Question

尝试从资源中加载Drawable。获得此追溯和崩溃：

protected void GetItemList()
{
    using (SqlCommand cmd = new SqlCommand("select ID, Group from TableGroup order by Group"))
    {
        cmd.CommandType = CommandType.Text;
        cmd.Connection = conn;
        conn.Open();
        cboGroup.DataSource = cmd.ExecuteReader();
        cboGroup.DataTextField = "Group";
        cboGroup.DataValueField = "ID";
        cboGroup.DataBind();
        conn.Close();
    }
}

我试图按照修复加载： Resources$NotFoundException: File res/drawable/abc_ic_ab_back_material.xml

您应该添加setCompatVectorFromResourcesEnabled。

启用后，AppCompat可以截取一些可绘制的通货膨胀框架，它可以实现内部矢量抽象的隐式膨胀 DrawableContainer资源。

public MyOtherDbContext : DbContext
{
     public DbSet<ExtendePerson> ExtendedPersons {get; set;}
     public DbSet<Grade> Grades {get; set;}   
     public DbSet<Hobby> Hobbies {get; set;}

     public override void OnModelCreating(...)
     {
         // every extended person has zero or more Grades
         // every Grade belongs to exactly one Person
         // using foreign key PersonId
         modelBuilder.Entity<ExtendedPerson>()
             .HasMany(extendedPerson => extendedPerson.Grades)
             .WithRequired(grade => grade.Person)
             .HasForeignKey(grade => grade.PersonId);

         // every extended person has zero or more hobbies
         // every hobby belongs to exactly one ExtendedPerson
         // using foreign  key ExtendedPersonId
         modelBuilder.Entity<ExtendedPerson>()
             .HasMany(extendedPerson => extendedPerson.Hobbies)
             .WithRequired(hobby => hobby.ExtendedPerson)
             .HasForeignKey(hobby => hobby.ExtendedPersonId);

         // proper table name for hobbies:
         modelBuilder.Entity<Hobby>().ToTable("Hobbies");
     }
}

<强> FYI

@Override
protected void onCreate(Bundle savedInstanceState) {
    AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_name);

当找不到请求的资源时，资源API会抛出此异常。查看您当地的 Resources$NotFoundException:File res/drawable-v22/ic_group_tip_1.xml 部分。
