From Splash screen to Onboarding where I have 3 slides, then to Dashboard activity which ends up crashing not going through to dashboard

I initialy had Radio player i.e RadioActivity, which was working perfectly
The problem
I later decided to have a dashboad as the main activity where you can click a button to take you to the RadioActivty. Now app keeps crashing after splashscreen
Find The Codes Below

How to retrieve data from firebase for if else condition in java

I tried to make a different condition based on firebase database data. for example if the "Status" field data has value "Aktif" then the marker color will change to blue and when the "Status" value change into "Nonaktif" then the marker color will change into red. I already to use this code, but when tried to run it have the problem "error: incompatible types: cannot be converted to Context".
So how can i fix this problem? i will put the database structure here Firebase structure

I recently started learning Java and decided to create an application. When registering, it shows the username in my database, but not in the application itself.I thought I had a problem with id but, no, everything is correct there. I've been looking for the second day and I just can't figure out what the problem is. Thanks in advance for solving the problem. What is the problem?

PostAdapter returning incorrect postids for posts

Introduced some code that makes my PostAdapter return the wrong postid when I Log it, and the post isn't being liked... I am not sure how to fix it. App doesn't crash or anything, but I am unsure how to fix it.
Post has three ImageViews, and when they are clicked on they change color. That before was happening as it is supposed to, but now it isn't working... App doesn't crash, like I said, but when I Log it, I get back the wrong postid.
Likes aren't being saved to correct posts, and comments aren't being recorded.
Can anyone advise me on why this is happening?

The problem is at
public Post post;
Whenever a row is rendered, its value is assigned to this one. When the user taps on another row, the adapter still uses this post to get the id.
Just simply get rid of the post and use position to access the item the user just tapped on.

This is because you are using setting a click listener in onbind which will overwrite the previous click listener so the post in that click listener will never be synced up correctly. You should move your click listeners to the viewholder instead. Or an easy fix is to use getItem(viewholder.adapterPosition) in the click listener
