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

Posted by: admin March 11, 2020 Leave a comment

Questions:

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!

How to&Answers:

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.

Answer:

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);

Answer:

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);

Answer:

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:

alt text

(enlarged for clarity.. 1300% !)

alt text

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

alt text

Answer:

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));

Answer:

If you have a single word we can use drawable.
Following is the example:

<item android:state_pressed="false"><shape android:shape="line">
        <stroke android:width="2dp" android:color="#ffffff" />
    </shape>
</item>

if you have multiple lines you can use the following code:

TextView someTextView = (TextView) findViewById(R.id.some_text_view);
someTextView.setText(someString);
someTextView.setPaintFlags(someTextView.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG)

Answer:

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);

Answer:

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"
 />

Answer:

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”

Answer:

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)

Answer:

try this code

textview.setText((Html.fromHtml("<strike>hello world!</strike>")));

Answer:

create a drawable

<?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="@color/onePlusRed" />
        </shape>
    </item>
</selector>

and use it as foreground.
android:foreground="@drawable/strike_through"

Answer:

I tried few options but, this works best for me:

String text = "<strike><font color=\'#757575\'>Some text</font></strike>";
textview.setText(Html.fromHtml(text));

cheers

Answer:

you add in :

TextView variableTv = (TextView) findViewById(R.id.yourText);

you set/add in You variable :

variableTv.setText("It's Text use Style Strike");

and then add .setPaintFlags in variableTv :

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

Answer:

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.

Answer:

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>

Answer:

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:

remote_text_view.setText(Html.fromHtml("This is <del>crossed off</del>."));
