Getting Started

NOTE: v4.0 is a huge leap from v3.4 and offers much better flexibility. Please take note when migrating.

SnackProgressBarManager

Start by creating an instance of SnackProgressBarManager in your activity.
If possible, the root view of the activity should be provided and can be any type of layout.

private SnackProgressBarManager snackProgressBarManager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // always have one instance of SnackProgressBarManager only in the activity
    snackProgressBarManager = new SnackProgressBarManager(view)
            // (optional) set the view which will animate with SnackProgressBar e.g. FAB when CoordinatorLayout is not used
            .setViewToMove(floatingActionButton)
            // (optional) change progressBar color, default = R.color.colorAccent
            .setProgressBarColor(R.color.colorAccent)
            // (optional) change background color, default = BACKGROUND_COLOR_DEFAULT (#FF323232)
            .setBackgroundColor(SnackProgressBarManager.BACKGROUND_COLOR_DEFAULT)
            // (optional) change text size, default = 14sp
            .setTextSize(14)
            // (optional) set max lines, default = 2
            .setMessageMaxLines(2)
            // (optional) register onDisplayListener
            .setOnDisplayListener(new SnackProgressBarManager.OnDisplayListener() {
                @Override
                public void onShown(SnackProgressBar snackProgressBar, int onDisplayId) {
                    // do something
                }

                @Override
                public void onDismissed(SnackProgressBar snackProgressBar, int onDisplayId) {
                    // do something
                }
            });
}

SnackProgressBar

Create a SnackProgressBar by calling the following examples.

// TYPE_NORMAL
SnackProgressBar normalType = new SnackProgressBar(
        SnackProgressBar.TYPE_NORMAL, "TYPE_NORMAL - " + queue)
        // (optional) allow user input, default = FALSE
        .setAllowUserInput(true)
        // (optional) allow user swipe to dismiss, default = FALSE
        .setSwipeToDismiss(true)
        // (optional) set icon
        .setIconResource(R.mipmap.ic_launcher);
// create a bundle and attach to snackProgressBar which can be retrieved via OnDisplayListener
Bundle bundle = new Bundle();
bundle.putInt("queue", queue);
normalType.putBundle(bundle);

// TYPE_NORMAL with action
SnackProgressBar normalTypeWithAction = new SnackProgressBar(
        SnackProgressBar.TYPE_NORMAL, "TYPE_NORMAL - If the action text is too long, a higher layout is used.")
        // set action button
        .setAction("DISMISS", new SnackProgressBar.OnActionClickListener() {
            @Override
            public void onActionClick() {
                // do something
            }
        });

// TYPE_HORIZONTAL
SnackProgressBar horizontalType = new SnackProgressBar(
        SnackProgressBar.TYPE_HORIZONTAL, "TYPE_HORIZONTAL - Loading...")
        // (optional) set the type of progressBar, default = FALSE
        .setIsIndeterminate(false)
        // (optional) set max progress, default = 100
        .setProgressMax(100)
        // (optional) show percentage, default = FALSE
        .setShowProgressPercentage(true);

// TYPE_CIRCULAR with action
SnackProgressBar circularTypeWithAction = new SnackProgressBar(
        SnackProgressBar.TYPE_CIRCULAR, "TYPE_CIRCULAR - Loading...")
        .setIsIndeterminate(true)
        .setAction("DISMISS", new SnackProgressBar.OnActionClickListener() {
            @Override
            public void onActionClick() {
                // do something
            }
        });

Note that action can be inserted in every type of SnackProgressBar.

Show

Show the SnackProgressBar by calling:

// LENGTH_SHORT, LENGTH_LONG, LENGTH_INDEFINITE or other positive millis can be used
snackProgressBarManager.show(snackProgressBar, SnackProgressBarManager.LENGTH_LONG);

To enable callback for OnShown and OnDismissed, include a onDisplayId when calling show().

int onDisplayId = 100;
snackProgressBarManager.show(snackProgressBar, SnackProgressBarManager.LENGTH_LONG, onDisplayId);

Or you can add the SnackProgressBar into memory and call it later.

// it is stored in HashMap, so storeId must be unique for each SnackProgressBar, else it will be overwritten
int storeId = 100;
snackProgressBarManager.put(snackProgressBar, storeId);
snackProgressBarManager.show(storeId, SnackProgressBarManager.LENGTH_LONG);

Calling show() will put the SnackProgressBar into a queue, which will be shown after those in queue before it has been dismissed
(by user action or set showDuration).

Note: If LENGTH_INDEFINITE is specified for the queued SnackProgressBar, adding a new SnackProgressBar into the queue will cause
the previous SnackProgressBar to use LENGTH_SHORT instead, dismissed and then show the new SnackProgressBar.

Update

Calling show() will always animate the hiding and showing of SnackProgressBar between queue. Use updateTo() instead to modify the
displayed SnackProgressBar without animation. To modify the currently showing SnackProgressBar:

// get the currently showing indeterminateType and change the message
SnackProgressBar snackProgressBar = snackProgressBarManager.getLastShown();
snackProgressBar.setMessage("new message");
// calling updateTo() will not hide and show again the SnackProgressBar
snackProgressBarManager.updateTo(snackProgressBar);

Dismiss

Call snackProgressBarManager.dismiss() to dismiss the currently showing SnackProgressBar. The next SnackProgressBar in queue will be shown.
Call snackProgressBarManager.dismissAll() to dismiss the currently showing SnackProgressBar and clear all other SnackProgressBars in queue.

Set Progress

Call snackProgressBarManager.setProgress() to set the progress of ProgressBar.
