如何将我从相机拍摄的照片发送到服务器文件夹。 Gallery功能正常工作，可以将图片发送到服务器，但如果我使用Camera选项，则图像无法发送到服务器。有人可以解决这个问题。
这是我的java文件。

$file_pathi = "uploads/";
$file_path = $file_pathi . basename($_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
$query = 'insert into barang (nama, harga, kondisi, notelepon, foto) values ("'.$nama.'", "'.$harga.'", "'.$kondisi.'", "'.$notelepon.'", "http://192.168.43.226/jualan/barang_tes/'.$file_path.'")';
mysql_query($query);

您必须在调用相机意图之前保留文件路径，使用以下内容更改onClick方法：
@Override
public void onClick(View arg0) {
if(arg0==btnselectpic)
{
final CharSequence[] options = { "Take Photo", "Choose from Gallery","Cancel" };
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("Add Photo!");
builder.setItems(options, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int item) {
if (options[item].equals("Take Photo"))
{
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment.getExternalStorageDirectory(), "temp.jpg");
imagepath = f.getAbsolutePath()
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
startActivityForResult(intent, 1);
}
else if (options[item].equals("Choose from Gallery"))
{
Intent intent = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 2);
} else if (options[item].equals("Cancel")) {
dialog.dismiss();
}
}
});
builder.show();
}
else if (arg0==uploadButton) {
dialog = ProgressDialog.show(MainActivity.this, "", "Uploading file...", true);
messageText.setText("uploading started.....");
new Thread(new Runnable() {
public void run() {
uploadFile(imagepath);
//send();
}
}).start();
}
}
并在onActivityResult方法中执行以下操作以获取位图
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == 1) {
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
Bitmap b = BitmapFactory.decodeFile(imagepath, options);
imageview.setImageBitmap(b);
} else if (requestCode == 2) {
Uri selectedImage = data.getData();
imagepath = getPath(selectedImage);
String[] filePath = { MediaStore.Images.Media.DATA };
Cursor c = getContentResolver().query(selectedImage,filePath, null, null, null);
c.moveToFirst();
int columnIndex = c.getColumnIndex(filePath[0]);
String picturePath = c.getString(columnIndex);
c.close();
Bitmap thumbnail = (BitmapFactory.decodeFile(picturePath));
//Log.w("path of image from gallery......******************.........", picturePath+"");
imageview.setImageBitmap(thumbnail);
messageText.setText("Uploading file path:" +imagepath);
}
}
}
