Hola estoy enviando imágenes y texto al servicio web php utilizando el siguiente código.Cómo enviar varias imágenes al servidor usando MultipartEntity desde android
try {
HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpPost httpPost = new HttpPost(URL);
MultipartEntity entity = new MultipartEntity(
HttpMultipartMode.BROWSER_COMPATIBLE);
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.JPEG, 75, bos);
byte[] data = bos.toByteArray();
entity.addPart("files[]",
new ByteArrayBody(data, "myImage.jpg"));
entity.addPart("message0", new StringBody(caption.getText()
.toString()));
httpPost.setEntity(entity);
HttpResponse response = httpClient.execute(httpPost,
localContext);
BufferedReader reader = new BufferedReader(
new InputStreamReader(
response.getEntity().getContent(), "UTF-8"));
String sResponse = reader.readLine();
return sResponse;
} catch (Exception e) {
if (dialog.isShowing())
dialog.dismiss();
Toast.makeText(ImageUpload.this, e.getMessage(),
Toast.LENGTH_LONG).show();
Log.e(e.getClass().getName(), e.getMessage(), e);
return null;
}
}
Funciona perfectamente. Pero esto es solo para enviar una imagen. Ahora envío 5 imágenes y texto con él.
Ejemplo: - Image1 - Texto1
Image2 - Texto 2 etc ..
Así que estoy confundir sobre cómo almacenar 5 imágenes una por una y, al final de presentar haga clic en enviar imágenes y texto asociados al servidor.
Me sale obtener solo la imagen de la cámara.
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(
Intent.createChooser(intent, "Select Picture"),
PICK_IMAGE);
public void onActivityResult_photo(int requestCode, int resultCode,
Intent data) {
// TODO Auto-generated method stub
if (resultCode == RESULT_OK) {
if (data != null) {
mImageCaptureUri = data.getData();
display(mImageCaptureUri);
} else {
Toast.makeText(CustomTabActivity.mTabHost.getContext(),
"No photo selected..", Toast.LENGTH_SHORT).show();
}
}
}
private String display(Uri mImageCaptureUri2) {
// TODO Auto-generated method stub
String base64string = null;
try {
if (mImageCaptureUri2 != null) {
System.gc();
selectedImagePath = getPath(mImageCaptureUri2);
File filenew = new File(selectedImagePath);
int file_size = Integer.parseInt(String.valueOf(filenew
.length()/1024));
if (file_size <= 10000) {
PD1 = ProgressDialog.show(
CustomTabActivity.mTabHost.getContext(), "",
"Loading...");
Handler refresh = new Handler(Looper.getMainLooper());
refresh.post(new Runnable() {
public void run() {
PD1.setCancelable(true);
Bitmap newbitmap;
newbitmap = decodeFile(selectedImagePath);
ByteArrayOutputStream bs = new ByteArrayOutputStream();
newbitmap.compress(Bitmap.CompressFormat.PNG, 50,
bs);
img.setVisibility(View.VISIBLE);
img.setImageBitmap(newbitmap);
byte[] abc = bitmapToByteArray(newbitmap);
if (txt_phototext.getText().toString().equals("")) {
submit.put(abc, "");
} else {
submit.put(abc, txt_phototext.getText()
.toString());
// executeMultipartPost();
}
PD1.dismiss();
}
});
} else {
AlertDialog.Builder alertbox = new AlertDialog.Builder(
CustomTabActivity.mTabHost.getContext());
alertbox.setMessage("Take Image Size Less than 10 MB");
alertbox.setNeutralButton("Ok",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0,
int arg1) {
finish();
}
});
alertbox.show();
}
} else {
System.out.println("===============NULL========");
}
} catch (Exception e) {
// // TODO Auto-generated catch block
// e.printStackTrace();
}
return base64string;
}
static Bitmap decodeFile(String str) {
try {
// decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeStream(new FileInputStream(str), null, o);
// Find the correct scale value. It should be the power of 2.
final int REQUIRED_SIZE = 70;
int width_tmp = o.outWidth, height_tmp = o.outHeight;
int scale = 1;
while (true) {
if (width_tmp/2 < REQUIRED_SIZE
|| height_tmp/2 < REQUIRED_SIZE)
break;
width_tmp /= 2;
height_tmp /= 2;
scale++;
}
// decode with inSampleSize
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize = scale;
return BitmapFactory.decodeStream(new FileInputStream(str), null,
o2);
} catch (FileNotFoundException e) {
}
return null;
}
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;
}
Así que finalmente estoy atascado sobre esto, por favor ayuda.
