how to output data from xampp to Textview-CodePudding

the code below I have successfully displayed the data but using the recyclerView. I want to ask how to display data if using Textview?

private void loadDataMahasiswa() {
        progress = new ProgressDialog(this);
        progress.setCancelable(false);
        progress.setMessage("Loading ...");
        progress.show();

        String nip = editTxtnip.getText().toString();
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(URL)
                .addConverterFactory(GsonConverterFactory.create())
                .build();
        LoginAPI api = retrofit.create(LoginAPI.class);
        Call<Value> call = api.view3(nip);
        call.enqueue(new Callback<Value>() {
            @Override
            public void onResponse(Call<Value> call, Response<Value> response) {
                String value = response.body().getValue();
                progress.dismiss();
                if (value.equals("1")) {

                    results = response.body().getResult();
                    viewAdapter = new RecyclerViewAdapter3(Lihat_izin.this, results);
                    recyclerView.setAdapter(viewAdapter);
                }
            }

            @Override
            public void onFailure(Call<Value> call, Throwable t) {

            }
        });
    }

CodePudding user response：

If you are not using ArrayList of data then just add this line inside the response body See below code

public void onResponse(Call<Value> call, Response<Value> response) {
                String value = response.body().getValue();
                progress.dismiss();
                if (value.equals("1")) {
                    results = response.body().getResult();
                    viewAdapter = new RecyclerViewAdapter3(Lihat_izin.this, results);
                    recyclerView.setAdapter(viewAdapter);
                    String myData = response.body().toString(); // convert data to string
                    textView.setText(myData); // just add data to textView
                }
            }

Let me know if not solved yet
