Center Emoji in line

[Sese-Schneider]

Hi,

is it somehow possible to center an emoji in its line?

I manually set the lineheight via emojiTextView.setLineSpacing(0f, 1.5f);
Unfortunately the emoji "drops" and is not displayed centered.

I could not find any method in your files to do this.
If there is none could you add this in a future release please?

With kind regards,

Sebastian Schneider

I don't think you'll need to do anything in order to let it be centered. Maybe the line spacing is causing this dropping down effect.

[Sese-Schneider]

How can i fix this then?
I just set the emoji size, text size and linespacing according to doc. emoji is unicode added

[vanniktech]

Can you try 0.5.0-SNAPSHOT and see whether this changes anything. Note: setEmojiSize has been removed and instead lineHeight from TextView is used.

There are some other issues with the new line height settings. adding this:

android:lineSpacingMultiplier="2.5"
android:lineSpacingExtra="6dp"

causes this:

[vanniktech]

Interesting. Maybe support for those attributes have to be added too.

[justmobilize]

Might I suggest you leave both options in there? So if size is undefined it used the line height otherwise the emoji size?

I don't think line height will ever look right if changed, since it's all below the text. And I assume most people would want either centered or bottom aligned.

[vanniktech]

So using emojiSize if it's defined otherwise the line height?

[justmobilize]

I think that would be the best of both worlds.

[vanniktech]

@justmobilize would you like to submit a PR?

[Sese-Schneider]

@vanniktech how can i include this update into my gradle files?

[vanniktech]

Use the maven snapshot url and use 0.5.0-SNAPSHOT.

Unfortunately SNAPSHOT version has problems. When you leave the app and re-open it, the text box height becomes 0 and emojies vanish. Also emoji size has no effect still.

[vanniktech]

Which approach are you using?

[MobinHiq]

compile 'com.vanniktech:emoji-ios:0.5.0-SNAPSHOT' with a RecyclerView for messages. Look at this:

If the text is combined with Emojies then there is no problem, but if you just send emojies and you re-open the app then the line height gets 0 and as the image shows.

[vanniktech]

Hmm what does your xml layout declaration / java code look like? Try out the sample and just send an Emoji. In there it does work.

[MobinHiq]

Actually it works on Emulator with no problem! And if I change no non SNAPSHOT version then it would be fine but the emoji keyboard not closing on back press happens!

<com.vanniktech.emoji.EmojiTextView
android:id="@+id/textMessage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAlignment="textStart"
android:layout_gravity="start"
android:textStyle="normal"
android:textColor="@color/chatTextMainColor"
android:textSize="16sp" />

The code is exactly as your sample. I haven't add anything special.

[vanniktech]

Maybe the textStyle or textAlignment adding just emojis does work in the sample.

[MobinHiq]

Let me check more. The weird thing is that it doesn't have any problem in the emulator. Also if you remember in issue #138 and Ereza mentioned the same problem of line height becoming 0 and he thought he resolved it with removing the emoji size but it was not solved apparently.

[vanniktech]

Yup I do. I also yesterday briefly experimented with displaying the emoji in a bigger size when you only send one (similary to what Whatsapp & Slack does) and I also stumbled upon some problems. I definitely want this to get fixed before doing 0.5.0.

[MobinHiq]

That would be great if it's fixed soon. We plan to release and use your library in end of July so we would be really happy if it's fixed. But I will try to go around and test different cases to see if it's possible to fix it.

[vanniktech]

I'd fix it right away if the project I'm working on would require this library. Unfortunately priorities have changed recently and it's a complete side project.

I also created #148 for further discussion about the Emoji size potential.

[MobinHiq]

Excellent, we really appreciate your great work. Good luck.

[justmobilize]

I can also look into some of this. We are a handful of commits back (before the sizing started to change) and resizing single emojis (without text works).

[vanniktech]

I'd appreciate any help. I'm also waiting with 0.5.0 until this sizing is resolved.
