Android 如何从循环中的微调器获取所有值

我试图创建一个表单来进行选择，但是我有一个具有多种可能性的微调器，因此微调器是自动生成的。这是我的脚本，在JSON数据循环的中间生成一个旋转器，而旋转子位于TeXVIEW循环下面：

StringRequest stringRequest = new StringRequest(Request.Method.GET, HttpUrl,
            new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {
                    progressDialog.dismiss();
                    try {
                        JSONObject obj = new JSONObject(response);
                        JSONArray gejalaArray = obj.getJSONArray("result");
                        for (int i = 0; i < gejalaArray.length(); i++) {
                            JSONObject gejalaObject = gejalaArray.getJSONObject(i);
                            final LinearLayout relativeLayout = (LinearLayout) findViewById(R.id.llMain);
                            final TextView textView = new TextView(getApplicationContext());
                            textView.setText(gejalaObject.getString("gejala"));
                            RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams
                                    (LinearLayout.LayoutParams.MATCH_PARENT,
                                            LinearLayout.LayoutParams.MATCH_PARENT);
                            textView.setLayoutParams(params);


                            final Spinner spinner = new Spinner(getApplicationContext());
                            spinner.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
                            final String[] personNames = {"Rahul", "Jack", "Rajeev", "Aryan", "Rashmi", "Jaspreet", "Akbar"};
                            ArrayAdapter arrayAdapter = new ArrayAdapter(getApplicationContext(), android.R.layout.simple_spinner_dropdown_item, personNames);
                            spinner.setAdapter(arrayAdapter);

                            relativeLayout.addView(textView);
                            relativeLayout.addView(spinner);
                        }
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            },
            new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    Toast.makeText(getApplicationContext(), error.getMessage(), Toast.LENGTH_SHORT).show();
                }
            });

    RequestQueue requestQueue = Volley.newRequestQueue(this);
    requestQueue.add(stringRequest);

有人能帮我吗？我做了好几次实验，但直到现在还是失败了。

谢谢大家。

在onClick函数中，您可以检索微调器的ArrayAdapter，然后循环其项：

BtnPro.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {
                ArrayAdapter adapter = ((Spinner)view).getAdapter();
                int n = adapter.getCount();
                for (int i = 0; i < n; i++) {
                    Toast.makeText(getApplicationContext(), adapter.getItem(i).toString(), Toast.LENGTH_SHORT);
                }
            }
        });

BtnPro.setOnClickListener（新视图.OnClickListener（）{
公共void onClick（视图）{
ArrayAdapter=（（微调器）视图）.getAdapter（）；
int n=adapter.getCount（）；
对于（int i=0；i

只需更改您希望在for循环中显示项目的方式

有关类似的解决方案，请参阅

BtnPro.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {
                ArrayAdapter adapter = ((Spinner)view).getAdapter();
                int n = adapter.getCount();
                for (int i = 0; i < n; i++) {
                    Toast.makeText(getApplicationContext(), adapter.getItem(i).toString(), Toast.LENGTH_SHORT);
                }
            }
        });
