When copying String from any browser page, pasteData works properly. However when copying SpannedString from a message sent item editor(field), the application crashes and shows this error message:

java.lang.ClassCastException: android.text.SpannableString cannot be cast to java.lang.String

My code:

// since the clipboard contains plain text.
ClipData.Item item = clipBoard.getPrimaryClip().getItemAt(0);

// Gets the clipboard as text.
String pasteData = new String();
pasteData = (String) item.getText();

where the ClipboardManager instance defined as clipBoard, below:

clipBoard = (ClipboardManager) context.getSystemService(context.CLIPBOARD_SERVICE);
clipBoard.addPrimaryClipChangedListener(new ClipboardListener());

All I'm trying to do is use pasteData in String format. How to get rid of this error? Any help is appreciated.

From CharSequence.toString()

Returns a string with the same characters in the same order as in this sequence.

You need to use next code. 

String pasteData = item.getText().toString();

You can not cast to android.text.SpannableString because item.getText() returns CharSequence, there are a lot of implementations of it

SpannableString is not String directly. so, you can not cast. but, it can be converted to string. you can convert something to string with concatenating with empty string. 

pasteData = "" + item.getText();

  • Code-only answer is discouraged since it might confuse OP and future readers. Instead, explain what the code does. – Andrew T. Dec 15 '14 at 07:52

    This is a work around, and does not address the root problem. The problem is that item.getText() returns a CharSequence, not a String. OP should use item.getText().toString() to convert the CharSequence to String – Aaron Dougherty Jan 31 '15 at 22:15

If your Spanned text only containing HTML content then you can convert it using Html.toHtml()

String htmlString = Html.toHtml(spannedText);

It has worked for me String htmlString = String.valueOf(Html.fromHtml(contenttext,Html.FROM_HTML_MODE_COMPACT));

This is what it worked for me in Kotlin:

val str = text.toString()

You want to add attribute in Textview in xml file like this

add this -> android:bufferType="spannable"

example:

    <TextView
        android:id="@+id/self_assessment_intro2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:bufferType="spannable"
        android:text="@string/self_assessment_intro2"
        android:textSize="@dimen/self_assessment_intro_text_size" />
