如何在AlertDialog框中添加兩個編輯文本字段或視圖？

Question

我想在警報對話框中添加兩個編輯文本字段。就像解決方案聽起來一樣簡單，我還沒有能夠收集到一個工作。我無法同時設置兩個（編輯文本）視圖。

如果您想查看任何進一步的代碼，請留下您的意見。

   alertDialog.setTitle("Values"); 
       final EditText quantity = new EditText(SecondScan.this); 
       final EditText lot = new EditText(SecondScan.this); 

       quantity.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL); 
       lot.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL); 

       Project=arr[0].toString(); 
       Item=arr[1].toString(); 


       alertDialog.setMessage("Employee No. : " + (Login.user).trim()+ 
         "\nWarehouse  : " + (FirstScan.Warehouse).trim()+ 
         "\nLocation   : " + (FirstScan.Location).trim()+ 
         "\nProject    : " + Project.trim() + 
         "\nItem     : " + Item.trim() + 
         "\nLot      : " + Lot.trim()+ 
         "\n\nQuantity :"); 
       alertDialog.setView(quantity); 
        alertDialog.setView(lot); 
// the bit of code that doesn't seem to be working. 


       alertDialog.setCancelable(false); 
       alertDialog.setPositiveButton("Update", new DialogInterface.OnClickListener() { 

        public void onClick(DialogInterface dialog, int id) { 
         //ACTION 
        } 
       }); 

       AlertDialog alert = alertDialog.create(); 
       alert.show(); 

我想很多，第二個的量後，而只是其中的一種，似乎當我在這兩種意見儘量推到被加工後發生的第一個編輯文本。

UPDATE：事實證明其實也有不單獨添加多個視圖一個警告對話框，而不必爲它創建一個佈局的方法。

在android中查看Creating a Custom Layout。

編輯

alertDialog.setTitle("Values"); 
final EditText quantity = new EditText(SecondScan.this); 
final EditText lot = new EditText(SecondScan.this); 

quantity.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL); 
lot.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL); 

Project=arr[0].toString(); 
Item=arr[1].toString(); 

LinearLayout ll=new LinearLayout(this); 
ll.setOrientation(LinearLayout.VERTICAL); 
ll.addView(quantity); 
ll.addView(lot); 
alertDialog.setView(ll); 

alertDialog.setCancelable(false); 
alertDialog.setPositiveButton("Update", new DialogInterface.OnClickListener() { 
    public void onClick(DialogInterface dialog, int id) { 
     //ACTION 
    } 
}); 

AlertDialog alert = alertDialog.create(); 
alert.show();

您應該創建一個垂直LinearLayout，您可以在其上添加EditTexts。然後使用alertDialog.setView（）和LinearLayout。

你爲什麼不做出它完全自定義佈局？

這是用於顯示分類列表並讓用戶選擇一個的自定義彈出窗口。

public class CategoryPickerFragment extends DialogFragment implements OnItemClickListener{ 
private CategoryReceiver receiver; 
@Override 
public Dialog onCreateDialog(Bundle savedInstanceState) { 
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); 
    // Get the layout inflater 
    LayoutInflater inflater = getActivity().getLayoutInflater(); 

    // Inflate and set the layout for the dialog 
    // Pass null as the parent view because its going in the dialog layout 
    View view = inflater.inflate(R.layout.category_picker_fragment, null); 

    builder.setView(view); 
    AlertDialog ad = builder.create(); 

    CategoryList categoryList = (CategoryList) view.findViewById(R.id.clCategories); 
    categoryList.setOnItemClickListener(this); 

    return ad; 
} 
public void setCategoryReceiver(CategoryReceiver receiver){ 
    this.receiver = receiver; 
} 

@Override 
public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 
    Category category = ((CategoryListChild)view).getCategory(); 
    receiver.setCategory(category); 
    this.dismiss(); 
} 

請注意，我伸出DialogFragment，覆蓋OnCreateDialog一個alertDialog與自定義佈局，然後將其展示給用戶。

我用的LinearLayout一個登錄彈出：

public final String POPUP_LOGIN_TITLE="Sign In"; 
public final String POPUP_LOGIN_TEXT="Please fill in your credentials"; 
public final String EMAIL_HINT="--Email--"; 
public final String PASSWORD_HINT="--Password--"; 

AlertDialog.Builder alert = new AlertDialog.Builder(this); 

     alert.setTitle(POPUP_LOGIN_TITLE); 
     alert.setMessage(POPUP_LOGIN_TEXT); 

     // Set an EditText view to get user input 
     final EditText email = new EditText(this); 
     email.setHint(EMAIL_HINT); 
     final EditText password = new EditText(this); 
     password.setHint(PASSWORD_HINT); 
     LinearLayout layout = new LinearLayout(getApplicationContext()); 
     layout.setOrientation(LinearLayout.VERTICAL); 
     layout.addView(email); 
     layout.addView(password); 
     alert.setView(layout); 

     alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int whichButton) { 

      // Do something with value! 
      } 
     }); 

     alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { 
      public void onClick(DialogInterface dialog, int whichButton) { 
      // Canceled. 
      } 
     }); 

     alert.show();
