用第二个 AsyncTask 填充第二个微调器后，JSON id 位置发生了变化

问题描述 投票：0回答：1

我遇到一个问题，我真的很困惑，做了很多调试，但仍然无法解决问题。

当使用第二个异步任务生成第二个微调器时，

id_kecamatan = categoriesList.get(position).getId();
值发生了变化，这不应该发生，但是如果我不执行
public void onItemSelected
中找到的代码，则ID位置的值不会改变，这是假设的如果我不输入此代码，我将无法填充第二个微调器，因为第二个微调器基于第一个微调器值。此问题导致 onSelectedItem 多次循环。请帮忙。谢谢。

如果我把这段代码放在下面，

categoriesList.get(position).getId();
就会改变。

    if (cekspin != cekstatusspin1){
                    spinnerFood2.setEnabled(true);
                    id_kecamatan = categoriesList.get(position).getId();
                    Log.d("MASUK KE 2: ", "> " + id_kecamatan);
                    cekstatusspin1 = cekspin;
    
//run the second asynctask for second spinner
                    runMultipleAsyncTask2();
                    }

完整代码如下：

public class MainActivity extends Activity implements OnItemSelectedListener {

    private Spinner spinnerFood;
    private Spinner spinnerFood2;
    // array list for spinner adapter
    private ArrayList<Category> categoriesList;
    private ArrayList<Category> categoriesList2;

    private String URL2 = URL_CATEGORIES2;
    TextView texji;
    String cekstatusspin1,cekspin,cekspin2,b= null;
    String nilai = "ada";
    ArrayAdapter<String> spinnerAdapter2;
    @Override

        spinnerFood2 = (Spinner) findViewById(R.id.spinner2);
        spinnerFood2.setEnabled(false);
        categoriesList = new ArrayList<Category>();
        categoriesList2 = new ArrayList<Category>();

        texji = (TextView)findViewById(R.id.text);
        // spinner item select listener
        spinnerFood.setOnItemSelectedListener(this);
        spinnerFood2.setOnItemSelectedListener(this);

哦，我找到了解决方案，问题就在

onItemSelected
我只需添加这个即可解决问题！

Spinner spinner = (Spinner) parent;
     if(spinner.getId() == R.id.spinner1)
     {
       //do this                    
     }
     else if(spinner.getId() == R.id.spinner2)
     {
       //do this
     }
