Android数据库日期类型setViewBinder

Question

我想知道如何使用setViewBinder。当我尝试这个时，所有列都会改变相同的日期，即使它有数据。如何编辑每个列，这是相关日期，而不是每列？ 我认为我必须修改setViewBinder部分。 你能帮帮我吗？

protected void onActivityResult(int requestCode, int resultCode,Intent intent) 
{
   super.onActivityResult(requestCode, resultCode, intent);
   fillData();
}

private void fillData()
{
   cursor = dbHelper.fetchAllItems();
   startManagingCursor(cursor);
   String[] from = new String[] {FridgeDbAdapter.KEY_NAME,    
                                FridgeDbAdapter.KEY_EXPIRED_DATE};
   int [] to = new int[] {R.id.fridge_name_txt, R.id.fridge_expired_txt};
   SimpleCursorAdapter data_row = new SimpleCursorAdapter(this, R.layout.fridge_row,
   cursor, from, to);

   //It makes crash the list which is making all same date..
   data_row.setViewBinder(new SimpleCursorAdapter.ViewBinder() {

   //How can I bind the data with only specific date column?
   public boolean setViewValue(View view, Cursor cursor, int column) 
   {
      TextView tv = (TextView) view;
      String date = cursor.getString(cursor.getColumnIndex("expired_date"));
  SimpleDateFormat df = new SimpleDateFormat("dd-MM-yyyy");
  Calendar cal = Calendar.getInstance();
  date = df.format(cal.getTimeInMillis());
  tv.setText(date);
  return true;
  }
   });*/
   setListAdapter(data_row);
}

*****我编辑了setViewBinder ..但是，它显示的是每列的日期，而不是特定的列。日期显示01-01-1970，而不是像12/11/2011 .. 我该怎么办？**

data_row.setViewBinder(new SimpleCursorAdapter.ViewBinder() {

public boolean setViewValue(View view, Cursor cursor, int column) 
{
if(column>=0)
   {
TextView tv = (TextView) view;
    long date=cursor.getLong(cursor.getColumnIndex("expired_date"));
Calendar cal = Calendar.getInstance();
cal.clear();
    cal.setTimeInMillis(date);
    String date_format = String.format("%1$td-%1$tm-%1$tY", cal);
tv.setText(date_format);
return true;
    }
  return false;
  }

}）;

Answer 1

它是由此代码引起的

String date = cursor.getString(cursor.getColumnIndex("expired_date"));

你应该做这样的事

String date = cursor.getString(column);

接下来你必须检查列== cursor.getColumnIndex（“expired_date”） 并且只有在其他情况下你才能使用日期字符串

中的数据设置电视时才进行格式化

Answer 2

您的代码中的错误是您从未解析从数据库获取的日期。

尝试

    public boolean setViewValue(View view, Cursor cursor, int column) 
   {
      TextView tv = (TextView) view;
      String date = cursor.getString(cursor.getColumnIndex("expired_date"));
      tv.setText(date);
      return true;
  }

如果来自数据库的日期没有格式化您希望如何格式化，那么：

public boolean setViewValue(View view, Cursor cursor, int column) 
   {
      TextView tv = (TextView) view;
      String dbDate = cursor.getString(cursor.getColumnIndex("expired_date"));
      SimpleDateFormat dbDateFormat = new SimpleDateFormat("****db date format***");
      SimpleDateFormat outputFormat = new SimpleDateFormat("****output format***");
      Date date = dbDateFormat.parse(dbDate);
      tv.setText(outputFormat.format(date));
      return true;
  }
