android-自定義listview與edittext

我有一個自定義listView與editText在每一行進行價值輸入的用戶。，並且我在列表視圖旁邊有一個按鈕，onclick會將列表中所有行的editText值加起來。android-自定義listview與edittext

任何人都可以給我一些線索的一些線索。

import android.app.Activity; 
import android.app.ListFragment; 
import android.content.PeriodicSync; 
import android.os.Bundle; 

import android.text.InputFilter.LengthFilter; 
import android.util.Log; 

import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.ArrayAdapter; 
import android.widget.Button; 
import android.widget.EditText; 
import android.widget.ListView; 
import android.widget.TextView; 
import android.widget.Toast; 

    public class NRSessionScheduleFragmentOne extends ListFragment { 

     String[] dummyVal = new String[] { "hello", "how", "are", "u", "how", 
       "are", "u", "how", "are" }; 
     ListView parentList; 
     int addVal; 
     EditText period; 

     private NRSessionFragmentHolder parentobj; 

     public void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
     } 

     public View onCreateView(LayoutInflater inflater, ViewGroup container, 
       Bundle savedInstanceState) { 

      View v = inflater.inflate(R.layout.nrtpsessiontopics, container, false); 
      return v; 
     } 

     public void onActivityCreated(Bundle savedInstanceState) { 
      super.onActivityCreated(savedInstanceState); 
      setListAdapter(new MyListAdapter(getActivity())); 
      parentList = (ListView) getActivity().findViewById(android.R.id.list); 
      addVal = valueReturn(dummyVal, period, parentList); 
     } 

     public class MyListAdapter extends ArrayAdapter { 
      Activity contextACT; 

      public MyListAdapter(Activity context) { 
       super(context, R.layout.nrrow_of_list_lesson, dummyVal); 
       this.contextACT = context; 
      } 

      public View getView(final int position, View convertView, 
        ViewGroup parent) { 
       LayoutInflater inflator = contextACT.getLayoutInflater(); 
       final View row = inflator.inflate(R.layout.nrrow_of_list_lesson, 
         null); 
       final TextView name = (TextView) row.findViewById(R.id.lessonname); 
       period = (EditText) row.findViewById(R.id.ssperiodeditText); 
       final Button increase = (Button) row.findViewById(R.id.ssincrease); 
       final Button decrease = (Button) row.findViewById(R.id.ssdecrease); 
       increase.setId(position); 
       decrease.setId((dummyVal.length) + position); 

       final Integer currentQuant = Integer.parseInt(period.getText() 
         .toString()); 

       increase.setOnClickListener(new View.OnClickListener() { 

        public void onClick(View v) { 

         increase.getId(); 
         Log.w("button value", "" + increase.getId()); 
         if (currentQuant != 0) { 
          period.setText(new Integer(currentQuant + 1).toString()); 
         } 

        } 
       }); 

      decrease.setOnClickListener(new View.OnClickListener() { 

       public void onClick(View v) { 
        // TODO Auto-generated method stub 

        Log.w("button value1", " " + decrease.getId()); 
        decrease.getId(); 
        if (currentQuant != 1) { 
         period.setText(new Integer(currentQuant - 1).toString()); 
        } 

       } 
      }); 


      return (row); 

     } 

    } 

    void setParent(NRSessionFragmentHolder parent) { 
     this.parentobj = parent; 
    } 

    public int valueReturn(String[] dummyVal, EditText period2, 
      ListView parentList) { 
     Integer add = 0; 
     for (int i = 0; i <= dummyVal.length; i++) { 
      View temp = null; 
      temp = parentList.getChildAt(i); 
      while (!(temp == null)) { 
       add = Integer.parseInt(period2.getText().toString()); 

      } 
     } 
     return add; 
    } 

}

鏈接到什麼？你的問題是什麼？ – Egor 2011-12-29 08:16:36

它只是我要檢索每個編輯框中存在的所有值 – Vivekanand 2011-12-29 08:21:07

我已添加我的代碼。我正在使用片段方法 – Vivekanand 2011-12-29 08:35:14

你需要你的按鈕的onClickListener()得到的ListView適配器，將其轉換爲一個列表，並總結列表的內容。

嘿我想出了一種方法來做到這一點....它原來是非常簡單的....這裏是代碼....在這裏，我用一個ListView來代替值... 。

parentList=(ListView)findViewByid(R.id.list); 

public int getTvValue() { 
    View view; 
    String[] edVal = new String[parentList.getChildCount()]; 
    int val = 0; 
    for (int i = 0; i < parentList.getCount(); i++) { 
     view = parentList.getChildAt(i); 
     TextView tv = (TextView) view.findViewById(R.id.TVmid); 
     edVal[i] = tv.getText().toString(); 
     val = Integer.parseInt(edVal[i]) + val; 
    } 
    return val; 

}
