StepView

A simple animated step view for Android. Backward and forward animations is supported.

Usage

Add mavenCentral() to repositories block in your gradle file.
Add implementation 'com.github.shuhart:stepview:1.5.1' to your dependencies.
Add StepView into your layouts or view hierarchy.

Supported animations:

Name	Preview
`ANIMATION_LINE`
`ANIMATION_CIRCLE`
`ANIMATION_ALL`
`ANIMATION_NONE`
`ANIMATION_ALL and all next circles enabled`

In ANIMATION_CIRCLE and ANIMATION_NONE examples the line color remains the same. You can achieve this by specifying: app:doneStepLineColor="@color/stepview_line_next"

Usage:

Specify steps with xml attribute:

	app:steps="@array/steps"

	stepView.setSteps(List<String> steps);

Or Specify numbers of steps so that only circles with step number are shown:

	app:stepsNumber="4"

	stepView.setStepsNumber(4);

Styling:

<com.shuhart.stepview.StepView
	android:id="@+id/step_view"
	android:layout_width="match_parent"
	android:layout_height="wrap_content"
	android:padding="16dp"
	app:sv_selectedCircleColor="@color/colorAccent"
	app:sv_selectedTextColor="@color/colorAccent"
	app:sv_stepLineWidth="1dp"
	app:sv_stepPadding="4dp"
    app:sv_nextTextColor="@color/colorAccent"
	app:sv_nextStepLineColor="@color/colorAccent"
	app:sv_doneCircleColor="@color/colorAccent"
	app:sv_doneStepLineColor="@color/colorAccent"
	app:sv_doneCircleRadius="12dp"
	app:sv_selectedCircleRadius="12dp"
	app:sv_selectedStepNumberColor="@color/colorPrimary"
	app:sv_stepViewStyle="@style/StepView"
	app:sv_doneStepMarkColor="@color/colorPrimary"
	app:sv_stepNumberTextSize="12sp"
	app:sv_animationType="Line"
  app:sv_typeface="@font/roboto_italic"/>

or instantiate and setup it in runtime with handy state builder:

    stepView.getState()
            .selectedTextColor(ContextCompat.getColor(this, R.color.colorAccent))
            .animationType(StepView.ANIMATION_CIRCLE)
            .selectedCircleColor(ContextCompat.getColor(this, R.color.colorAccent))
            .selectedCircleRadius(getResources().getDimensionPixelSize(R.dimen.dp14))
            .selectedStepNumberColor(ContextCompat.getColor(this, R.color.colorPrimary))
            // You should specify only stepsNumber or steps array of strings.
            // In case you specify both steps array is chosen.
            .steps(new ArrayList<String>() {{
                add("First step");
                add("Second step");
                add("Third step");
            }})
            // You should specify only steps number or steps array of strings.
            // In case you specify both steps array is chosen.
            .stepsNumber(4)
            .animationDuration(getResources().getInteger(android.R.integer.config_shortAnimTime))
            .stepLineWidth(getResources().getDimensionPixelSize(R.dimen.dp1))
            .textSize(getResources().getDimensionPixelSize(R.dimen.sp14))
            .stepNumberTextSize(getResources().getDimensionPixelSize(R.dimen.sp16))
            .typeface(ResourcesCompat.getFont(context, R.font.roboto_italic))
            // other state methods are equal to the corresponding xml attributes
            .commit();

Change a step:

    // Passing 'true' triggers an animation if enabled.
    // Animation would run if a difference between current and next is 1.
    stepView.go(step, true);

If you want to mark last step with a done mark:

	stepView.done(true);

If you want to allow going back after that, you should unmark the done state:

	stepView.done(false)

You can set a step click listener:

    stepView.setOnStepClickListener(new StepView.OnStepClickListener() {
        @Override
        public void onStepClick(int step) {
            // 0 is the first step
        }
    });

See the sample for additional details.

If you want a custom typeface you should add font files to the resource folder "font" and reference any in xml layout. Alternatively you can specify typeface using the state builder in your code. Look into the sample for additional details on that.

You can enable view to draw remained step circles with a specified color. In xml:

<com.shuhart.stepview.StepView
	android:id="@+id/step_view"
	android:layout_width="match_parent"
	android:layout_height="wrap_content"
	android:padding="16dp"
	app:sv_nextStepCircleEnabled="true"
	app:sv_nextStepCircleColor="@color/gray"/>

In java:

    stepView.getState()
        .nextStepCircleEnabled(isChecked)
        .nextStepCircleColor(Color.GRAY)
        .commit();
