Sorry I'm late on this one.
Here is little work around for this
MainActivity
public class MainActivity extends AppCompatActivity {
TextView htmlTextView;
CustomEllipsizeTextView customEllipsizeTextView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
htmlTextView = findViewById(R.id.htmlTextView1);
customEllipsizeTextView = findViewById(R.id.customEllipsizeTextView);
String value = "Hello this is a dummy textview";
String myText = "You can visit my Profile in <a href=\"https://stackoverflow.com/users/7666442/nilesh-rathod?tab=profile\">stackoverflow</a> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis bibendum mattis risus eget pulvinar. Praesenttingd" +

"commodo erat enim, id54654 congue sem tristique vitae. Proin vitae accumsan commodo erat enim, id congue sem tristique vitae. Proin vitae accumsan Pellentesque massa mi, imperdiet eget accums ";
SpannableString spanText2 = new SpannableString(myText);
htmlTextView.setText(value);
if (Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) {
customEllipsizeTextView.setText(Html.fromHtml(spanText2.toString(), Html.FROM_HTML_MODE_LEGACY));
} else {
customEllipsizeTextView.setText(Html.fromHtml(spanText2.toString()));
}
htmlTextView.setMovementMethod(LinkMovementMethod.getInstance());
customEllipsizeTextView.setMovementMethod(LinkMovementMethod.getInstance());
customEllipsizeTextView.setOnTouchListener(new TouchTextView(spanText2));
}
}

OUTPUT
Here is the explanation :
I have debugged TextView and found out the following :
So when you use LinkMovementMethod() actually text is acting as Spannable. In other case it is String.
There is one following condition inside TextView
if (mText instanceof Spannable) {
//executes incase of LinkMovementMethod
result = new DynamicLayout(mText, mTransformed, mTextPaint, wantWidth,
alignment, mTextDir, mSpacingMult, mSpacingAdd, mIncludePad,
mBreakStrategy, mHyphenationFrequency, mJustificationMode,
getKeyListener() == null ? effectiveEllipsize : null, ellipsisWidth);
} else {
//executes without any movementmethod
..create StaticLayout
}
So DynamicLayout internally calls StaticLayout to render text, but it is not setting mMaximumVisibleLineCountinside StaticLayout when coming from DynamicLayout so it is default Integer.MAX_VALUE. But when creating StaticLayout from String, it is actually setting mMaximumVisibleLineCount as maxLines. This mMaximumVisibleLineCount is used for displaying ellipsize. That's why "..." is not displaying.
For displaying the number of lines, the following code works
if (mMaxMode == LINES && mLayout.getLineCount() > mMaximum) {
unpaddedHeight = Math.min(unpaddedHeight, mLayout.getLineTop(mMaximum));
}
mMaximum will be set to maxLines in both case, but mLayout.getLineCount() will be maxLines for one without MovementMethod and for with MovementMethod it will be number of lines of original string
