Usage

Gradle

Add it in your app build.gradle at the end of repositories:

dependencies {
    implementation 'me.samlss:lighter:1.0.3'
}

Maven

<dependency>
  <groupId>me.samlss</groupId>
  <artifactId>lighter</artifactId>
  <version>1.0.3</version>
  <type>pom</type>
</dependency>

Code

You can specify that the highlighted root view is attached to the activity or viewgroup,

you can use the below code to specify:

Lighter with(Activity activity) //will use activity.getWindow().getDecorView as the root view, so it will display in full screen 
    
Lighter with(ViewGroup rootView) //will use the 'rootView' as the root view

Complete call:

 Lighter.with(activity)
                .addHighlight(new LighterParameter.Builder()
                                .setHighlightedViewId(R.id.vp_btn_1)
                                .setTipLayoutId(R.layout.layout_tip_1)
                                .setLighterShape(new RectShape(5, 5, 30))
                                .setTipViewRelativeDirection(Direction.BOTTOM)
                                .setTipViewRelativeOffset(new MarginOffset(150, 0, 30, 0))
                                .build())
                .addHighlight(new LighterParameter.Builder()
                        .setHighlightedViewId(R.id.vp_btn_2)
                        .setTipLayoutId(R.layout.layout_tip_2)
                        .setLighterShape(new RectShape(5, 5, 30))
                        .setTipViewRelativeDirection(Direction.TOP)
                        .setTipViewRelativeOffset(new MarginOffset(-400, 0, 0, 30))
                        .build())
                .show();

When you need to display multiple highlight views at once, call addHighlight(LighterParameter...lighterParameters)

Lighter.with(activity)
                .addHighlight(
                        //Show two at a time
                        new LighterParameter.Builder()
                                .setHighlightedViewId(R.id.vp_btn_1)
                                .setTipLayoutId(R.layout.layout_tip_1)
                                .setLighterShape(new RectShape(5, 5, 30))
                                .setTipViewRelativeDirection(Direction.BOTTOM)
                                .setTipViewRelativeOffset(new MarginOffset(150, 0, 30, 0))
                                .build(),

                        new LighterParameter.Builder()
                                .setHighlightedViewId(R.id.vp_btn_2)
                                .setTipLayoutId(R.layout.layout_tip_2)
                                .setLighterShape(new RectShape(5, 5, 30))
                                .setTipViewRelativeDirection(Direction.TOP)
                                .setTipViewRelativeOffset(new MarginOffset(-400, 0, 0, 30))
                                .build())
                .show();

Direction

Refer to the below picture :

Offset

When you specify a direction(the default is left), the offset distance will be based on the direction you specify.

E.g:

Left: The values of topMargin & rightMargin will take effect

Right: The values of topMargin & leftMargin will take effect

Top: If the highlighted view is on the left side of the screen, the values of leftMargin & bottomMargin will take effect. Otherwise, the values of rightMargin & bottomMargin will take effect.

Bottom: If the highlighted view is on the left side of the screen, the values of leftMargin & topMargin will take effect. Otherwise, the values of rightMargin & topMargin will take effect.

Animation

You can set any animation for the tip view.
