我想要一个alertDialog（里面有editText和spinner）来在数据库中添加一些数据。如果用户想要添加一个不在微调器中的值，我在微调器旁边添加了一些“新”按钮。这应该打开一个新的alertDialog，其中包含与新表相关的自定义字段。 一切工作都在我的“新”按钮的onClick（）内部执行show（）方法。 我的代码：
package com.dg
// import ...
public class MainActivity extends Activity
{
// nouvelle classe :
// ajouter dans listeDAO
// ajoiter dans databasehandler
// si champs.size!=2,6,7
// implémenter refresh, liste_i
// header_i, ...
// declarations
public static final int MAX_SIZE_CHAMPS = 7;
public Context context = null;
public List<DAO> listeDAO = null;
public List<Cursor> listeCursor = null;
public AlertDialog alertDialogAjouter, alertDialogSupprimer = null;
public AlertDialog.Builder alertDialogBuilderAjouter, alertDialogBuilderSupprimer = null;
public LinearLayout customHeader, mainLayout = null;
public List<EditText> listeEt = null;
public List<Spinner> listeSp = null;
public List<Button> listeBt = null
public View dialogView = null;
// ...
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
context = this;
// ...
listeTv = new ArrayList<TextView>();
listeEt = new ArrayList<EditText>();
listeSp = new ArrayList<Spinner>();
listeBt = new ArrayList<Button>();
listeCursor = new ArrayList<Cursor>();
LayoutInflater inflater = LayoutInflater.from(context);
dialogView = inflater.inflate(R.layout.dialog, null);
for (int index=0; index < MAX_SIZE_CHAMPS; index++)
{
listeTv.add((TextView)dialogView.findViewById(tabTv[index]));
listeEt.add((EditText)dialogView.findViewById(tabEt[index]));
listeSp.add((Spinner)dialogView.findViewById(tabSp[index]));
listeBt.add((Button)dialogView.findViewById(tabBt[index]));
listeBt.get(index).setOnClickListener(buttonNewListener);
listeCursor.add(null);
}
// ...
alertDialogBuilderAjouter = new AlertDialog.Builder(context);
alertDialogBuilderAjouter.setTitle("ajout");
alertDialogBuilderAjouter.setView(dialogView);
alertDialogBuilderAjouter.setPositiveButton("ajouter", ajouterDialogButton);
alertDialogBuilderAjouter.setNegativeButton("annuler", null);
alertDialogAjouter = alertDialogBuilderAjouter.create();
}
public OnClickListener ajouterListener = new OnClickListener()
{
@Override
public void onClick(View v)
{
DAO ajDAO = listeDAO.get(queueDAO.get(queueDAO.size() - 1));
for (int i = 0; i < ajDAO.getNombreDeChamps(); i++)
{
valeursEntreesListe.add(new String());
}
prepareBox(ajDAO); // juste some opérations on textView, editText etc.
alertDialogAjouter.show();
}
};
public OnClickListener buttonNewListener = new OnClickListener()
{
@Override
public void onClick(View v)
{
for (int i= 0; i<MAX_SIZE_CHAMPS; i++)
{

{
// ...

Toast.makeText(context, "test", Toast.LENGTH_SHORT).show();

adb.setPositiveButton("ajouter", ajouterDialogButton);

ad = adb.create();
DAO ajDAO = listeDAO.get(queueDAO.get(queueDAO.size() - 1));
for (int j = 0; j < ajDAO.getNombreDeChamps(); j++)
{
valeursEntreesListe.add(new String());
}
prepareBox(ajDAO);
finish();
ad.show(); // crash here!
}
}
}
};
public DialogInterface.OnClickListener ajouterDialogButton = new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
DAO ajDAO = null;
if (queueDAO.size() > 0)
{
ajDAO = listeDAO.get(queueDAO.get(queueDAO.size() - 1));
}
if (ajDAO != null)
{
for (int i=0; i < ajDAO.getNombreDeChamps(); i++)
{
if (!ajDAO.isFK(i))
{
valeursEntreesListe.set(i, (listeEt.get(i).getText().toString()));
}
}
valeursEntreesListe.set(ajDAO.getIndexPK(), "-1");
try
{
ajDAO.ajouter(ajDAO.createEntiteFromList(valeursEntreesListe));
}
catch (Exception e)
{
Toast.makeText(context, "ajout : " + e.toString(), Toast.LENGTH_LONG).show();
}
refresh(ajDAO);
}
else if (ajDAO == null)
{
Toast.makeText(context, "Selectionner d'abord une table", Toast.LENGTH_LONG).show();
}
}
};
}

我在这个网站上搜索但没有找到有用的东西。 我是新来的，所以如果我犯了错误，不要责怪我太多。 你能帮帮我吗？
编辑已经在show（）
之前尝试了dismiss（）答案 0 :(得分：2)
您将dialogView用于两个警报对话框。我认为这是问题所在。
第一个对话框设置dialogView的父级。当您尝试创建第二个对话框时，dialogView已经有父对象。
为第二个对话框创建不同的dialogView。
