How to set emoji by unicode in a textview?

Question

Hi I'd like to do the following:

??? unicode = U+1F60A
String emoji = getEmojiByUnicode(unicode)
String text = "So happy "
textview.setText(text + emoji);

to get this in my textview:

So happy 😊

How can I implement getEmojiByUnicode(unicode)?

What type should the unicode variable be? (String, char, int?)

Please note that I do NOT want to use Drawables!

Solution 1

Found a solution:

In my unicode I replaced 'U+' by '0x'

Example: replace 'U+1F60A' by '0x1F60A'

This way I got an 'int' like

int unicode = 0x1F60A;

Which can be used with

public String getEmojiByUnicode(int unicode){
    return new String(Character.toChars(unicode));
}

So Textview displays 😊 without Drawable

Try it with http://apps.timwhitlock.info/emoji/tables/unicode

Solution 2

You can directly use Emojis in string resources by using the decimal code like this:

😊

for example:

<string name="emoji">I am happy &#128522;</>

Solution 3

Note: For Kotlin

fun getEmoji(unicode: Int): String {
    return String(Character.toChars(unicode))
}

Solution 4

all of the credit to Kenneth Murerwa, whose answer solved my problem. just chiming in that just copy and paste what you get from the 'copy' button at https://emojipedia.org between good old quotation marks. Yeah, it's a noob point but hey, we're all noobs at the beggining 😂

val emoji = "\uD83D\uDE00 \uD83D\uDC4C"

and then you can add it to whatever string you need. It renders on the phone screen fine, though it won't show up in a println

println("👌")

Solution 5

I think I found the most straightforward solution. In my case, I wanted to add a fire (🔥) emoji to one of the chips in a chip group. I simply went to the Emojipedia Fire Entry¹, clicked on the copy button just below the emoji meaning, and literally just pasted it into my Kotlin code. Here is a code snippet of how it looked like after pasting.

val chip = Chip(context)
chip.text = "\uD83D\uDD25 New"

Here is how the code looks like once I run it on my device. I included the other chips as well 😉;

PS: I ran this on the latest version of Android Studio (Arctic Fox v. 2020.3.1). Results may differ with older versions.

[Pwnstar]

Is it possible to do this in strings.xml file ?

[Suragch]

@user1232726, This will depend on the user's phone including the emoji being used.

Can u please help to convert this "5794d5f7895fa10a8f8e1357" into the EMOJI.. @GilbertGiesbert ..Thanks...

What if I have the unicode in the form of string? How do I convert it into integer? Parsing makes in invalid as it removes 'F' from it.

[Chris - Jr]

Unfortunately it doesn't work with 32 bit Unicode, like U+1F1EF U+1F1F2. This value is outside the integer boundaries.

This is a good answer; to find the decimal code of an emoji, you can use something like quackit.com/character_sets/emoji
