如何使用Apps脚本从Google表格中获取数据？

Question

I want to create an android app where I am using google Apps Script for data storage(google sheet). Now I would like to fetch those rows whose particular column value are same. Here I am sending the code where I am searching those rows whose profession are same.

//Android code

public class FetchData extends AppCompatActivity {

private Button srch;
ArrayAdapter<String> adp1;
Spinner src_gen;
String n, gn;
EditText profession;
private ListView listView;
private ArrayList<MyDataModel> list=new ArrayList < > ();
MyArrayAdapter adapter;

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.fetch_data);

    srch = (Button) findViewById(R.id.srch);
profession = (EditText) findViewById(R.id.profession);
    src_gen = (Spinner) findViewById(R.id.src_gen);
p= profession.getText.tostring();

    srch.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            new FetchDataActivity().execute();
                       }
    });
    adapter = new MyArrayAdapter(ReadSingleData.this, list);
            listView = (ListView) findViewById(R.id.listView);
           listView.setAdapter(adapter);


}



class FetchDataActivity extends AsyncTask<Void, Void, Void> {

    ProgressDialog dialog;
    int i;

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        dialog = new ProgressDialog(FetchData.this);
        dialog.setTitle("Please wait...");
        dialog.setMessage("Fetching your values");
        dialog.show();

    }

    @Nullable
    @Override
    protected Void doInBackground(Void... params) {

        JSONObject jsonObject = fetchData (p);
        try {

            if (jsonObject != null) {

                if (jsonObject.length() > 0) {

                    JSONArray array = jsonObject.getJSONArray("records");

                    int lenArray = array.length();
                    if (lenArray > 0) {
                        for (; i < lenArray; i++) {

                            MyData data = new MyData ();

                            JSONObject object = array.getJSONObject(jIndex);

                           String name = object.getString("name");
                           String ph = object.getString("phone");

                            data.setName(name);
                            data.setPhone(ph);
                            list.add(data);
                                                        }

        } else {

Answer 1

Change your function code with the following.

var prof = sheet.getDataRange().getValue();
for (var i = 1; i <= prof.length; i++) {
    if (prof[i][2] == profession) { // If your professor name in first column use 0
       tdata.push(prof[i][0]);      
    }
}
