How to add dictionary on word search ?

I want to add button in popup where highlighter underline is howing .
And on click there my text to speech will open and start working .

So I jut want to add feature in that popup and on click there my method will start work?

i have done that but when we play tech it works but show toast "add annotation failed!".

I have done this in OnPDFSelectEnd method
if( rad_group.getCheckedRadioButtonId() == R.id.rad_copy )
{
// Toast.makeText(PDFViewAct.this, "todo copy text:" + sel_text, Toast.LENGTH_SHORT).show();

android.content.ClipboardManager clipboard = (android.content.ClipboardManager) getSystemService(CLIPBOARD_SERVICE);
android.content.ClipData clip = android.content.ClipData.newPlainText("RACHNA SAGAR", sel_text);
clipboard.setPrimaryClip(clip);
}
else if( m_doc.CanSave() )
{
boolean ret = false;
if( rad_group.getCheckedRadioButtonId() == R.id.rad_copy )
{
// Toast.makeText(PDFViewAct.this, "todo copy text:" + sel_text, Toast.LENGTH_SHORT).show();
android.content.ClipboardManager clipboard = (android.content.ClipboardManager) getSystemService(CLIPBOARD_SERVICE);
android.content.ClipData clip = android.content.ClipData.newPlainText("RACHNA SAGAR", sel_text);
clipboard.setPrimaryClip(clip);
}
else if( rad_group.getCheckedRadioButtonId() == R.id.rad_highlight )
ret = m_view.PDFSetSelMarkup(0);
else if( rad_group.getCheckedRadioButtonId() == R.id.rad_underline )
ret = m_view.PDFSetSelMarkup(1);
else if( rad_group.getCheckedRadioButtonId() == R.id.rad_strikeout )
ret = m_view.PDFSetSelMarkup(2);
else if( rad_group.getCheckedRadioButtonId() == R.id.rad_squiggly )
ret = m_view.PDFSetSelMarkup(4);
else if( rad_group.getCheckedRadioButtonId() == R.id.rad_Text_to_Speech )
{
txtText=sel_text;
speakOut();
}

if( !ret )
Toast.makeText(PDFViewAct.this, "add annotation failed!", Toast.LENGTH_SHORT).show();
}
else
Toast.makeText(PDFViewAct.this, "can't write or encrypted!", Toast.LENGTH_SHORT).show();

You see the toast, because ret is not set in case of TTS (text to speech).
To solve this, you can:

1. Initialize ret with true:
   Code:

   boolean ret = true;
2. OR set ret = true; inside:
   Code:

   else if( rad_group.getCheckedRadioButtonId() == R.id.rad_Text_to_Speech ) { ret = true; txtText=sel_text; speakOut(); }
