如何将图像从 sqlite 路径上传到 mysql 服务器？

Question

现在我只能将文本上传到 MySQL 服务器。

DBcontroler.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("cb17", cursor.getString(27));
            map.put("cb18", cursor.getString(28));
            map.put("cb19", cursor.getString(29));
            map.put("cb20", cursor.getString(30));
            map.put("cb21", cursor.getString(31));

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

            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);
}

Answer 1

首先，您应该将图像保存到变量中：

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);

}

并在清单文件中包含此权限：

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