Lightweight audiowave progressbar for Android

Step 1. Add the JitPack repository to your build file

Add it in your root settings.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Add it in your settings.gradle.kts at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url = uri("https://jitpack.io") }
		}
	}

Add to pom.xml

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.biocarl:audiowave-progressbar:0.9'
	}

	dependencies {
		implementation("com.github.biocarl:audiowave-progressbar:0.9")
	}

	<dependency>
	    <groupId>com.github.biocarl</groupId>
	    <artifactId>audiowave-progressbar</artifactId>
	    <version>0.9</version>
	</dependency>


                            
    libraryDependencies += "com.github.biocarl" % "audiowave-progressbar" % "0.9"


                            
    :dependencies [[com.github.biocarl/audiowave-progressbar "0.9"]]

Readme

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
