EmojiReactionView

An Android library to make Emoji Reactions on imageviews in a manner Instagram does this!.


Table of contents

Features

  • Design : The library tries to be reasonably close to the original Instagram's design.
  • Customization : Users can customize the look to a great extent easily and reliably.
  • Support for RecyclerView : It can easily be used with Recycler views.
  • Optimum performance : Efforts have been made to keep memory usage as small as possible.
  • Unharmed image : The library doesn't change/modify the image, so every modification of image as imageview is possible

Example

Below is the two sample for usage of the library:

Usage

Just add the following dependency in your app's build.gradle

repositories {
    maven {
        url 'https://dl.bintray.com/dev-ritik/EmojiReactionView/'
    }
}

dependencies {
    implementation 'com.ritik:emojireactionlibrary:1.0.2'
}

Add the following code in your xml file

<com.ritik.emojireactionlibrary.EmojiReactionView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@drawable/image"
        app:emojis="@array/emoji" />

where emoji is an array resource which is the address to all emojis to be in the panel like:


    <array name="emoji">
        <item>@drawable/em1</item>
        <item>@drawable/em2</item>
        <item>@drawable/em2</item>
    </array>

and for the home emoji, rename that to home, so that its resource id becomes R.drawable.home to override default home emoji originally set.

To get notified of when the emojis are clicked, you can use:

myImage.setOnEmojiClickListener(new ClickInterface() {
    @Override
    public void onEmojiClicked(int emojiIndex, int x, int y) {
        // emojiIndex is the index of the emoji being clicked (0 based)
        // x,y are the coordinates of the clicked position relative to the image 
        // (if x && y == -1 => changed by program(SetClickedEmojiNumber)
    }

    @Override
    public void onEmojiUnclicked(int emojiIndex, int x, int y) {
        // emojiIndex is the index of the emoji being clicked (0 based)
        // x,y are the coordinates of the clicked position relative to the image 
        // (if x && y == -1 => changed by program(SetClickedEmojiNumber)
    }
});

If you are struck somewhere, you can always check its usage in the sample app for Simple and RecyclerView usage.

With this all done and working, you have made to the default design!

Further customization

The library provides these attributes to modify default design to a custom one:

Attribute Description Type(Range) Default Value
emojis Set the emojis to be displayed in the panel animation reference
set_emoji Set the current selected emoji integer(>-1)(< noe*) (0 based) -1
home_Center_X Set the x coordinate of homeEmoji's center dimensions 30 * density
home_Center_Y Set the y coordinate of homeEmoji's center dimensions Height - 30 * density
home_side Set the side length of homeEmoji dimensions 50 * density
panel_center_X Set the x coordinate of the center of panel animation dimension or fraction [0%,100%] (w.r.t width)# width / 2
panel_center_Y Set the y coordinate of the center of panel animation dimension or fraction [0%,100%] (w.r.t height) Height - emojiSide / 2
panel_radius Set the radius of panel animation dimension min(Height,Width) / 2 - 20 * density
panel_emoji_side Set the side of emojis on the panel dimension 50 * density
emojis_rising_height Set the height of the rising emojis(to start disappearing) fraction [0%,100%] (w.r.t height)# Height / 2
emojis_rising_speed Set the speed per frame of the rising emojis dimension 10 * density
emojis_rising_number Set the number of emojis rising in rising emojis animation integer 24

noe = number of emojis. *# measurement from bottom
