JSON id位置在填充第二个微调器后用第二个AsyncTask改变

2017-05-29 21 views

我有一个问题，我很困惑，做了这么多的调试，但仍然无法解决问题。JSON id位置在填充第二个微调器后用第二个AsyncTask改变

id_kecamatan = categoriesList.get(position).getId();当用第二个Asynctask生成的第二个微调器值不变，但如果我没有执行代码，在public void onItemSelected中发现ID位置的值没有改变，这是假设发生的，如果我没有把这个代码，我不能填充第二个微调，因为第二个微调是基于第一个微调值。此问题导致多个循环onSelectedItem。请帮忙。谢谢。

如果我把这段代码放在下面，categoriesList.get(position).getId();就改变了。

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(); 
        }

这里的完整代码：

public class MainActivity extends Activity implements OnItemSelectedListener { 

    private Spinner spinnerFood; 
    private Spinner spinnerFood2; 
    // array list for spinner adapter

哦，我找到一个解决办法，问题是onItemSelected我只添加这一点，问题就解决了！

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