[英]compressing selected image file/taken from camera
試圖讓用戶添加個人資料圖片,但我想在將圖像文件發送到服務器之前對其進行壓縮。
我怎樣才能壓縮:
文件 imageFile = new File(resultUri.getPath());
嘗試並搜索但無法開始工作
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
CropImage.ActivityResult result = CropImage.getActivityResult(data);
if (resultCode == RESULT_OK) {
Uri resultUri = result.getUri();
btnConfirm.setVisibility(View.VISIBLE);
btnConfirm.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
File imageFile = new File(resultUri.getPath());
progressDialog.show();
AndroidNetworking.upload("https://myweb.com/uploadImg.php")
.addMultipartFile("image", imageFile)
很想得到一些建議,在此先感謝。
檢查這個
Uri selectedImage = imageReturnedIntent.getData();
InputStream imageStream = null;
try {
imageStream = getContentResolver().openInputStream(
selectedImage);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
Bitmap bmp = BitmapFactory.decodeStream(imageStream);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
try {
stream.close();
stream = null;
} catch (IOException e) {
e.printStackTrace();
}
