creating a strikethrough text?

Android Problem Overview

Can I create a strikethrough text in Android, I mean adding a special value in the TextView tag that can make this possible?

<TextView
    android:id="@+id/title" 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 
    android:textColor="#040404"
    android:typeface="sans" 
    android:textSize="12dip"
    android:textStyle="bold"/>

Paint.STRIKE_THRU_TEXT_FLAG

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

> For painting text, there are several bit flags for doing things like > bold, italics, and yes strikethrough. So to enable the strikethrough, > you need to flip the bit that corresponds to this flag. The easiest > way to do this is to use a bitwise-or on the current flags and a > constant that corresponds to a set of flags with only the > strikethrough flag enabled.

Edit from Comment by Ε Г И І И О :

For any one wanting to remove this flag, this is how:

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

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"
 />

You can do this in three ways, by either setting foreground in TextView or setting PaintFlag or declaring a string as <strike>your_string</strike> in strings.xml. For example,

Through PaintFlag

This is the simplest method you just have to set strikethrough flag on your TextView as,

yourTextView.setPaintFlags(Paint.STRIKE_THRU_TEXT_FLAG);

it will strike through your TextView.

Through foreground drawable(Works only for API 23+)

If your minSdkVersion is API version 23 +, then you can strike through your TextView by setting a foreground as,

<?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>

Now, you just have to set above drawable in your TextView as foreground. For example,

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Your Textview with StrikeThrough"
    android:foreground="@drawable/strikethrough_foreground" />  <!-- this is available above --!>

Through strings.xml

In this method, you have to declare your string in strings.xml as strike through as,

<string name="strike_line"> <strike>This line is strike throughed</strike></string>

Note

But I recommend you to strike through your TextView by setting foreground drawable. Because through drawable you can easily set your strike-through line color(as like I set as red color in above example) or size or any other style property. While in the other two methods default text color is strikethrough color.

Solution 4 - Android

If you are using Kotlin:

your_text_view.apply {
    paintFlags = paintFlags or Paint.STRIKE_THRU_TEXT_FLAG
    text = "Striked thru text"
}

Solution 5 - Android

try this :

richTextView = (TextView)findViewById(R.id.rich_text);  
  
    // this is the text we'll be operating on  
    SpannableString text = new SpannableString("Lorem ipsum dolor sit amet");  

    text.setSpan(new ForegroundColorSpan(Color.RED), 0, 5, 0);  
  
    // make "ipsum" (characters 6 to 11) one and a half time bigger than the textbox  
    text.setSpan(new RelativeSizeSpan(1.5f), 6, 11, 0);  
  
    // make "dolor" (characters 12 to 17) display a toast message when touched  
    final Context context = this;  
    ClickableSpan clickableSpan = new ClickableSpan() {  
        @Override  
        public void onClick(View view) {  
            Toast.makeText(context, "dolor", Toast.LENGTH_LONG).show();  
        }  
    };  
    text.setSpan(clickableSpan, 12, 17, 0);  
  
    // make "sit" (characters 18 to 21) struck through  
    text.setSpan(new StrikethroughSpan(), 18, 21, 0);  
  
    // make "amet" (characters 22 to 26) twice as big, green and a link to this site.  
    // it's important to set the color after the URLSpan or the standard  
    // link color will override it.  
    text.setSpan(new RelativeSizeSpan(2f), 22, 26, 0);  
    text.setSpan(new URLSpan("http://www.djsad.com"), 22, 26, 0);  
    text.setSpan(new ForegroundColorSpan(Color.GREEN), 22, 26, 0);  
  
    // make our ClickableSpans and URLSpans work  
    richTextView.setMovementMethod(LinkMovementMethod.getInstance());  
  
    // shove our styled text into the TextView          
    richTextView.setText(text, BufferType.SPANNABLE);

I am just copying my answer. Hope it will help for someone If you have a single word we can use drawable. Following is the example: http://schemas.android.com/apk/res/android">

<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)

Solution 7 - Android

In Kotlin you can create extension property:

inline var TextView.strike: Boolean
    set(visible) {
        paintFlags = if (visible) paintFlags or Paint.STRIKE_THRU_TEXT_FLAG
        else paintFlags and Paint.STRIKE_THRU_TEXT_FLAG.inv()
    }
    get() = paintFlags and Paint.STRIKE_THRU_TEXT_FLAG == Paint.STRIKE_THRU_TEXT_FLAG

And use:

textView.strike = true

Solution 8 - Android

This fits nicely into databinding:

@BindingAdapter("strikethrough")
@JvmStatic
fun strikethrough(view: TextView, show: Boolean) {
    view.paintFlags = if (show) {
        view.paintFlags or STRIKE_THRU_TEXT_FLAG
    } else {
        view.paintFlags and Paint.STRIKE_THRU_TEXT_FLAG.inv()
    }
}

Then in your xml:

    <TextView
        android:id="@+id/line_item_name"
        android:textAppearance="?attr/textAppearanceBody2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Club sandwich with ranch dressing"
        app:strikethrough="@{viewModel.isItemChecked}"/>

Solution 9 - Android

Just use this and you are done . For Activity :

TextView t= (TextView).findViewById(R.id.thousand));
t.setPaintFlags(t.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);

For Xml :

<RelativeLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content">

            <TextView
                android:id="@+id/text_view_original_cash_amount"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:padding="5dp"
                android:textColor="@android:color/darker_gray"
                android:text="Rs. 1,999"/>

            <View
                android:layout_width="wrap_content"
                android:layout_height="1dp"
                android:background="@android:color/darker_gray"
                android:layout_centerVertical="true"
                android:layout_alignStart="@id/text_view_original_cash_amount"
                android:layout_alignEnd="@id/text_view_original_cash_amount"
                android:layout_alignLeft="@id/text_view_original_cash_amount"
                android:layout_alignRight="@id/text_view_original_cash_amount" /> 
</RelativeLayout>

Solution 10 - Android

In kotlin:

to do:

textView.paintFlags= textView.paintFlags or Paint.STRIKE_THRU_TEXT_FLAG

to undo:

textView.paintFlags= textView.paintFlags and Paint.STRIKE_THRU_TEXT_FLAG.inv()

Solution 11 - Android

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

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

cheers

Solution 12 - Android

As suggested by alejandro-h-cruz, this is the Kotlin extension function to help doing so.

    private fun TextView.strikeThrough(shouldStrike: Boolean) {
        paintFlags = if (shouldStrike) {
            paintFlags or Paint.STRIKE_THRU_TEXT_FLAG
        } else {
            paintFlags and Paint.STRIKE_THRU_TEXT_FLAG.inv()
        }
    }

Solution 13 - Android

In your observable view model

fun getStrikeContent(): String {
    return "Hello"
}


 companion object {
    @BindingAdapter("strike")
    @JvmStatic
    fun loadOldPrice(view: TextView, value: String) {
        view.text = value
        view.paintFlags = STRIKE_THRU_TEXT_FLAG
    }
}

then in your xml

     <TextView
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         app:strike="@{itemViewModel.strikeContent}" />
