## Usage



### Simple usage



```java

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](https://github.com/KeepSafe/TapTargetView/issues/180)*



### Sequences



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



```java

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.
