如何將圖像從sqlite路徑上傳到mysql服務器？

現在我只能上傳文本到MySQL服務器。如何將圖像從sqlite路徑上傳到mysql服務器？

DBcontrooler.java // My SQLite。

public String composeJSONfromSQLite(){ 
    ArrayList<HashMap<String, String>> wordList; 
    wordList = new ArrayList<HashMap<String, String>>(); 
    String selectQuery = "SELECT * FROM home where udpateStatus = '"+"no"+"'"; 
    SQLiteDatabase database = this.getWritableDatabase(); 
    Cursor cursor = database.rawQuery(selectQuery, null); 
    if (cursor.moveToFirst()) { 
     do { 
      HashMap<String, String> map = new HashMap<String, String>(); 
      map.put("idhome", cursor.getString(0)); 
      map.put("mprefix", cursor.getString(1)); 
      map.put("name", cursor.getString(2)); 
      map.put("address", cursor.getString(3)); 
      map.put("district", cursor.getString(4)); 
      map.put("amphoe", cursor.getString(5)); 
      map.put("mprovince", cursor.getString(6)); 
      map.put("community", cursor.getString(7)); 
      map.put("lat", cursor.getString(8)); 
      map.put("longt", cursor.getString(9)); 
      map.put("user", cursor.getString(10)); 
      map.put("cb1", cursor.getString(11)); 
      map.put("cb2", cursor.getString(12)); 
      map.put("cb3", cursor.getString(13)); 
      map.put("cb4", cursor.getString(14)); 
      map.put("cb5", cursor.getString(15));

      map.put("cb11", cursor.getString(21)); 
      map.put("cb12", cursor.getString(22)); 
      map.put("cb13", cursor.getString(23)); 
      map.put("cb14", cursor.getString(24)); 
      map.put("cb15", cursor.getString(25)); 
      map.put("cb16", cursor.getString(26)); 
      map.put("cb17", cursor.getString(27)); 
      map.put("cb18", cursor.getString(28)); 
      map.put("cb19", cursor.getString(29)); 
      map.put("cb20", cursor.getString(30));

      map.put("cb25", cursor.getString(35)); 
      map.put("cb26", cursor.getString(36)); 
      map.put("cb27", cursor.getString(37)); 
      map.put("cb28", cursor.getString(38)); 
      map.put("cb29", cursor.getString(39));

      map.put("cb33", cursor.getString(43)); 
      map.put("cb34", cursor.getString(44)); 
      map.put("sug", cursor.getString(45)); 
      map.put("img1", cursor.getString(46));//imagepath 
      map.put("img2", cursor.getString(47));//imagepath 
      map.put("img3", cursor.getString(48));//imagepath 
      map.put("img4", cursor.getStrin(49)); //imagepath 
      wordList.add(map); 
     } while (cursor.moveToNext()); 
    } 
    database.close(); 
    Gson gson = new GsonBuilder().create(); 
    //Use GSON to serialize Array List to JSON 
    return gson.toJson(wordList); 
}

這：http://stackoverflow.com/questions/25300899/how-to-upload-images-from-android-sqlite-to-local-server-folder-using-json – javadaskari

首先，你應該將圖像保存到一個變量：

File imgFile = new File("/sdcard/Images/test_image.jpg"); 

if(imgFile.exists()){ 

    Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath()); 

    ImageView myImage = (ImageView) findViewById(R.id.imageviewTest); 

    myImage.setImageBitmap(myBitmap); 

}

，包括此權限清單文件：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

然後根據此視頻上傳它： https://www.youtube.com/watch?v=4LCnoVqQ6N4
