Android 如何从gridview中的edittext获取值

我在我的项目中使用了网格视图

我的活动布局文件

<GridView
    android:id="@+id/gridView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:gravity="start"
    android:numColumns="1"
    android:stretchMode="spacingWidth"
    android:layout_below="@+id/spinner1"
    android:layout_marginLeft="20dip"
    android:layout_marginRight="10dip"
    android:layout_marginTop="20dip"
    android:visibility="visible"    >
    </GridView>

现在我的问题是 单击“修改”按钮时，我想用新值更新数据库 我尝试使用.gettext（）从编辑文本中获取值。 但它只从first edittext返回值

我是如何从其他EditText获得值的，以及行id

---

所以我用相同设计的新价格更新数据库。

为什么要使用GridView来完成如此简单的工作？ 如果使用ListView，则效果更好，而且填充列表和从其他EditText获取值会更容易

我可以给你一个想法。。。请看下面的代码我在这里做什么：

public class RecordExpenseAdapter extends ArrayAdapter<HashMap<String, String>>
    {

        Intent intent;
        Context context;
        int layoutResourceId;

        public RecordExpenseAdapter(Context context, int layoutResourceId,ArrayList<HashMap<String, String>> RecordList) 
        {
            super(context, layoutResourceId, RecordList);
            this.layoutResourceId = layoutResourceId;

在上面的代码中，我实现了ImageView扫描收据上的单击侦听器。每次都是相同的imageview，即每一行都有相同的布局，这意味着所有行都有相同的id，但仍然有

public void fillgrid(int categoryid,String car){
gridView = (GridView) findViewById(R.id.gridView);

    db.openDataBase();
Cursor c = db.getprice(categoryid); 
startManagingCursor(c);
String[] fromColumns = {"_id",DatabaseClass2.colPrice};
int[] toViews = {R.id.cplabel, R.id.cpprice};
SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, 
        R.layout.grid_change_prices, c, fromColumns, toViews);
        //c.moveToNext();
gridView.setAdapter(adapter); }
