb 28 '18 at 14:54
@Harsha this seems to only allow you to use the color of the text. If you want a different strikethrough color you'll have to try other implementation method. – Michael Apr 02 '19 at 17:08

Here is an extension for all you Kotlin folks

fun TextView.showStrikeThrough(show: Boolean) {
    paintFlags =
            if (show) paintFlags or Paint.STRIKE_THRU_TEXT_FLAG
            else paintFlags and Paint.STRIKE_THRU_TEXT_FLAG.inv()
}

Usage

textView.showStrikeThrough(true)

Limitation

Strikethroughs can only be the same color as the text

(i.e. Red text and blue strikethrough is not possible)

It is really easy if you are using strings:

<string name="line"> Not crossed <strike> crossed </strike> </string>

And then just:

<TextView 
        ...
         android:text="@string/line"
 />

For multiline TextView you should use android.text.style.CharacterStyle like this:

SpannableString spannable = new SpannableString(text);
spannable.setSpan(new StrikethroughSpan(), 0, text.length(), Spanned.SPAN_INCLUSIVE_EXCLUSIVE);
remoteViews.setTextViewText(R.id.itemText, spannable);

Make a drawable file, striking_text.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="false">
        <shape android:shape="line">
            <stroke android:width="1dp" android:color="@android:color/holo_red_dark" />
        </shape>
    </item>
</selector>

layout xml

 <TextView
            ....
            ....
            android:background="@drawable/striking_text"
            android:foreground="@drawable/striking_text"
            android:text="69$"
           />

If your min SDK below API level 23 just use the background or just put the background and foreground in the Textview then the android studio will show an error that says create a layout file for API >23 after that remove the android:foreground="@drawable/stricking_text" from the main layout

Output look like this:

Add the line below:-

TextView tv=(TextView) v.findViewById(android.R.id.text1);
tv.setPaintFlags(tv.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);

use your reference instead of "tv"

Android resources have pretty good HTML markup support
The below HTML elements are supported:

Bold: <b>, <em>
Italic: <i>, <cite>, <dfn>
25% larger text: <big>
20% smaller text: <small>
Setting font properties: <font face=”font_family“ color=”hex_color”>. Examples of possible font families include monospace, serif, and sans_serif.
Setting a monospace font family: <tt>
Strikethrough: <s>, <strike>, <del>
Underline: <u>
Superscript: <sup>
Subscript: <sub>
Bullet points: <ul>, <li>
Line breaks: <br>
Division: <div>
CSS style: <span style=”color|background_color|text-decoration”>
Paragraphs: <p dir=”rtl | ltr” style=”…”>

Note however that it's not rendered in android studio layouts preview. Last tested on Android Studio 3.3.1

For example, the Strikethrough will look like that:

<string name="cost"><strike>$10</strike> $5 a month</string>

You Can use data binding! In XML layout just do app:strike="@{true}"

@BindingAdapter("strike")
fun bindTextView(view: TextView, strike: Boolean) {
    if (strike) {
        view.paintFlags = view.paintFlags or Paint.STRIKE_THRU_TEXT_FLAG or Paint.ANTI_ALIAS_FLAG
    } else {
        view.paintFlags = 0 or Paint.ANTI_ALIAS_FLAG
    }
}

You should not set flag but add it to existing, because there can be other flags set (for antialiasing, for example) – artem May 21 '23 at 11:22

and then add .setPaintFlags in variableTv :

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

I've done this on a regular (local) TextView, and it should work on the remote variety since the docs list the method as equivalent between the two:

I know, I am answering an old question, it might be helpful for someone else, for striking out a particular portion of TextView programmatically.

TextView textView = (TextView) findViewById(R.id.textView);
textView.setText("Text need to be set here", TextView.BufferType.SPANNABLE);
Spannable spannable = (Spannable) textView.getText();
spannable.setSpan(new StrikethroughSpan(), 5, 8, Spanned.SPAN_INCLUSIVE_EXCLUSIVE);

So, in this example code, 5 is starting position and 8 is ending position of text need to be stricken out, so after running this code we can get the text "need" with striked out. Hope it will helpful for someone else.

Is there an easy way to strike through text in an app widget?
