我试图将包含图片的路径数组上传到我的网络服务,但是我有问题,当我尝试通过post man上传数组时它的工作,但是当我尝试使用android时它&#39 ; s只上传一张图片。
所以这段代码在我选择之后预览图像:
Bundle b;
b = getIntent().getExtras();
public ArrayList<String> map = new ArrayList<String>();
if (b != null) {
ArrayList<String> ImgData = b.getStringArrayList("IMAGE");
for (int i = 0; i < ImgData.size(); i++) {
map.add(ImgData.get(i).toString());
}
}
调试添加到map
的图像后很好。
这是我的完整AsyncTask
:
public class ImageUploadTask extends AsyncTask<String, Void, String> {
String sResponse = null;
@Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
dialog = ProgressDialog.show(ImagesForAds.this, "Uploading",
"Please wait...", true);
dialog.show();
}
@Override
protected String doInBackground(String... params) {
try {
String url = "my url";
int i = Integer.parseInt(params[0]);
Bitmap bitmap = decodeFile(map.get(i));
HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpPost httpPost = new HttpPost(url);
entity = new MultipartEntity();
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bos);
byte[] data = bos.toByteArray();
//entity.addPart("user_id", new StringBody("199"));
//entity.addPart("club_id", new StringBody("10"));
entity.addPart("images[]", new ByteArrayBody(data,
"image/jpeg", params[1]));
Log.i(TAG, "array map: " + map.get(i));
httpPost.setEntity(entity);
HttpResponse response = httpClient.execute(httpPost,
localContext);
sResponse = EntityUtils.getContentCharSet(response.getEntity());
System.out.println("sResponse : " + sResponse);
} catch (Exception e) {
if (dialog.isShowing())
dialog.dismiss();
Log.e(e.getClass().getName(), e.getMessage(), e);
}
return sResponse;
}
@Override
protected void onPostExecute(String sResponse) {
try {
if (dialog.isShowing())
dialog.dismiss();
if (sResponse != null) {
Toast.makeText(getApplicationContext(),
sResponse + " Photo uploaded successfully",
Toast.LENGTH_SHORT).show();
count++;
if (count < map.size()) {
new ImageUploadTask().execute(count + "", "hm" + count
+ ".jpg");
}
}
} catch (Exception e) {
Toast.makeText(getApplicationContext(), e.getMessage(),
Toast.LENGTH_LONG).show();
Log.e(e.getClass().getName(), e.getMessage(), e);
}
}
}
public Bitmap decodeFile(String filePath) {
// Decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeFile(filePath, o);
// The new size we want to scale to
final int REQUIRED_SIZE = 1024;
// Find the correct scale value. It should be the power of 2.
int width_tmp = o.outWidth, height_tmp = o.outHeight;
int scale = 1;
while (true) {
if (width_tmp < REQUIRED_SIZE && height_tmp < REQUIRED_SIZE)
break;
width_tmp /= 5;
height_tmp /= 5;
scale *= 5;
}
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize = scale;
Bitmap bitmap = BitmapFactory.decodeFile(filePath, o2);
return bitmap;
}
调试后我的data
每次都有相同的大小,如果我上传了20张图片,就像上传1张图片一样,尺寸不会改变。
我将AsyncTask()
称为如下:
int count = 0;
new ImageUploadTask().execute(count + "", "pk" + count + ".jpg");
