ArrayAdapter initialization error (Android)

Question

I have written the following code snippet in my App:

public Fragment getItem(int position) {

    switch(position){
        case 0:
            LP_Events_Tab mEventsTab= new LP_Events_Tab();
            mList= (ListView) findViewById(R.id.event_list);
            String[] temp= {"1","2","3"};
            ArrayAdapter<String> arrayAdapter= new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, temp);
            return mEventsTab;

           /*Other cases*/
    }
    return null;
}

For case 0, I am using an array of strings named temp to initialize the ArrayAdapter . However, Android Studio redlines the ArrayAdapter initialization arguments: (this,android.R.layout.simple_list_item_1, temp) and thus, I cannot proceed. I do not see any error with these arguments but Android Studio does and hence, I am stuck.

Answer 1

Replace the following line of code inside your Fragment -

ArrayAdapter<String> arrayAdapter= new ArrayAdapter<String>(getContext(), android.R.layout.simple_list_item_1, temp);

Hope this helps, let me know if you need any more help.

Answer 2

The problem is with your Constructor of Adapter

ArrayAdapter(Context context, int resource, List<T> objects)

So make sure you are passing right parameters, in your case your first parameter is this which will not work other then in Activity. So pass either getContext or getActivity .

尝试用“ MainActivity.this”（或您拥有的任何类名）替换“ this”
