I am new to android. My challenge is to create an application which captures part of text from image and highlight captured text.
Ex:
Right now getting below result by using sample
But i need result as
highlight phone number, email and website and need to capture those fields from image. Is it possible to navigate website when user click on highlighted part of website?
Please help me. Thanks in advance.
If you are using the above library
then you will get below function in CaptureActivity
boolean handleOcrDecode(OcrResult ocrResult) {}
in this function you can filter the text that you want from overall text.
After filtering the data show custom dailog with mobile number and email.
And make it email clickable so it will redirect the user to website.

I want to add images in a text field/text form field in flutter. Whenever the user clicks the first button in the bottom navigation bar, the app will ask to pick an image and the image will display in the text field.
Like this:-
How Can I add one? (I am not talking about emoji)
ANY HELP OR IDEA WOULD BE APPRECIATED.
You can use RichTextEditor using rich_text_view plugin to support stylized text. Another option here is by using flutter_markdown to render images from Markdown.
In my project I am try to pick the Gallery images and Emoticons into the Edit Text, I want like chat application. I need to pick the multiple Gallery images and add into the Edit Text field here with I attach my example image
You cant type messages with images inside the edittext for that fact that it wont scroll up or scroll left when editText is full.
solution:
what you need to do is create a string equivalent of the image
example:
:) = for happy face
:( = sad face
etc.
rr:)tttt:(
After you hit enter you can then parse your string and check for the emoticons in string form and delete it then replace it with picture.

Is it possible to display images with text in listview where i get mesages from webservice.
Yes it is possible of course. If you are using some complex way to get the messages from the webservice into the adapter, you must integrate this with sending these to the adapter.
Is it possible to send images to webservice and fetch them back in my listview. I am using .Net web service. I return XML from web service as my response.
Don not do that. Put your smileys in drawable or download them only once. Use your own tags inside text for smileys. For example when string :) occurs put a smiley.
I created a Db and added 4 fields to it: ID , Position, Special Character, URL. So i was able to display the corresponding specialcharcter when clicked. When i submit how can i convert that specialcharcter into smiley image. I tried to use functions like "Contains()" and "Replace". But nothing worked when i submited the message to listview. I get the same specialcharcter and text. I don get the image instead of specialcharcter. Please guide me
I suppose you are inserting the message inside a textView. You can use to replace the occurances of the special character with "<img src=\"the source\" />"
Use this to get the image shown setText(Html.fromHtml("hi how are you <img src=\"yourimage.png\" />"));
To replace :) with <img src=\"yourimage.png\" />.. use yourString.replaceAll(":)","<img src=\"yourimage.png\" />");
