I have some text in a list view. The format of each text contains a (1 or more) user's name inside as in:
This is a message for #[Joe Bloggs](id:100), hi how are you, from #[John Doe](id:50). I am fine.
I need to replace it with the following:
This is a message for #Joe Bloggs, hi how are you, from #John Doe. I am fine.
When you click on the user's name it should open an activity passing in the user's id.
What is the REGEX and logic that i need to do this operation, and what is the most efficient way of extracting the username and id, and replacing the text with the user's name in a clickable spannable text to open the activity with the user's id.
Bearing in mine, this is in a list view.
Thanks.

I'm currently doing a project from one of my subjects in my university. I'm about to do an attendance app that checks if the professors are present, late, or absent in the room based on the schedule. I made an app in an android studio which uses radio groups and radio buttons that will change the text in the text view which will show if the professors attendance status. I'm thinking of making a button that will upload the text views with the attendance statuses to a website which holds the data(database).
I'm not used to programming in the android studio that is why I would like to know if a way to upload the text views on a website. Thanks
It's quite simple, You have to create Weg api that you can call from the android mobile application and pass the current status of the professor or the whatever you want to pass on the server. That api will update the database as per whatever you have passed from the mobile application.
Also, One more thing that you can not pass the text view, you just need to pass the text of that view.
I hope, you will get answer from this.
Happy coding...
Assign value of textview to a string variable.
And use this string in your api to pass data.
For example if you have a textview with name teacher, you can get its value using this line.
String st_teacher = teacher.getText();
Now use that st_teacher value in your api to upload data.
I want to dynamically create two editText fields side by side, store information in them and delete whenever I need to.
Right now i have static fields, so it looks like this
Left ones have id siteName1, siteName2... right ones have id siteURL1, siteURL2... Also I have two buttons - Save and Load.
prefsEditor.putString("siteName1_txt", siteName1.getText().toString());
prefsEditor.putString("siteURL1_txt", siteURL1.getText().toString());
and so on...
siteName1.setText(myPrefs.getString("siteName1_txt", "").toString());
siteURL1.setText(myPrefs.getString("siteURL1_txt", "").toString());
and so on...
My app is voice controlled, so when I say command, it checks if I have right website name and opens it.
if (commandList.contains(siteNames[i].getText().toString())) {
mWebView.loadUrl("http://www." + siteURLs[i].getText().toString());
mWebView.setVisibility(View.VISIBLE);
}
Website names nad URLs are put to strings. So my question is - can I add two editTexts and delete them dynamically. Can I save information in them, so when I close and open app - info is saved. Thank you for your time.
I have implemented search dialog and online search suggestion. But I want when user click on suggestion to copy string from suggestion list to search dialog and when user click on search button to start searching. Now when user click on suggestion searching is automatic start.
Take a look at http://developer.android.com/guide/topics/search/adding-custom-suggestions.html#RewritingQueryText which lists 3 different approaches to do this as per below:
1) Add the android:searchMode attribute to your searchable configuration with the "queryRewriteFromText" value. In this case, the content from the suggestion's SUGGEST_COLUMN_TEXT_1 column is used to rewrite the query text.
2) Add the android:searchMode attribute to your searchable configuration with the "queryRewriteFromData" value. In this case, the content from the suggestion's SUGGEST_COLUMN_INTENT_DATA column is used to rewrite the query text. This should only be used with URI's or other data formats that are intended to be user-visible, such as HTTP URLs. Internal URI schemes should not be used to rewrite the query in this way.
3) Provide a unique query text string in the SUGGEST_COLUMN_QUERY column of your suggestions table. If this column is present and contains a value for the current suggestion, it is used to rewrite the query text (and override either of the previous implementations).
I have an android app which displays quotes and have navigation to go to next quote and so on. would like to add "Save Quote As favourite" based on users selection of particular quote.
Once user saves Fav quotes and wants to see those quotes only, app should show those quotes.
Currently app reads the quotes from XML file. Let me know if any more information is required to understand the problem.
I would provide every quote with an ID (int). Whenever the user selects a quote to be a favourite, that ID is saved to a Set of integers. Later on if user decides to show favourites, you fetch all quotes with your IDs from the Set and show them in a appropriate view, for example a ListView
If you have a Quote class or something like that, you might as well put them in a collection whenever user decide his favourites, and show them in a ListView with a custom adapter.
I have a working android app using TextView, some formatting (line breaks, rows of dashes) and Linkify to generate a primitive "ListView-like" display with clickable URLs in each "row". I'd like to move up to a real ListView, but I'm just not finding the sample/explanation that I need to take that next step.
I have successfully reproduced the HelloListView sample, starting with the hardcoded string array, and moving to a string array defined in my res/values/strings.xml. I've taken one small step toward my goal by adding my HttpClient code to retrieve a set of data from a service, parse the results into a String Array and feed that into setListAdapter() such that my text and links show up as text-only in ListView items.
I want to move to the next step which is to make each "row" in my ListView launch the browser to the URL contained in the data, either by
(A) clicking anywhere in the row, or
(B) clicking a hyperlink displayed within the row data
For option (A), it appears that I need to have my onItemClick() method issue an intent that launches the browser. That's straightforward, but I don't get how to associate the URL with the item (currently its just one part of the string content for each "row" of text). How do I separate my URL from the rest of the text, such that I can launch a browser to the corresponding URL? Do I need to replace my String Array with an array of custom objects?
For option (B), can I use Linkify? It seems that my string array elements get converted to individual TextViews (inferring from the way the Toast text is generated in the HelloListView sample). Do I have access to that TextView to run Linkify against? Do I need to replace my String Array with a TextView Array and run Linkify myself? Am I completely off base?
Thanks to anyone who can help explain back to me what I'm trying to do, in a way that helps to find my way around the SDK, samples and other helps!
How do I separate my URL from the rest of the text, such that I can launch a browser to the corresponding URL?
Use a regular expression (java.util.regex) to find the URL.
For option (B), can I use Linkify?
Yes.
Do I have access to that TextView to run Linkify against?
Yes. Override getView() in your ArrayAdapter. Chain to the superclass and get your TextView from the result of super.getView().
Even better would be to use Linkify on your strings before putting them in the array in the first place.
Do I need to replace my String Array with a TextView Array and run Linkify myself?
No, and that is really not a good idea. Here is a free excerpt from one of my books that goes into more detail on tailoring the individual rows of a ListView, in case this helps.
