no suitable constructor found for ArrayAdapter

问题

I'm getting the following error:

Error:(34, 53) error: no suitable constructor found for ArrayAdapter(AllStores,ListView,Response<List<Store>>)
constructor ArrayAdapter.ArrayAdapter(Context,int,int,List<String>) is not applicable
(actual and formal argument lists differ in length)
constructor ArrayAdapter.ArrayAdapter(Context,int,List<String>) is not applicable
(actual argument ListView cannot be converted to int by method invocation conversion)
constructor ArrayAdapter.ArrayAdapter(Context,int,int,String[]) is not applicable
(actual and formal argument lists differ in length)
constructor ArrayAdapter.ArrayAdapter(Context,int,String[]) is not applicable
(actual argument ListView cannot be converted to int by method invocation conversion)
constructor ArrayAdapter.ArrayAdapter(Context,int,int) is not applicable
(actual argument ListView cannot be converted to int by method invocation conversion)
constructor ArrayAdapter.ArrayAdapter(Context,int) is not applicable
(actual and formal argument lists differ in length)

And this is what I have tried:

        ArrayAdapter<String> stringArrayAdapter=new ArrayAdapter<String>(
                AllStores.this,
                lv,
                subprises);

I have also tried to replace the first parameter of ArrayAdapter with this, getApplicationContext() or context. Unfortunately it didn't worked. I have really no idea what I'm doing wrong.

Here below you can see my code if you want to see it:

AllStores.java:

public class AllStores extends Activity {
    private ListView lv;
    Context context;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_all_stores);
        lv = (ListView) findViewById(R.id.store_list);
        Response<List<Store>> subprises;
        try {
            subprises = new StoreService().getSubprises();
            Iterator it = subprises.body().iterator();
            ArrayAdapter<String> stringArrayAdapter=new ArrayAdapter<String>(
                    AllStores.this,
                    lv,
                    subprises);
        } catch (IOException e) {
            e.printStackTrace();
        } catch (ExecutionException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

回答1:

The ArrayAdapter<String> constructor doesn't accept ListView nor Response<List<Store>> and in your code you added them both

ArrayAdapter<String> stringArrayAdapter=new ArrayAdapter<String> AllStores.this, lv, subprises);

but it should take the Context, layout resource id and the List<String> or String[]. A simple adapter would be

ArrayAdapter<String> adapter = new ArrayAdapter<>(AllStores.this, android.R.layout.simple_list_item_1, your_string_array_or_list);

then you set that adapter to your ListView

lv.setAdapter(adatper);

If you want more complex adapter, you should create a custom ArrayAdapter. Check out this link
