如何在片段 Xamarin Android Native 中使用 SQLite 在 Recycler View Card View 中顯示數據

[英]How To Show Data in Recycler View Card View with SQLite in fragment Xamarin Android Native

問題描述

我是 Xamarin 和 Android 的新手。我想將我的數據從 SQLITE 顯示到片段中帶有 xamarin.android 的回收站視圖 cardview。 我在那里找到了一個例子https://www.c-sharpcorner.com/article/xamarin.android-recyclerv/從字面上看，我想像鏈接一樣實現，但它不使用 SQLite 而不是片段。 我想在回收站視圖卡片視圖中顯示照片。 我已經在 inte.net 中搜索過，但我仍然沒有得到我想要的。 我試過了，但還是卡住了。 讓我在 main.xml 中顯示我的代碼

<android.support.v7.widget.RecyclerView 
    android:id="@+id/recyclerView" 
    android:scrollbars="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"/>

在我的美食卡視圖中

我知道這很簡單，我是菜鳥。 你願意幫助我嗎？ 我真的很感激！ 預先感謝

我寫了一個關於你的需求的演示，這是運行截圖。

在此處輸入圖像描述

我使用Fragments （包含RecycleView ）和Viewpager ， sqlite來實現它。

首先，如果你使用 ImageView 來顯示圖像。 你應該知道如何存儲圖像。 使用 Base64String 或 imagePath，我使用 Base64String 將字符串存儲到 Sqlite 數據庫中。 這是我的 Util class。它可以將 Bitmap 轉換為字符串並將字符串轉換為 bitmap。

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;

using Android.App;
using Android.Content;
using Android.Graphics;
using Android.OS;
using Android.Runtime;
using Android.Util;
using Android.Views;
using Android.Widget;

namespace BottomNavigation
{
    public class MyUtils
    {
        public static string ConvertBitMapToString(Bitmap bitmap)
        {

            byte[] bitmapData;
            using (MemoryStream stream = new MemoryStream())
            {
                bitmap.Compress(Android.Graphics.Bitmap.CompressFormat.Jpeg, 50, stream);
                bitmapData = stream.ToArray();
            }

            string ImageBase64 = Convert.ToBase64String(bitmapData);

            return ImageBase64;
        }

        public static Bitmap ConvertStringToBitmap(string mystr)
        {
            byte[] decodedString = Base64.Decode(mystr, Base64Flags.Default);
            Bitmap decodedByte = BitmapFactory.DecodeByteArray(decodedString, 0, decodedString.Length);

            return decodedByte;
        }
    }
}

在 Install 標簽中，我初始化了 sqlite DB，因為這個標簽有一個第一個顯示Fragment 。

  public static void DoSomeDataAccess()
        {
            Console.WriteLine("Creating database, if it doesn't already exist");
            string dbPath = Path.Combine(
                 System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal),
                 "ormdemo.db3");
            db = new SQLiteConnection(dbPath);
            db.CreateTable<MyModel>();


            if (db.Table<MyModel>().Count() == 0)
            {
                // only insert the data if it doesn't already exist
                var newStock = new MyModel();
                newStock.ImageBase64String =

            }
            Console.WriteLine("Reading data");
          //  var table = db.Table<MyModel>();

        }

我創建了一個名為 MyModel 的MyModel 。 您可以添加您需要的其他屬性。

 [Table("Items")]
    public class MyModel
    {
        [PrimaryKey, AutoIncrement, Column("_id")]
        public int Id { get; set; }

        public string ImageBase64String { get; set; }
        public string Name { get; set; }
        public string Descirption { get; set; }
    }

NewsFragment.cs包含RecycleView 。 MyAdapter.cs是一個RecyclerView.Adapter 。

其他代碼你可以參考我的demo，這里是我的demo鏈接。
