将选定的图像从SD卡上传到php服务器

Question

在我的android应用程序中，我能够捕捉图像并存储在SD卡中。我有一个选择按钮和复选框来选择图片。但我不知道如何上传选定的图像到一个PHP服务器，通过我的网站显示。代码发布如下，请告诉如何上传这些选定的图像。谢谢

imageAdapter = new ImageAdapter(); 
imageAdapter.initialize(); 
imagegrid = (GridView) findViewById(R.id.PhoneImageGrid); 
imagegrid.setAdapter(imageAdapter); 
final Button selectBtn = (Button) findViewById(R.id.selectBtn); 
selectBtn.setOnClickListener(new OnClickListener() { 
public void onClick(View v) { 
    final int len = imageAdapter.images.size(); 
int cnt = 0; 
    String selectImages = ""; 
       for (int i = 0; i < len; i++) { 
        if (imageAdapter.images.get(i).selection) { 
         cnt++; 
         selectImages = selectImages 
           + imageAdapter.images.get(i).id + ","; 
        } 
       } 
       if (cnt == 0) { 
        Toast.makeText(getApplicationContext(), 
          "Please select at least one image", 
          Toast.LENGTH_LONG).show(); 
       } else { 
        selectImages = selectImages.substring(0,selectImages.lastIndexOf(",")); 
        Intent intent = new Intent(MainActivity.this, 
          UploadQueue.class); 
        intent.putExtra("Ids", selectImages); 

        startActivityForResult(intent, UPLOAD_IMAGES); 
       } 

Answer 1

1）服务器

2）图像转换为机器人

3 Base64编码字符串）发送字符串到web服务对ksoap2

4创建一个Web服务）将字符串转换回web服务中的图像（如果不需要，则不需要将其转换为图像文件）

5）将其保存在服务器的硬盘上

编辑：

public static Bitmap base64ToBitmap(String strBase64) throws IOException { 
     byte[] bitmapdata = Base64.decode(strBase64); 
     Bitmap bitmap = BitmapFactory.decodeByteArray(bitmapdata, 0, 
       bitmapdata.length); 
     return bitmap; 
    } 

public static String bitmapToBase64(Bitmap bitmap) { 
     byte[] bitmapdata = bitmapToByteArray(bitmap); 
     return Base64.encodeBytes(bitmapdata); 
    } 

public static byte[] bitmapToByteArray(Bitmap bitmap) { 
    ByteArrayOutputStream bos = new ByteArrayOutputStream(); 
    bitmap.compress(CompressFormat.PNG, 0 /* ignored for PNG */, bos); 
    byte[] bitmapdata = bos.toByteArray(); 
    return bitmapdata; 
} 

或

public static byte[] fileToByteArray(String path) throws IOException { 
     File imagefile = new File(path); 
     byte[] data = new byte[(int) imagefile.length()]; 
     FileInputStream fis = new FileInputStream(imagefile); 
     fis.read(data); 
     fis.close(); 
     return data; 
    } 


public static String fileToBase64(String path) throws IOException { 
     byte[] bytes = fileToByteArray(path); 
     Base64.encodeBytes(bytes); 
    } 


public static void base64ToFile(String path, String strBase64) 
      throws IOException { 
     byte[] bytes = Base64.decode(strBase64); 
     byteArrayTofile(path, bytes); 
    } 

public static void byteArrayTofile(String path, byte[] bytes) 
      throws IOException { 
     File imagefile = new File(path); 
     File dir = new File(imagefile.getParent()); 
     if (!dir.exists()) { 
      dir.mkdirs(); 
     } 
     FileOutputStream fos = new FileOutputStream(imagefile); 
     fos.write(bytes); 
     fos.close(); 
    }
