How to add string array to ListView uing BaseAdapter?

Question

I wanted to create a list view and populate it with string array so I trid it with ArrayAdapter. This is my code.

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    String str[]={"A","S","S","P","S","S","P","Bl","Ra","M","a","a","c","s","s","ds"};

        ArrayAdapter<String> ad=new ArrayAdapter<>(this,android.R.layout.simple_list_item_1,str);

        ListView lv= (ListView)findViewById(R.id.lv);

 lv.setAdapter(ad);


    }
}

I was wondering that if BaseAdapter is superclass of ArrayAdapter then how to make same program with BaseAdapter?

just curious about how to do it with BaseAdapter. Can we do it with base adapter or we can only do it with ArrayAdapter only? — Ankit, May 10 '17 at 12:59
A custom class that `extends ArrayAdapter` is a custom adapter, but why? — OneCricketeer, May 10 '17 at 13:04

You have to implement a BaseAdapter like this:

public class CustomAdapter extends BaseAdapter {

private String[] data;

public CustomAdapter(String[] data) {
    this.data = data;
}

@Override
public int getCount() {
    return data.length;
}

@Override
public Object getItem(int position) {
    return data[position];
}

@Override
public long getItemId(int position) {
    return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    LayoutInflater li = (LayoutInflater) convertView.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View view = li.inflate(android.R.layout.simple_list_item_1, null);//set layout for displaying items
    TextView txt = (TextView) view.findViewById(android.R.id.text1);//get id for Text view
    txt.setText(data[position]);
    return view;
}
}
