私は本当に混乱していて、非常に多くのデバッグを行っていますが、まだ問題を解決できないという問題があります。2番目のスピンナーに2番目のAsyncTaskを設定した後にJSON IDの位置が変更されました
id_kecamatan = categoriesList.get(position).getId(); 2番目のスピンナーが2番目のAsynctaskで生成されたときに値が変更されましたが、これは発生しないと思われますが、public void onItemSelectedにあるコードが実行されない場合、ID位置の値は変更されません2番目のスピナーは最初のスピナー値に基づいているため、このコードを挿入しないと2番目のスピナーを挿入できません。この問題は、複数のループonSelectedItemを引き起こします。助けてください。ありがとう。
このコードを下に置くと、categoriesList.get(position).getId();が変更されます。
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();
}
はここで完全なコード：
public class MainActivity extends Activity implements OnItemSelectedListener {
private Spinner spinnerFood;
private Spinner spinnerFood2;
// array list for spinner adapter
