Android – use getprimaryclip() to copy the given data, given {text / plain {null}}

I get the information of {text / plain {null}} when using clipdata, but if I use the deprecated method mclipboard. Gettext(), it will work normally

if (mClipboard.getPrimaryClipDescription().hasMimeType(ClipDescription.MIMETYPE_TEXT_PLAIN)) {
    ClipData clipData = mClipboard.getPrimaryClip();
    ClipData.Item item = clipData.getItemAt(0);
    Log.d(TAG, clipData.toString());
    Log.d(TAG, mClipboard.getText());
}

Update information

There is a problem in Samsung Galaxy label 3

resolvent:

The cause of your problem is unknown. Because it can run on the device I tested (S6 5.0). You may need to check the implementation of the deprecated gettext() method:

public CharSequence getText() {
    ClipData clip = getPrimaryClip();
    if (clip != null && clip.getItemCount() > 0) {
        return clip.getItemAt(0).coerceToText(mContext);
    }
    return null;
}

To get text, it uses the coercetotext() method. According to the description of this method:

     * Turn this item into text, regardless of the type of data it
     * actually contains.

Therefore, I don't think the use of gettext () method is due to performance problems or other reasons

In any case, since the method gettext() uses the deprecated API, as a solution, if calling the suggested API returns null, you can use the source of some parts of this method (specifically, the method coercetotext()):

ClipboardManager mclipboard =(ClipboardManager) getSystemService(CLIPBOARD_SERVICE);
boolean isTextPlain = mclipboard.getPrimaryClip().getDescription().hasMimeType(ClipDescription.MIMETYPE_TEXT_PLAIN);
    CharSequence text = null;
if (isTextPlain){
    ClipData clipData = mclipboard.getPrimaryClip();
    ClipData.Item item = clipData.getItemAt(0);
    if (  item!= null ){
        text = item.getText();
        if (text == null){
            // taken from source of clipData.getText() method
            text =  item.coerceToText(this);
        }
    }
}
