将库更新到 Gradle 文件后，我在尝试通过电话号码进行身份验证后遇到此错误。

我搜索了一个解决方案，但同样的问题

我将这些用于 Firebase 的库放入 Gradle

// Firebase
implementation platform('com.google.firebase:firebase-bom:26.0.0')
//Firebase Authentication
implementation 'com.google.firebase:firebase-auth' …

我在 Android 中像这样调用 MaterialDatePicker：

MaterialDatePicker.Builder<Pair<Long, Long>> builder = MaterialDatePicker.Builder.dateRangePicker();

CalendarConstraints.Builder constraintsBuilder = new CalendarConstraints.Builder();
builder.setCalendarConstraints(constraintsBuilder.build());

int dialogTheme = resolveOrThrow(getContext(), R.attr.materialCalendarTheme);
builder.setTheme(dialogTheme);

MaterialDatePicker<?> picker = builder.build();

picker.show(getFragmentManager(), picker.toString());

图书馆是：

dependencies {
    implementation 'com.google.android.material:material:1.2.0-alpha01'
}

如何获取此日历的选定日期？我找不到任何听众喜欢onDateSet或OnDateSetListener

我有这个值转换器，可以将数字转换为画笔颜色。我需要做的是将行更改return Brushes.Red;为return (Brush)FindResource("PrimaryHueMidBrush");，这样我就可以返回主题的颜色。问题是我不知道如何声明(Brush)FindResource("PrimaryHueMidBrush");. 欢迎任何帮助。先感谢您。

public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
    double.TryParse(value.ToString(), out double val);

    if (val == 1)
    {
        return Brushes.Red;
    }
    else if(val == 0.5)
    {
        return Brushes.MediumVioletRed;
    }
    else if(val==0)
    {
        return Brushes.Transparent;
    }
    else
    {
        return Brushes.Transparent;
    }
}

public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
    throw new NotImplementedException();
}

我有一个具有这种结构的 Firebase 数据库

{
  "foo" : {
    "data" : {
      "2019-12-01" : [ {
        "item1" : 8,
        "item2" : 16,
        "name" : "user1"
      }, {
        "item1" : 9,
        "item2" : 18,
        "name" : "user2"
      } ],
      "2019-12-02" : [ {
        "item1" : 2,
        "item2" : 26,
        "name" : "user1"
      }, {
        "item1" : 6,
        "item2" : 6,
        "name" : "user2"
      } ]
    }
  }
}

我正在recyclerviewer以一种非常简单的方式填写主要活动：

public class MainActivity extends AppCompatActivity {

    RecyclerView recyclerView;

    private RecyclerView.LayoutManager layoutManager;
    private …

我在 C# 中有这个任务，我想使用 dapper 在 MySql 中调用存储过程。

public async Task<List<StatItemListViewModel>> GetTable()
    {
        using (MySqlConnection connection = new MySqlConnection(Helper.CnnVal("SampleDB")))
        {
            var results =await connection.QueryAsync<List<StatItemListViewModel>>("Call MainResult_Statistic(@sDate, @eDate)", new { sDate = "2018-11-01", eDate = "2018-11-30" });

            return results.FirstOrDefault();
        }            
    }

问题是它不返回任何东西。

有人能帮助我吗？
