Android 在片段中上载文件
我试图在服务器上上传一个图像，这是我用来从android片段上传文件的代码：Android 在片段中上载文件,android,android-fragments,Android,Android Fragments,我试图在服务器上上传一个图像，这是我用来从android片段上传文件的代码： class Uploader{ String selectedImagePath; String fileSize; String date; Uploader(String selectedImagePath, String fileSize, String date){ this.selectedImagePath=selectedImagePath;
class Uploader{
String selectedImagePath;
String fileSize;
String date;
Uploader(String selectedImagePath, String fileSize, String date){
this.selectedImagePath=selectedImagePath;
this.fileSize=fileSize;
this.date=date;
}
void upload(){
SharedPreferences pref = SpaceFragment.this.getActivity().getSharedPreferences("currentuser", 0);
String name = pref.getString("username", null);
String param2 = name;
String fileNameArray[] = selectedImagePath.split("/");
String fileName = fileNameArray[fileNameArray.length-1];
SendHttpRequestTask t = new SendHttpRequestTask();
Toast.makeText(SpaceFragment.this.getActivity(), "CURRENTLY UPLOADING "+selectedImage+","+param2, Toast.LENGTH_LONG).show();
String[] params = new String[]{url, selectedImagePath, param2};
t.execute(params);
}
private class SendHttpRequestTask extends AsyncTask<String, Void, String> {
ProgressDialog progressDialog;
@Override

super.onPreExecute();
progressDialog = new ProgressDialog(SpaceFragment.this.getActivity());
progressDialog.setMessage("Uploading File. Please wait");
progressDialog.setCancelable(false);
progressDialog.show();
}
@Override
protected String doInBackground(String... params) {

}
catch(Throwable t) {
t.printStackTrace();
}
return null;

@Override

mySQLiteAdapter = new DriveDatabaseAdapter(SpaceFragment.this.getActivity().getApplicationContext());

以下是我的完整代码，以防它有助于发现问题：peer在您向其写入时关闭了连接it@maveňツ 怎么会？我没听懂你的话？我怎么才能不关上它呢？
