我想借助intent发送捕获的图像并将图像发送到远程服务器。我正在使用下面的代码：发送捕获的图像到web服务器android
String image_str;
String URL =**************/image.php?;
ArrayList<NameValuePair> nameValuePairs;
imageview.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
TakePhoto();
}
});
private void TakePhoto() {
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
startActivityForResult(intent, 0);
}
BitmapFactory.Options btmapOptions;
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 0 && resultCode == RESULT_OK) {
if (data != null) {
/* photo = (Bitmap) data.getExtras().get("data");
imageview.setImageBitmap(photo); *//* this is image view where you want to set image*/
Log.d("camera ---- > ", "" + data.getExtras().get("data"));
Toast.makeText(getApplicationContext(), getLastImageId(), Toast.LENGTH_LONG).show();
btmapOptions = new BitmapFactory.Options();
photo = BitmapFactory.decodeFile(getLastImageId(), btmapOptions);
imageview.setImageBitmap(photo);
}
// sendImg();
dialog = ProgressDialog.show(surakhaActivity.this, "", "Uploading file...", true);
new Thread(new Runnable() {
public void run() {
runOnUiThread(new Runnable() {
public void run() {
}
});
sendImg();
// Toast.makeText(getBaseContext(), response, Toast.LENGTH_LONG).show();
}
}).start();
}
}
private String getLastImageId() {
final String[] imageColumns = { MediaStore.Images.Media._ID,
MediaStore.Images.Media.DATA };
final String imageOrderBy = MediaStore.Images.Media._ID + " DESC";
Cursor imageCursor = managedQuery(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, imageColumns,
null, null, imageOrderBy);
if (imageCursor.moveToFirst()) {
int id = imageCursor.getInt(imageCursor
.getColumnIndex(MediaStore.Images.Media._ID));
String fullPath = imageCursor.getString(imageCursor
.getColumnIndex(MediaStore.Images.Media.DATA));
imageCursor.close();
return fullPath;
} else {
return "no path";
}
}
InputStream inputStream;
File f;
public String convertResponseToString(HttpResponse response) throws IllegalStateException, IOException {
String res = "";
StringBuffer buffer = new StringBuffer();
inputStream = response.getEntity().getContent();
int contentLength = (int) response.getEntity().getContentLength(); //getting content length…..
Toast.makeText(surakhaActivity.this, "contentLength : " + contentLength, Toast.LENGTH_LONG).show();
if (contentLength < 0) {
}
else {
byte[] data = new byte[512];
int len = 0;
try {
while (-1 != (len = inputStream.read(data))) {
buffer.append(new String(data, 0, len)); //converting to string and appending to stringbuffer…..
}
}
catch (IOException e) {
e.printStackTrace();
}
try {
inputStream.close(); // closing the stream…..
}
catch (IOException e) {
e.printStackTrace();
}
res = buffer.toString(); // converting stringbuffer to string…..
// Toast.makeText(MainActivity.this, "Result : " + res, Toast.LENGTH_LONG).show();
}
return res;
}
public void sendImg() {
ByteArrayOutputStream stream = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.PNG, 90, stream); //compress to which format you want.
byte [] byte_arr = stream.toByteArray();
image_str = Base64.encodeBytes(byte_arr);
nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("imgdata",image_str));
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(URL);
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
the_string_response = convertResponseToString(response);
// editor.putString("imgRes", the_string_response);editor.commit();
Toast.makeText(surakhaActivity.this, "Response " + the_string_response, Toast.LENGTH_LONG).show();
}
catch(Exception e) {
Toast.makeText(surakhaActivity.this, "ERROR " + e.getMessage(), Toast.LENGTH_LONG).show();
}
dialog.dismiss();
this.finish();
}
}
但捕获图像和发送进度对话框运行无限且图像不发送。
