Instagram-like floating hearts view for android.
Demo APK: https://petersamokhin.com/files/projects/fh/fh.apk
- Add
jitpackrepo to your project-levelbuild.gradle:
allprojects {
repositories {
// other repos
maven { url 'https://jitpack.io' }
}
}- Add library to your dependencies:
dependencies {
implementation 'com.github.petersamokhin:floating-hearts-view:$ACTUAL_VERSION'
}Latest version: https://github.com/petersamokhin/floating-hearts-view/releases
Configure renderer:
val config = HeartsRenderer.Config(
5f, // The max amplitude of the flight along the X axis
0.15f, // Duration of the flying animation will be multiplied by this value (lower — faster)
2f // Heart size coefficient
)
heartsView.applyConfig(config)Or in your XML layout file:
<com.petersamokhin.android.floatinghearts.HeartsView
android:id="@+id/heartsView"
android:layout_width="match_parent"
android:layout_height="330dp"
app:x_max="3"
app:size_coeff="2.5"
app:floating_time_coeff="0.8" />Make your model:
// Get bitmap from image by URL
// or simply convert from drawable, etc
val image = "https://cdn.shopify.com/s/files/1/1061/1924/products/Thinking_Face_Emoji_large.png"
val byteArray = URL(image).readBytes()
val bitmap = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.size)
val model = HeartsView.Model(
0, // Unique ID of this image, used for Rajawali materials caching
bitmap // Bitmap image
)Let your image fly!
heartsView.emitHeart(model)Rajawali is the only one dependency. Inspired by Instagram/Snapchat/etc broadcasts.
On some devices / on some Android versions NullPointerException may happen after new Material() call in HeartsRenderer. This causes because GLES20.glGetString( GLES20.GL_EXTENSIONS ); is returning null.
To fix this simply do not call emitHeart in first 300-500 ms after activity start.
