How should I create Country Code Text Input Box in React Native?
Please tell me the code for the component and the style sheet too.
I already create the code for the text input box, but I just stuck how should I add the country code in the input text box.
Here is the best third-party library for this:
https://www.npmjs.com/package/react-native-phone-number-input
Or If you do not want to use these then use a dropdown picker you can do it. In this, you have to take all country code data yourself.
https://www.npmjs.com/package/react-native-element-dropdown
I recommend you use the first one.
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.
I have a text gathered from API and it consists of custom syntax. I display it using TextView but I need to render special part of the text and convert those text into elements. An example of a text is below.
Oh, that's great idea! Check (user: someuser)'s answer for this.
You can as well look at (ref: a forum post title) or:
(ref: another forum post)
This is a hint for you! (hint: should be displayed as a mini icon
but when clicked, a tooltip should be opened)
Here is a spoiler for you.
---- spoiler ----
some spoiler. this text should not be displayed directly but it should be
converted to a button element. When the button is clicked, this text should
be shown
---- spoiler ----
So, I need to convert (user: someuser) into a link in the view which will be shown as "someuser" but when clicked, it will open a new intent. For (ref: topic) keyword, it's the same. When I hit spoiler, I want to make it a nice button indicating that it's a spoiler and when user clicks, it will expand.
How can I parse this text and show correctly in a view? I don't have problem with parsing but my problem is displaying those elements in the view.
Methods I Tried
I tried WebView instead of TextView thinking that I can convert those into HTML/Js but the performance was terrible. Although I use RecycleView and ViewHolder, WebView is simply an overkill. I need to use some kind of a TextView but with the elements I would like to have.
I also looked at custom HTML tag handling with TextView (thinking I can convert those legacy tags into html) but I failed to see how I can insert button for spoiler tag or insert custom elements like tooltip for hint.
Thank you!
Hi i am working on android soft keyboard. Normally labels displayed on
keys are single character as shown below
the above one is done by just using keylabel attribute of Key tag in Keyboard
to display whatever text we want on the key. But now my requirement is to display multiple characters on single key as shown below
I got one solution to this by using android:keyIcon but limitation is I need the color of characters to be configurable so that a user can change color of any character. Like 1 with red, | with blue, q with green. So it must be configurable to any color.That's why I skipped keyIcon property for displaying text on character.
So is there any way to set multiple characters on key.
The standard KeyboardView provided by android framework doesn't support displaying secondary text (or multiple characters). To achieve your desired functionality you need to subclass the KeyboardView(or simply View) and implement its onDraw method and draw directly to the Canvas.
You can check the source code of latinIME KeyboardView where its been implemented using hint label.
Also you need to write your own parser for parsing the Keyboard xml. you can check here how its done in LatinIME.
Understanding the complete package Keyboard in LatinIME will be very helpful for your requirement.
Hi I have done it with by taking reference of Customize the appearance of a <Key>
By playing with given code after three days i have got my solution.
I am wondering if there are any good options to implement a rich text editor in Android. Please note I am talking about a rich text editor that can be used in an Android application, not the one embedded in a web page using HTML and Javascript.
My requirements are:
Basic formatting (color, fonts, highlight, bold, italic, underline, etc.)
Hyperlinks
Inline images
Bullet lists and numbered lists
Inline table (only the contents inside a cell is editable, not the table structure)
As you can see, this is pretty much something quite similar to a typical RichEdit control on Windows.
Here are some efforts (investigation & prototyping) I have made so far:
Using WebView
I have tried using a WebView control to load an HTML fragment with one . The content becomes editable and as it is HTML, I suppose it can meet most of my requirements. But it has several issues:
(deadly) No text caret. The user will have no idea where his/her typed characters will be inserted.
The on-screen soft keyboard is not visible by default. There is a trick that the user has to long-press the Menu button to bring up the keyboard. But I think this is a very bad user experience. Besides, the screen layout is not properly rearranged and the text inserting point sometimes will be covered by the keyboard.
Using EditText
I have tried using the EditText control. It seems to support some level of rich text editing (color, fonts, bold, italic, underline, inline images, bullet lists). But I still cannot figure out how I can implement the following requirements:
Control the appereance of the bullet symbol (dot, circle, dash, arrow, star, etc.)
Numbered list (1., 2., 3., etc.)
Table
BTW, I have seen there are several *Span classes out there but I am not sure if they can be any help... And the http://developer.android.com does not provide much useful information about them.
So, how on earth can I implement a rich text editor on Android?
Can I extends the EditText and add my new functionalities? Or should I do something from scratch - extends the View and implement everything by myself? For later option (extending View), I actually even don't know how to show a text caret and blink it, not mentionging moving the caret with user typing.
I am desperate now... Any hints?
Thanks!

(EDIT)
After some further investigation, it looks like extending EditText would be my best bet. I somehow figured out how to use those Span classes and guess I should be able to do most of the tricks by using (extending) them.
For example, extending the BulletSpan and overriding drawLeadingMargin should give me the control of the bullet appereances. Extending the LeadingMarginSpan should help me on the numbered list.
As to the table, my initial plan is to extend the LineBackgroundSpan and draw all the table borders in the drawBackground override. However, I still need to figure out how to layout all the text in the table cells and properly handle the caret movement and selection. Suggestions?
I just published my rich text editor component under the Apache 2.0 license:

You can make use of any of the following libraries:-
https://github.com/commonsguy/cwac-richedit
https://github.com/chinalwb/Android-Rich-text-Editor
https://github.com/wasabeef/richeditor-android
https://github.com/irshuLx/Android-WYSIWYG-Editor
I would probably extend both EditText and TableLayout or at least end up using most of their source if there were big enough changes I needed to make.
Can you do the following:
Manually hold the contents in the EditText as your own model (ie by seperating and maintaing the content document and the view attributes as seperate entities).
Override the render (or draw method) to do custom layout on parts of the content document (part of your model) that handle non text characters (say bullets with particular attribute).
To me seems like if you have to muck about with the layout, are you better off writing it from scratch on your own. From what I remember the Edit text (and the richt text editor) is great for anything where you the data is pure text.
There is an open source EditText rich text editor called android-richtexteditor but the code was inexplicably deleted in r5. The code is still there in r4; just use svn to check out r4 or earlier to access it. The code appears to support italics, underline, color picker, text size, and more.
Also answered in these questions: 1, 2
Extend from EditText is a best choice for you, it support CharacterSpan and
ParagraphSpan.
See my App on the Google Play:

Check this open source Wordpress mobile application for android.It has very promising Richtexteditor based on Edittext.
You can download the source from here
