这就是我想要做的，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，但我收到了大量警告，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：

XML 剪辑：

<TextView
    android:id="@+id/txtCreatedAt"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_marginLeft="24dp"
    android:layout_toRightOf="@+id/image"
    android:gravity="left"
    android:paddingLeft="20sp"
    android:text="@string/defDate" />

变成：

  private Date parseDate(String date) {
        SimpleDateFormat curFormater = new SimpleDateFormat("yyyy-MM-dd");
        Date dateObj = new Date();

        try {
            dateObj = curFormater.parse(date);
        } catch (java.text.ParseException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return dateObj;
    }

    @Override
    public boolean setViewValue(View view, Cursor cursor, int columnIndex) {

         if (columnIndex == cursor.getColumnIndex(StatusData.KEY_CHARTING_DATE)) {
             SimpleDateFormat format = new SimpleDateFormat("MM/dd/yyyy");
             String date = cursor.getString(columnIndex);
             Date dateObj = parseDate(date);

             String formatedDate = format.format(dateObj);

             TextView tv = (TextView) view;
             tv.setText(formatedDate);
             return true;
         }

您将非法参数传递给dateFormat.format(). 它应该是一个Date对象。有关其他有效参数，请参阅文档。
