Custom URLSpan don't trigger onClick event, using kotlin [duplicate]

Ok. These are my problems.
I need to user regular expressions to filet out everything except for letters and then I need to encase the found words within a $word tag.
With this str = str.replaceAll(pattern, "$0");.
right now I am filtering all of the right elements (punctuation, numbers etc) but its encasing every letter within each word in an a tag not the word. so how do I use the regular expression to group the letters to a word?
from "(a tag open)t(a close)(a tag open)h(a close)(a tag open)i(a close)(a tag open)s(a close) (a tag open)i(a close)(a tag open)s(a close) (a tag open)w(a close)(a tag open)r(a close)(a tag open)o(a close)(a tag open)n(a close)(a tag open)g(a close)";
to :
"(a tag open)This(a close) (a tag open)is(a close) (a tag open)right(a close)";
then I'm making them clickable and I need to catch the click event and get the position on screen on the clicked word as I want to use the clicked event to make a tool tip show up just below the clicked word. thank you for your help.

item.setText(url_main + " was clicked.");
Log.d("item", url_main);
}
}
}

Latest code ,pls see link form github
message.setSpan(span, start, end, flags);
You need remove origin span before set new span.
Please see below
The onClick() of ClickableSpan is not working for URLSpan?
EDIT
You can capture any span click event by extends LinkMovementMethod

Edit for "android developer"
It is better way to add Handler property for LinkMovementMethodExt class.
You can capture all Spanned which are delivered as Message object.
Snip code in onTouchEvent method:
Message message = Handler.obtainMessage();
message.obj = buffer.getSpans(off, off, Spanned.class);//get all spanned
message.what = 111;//which value ,it is up to you
message.sendToTarget(); //send message to you target handler
You can handler expected spanned in you handler class. May be it is flexible way to handle .
Hope to help you.
Above textview text is <a href='/a'>aaaa</a>123456<a href='/b'>bbbb</b>7890
I understand you requirement : Click 'aaaa',you want get its href value '/a', click 'bbbb',get its href '/b'; Do not trigger default action which is opened in web browser.
If my understand is right, you can do like this:
Set LinkMovementMethod for textview, etc:textview.setMovementMethod(LinkMovementMethodExt.getInstance(handler, URLSpan.class));
Get interest span, here is URLSpan.
In you handler handleMessage method, you can do like this:
private Handler handler = new Handler() {
public void handleMessage(Message msg) {
int what = msg.what;
if (what == 100) {
Object[] spans = (Object[])msg.obj;
for (Object span : spans) {
if (span instanceof URLSpan) {
System.out.println(((URLSpan) span).getURL());
}
}
}
};
};
Download demo code
MainActivity has color property which you can assign which color value as you like.
How to do?
Step1, get current click span.
Step2, set BackgroundColorSpan for current click span

Assuming You want click individual words on the textview?. I din't understand the converts all letters to words in your comment.
The below can be used to click on individual works and it is displayed in a toast.
public class MainActivity extends Activity {
TextView _tv;
String[] each;
SpannableString ss1;
Button b;
EditText et;
String s;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

{
#Override

for(int i=0;i<s.length();i++)
{

}
for(int i=0;i<each.length;i++)
{
System.out.println("................"+each[i]);
ss1= new SpannableString(each[i]);
//StyleSpan boldSpan = new StyleSpan( Typeface.BOLD );
//spannable.setSpan( boldSpan, 41, 52, Spannable.SPAN_INCLUSIVE_INCLUSIVE );
ss1.setSpan(new MyClickableSpan(each[i]), 0, ss1.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
_tv.append(ss1);

with MainActivity containing the following:

private final static String TAG = "[MainActivity]:";

}
#Override
public void onBackPressed() {
if( mCustomKeyboard.isCustomKeyboardVisible() )

else this.finish();
}
}
Now, the problem is when I press a key on the custom keyboard, the cursor in the EditText is not moving, and the EditText itself is empty. I've read somewhere here that manufacturers are no longer required to propagate such events, or something to that effect. Is that the problem in my case? If not, what is?

The crux was in the line focusCurrent.getClass()!=EditText.class
As it turns out, the class is something like AppCompatEditText.
I remember someone at SO issuing a warning about this in comments. Now everything works.

CODE HELP: passing a string to another method, case statement fails with analysis

Good day All
I am struggling with this problem, I am not sure if I'm missing something obvious but the case statement/sorting method fails to return the correct result.
In short, the program recieves an input from a EditText (edtInput) and assigns it to
string temp in isValidNumeericSequence(string temp) {...}
where it gets tested for
1. if temp is empty
2. first character is a numeric value
3. the string contains anything except numbers and/or operators (operators specified in arrOperators)
The result from toast always refers to error_message 2, no matter what characters in the string, it always stays by error_message 2
IF I change the (temp == "" ) to (temp != ""), then it changes and sticks to error_message 1...
this might not be the most optimal method of calculating a equation, but its a simple start for me
p.s. If anything seems/looks abnormal, or irregular use of functions, please point them out, I would appreciate it...
I have tried debugging, but I seem to be missing something.

Thank you too #oguzhand and #Chris Stratton for the comments
edtInput.toString() is totally wrong!!! you need to use
edtInput.getText().toString() You are using edittext totally wrong...
Read this:
developer.android.com/reference/android/widget/EditText.html –
oguzhand
and
Indeed #oguzhand seems to have identified a primary issue, you are
using what is basically a "handy name" of the editText object rather
than the contents of its text field. – Chris Stratton
I simply replaced any edtInput.toString() with edtInput.getText().toString() and it worked perfectly
Thank you

Custom Android Keyboard Focus Issue

I'm currently working on developing a custom keyboard app that will be optimized for a device using a DPad as its primary input device.
My problem is that When the cursor is in the EditText field and you press down (e.g. KEYCODE_DPAD_DOWN), the keyboard view is not receiving focus and KeyEvents. Either nothing happens, or the element beneath the EditText in question receives focus.
Below is the relevant code.
Any help would be much appreciated. I've tried dissecting the SoftKeyboard example aswell as KeyboardView.java for hints without success.
Thanks,

Key events must be processed manually in the onKey method. To move the cursor, I use this:
if (primaryCode == KeyEvent.KEYCODE_DPAD_RIGHT) {
int position = connection.getTextBeforeCursor(Integer.MAX_VALUE, 0)
.length();
final CharSequence selected = connection.getSelectedText(0);
if (selected != null)
connection.commitText(
mComposing.substring(0,
mComposing.length() - selected.length()), 1);
else
connection.commitText(mComposing, 1);
connection.setSelection(position + 1, position + 1);
}

Hiding and showing a single Menu Button

I have a project for an Android class, so I'm still learning and this should be a basic question. We were given a tip calculator and already made some modifications, now we have to add a menu.
When it starts up, it will be in multi-person mode. Gives a text box and Text Field for how many people you want the bill split into. When you hit menu, it should show a Single person mode which eliminates a text box and text field. The menu then changes to show a multi-person mode button in the menu.
I've got everything to work except it's showing both buttons, I cannot figure out how to hide a button temporarily. The main error is:
Cannot invoke setVisibility(int) on the primitive type int
on the statement:
multiple_button.setVisibility(View.GONE);
I've tried every combination of hiding the button I can think of, and think that the above line is correct, but unsure of how make it work.
one_person_button = View.VISIBLE;
multiple_button = View.GONE;
I have this in the code, but it's not doing anything either.
Any help would be greatly appreciated.
edit: code. I've read through the link, but considering I don't have a OnPrepareOptions section, I need to re-read it

Post all of your relavent source code. Without it, we cannot give you specific advice about what is going wrong.
I can tell you though you'll be needing to override onPrepareOptionsMenu() and inside there you'll want to check which mode your in and make the proper button be visible. But you need to call setVisibility(View.VISIBLE); on a reference to the button widget, not on an int.
This page holds the answer to your questions.

try calling setVisibility with 8
