自定義對話框中的按鈕將不會響應

我正在嘗試爲我的應用程序的設置創建自定義對話框，問題是自定義按鈕，編輯文本框不響應用戶活動。我希望有人能幫幫忙。這裏是我的代碼：自定義對話框中的按鈕將不會響應

public class SettingsDialog extends DialogFragment { 
private EditText editText; 
private Spinner ipSpinner; 
private MainActivity mainActivity; 
private Settings settings; 
private int selectedIP; 

@Override 
public Dialog onCreateDialog(Bundle savedInstanceState) { 
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); 
    LayoutInflater inflater = getActivity().getLayoutInflater(); 
    final View dialogView = inflater.inflate(R.layout.dialog_settings, null); 
    mainActivity = (MainActivity) getActivity(); 
    settings = mainActivity.getSettings(); 
    selectedIP = settings.getSelectedIP(); 
    editText = (EditText) dialogView.findViewById(R.id.edit_text_ip); 
    ipSpinner = (Spinner) dialogView.findViewById(R.id.spinner_ip); 
    ImageButton imageButton = (ImageButton) dialogView.findViewById(R.id.image_button_save_ip); 
    imageButton.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      String IP = editText.getText().toString(); 
      settings.setIP(selectedIP, IP); 
      settings.settingsSave(); 
      mainActivity.showToast("IP at " + Integer.toString(selectedIP) + " with value" + IP); 
     } 
    }); 
    ipSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() { 
     @Override 
     public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) { 
      selectedIP = position; 
      editText.setText(settings.getIP(selectedIP)); 
      mainActivity.showToast(Integer.toString(position)); 
      settings.settingsSave(); 
     } 

     @Override 
     public void onNothingSelected(AdapterView<?> parentView) { 
      return; 
     } 

    }); 
    builder.setView(inflater.inflate(R.layout.dialog_settings, null)) 

      .setPositiveButton("Save", new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialog, int id) { 
        String IP = editText.getText().toString(); 
        settings.setIP(selectedIP, IP); 
        settings.settingsSave(); 
        mainActivity.showToast("IP at " + Integer.toString(selectedIP) + " with value" + IP); 
       } 
      }) 
      .setNegativeButton("Cancel", new DialogInterface.OnClickListener() { 
       public void onClick(DialogInterface dialog, int id) { 
        SettingsDialog.this.getDialog().cancel(); 
       } 
      }); 
    return builder.create(); 
}

}

和我的對話XML：

您正在膨脹dialogView，然後你爲dialogView中的視圖設置監聽器，但是當你使用等對話框構建器的視圖，則會誇大新視圖。

這是錯誤的。

builder.setView(inflater.inflate(R.layout.dialog_settings, null))

這是正確的

builder.setView(dialogView)
