需要：我想在第一个微调器中设置 valueone 数组标题，在第二个微调器中设置 valuetwo 数组标题。 输出： 对于第一个微调器，我想加载蓝色和红色。对于第二个微调器，我想加载 X 和 XL。请帮我解决 for 循环。

我的 for 循环：

   try {

            JSONObject jsonobjectone = new JSONObject(result);
            Log.e("IMAGE URL", jsonobjectone.getString("producturl"));
            JSONArray jsonarray = jsonobjectone.getJSONArray("options");

            for (int i = 0; i < jsonarray.length(); i++) {
                jsonobjectone = jsonarray.getJSONObject(i);
                String spinnertitle = jsonobjectone.optString("default_title").toString();
                spinone.setPrompt("Select" + " " + spinnertitle);
                Log.e("spinnertitle", spinnertitle);
                JSONArray json_second = jsonobjectone.getJSONArray("values");
                // JSONArray json_second = new JSONArray("values");

                for (int j = 0; j < json_second.length(); j++) {
                    JSONObject jsonObject = json_second.getJSONObject(j);
                    String title = jsonObject.optString("title").toString();
                    Log.e("option_A", title);
                    colorlist.add(title);
                }
                ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                        android.R.layout.simple_spinner_item, colorlist);
                adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
                spinone.setAdapter(adapter);

                JSONArray json_seconds = jsonobjectone.getJSONArray("values1");
                for (int j = 0; j < json_second.length(); j++) {
                    JSONObject jsonObject = json_seconds.getJSONObject(j);
                    String colortitle = jsonObject.optString("title").toString();
                    Log.e("option_B", colortitle);
                    sizelist.add(colortitle);
                }
                ArrayAdapter<String> adaptertwo = new ArrayAdapter<String>(this,
                        android.R.layout.simple_spinner_item, sizelist);
                adaptertwo.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
                spintwo.setAdapter(adaptertwo);

            }

Answer 1

这是一个可能的解决方案：

 public class Example extends Activity {

    private ArrayList<Srtring> spinnerValueOne;
    private ArrayList<Srtring> spinnerValueTwo;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        spinnerValueOne = new ArrayList<>();
        spinnerValueTwo = new ArrayList<>();

        Spinner spinner1 = (Spinner) findViewById(R.id.spinner1);
        Spinner spinner2 = (Spinner) findViewById(R.id.spinner2);

        // get your json response
        String response = ....;
        JSONArray jArray = new JSONArray(response);
        JSONArray valueOneArray = jArray.getJsonArray("valueone");
        JSONArray valueTwoArray = jArray.getJsonArray("valuetwo");

        for(int i=0; i < valueOneArray.length(); ++i){
            JsonObject valueOneObject = valueOneArray.getJsonObject(i);
            spinnerValueOne.add(valueOneObject.getString("title"));
        }

        for(int i=0; i < valueTwoArray.length(); ++i){
            JsonObject valueTwoObject = valueTwoArray.getJsonObject(i);
            spinnerValueTwo.add(valueTwoObject.getString("title"));
        }

        ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(this,
                android.R.layout.simple_spinner_item, spinnerValueOne);


        ArrayAdapter<String> adapter2 = new ArrayAdapter<String>(this,
                android.R.layout.simple_spinner_item, spinnerValueTwo);

        spinner1.setAdapter(adapter1);
        spinner2.setAdapter(adapter2);
    }
}
