custom adapter by retrofit 2.0 , but nothing show up
and I don't know if the problem from an adapter or the json file or
retrofit call, here the classes
MainActivity.java
public class MainActivity extends AppCompatActivity {
ListView listView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView = (ListView) findViewById(R.id.listView);
final ArrayList<tel_list> data = new ArrayList<tel_list>();
Retrofit retrofit = new
Retrofit.Builder().baseUrl("http://10.0.2.2";).addConverterFactory(GsonConverterFactory.create()).build();
TelService service = retrofit.create(TelService.class);
retrofit.Call<List<tel_list>> calls = service.getphones("telephones");
calls.enqueue(new Callback<List<tel_list>>() {
@Override
public void onResponse(Response<List<tel_list>> response, Retrofit
retrofit) {
TelAdapter adapter = new TelAdapter (MainActivity.this,
R.layout.list_item, data);
listView.setAdapter(adapter);
}
@Override
public void onFailure(Throwable t) {
}
});
}
}
TelAdapter.java
public class TelAdapter extends ArrayAdapter<tel_list> {
static Context context;
static int layoutResourceId;
private List<tel_list> data = null;
public TelAdapter(Context context,int layoutResourceId, List<tel_list>
data) {
super(context, layoutResourceId, data);
this.layoutResourceId = layoutResourceId;
this.context = context;
this.data = data;
}
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
TelHolder holder;
if (row == null) {
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
row = inflater.inflate(layoutResourceId, parent, false);
holder = new TelHolder();
holder.names = (TextView) row.findViewById(R.id.names);
holder.numbers = (TextView) row.findViewById(R.id.numbers);
row.setTag(holder);
} else {
holder = (TelHolder) row.getTag();
}
tel_list telephnoes = data.get(position);
holder.names.setText(telephnoes.getName());
holder.numbers.setText(telephnoes.getName());
return row;
}
static class TelHolder {
TextView names;
TextView numbers;
}
}
