Targetview to menu in Action bar

Hi Asykur,

For your case, you only need to get the MenuItem view and send it by 'targetView' function to your BubbleShowCaseBuilder. To get the MenuItem view from your Activity, you have to do the following lines:

val view = findViewById<ActionMenuItemView>(R.id.action_item_id) //where 'action_item_id' is the id of the MenuItem set on your xml menu file. 
BubbleShowCaseBuilder(this) //Activity instance
                .title("foo") //Any title for the bubble view
                .targetView(view) //View to point out
                .show() //Display the ShowCase

If you have any problem with this, let me know and I will be glad to help you.

Sorry for the delay.

Here is 👍 java.lang.RuntimeException: Unable to start activity ComponentInfo{com.vyas.pranav.studentcompanion/com.vyas.pranav.studentcompanion.ui.activities.SetUpActivity}: java.lang.IllegalArgumentException: Parameter specified as non-null is null: method kotlin.jvm.internal.Intrinsics.checkParameterIsNotNull, parameter targetView at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2951) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:3086) at android.app.servertransaction.LaunchActivityItem.execute(LaunchActivityItem.java:78) at android.app.servertransaction.TransactionExecutor.executeCallbacks(TransactionExecutor.java:108) at android.app.servertransaction.TransactionExecutor.execute(TransactionExecutor.java:68) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1816) at android.os.Handler.dispatchMessage(Handler.java:106) at android.os.Looper.loop(Looper.java:193) at android.app.ActivityThread.main(ActivityThread.java:6718) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:493) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:858) Caused by: java.lang.IllegalArgumentException: Parameter specified as non-null is null: method kotlin.jvm.internal.Intrinsics.checkParameterIsNotNull, parameter targetView at com.elconfidencial.bubbleshowcase.BubbleShowCaseBuilder.targetView(Unknown Source:2) at com.vyas.pranav.studentcompanion.ui.activities.SetUpActivity.showInstruction(SetUpActivity.java:73) at com.vyas.pranav.studentcompanion.ui.activities.SetUpActivity.onCreate(SetUpActivity.java:51) at android.app.Activity.performCreate(Activity.java:7144) at android.app.Activity.performCreate(Activity.java:7135) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1271) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2931) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:3086)  at android.app.servertransaction.LaunchActivityItem.execute(LaunchActivityItem.java:78)  at android.app.servertransaction.TransactionExecutor.executeCallbacks(TransactionExecutor.java:108)  at android.app.servertransaction.TransactionExecutor.execute(TransactionExecutor.java:68)  at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1816)  at android.os.Handler.dispatchMessage(Handler.java:106)  at android.os.Looper.loop(Looper.java:193)  at android.app.ActivityThread.main(ActivityThread.java:6718)  at java.lang.reflect.Method.invoke(Native Method)  at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:493)  at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:858) 

I have double checked about Id and it is same, I am using Butterknife to bind Toolbar and then set it as SupportActionBar
