Audio Widget Overlay View

Meet the Audio Widget Overlay View by Cleveroad

You know, guys, we have become a bit obsessed with music recently. See yourself by checking our previous work on the Audio Visualization View library. Since we wanted to create a companion to our equalizer and add to the collection of Android widgets, the idea to develop a nice and convenient audio widget was born almost immediately. So if you have already developed a music player and you feel that you want to make it even better, then you’re welcome to use our library and enjoy the results.

Also you can watch the animation of the Audio Widget Overlay on YouTube in HD quality.

Our invention can facilitate the user’s interaction with a music player and nicely decorate his device screen. Moreover, it’s really easy to integrate! Read our Case Study: Audio Widget Overlay View by Cleveroad to ensure that and find more of useful information.

Setup and usage

To use Audio Widget Overlay first add dependency to your project:

dependencies {
    compile 'com.cleveroad:audiowidget:0.9.0'
}

This library will add two new permissions to your manifest:

<!-- used for drawing widget. This permission must be granted before calling AudioWidget.show(). -->
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>

<!-- used for notifing user that he is about to remove widget when he drags it on remove widget icon. -->
<!-- This permission granted by default on Android 6.0+ devices. -->
<uses-permission android:name="android.permission.VIBRATE"/>

Then you can create new instance of widget using builder:

AudioWidget audioWidget = new AudioWidget.Builder(context)
        .lightColor(...)
        .darkColor(...)
        .expandWidgetColor(...)
        .progressColor(...)
        .progressStrokeWidth(...)
        .crossColor(...)
        .crossOverlappedColor(...)
        .crossStrokeWidth(...)
        .buttonPadding(...)
        .bubblesMinSize(...)
        .bubblesMaxSize(...)
        .shadowColor(...)
        .shadowRadius(...)
        .shadowDx(...)
        .shadowDy(...)
        .playDrawable(...)
        .pauseDrawable(...)
        .playlistDrawable(...)
        .prevTrackDrawale(...)
        .nextTrackDrawable(...)
        .defaultAlbumDrawable(...)
        .edgeOffsetXCollapsed(...)
        .edgeOffsetYCollapsed(...)
        .edgeOffsetXExpanded(...)
        .edgeOffsetYExpanded(...)
        .build();

Or you can use default configuration. Just call:

AudioWidget audioWidget = new AudioWidget.Builder(context).build();

Then you can use audio widget's controller to listen for events:

// media buttons' click listener
audioWidget.controller().onControlsClickListener(new AudioWidget.OnControlsClickListener() {
    @Override
    public boolean onPlaylistClicked() {
        // playlist icon clicked
        // return true to collapse widget, false to stay in expanded state
    }

    @Override
    public void onPreviousClicked() {
        // previous track button clicked
    }

    @Override
    public boolean onPlayPauseClicked() {
        // return true to change playback state of widget and play button click animation (in collapsed state)
        return true;
    }

    @Override
    public void onNextClicked() {
        // next track button clicked
    }

    @Override
    public void onAlbumClicked() {
        // album cover clicked
    }
});

// widget's state listener
audioWidget.controller().onWidgetStateChangedListener(new AudioWidget.OnWidgetStateChangedListener() {
    @Override
    public void onWidgetStateChanged(@NonNull AudioWidget.State state) {
        // widget state changed (COLLAPSED, EXPANDED, REMOVED)
    }

    @Override
    public void onWidgetPositionChanged(int cx, int cy) {
        // widget position change. Save coordinates here to reuse them next time AudioWidget.show(int, int) called.
    }
});

Using AudioWidget.Controller, you can set track's duration, current position or album cover. Also you can set current playback state using start(), pause() or stop() methods. See MusicService class for more info on how to use controller.

To show audio widget on screen call AudioWidget.show(int, int) method. To hide it call AudioWidget.hide() method. Very simple!

audioWidget.show(100, 100); // coordinates in pixels on screen from top left corner
...
audioWidget.hide();

But make sure that your app has permission to draw over another apps in Android 6.0+. You can do it like this (in Activity):

    ...
    
    // somewhere in your code
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && !Settings.canDrawOverlays(this)) {
        Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION, Uri.parse("package:" + getPackageName()));
        startActivityForResult(intent, OVERLAY_PERMISSION_REQ_CODE);
    }
    
    ...
    
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == OVERLAY_PERMISSION_REQ_CODE) {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && Settings.canDrawOverlays(this)) {
                // now you can show audio widget
            }
        }
    }
    
    ...
