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:0.7'
}

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

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: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 scaled byte array you want 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 seeking) 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
