I really have no idea how to do that..can anyone help..I will post up java/xml code and its adapters following please have look ..I haven't done anything in demo fragment..what should I do in demo fragment???
java:
public class JavaFragment extends Fragment {
private RecyclerView recyclerView;
private NextSLJavaAdapter adapter;
private NextSLModel DescriptList;
ProgressDialog progressDialog;
public JavaFragment() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.nextsl_layout, container, false);
}
@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
Toolbar toolbar = (Toolbar) getView().findViewById(R.id. toolbar );
// setSupportActionBar( toolbar );
//if (getSupportActionBar() != null) {
// getSupportActionBar().setDisplayHomeAsUpEnabled(true);
// getSupportActionBar().setDisplayShowHomeEnabled(true);
//}
progressDialog = new ProgressDialog(getContext());
progressDialog.setMessage("Loading....");
progressDialog.show();
Intent intent = getActivity().getIntent();
String title = intent.getStringExtra("title");
//getSupportActionBar().setTitle(title);
String id = intent.getStringExtra("idSLnext");
Log.e("ashwini", String.valueOf(id));

Solution 1:
There two way to add view dynamically .
you create you
xmlfile .then usingLayoutInflateryou lnflater that xml to yourview.Or You can create view dynamically like var
textview=TextView()then textview.text="xyz"
You need relativelayout or linearlayout where will add those will using addView(); method.
But i condition you have declare your view then you can customize at runtime.
you can check the example
Solution 2:
Remote code injection is not supported from the very beginning in android. The framework developers may have thought from the security perspective as well as the limited computation that a mobiles have. Please note android studio build process converts these java, xml files into dex files which can't be done in runtime so its not supported.
Important For performance reasons, view inflation relies heavily on pre-processing of XML files that is done at build time. Therefore, it is not currently possible to use LayoutInflater with an XmlPullParser over a plain XML file at runtime.
The alternative approach is to use some JSON format for the views and properties and it will draw the widgets dynamically on a blank canvas will add it to the layout parent.
for example.
{
"type": "LinearLayout",
"orientation": "vertical",
"padding": "16dp",
"children": [{
"layout_width": "200dp",
"gravity": "center",
"type": "TextView",
"text": "@{user.profile.name}"
}, {
"type": "HorizontalProgressBar",
"layout_width": "200dp",
"layout_marginTop": "8dp",
"max": 6000,
"progress": "@{user.profile.experience}"
}]
}
This will add a LinearLayout with Childerns as TextView, HorizontalScrollBar. and data can also be inserted like below.
{
"user": {
"profile": {
"name": "John Doe",
"experience": 4192
}
}
}
