Get Sharedpreferences String Value From Adapter

I'm working now with Android Studio 'Java' and I have question about retrieving value from SharedPreferences. I have stored String value in SharedPreferences in the main activity.

Solution 1:

In your Adapter, you can retrieve SharedPreferences as follows:

SharedPreferencespreferences= context.getSharedPreferences("log11", Context.MODE_PRIVATE);
StringagentId= preferences.getString("agentId", "");

Solution 2:

Pass a context from your adapter constructor and retrieve SharedPreferences instance

publicConversationsAdapter(ConversationsAdapter.ConversationOnClickHandler conversationOnClickHandler, Context context) {
   mConversationOnClickHandler = conversationOnClickHandler;
   pref = context.getSharedPreferences("log11", Context.MODE_PRIVATE);
}

Solution 3:

Pass the context of the calling activity in your adapter through constructor and then use that context :

Context context;

publicConversationsAdapter(Context context,ConversationsAdapter.ConversationOnClickHandler conversationOnClickHandler){
   this.context=context;
   mConversationOnClickHandler = conversationOnClickHandler;
}

Now in your adapter you can do this:

SharedPreferencespreferences= context.getSharedPreferences("log11", Context.MODE_PRIVATE);
StringagentId= preferences.getString("agentId", "default_value");
