我想检查不到1 MB的图片并使用Android中的排球库上传到远程服务器.....请帮帮我。
对于选择的图片，我使用以下代码：
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"),PICK_IMAGE_REQUEST);
在活动结果中我使用：
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data)
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
try {
if (Build.VERSION.SDK_INT>19){
}else {
Uri filePath = data.getData();
File file = new File(filePath.getPath());
int length = (int) file.length();
double lengthkb = length / 1024;
if (lengthkb > 0.0D) {
lengthmb = lengthkb / 1024;
Log.d("picsize", lengthmb + "");
} else {
File file2 = new File(getPath(filePath));
int length2 = (int) file2.length();
double lengthkb2 = length2 / 1024;
lengthmb = lengthkb2 / 1024;
Log.d("picsize", lengthmb + "");
}
bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), filePath); imageViewProfileImage.setImageBitmap(bitmap); }
} catch(IOException e){
e.printStackTrace();
}
}
}
