CustomGrid is my GridView adapter and MainGrid is the fragment in which I want to display the GridView. I've done this but it is not working. What should I do?
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.main_xml, container, false);
CustomGrid adapter = new CustomGrid(MainGrid.this, web, imageId);
GridView grid = (GridView) view.findViewById(R.id.grid);
grid.setAdapter(adapter);
toolbar = (Toolbar)view.findViewById(R.id.fab_toolbar);
setupToolbar();
return view;
}
What you are doing wrong is, you are sending the context of fragment to adapter which is wrong. Try this
Activity act;
In onCreateView
act = getActivity();
And then
CustomGrid adapter = new CustomGrid(act, web, imageId);
Hope this helps

it says IllegalArgumentException: No view found for id for fragment when I'm trying to setview.I know problem lies at 3rd and 4th line. it's News.java file news is a fragment.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getActivity().setContentView(R.layout.fragment_news);
listView = (ListView) getActivity().findViewById(R.id.list);
feedItems = new ArrayList<FeedItem>();
listAdapter = new FeedListAdapter(this, feedItems);
listView.setAdapter(listAdapter);
Fragment.java file is look like below code :
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_news, container, false);
//ButterKnife.bind(this, view);
init(view);
return view;
}
after that in init method type below code:
private void init(View view){
listView = (ListView) view.findViewById(R.id.list);
feedItems = new ArrayList<FeedItem>();
listAdapter = new FeedListAdapter(this, feedItems);
listView.setAdapter(listAdapter);
}
also u don't forgot to extends Fragment
enter image description hereBelow is the coding i have and it seems i have problem on the
AgentAdapter adapter = new AgentAdapter(getActivity(), R.layout.list_agent, member_names, profile_pics);
How do i use image and text together for the list adapter i have in my fragment? Please help.
public class AgentFragment extends Fragment{
String[] member_names;
TypedArray profile_pics;
ListView mylistview;
String[] agentname={"Robert","Shanni","Rachel","Mady","Nikhil"};
Integer [] imgid = {R.drawable.robert,R.drawable.shanni,R.drawable.rachael,R.drawable.maddy_pic,R.drawable.nikhil_pic};
public AgentFragment(){
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.list_layout1, null);
setupList(view);
return view;
}
private void setupList(View view){
AgentAdapter adapter = new AgentAdapter(getActivity(), R.layout.list_agent, member_names, profile_pics);
mylistview = (ListView) view.findViewById(R.id.listView);
mylistview.setAdapter(adapter);
}
}
Since its possible that the fragment has not been placed in any activity at runtime you can afford for this by changing the getActivity() to be the context from the view parameter:
private void setupList(View view){
AgentAdapter adapter = new AgentAdapter(view.getContext(), R.layout.list_agent, member_names, profile_pics);
mylistview = (ListView) view.findViewById(R.id.listView);
mylistview.setAdapter(adapter);
}
I am converting an existing activity (SherlockActivity) into fragment (SherlockListFragment) in order to use tabs.
The fragment returns a onCreateView when created and is using the following code.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
/** Creating array adapter to set data in listview */
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity().getBaseContext(), android.R.layout.simple_list_item_multiple_choice, android_versions);
/** Setting the array adapter to the listview */
setListAdapter(adapter);
return super.onCreateView(inflater, container, savedInstanceState);
}
That works fine but as I was doing in my activity I want to update the list view with my own content after I finish fetching it from the server.
ListView listContent = (ListView) getView().findViewById(R.id.contentlist);
listContent.setAdapter(myAdapter);
Whatever I have researched so far, I am fetching the listview through activity and setting my adapter to it but that is having no effect on fragment view and it remains the same.
Question is: How can I update listView from outside onCreateView?
First, make your listview a global var. Then set its value on the onCreateView function:
ListView list;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.activity_placelist, container, false);
list = rootView.findViewById(/*your id*/)
/** Creating array adapter to set data in listview */
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity().getBaseContext(), android.R.layout.simple_list_item_multiple_choice, android_versions);
/** Setting the array adapter to the listview */
setListAdapter(adapter);
return super.onCreateView(inflater, container, savedInstanceState);
}
//change your listview content here when refresh or something else
public void updateListView(){
List l = /*fetch new data from server*/
listAdapter.addAll(l);
listAdapter.notifyDataSetChanged();
}
ListView list;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.activity_placelist, container, false);
list = rootView.findViewById(/*your id*/)
/** Creating array adapter to set data in listview */
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity().getBaseContext(), android.R.layout.simple_list_item_multiple_choice, android_versions);
/** Setting the array adapter to the listview */
setListAdapter(adapter);
return rootView;
}
from here android versions must be a arraylist or string array or hashmap
This question already exists:
Spinner will not populate and won't set arrayadapter
Closed 8 years ago.
My app redirects me to a different screen from my home with the tap of a button. Once, i reach my city screen my spinner is visible. But it doesn't contain any elements from my array. Nothing force closes or anything, but it doesn't work.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_city);
if (savedInstanceState == null) {
getFragmentManager().beginTransaction().add(R.id.container, new PlaceholderFragment()).commit();
}
}
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_city, container, false);
String[] test = {"test1", "test2"};
Spinner spin = (Spinner) v.findViewById(R.id.countries);
ArrayAdapter<String> adapt = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, test);
adapt.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spin.setAdapter(adapt);
return v;
}
You need to have the below.
public static PlaceHolderFragment extends Fragment
{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_city, container, false);
String[] test = {"test1", "test2"};
Spinner spin = (Spinner) v.findViewById(R.id.countries);
ArrayAdapter<String> adapt = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_spinner_item, test);
adapt.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spin.setAdapter(adapt);
return v;
}
}
Also use getActivity() to get the context of hosting activity.
I want a custom row, so I am using a List View in an xml and inflating into a fragment. I am very confused of how to set the adapter for the list View.
I created a new adapter which extends Base Adapter. In the getView method, I really don't know what context to pass while inflating the row.xml layout.
How do I set the adapter for the list view and where?
public class ResultsFragment extends Fragment{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.results_layout, container, false);
listView = (ListView)v.findViewById(R.id.results);
return v;
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
loadPage(dataBean.getWhat(), dataBean.getWhere(), dataBean.getPageStart());
//resultsAdapter.setRssData(rssData);
//setListAdapter(resultsAdapter);
}
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
Context context = getActivity().getApplicationContext();
resultsAdapter = new ResultsAdapter(context);
}
/**
* Set List Adapter
*/
private void setAdapter(){
if(listView.getAdapter() == null){
listView.setAdapter(resultsAdapter);
}
else{
resultsAdapter.notifyDataSetChanged();
}
}
}
You must extend Listfragment (instead of Fragment), and using its ListFragment.setListAdapter to set your adapter. In the adapter getView() inflate your row.. that s all
If you do not want to change your extended class, you should use listview.setAdapter(...) method. As you see in my example :
ListView productList= (ListView) getActivity().findViewById(R.id.product_list);
SampleAdapter adapter = new SampleAdapter(getActivity());
adapter.add(new SampleItem(
"Sunny LCD TV 2\" SN022L66-T1 Full HD",
R.drawable.product_sample_pic);
productList.setAdapter(adapter);
