这是我正在尝试做的事情，我有一个viewbinder，我想在这里重新格式化日期并设置文本。我不知道我做错了什么，但我收到了很多警告，它只是锁定了。这是代码：
private class CustomViewBinder implements ViewBinder {
@Override
public boolean setViewValue(View view, Cursor cursor, int columnIndex) {
if (columnIndex == cursor.getColumnIndex(StatusData.KEY_CHARTING_DATE)) {
String date = cursor.getString(columnIndex);
DateFormat dateFormat = android.text.format.DateFormat.getDateFormat(getActivity());
String formatedDate = dateFormat.format(date);
TextView tv = (TextView) view;
tv.setText(formatedDate);
return true;
}
}
警告：
