Usage

Simple usage

TapTargetView.showFor(this,                 // `this` is an Activity
    TapTarget.forView(findViewById(R.id.target), "This is a target", "We have the best targets, believe me")
        // All options below are optional
        .outerCircleColor(R.color.red)      // Specify a color for the outer circle
	.outerCircleAlpha(0.96f)            // Specify the alpha amount for the outer circle
        .targetCircleColor(R.color.white)   // Specify a color for the target circle
        .titleTextSize(20)                  // Specify the size (in sp) of the title text
        .titleTextColor(R.color.white)      // Specify the color of the title text
        .descriptionTextSize(10)            // Specify the size (in sp) of the description text
        .descriptionTextColor(R.color.red)  // Specify the color of the description text
        .textColor(R.color.blue)            // Specify a color for both the title and description text
        .textTypeface(Typeface.SANS_SERIF)  // Specify a typeface for the text
        .dimColor(R.color.black)            // If set, will dim behind the view with 30% opacity of the given color
        .drawShadow(true)                   // Whether to draw a drop shadow or not
        .cancelable(false)                  // Whether tapping outside the outer circle dismisses the view
        .tintTarget(true)                   // Whether to tint the target view's color
        .transparentTarget(false)           // Specify whether the target is transparent (displays the content underneath)
        .icon(Drawable)                     // Specify a custom drawable to draw as the target
        .targetRadius(60),                  // Specify the target radius (in dp)
    new TapTargetView.Listener() {          // The listener can listen for regular clicks, long clicks or cancels
        @Override
        public void onTargetClick(TapTargetView view) {
            super.onTargetClick(view);      // This call is optional
            doSomething();
        }
    });

You may also choose to target your own custom Rect with TapTarget.forBounds(Rect, ...)

Additionally, each color can be specified via a @ColorRes or a @ColorInt. Functions that have the suffix Int take a @ColorInt.

Tip: When targeting a Toolbar item, be careful with Proguard and ensure you're keeping certain fields. See #180

Sequences

You can easily create a sequence of tap targets with TapTargetSequence:

new TapTargetSequence(this)
    .targets(
        TapTarget.forView(findViewById(R.id.never), "Gonna"),
        TapTarget.forView(findViewById(R.id.give), "You", "Up")
                .dimColor(android.R.color.never)
                .outerCircleColor(R.color.gonna)
                .targetCircleColor(R.color.let)
                .textColor(android.R.color.you),
        TapTarget.forBounds(rickTarget, "Down", ":^)")
                .cancelable(false)
                .icon(rick))
    .listener(new TapTargetSequence.Listener() {
        // This listener will tell us when interesting(tm) events happen in regards
        // to the sequence
        @Override
        public void onSequenceFinish() {
            // Yay
        }
        
        @Override
        public void onSequenceStep(TapTarget lastTarget, boolean targetClicked) {
            // Perform action for the current target
        }

        @Override
        public void onSequenceCanceled(TapTarget lastTarget) {
            // Boo
        }
    });

A sequence is started via a call to start() on the TapTargetSequence instance

For more examples of usage, please look at the included sample app.
