在本地存储的imageview中显示图像

问题描述：

我正在开发一个xamarin android应用程序，我已经实现了一个listview。所以我需要将该图像显示到列表视图中，以便如何使用路径在imageview中显示图像。在本地存储的imageview中显示图像

我没有得到如何从xamarin.android

这里我CustomAdaptor文件路径显示图像

internal class MyCustomListAdapter : BaseAdapter 
{ 
    private List<AlbumTable> albm; 
    private LayoutInflater mInflater; 
    Context c; 
    Dialog dialog; 
    public MyCustomListAdapter(Context c,List<AlbumTable> albm) 
    { 
     this.albm = albm; 
     this.c = c; 
     mInflater = (LayoutInflater)c.GetSystemService(Context.LayoutInflaterService); 

    } 

    public override int Count 
    { 

     get 
     { 
      return albm.Count(); 
     } 
    } 

    public override Java.Lang.Object GetItem(int position) 
    { 
     return null; 
    } 

    public override long GetItemId(int position) 
    { 
     return long.Parse(albm[position].Id); 
    } 

    public override View GetView(int position, View view, ViewGroup parent) 
    { 
     Button btnDelete; 

     ViewHolder1 holder = null; 
     if (view == null) 
     { 
      view = mInflater.Inflate(Resource.Layout.inflate_album, null); 
      holder = new ViewHolder1(); 
      holder.coverp = view.FindViewById<ImageView>(Resource.Id.sliderviewpager); 
      btnDelete = view.FindViewById<Button>(Resource.Id.share_album); 
      btnDelete.Focusable = false; 
      btnDelete.FocusableInTouchMode = false; 
      btnDelete.Clickable = true; 
      btnDelete.Click += (object sender, EventArgs e) => 
      { 

       Android.App.AlertDialog.Builder alert = new Android.App.AlertDialog.Builder(c); 
       alert.SetTitle("Delete Album"); 
       alert.SetMessage("Are you really wnt to delete the Album"); 
       alert.SetCancelable(false); 
       alert.SetPositiveButton("Yes", delegate { 
        DatabaseHelper db = new DatabaseHelper(); 
        bool aa=db.DeleteFromTable(albm[position]); 

        if (aa) 
        { 
         Toast.MakeText(c, "Album Deleted Successfully", ToastLength.Short).Show(); 
        } 
       }); 
       alert.SetNegativeButton("No", delegate { 
        if (dialog.IsShowing) 
         dialog.Dismiss(); 
       }); 
       dialog = alert.Create(); 
       dialog.Show(); 

      }; 
     } 
     else 
     { 
      btnDelete = view.FindViewById<Button>(Resource.Id.share_album); 
      holder = view.Tag as ViewHolder1; 
      btnDelete.Tag = position; 

     } 

     return view; 
    }

和我的getter setter方法如下所示

class AlbumTable 
{ 

    [PrimaryKey] 
    public string Id { get; set; } 

    public string ZipFillPath { get; set; } 

    public string CoverPhotoPath { get; set; } 

    public string AlbumKey { get; set; } 

    public string NoOfPages { get; set; } 

    public string Email { get; set; } 

    public string LastName { get; set; } 

    public string FirstName { get; set; } 

    public string City { get; set; } 

    public string Address1 { get; set; } 

    public string ZipPostalCode { get; set; } 

    public string PhoneNumber { get; set; }

}

如何使用路径在imageview中显示图像。

答

如何使用路径在imageview中显示图像。

有一些第三方库可以很好地实现此功能，如Picasso或Glide。

对于毕加索，有官方文档显示如何在Xamarin.Android项目中使用它。Binding a .JAR。

然后你就可以像这样的例子代码：

Picasso.With(this).Load(imageUrl).Into(imageView);
