How to use get getApplicationContext() in Adapter Class

Question

I am using Firebase to populate my BlogRecycleadapter with blog post and get Likes from Like Buttons but when device is offline and user press Like Button , then app crashes

Answer 1

Create a Adapter constructor and at the time of sending list data send one another parameter context from main class.

this in Fragment

 blogRecyclerAdapter = new BlogRecyclerAdapter(blog_list,getContext());
        blog_list_view.setLayoutManager(new LinearLayoutManager(container.getContext()));
        blog_list_view.setAdapter(blogRecyclerAdapter);

this is in adapter

public BlogRecyclerAdapter(List blog_list,Context context){
  this.blog_list = blog_list;
  this.context=context;
}

Then you can use this context as getApplicationContext(); in adapter class

disable button at the time of no internet.

if(!isNetworkAvailable()){
like_btn.setClickable(false); }

private boolean isNetworkAvailable() {
    ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
    return activeNetworkInfo != null && activeNetworkInfo.isConnected();
}
