Audiogram

Super lightweight audiowave progressbar written in Kotlin

Getting started

Add to your root build.gradle:

allprojects {
  repositories {

...

maven {
 url "https://jitpack.io" 
}
  
}
 
}

Add the dependency:

dependencies {

  compile 'com.github.alxrm:audiowave-progressbar:0.9' 
}

Attrs

attr format description
waveColor color with this color chunks will be filled
chunkWidth dimension every chunk will have this width
chunkHeight dimension maximum height all the chunks can be
minChunkHeight dimension minimum height all the chunks can be
chunkSpacing dimension spacing between chunks
chunkRadius dimension how much corners of every chunk will be rounded
progress float should be 0..100, it's float so you can easily animate this
animateExpansion boolean toggle the animated expansion

Note: If you are going to place this in a RecyclerView item, you have to set animateExpansion to false, otherwise you'll see an incredibly laggy scroll (check out the example)

In code

Settle the wave somewhere in your XML like this:

 <rm.com.audiowave.AudioWaveView
android:id="@+id/wave"
android:layout_width="match_parent"
android:layout_height="32dp"
android:layout_margin="16dp"
app:animateExpansion="false"
app:chunkWidth="3dp"
app:chunkHeight="24dp"
app:minChunkHeight="2dp"
app:chunkSpacing="1dp"
app:chunkRadius="1dp"
app:waveColor="@android:color/white"
/>

API

Set raw byte array asynchronously


// does downsampling in O(N) and shows the animation you see in a gif above (the inflation-like one)
  setRawData(byte[] data);

 // you also have the ability to listen, when does the downsampling complete
  setRawData(byte[] data, OnSamplingListener callback);

In case you have a scaled byte array you want to draw, i. e. an array whose size is the amount of chunks to draw


// instantly redraws the wave without async downsampling process
  setScaledData(byte[] scaledData);

Now you can use it like a Seekbar, it reacts on touches, just attach listener

 setOnProgressListener(OnProgressListener listener);

This listener has 3 methods like a built-in Seekbar

 void onStartTracking(float progress) {

// invokes when user touches the view
  
}

 void onStopTracking(float progress) {

// invokes when user releases the touch
  
}

 void onProgressChanged(float progress, boolean byUser) {

// invokes every time the progress's been changed
  
}

Contribution

There are some features(like better precision) I am about to implement, but a little bit later. If you'd like to help, you are always free to send pull requests or issues if you only want to suggest something

Note: All your pull requests should be written in kotlin

Resources

This library introduces dynamic control over vector drawables. Each and every aspect of a vector drawable can be controlled dynamically (via Java instances), using this library.

Features :

  • Control : Control every attribute related to path, group, vector and clip-path like color, alpha, strokeWdith, translation, scale, rotation etc.
  • Clip Paths : The library supports clip paths.
  • Trimming : The library allows trimming of path by using trimEnd, trimStart and trimOffset parameters.

A simple tree view with drag and drop capabilities.

A sample application showы how to realize immersive parallax effect header like Google Play app.

A custom GLSurfaceView to show image with ripple effect using OpenGL.

A powerful, flexible and easy to use Video and Image compression library for Android.

Image

It's usually said that "A picture is worth a thousand words". Images adds flair and beauty to our android apps, but we usaully have problems with these images due to thier large size. With SiliCompressor you can now compress and use your images more smoothly.

Video

Due to the high resolution of our Smartphone cameras and cameras from other devices, Video files have become large in size and thus difficult for it to be shared with others on social apps, social media and even when we need to upload it on our server. With SiliCompressor you can now compress your video file while maintaining it quality.

Fragmentation is a powerful library managing Fragment for Android.

It is designed for "Single Activity + Multi-Fragments" and "Multi-FragmentActivities + Multi-Fragments" architecture to simplify development process.
