How to set data from arraylist to listview

How to set data from arraylist to listview - java

This is my adapter class:
public class MyAdapter extends ArrayAdapter {
private Context context;
private LayoutInflater inflater;
private List<HashMap<String, String>> aList=new ArrayList<HashMap<String,String>>();
int[] to;
public MyAdapter(Context context, List<HashMap<String, String>> aList) {
super(context, R.layout.layoutarray, aList);
this.context = context;
this.aList = aList;
inflater = LayoutInflater.from(context);
}
HashMap<String, String> m;
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (null == convertView) {
convertView = inflater.inflate(R.layout.layoutarray, parent, false);
}
TextView title1=(TextView)convertView.findViewById(R.id.posttitle);
TextView description1=(TextView)convertView.findViewById(R.id.postdesc);
//TextView image1=(ImageView)rootView.findViewById(R.id.postimage);
TextView date=(TextView)convertView.findViewById(R.id.postdate);
ImageView image1=(ImageView)convertView.findViewById(R.id.postimage);
title1.setText(aList.get(aList.get(0).get("Title")));
// Picasso.with(context).load(m.get("Image")).into(image1);
return convertView;
}
}
This is my Activity:
#Override

final View rootView = inflater.inflate(R.layout.aa, container, false);
Firebase.setAndroidContext(getActivity());

I want to set the values from my List to text view (which is a listiview).
but when i set it it is showing only first data in the listview. i am not understanding what is going wrong ,how to fetch all the data from List and set it to listview.
please help me to solve this..

I guess you are getting the same value each time. Get value for the right position in your adapter. Something like this:
title1.setText(aList.get(position).get("Title"));

When click on tab, add same data in ListView continue

I am using Tab Layout. I am showing data in ListView inside ListFragment. Data is showing in ListView but problem is when we press tabb again, same data will add in Listview. So every time continue same data add in listView.
Code here-
public class HomeFragments extends ListFragment {
int[] ust_icon = {R.drawable.title,R.drawable.t2,R.drawable.t2};
String[] live_on = {"NA","NA","NA"};
String[] total_subtopics = {"3","3","3"};
String[] title = {"semiconductor devices ##","Equations of state ##","pn junction ##"};
String[] pos = {"1","5","6"};
String[] completed_subtopics = {"3","3","3"};
String[] live = {"false","false","false"};
String[] id = {"13","14","15"};
ArrayList<HashMap<String,String>> data = new ArrayList<HashMap<String, String>>();
SimpleAdapter adapter;
public HomeFragments() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_home_fragments, container, false);
HashMap<String, String> map = new HashMap<String, String>();
for (int i=0;i<3;i++)
{
map = new HashMap<String, String>();
map.put("ust_icon", Integer.toString(ust_icon[i]));
map.put("live_on",live_on[i]);
map.put("total_subtopics",total_subtopics[i]);
map.put("title",title[i]);
map.put("pos",pos[i]);
map.put("completed_subtopics",completed_subtopics[i]);
map.put("live",live[i]);
map.put("id",id[i]);
data.add(map);
}
String[] from = {"ust_icon","live_on","total_subtopics","title","pos","completed_subtopics","live","id"};
int[] to = {R.id.img1,R.id.txt1,R.id.txt2,R.id.txt3,R.id.txt4,R.id.txt5,R.id.txt6,R.id.txt7};
adapter = new SimpleAdapter(getActivity(),data, R.layout.list1, from, to);
setListAdapter(adapter);
return view;
}
#Override
public void onStart() {
super.onStart();
}
}
how to resolve this issue Please help....

I think I have your answer. Just wait for me a couple minute when I got home and then I’ll answer you ok?
Edit:
Try to construct your data and set your adapter in onActivityCreated()
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_home_fragments, container, false);
return view;
}
and
#Override
public void onActivityCreated(#Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
HashMap<String, String> map = new HashMap<String, String>();
for (int i=0;i<3;i++)
{
map = new HashMap<String, String>();
map.put("ust_icon", Integer.toString(ust_icon[i]));
map.put("live_on",live_on[i]);
map.put("total_subtopics",total_subtopics[i]);
map.put("title",title[i]);
map.put("pos",pos[i]);
map.put("completed_subtopics",completed_subtopics[i]);
map.put("live",live[i]);
map.put("id",id[i]);
data.add(map);
}
String[] from = {"ust_icon","live_on","total_subtopics","title","pos","completed_subtopics","live","id"};
int[] to = {R.id.img1,R.id.txt1,R.id.txt2,R.id.txt3,R.id.txt4,R.id.txt5,R.id.txt6,R.id.txt7};
adapter = new SimpleAdapter(getActivity(),data, R.layout.list1, from, to);
setListAdapter(adapter);
}
if the code above not working, try to replace this:
ArrayList<HashMap<String,String>> data = new ArrayList<HashMap<String, String>>();
by this: ArrayList<HashMap<String,String>> data;
and then in your onCreateView : data = new ArrayList<HashMap<String, String>>();

Try adding condition to your code like i did below.i just created boolean variable called check.if tab opens first time it will set listview as well as set it's value to true.now condition wont run and you will not get listview element add again and again
public class HomeFragments extends ListFragment {
int[] ust_icon = {R.drawable.title,R.drawable.t2,R.drawable.t2};
String[] live_on = {"NA","NA","NA"};
String[] total_subtopics = {"3","3","3"};
String[] title = {"semiconductor devices ##","Equations of state ##","pnjunction ##"};
String[] pos = {"1","5","6"};
String[] completed_subtopics = {"3","3","3"};
String[] live = {"false","false","false"};
String[] id = {"13","14","15"};
public static final boolean check = false;
ArrayList<HashMap<String,String>> data = new ArrayList<HashMap<String, String>>();
SimpleAdapter adapter;
public HomeFragments() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_home_fragments, container, false);
HashMap<String, String> map = new HashMap<String, String>();
for (int i=0;i<3;i++)
{
map = new HashMap<String, String>();
map.put("ust_icon", Integer.toString(ust_icon[i]));
map.put("live_on",live_on[i]);
map.put("total_subtopics",total_subtopics[i]);
map.put("title",title[i]);
map.put("pos",pos[i]);
map.put("completed_subtopics",completed_subtopics[i]);
map.put("live",live[i]);
map.put("id",id[i]);
data.add(map);
}
if(check == false)
{
String[] from = {"ust_icon","live_on","total_subtopics","title","pos","completed_subtopics","live","id"};
int[] to = {R.id.img1,R.id.txt1,R.id.txt2,R.id.txt3,R.id.txt4,R.id.txt5,R.id.txt6,R.id.txt7};
adapter = new SimpleAdapter(getActivity(),data, R.layout.list1, from, to);
setListAdapter(adapter);
check = true;
}
return view;
}

How can I populate a spinner with my Firebase database?

I want to populate a spinner instead of a ListView with data from Firebase.
The code below works fine with ListView. But how can I replace the ListView with a spinner? Hope someone can help me with this.
My research:
Firebase data to Spinner
Populatate the spinner from Firebase database
Here is my Main Activity:
public class Ansattliste extends AppCompatActivity {
DatabaseReference databaseAnsatt;
ListView lvansattliste;
Button btnleggtilansatt;
List<Ansatt> listansatt;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_ansattliste);
databaseAnsatt = FirebaseDatabase.getInstance().getReference("Ansatte");
lvansattliste = (ListView)findViewById(R.id.lvansattliste);
listansatt = new ArrayList<>();
btnleggtilansatt = (Button)findViewById(R.id.btnleggtilansatt);
btnleggtilansatt.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent leggtil = new Intent(Ansattliste.this, Leggtilansatt.class);
startActivity(leggtil);
}
});
}
#Override
protected void onStart() {
super.onStart();
databaseAnsatt.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
listansatt.clear();
for (DataSnapshot ansattSnapshot : dataSnapshot.getChildren()) {
final Ansatt ansatt = ansattSnapshot.getValue(Ansatt.class);
listansatt.add(ansatt);
final listAnsatt adapter = new listAnsatt(Ansattliste.this, listansatt);
lvansattliste.setAdapter(adapter);
adapter.notifyDataSetChanged();
}
}
#Override
public void onCancelled (DatabaseError databaseError){
}
});
}
}
And my Adapter:
public class listAnsatt extends ArrayAdapter<Ansatt> {
private Activity context;
private List<Ansatt> listansatt;
public listAnsatt(Activity context, List<Ansatt> listansatt) {
super(context, R.layout.list_ansatt, listansatt);
this.context = context;
this.listansatt = listansatt;
}
#NonNull
#Override
public View getView(int position, #Nullable View convertView, #NonNull ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View listViewItem = inflater.inflate(R.layout.list_ansatt, null, true);
TextView tvansattnavn = (TextView) listViewItem.findViewById(R.id.tvansattnavn);
TextView tvansaattnr = (TextView) listViewItem.findViewById(R.id.tvansattnr);
Ansatt ansatt = listansatt.get(position);
tvansattnavn.setText(ansatt.getAnsattnavn());
tvansaattnr.setText(ansatt.getAnsattnr());
return listViewItem;
}
Firebase:
Firebase

You'd do something like following (I've adapted from Kotlin code I have here so possibility of some syntax errors)...have assumed for illustration that getAnsattnavn() is value you want to show in spinner. You'd still have listansatt which presumably you'd look up when item is selected in spinner.
In onDataChange:
List<String> optionList = new ArrayList<>();
for (DataSnapshot ansattSnapshot : dataSnapshot.getChildren()) {
final Ansatt ansatt = ansattSnapshot.getValue(Ansatt.class);
optionList.add(ansatt.getAnsattnavn());
listansatt.add(ansatt);
}
ArrayAdapter<CharSequence> adapter = new ArrayAdapter(this, android.R.layout.simple_spinner_item, optionList);
spinnerControl.setAdapter(adapter);

If you are using recycler view then your adapter should also extends recycler view instead of Base Adapter. For eg.
public class MyRecyclerAdapter extends RecyclerView.Adapter<MyRecyclerAdapter.CustomViewHolder> {
private List<FeedItem> feedItemList;
private Context mContext;
public MyRecyclerAdapter(Context context, List<FeedItem> feedItemList) {
this.feedItemList = feedItemList;
this.mContext = context;
}
#Override
public CustomViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.list_row, null);
CustomViewHolder viewHolder = new CustomViewHolder(view);
return viewHolder;
}
#Override
public void onBindViewHolder(CustomViewHolder customViewHolder, int i) {
FeedItem feedItem = feedItemList.get(i);
//Download image using picasso library
Picasso.with(mContext).load(feedItem.getThumbnail())
.error(R.drawable.placeholder)
.placeholder(R.drawable.placeholder)
.into(customViewHolder.imageView);
//Setting text view title
customViewHolder.textView.setText(Html.fromHtml(feedItem.getTitle()));
}
#Override
public int getItemCount() {
return (null != feedItemList ? feedItemList.size() : 0);
}
}

I've made my own ListView Adapter but no data is printed

This is what i have tried, but my ListView doesn't get filled. I use a custom adapter because i wan't to change the background color of the items that't got a boolean value = true. I am using Android Studio.
Hope someone can help.
i'm new to android.
public class ShoppingListActivity extends ActionBarActivity {
private TextView header;
private ListView listView;
private CustomArrayAdapter arrayAdapter;
private ShoppingList shoppingList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_shopping_list);
header = (TextView)findViewById(R.id.textView2);
//get reference to ListView
listView = (ListView)findViewById(R.id.shoppingListItemsView);
shoppingList = (ShoppingList) getIntent().getSerializableExtra(Globals.CHOSENLISTKEY);
arrayAdapter = new CustomArrayAdapter(this, R.layout.custom_list_view, shoppingList.getItemList());
listView.setAdapter(arrayAdapter);
header.setText(shoppingList.toString());
Button btnShop = (Button) findViewById(R.id.btnShop);
btnShop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(ShoppingListActivity.this, SelectStoreActivity.class);
startActivity(intent);
}
});
}
public void setData() {
for(int i = 0; i < shoppingList.getItemList().size(); i++) {
arrayAdapter.add(shoppingList.getItemList().get(i));
}
}
}
public class CustomArrayAdapter extends ArrayAdapter<Entry> {
private int resource;
private ArrayList<Entry> list;
public CustomArrayAdapter(Context context, int resource, ArrayList<Entry> list) {
super(context, resource);
this.resource = resource;
this.list = list;
}
#Override
public View getView(int position, View convertView, ViewGroup parentGroup) {
View view = convertView;
Entry entry = list.get((position));
if(view == null) {
LayoutInflater layoutInflater = ((Activity) getContext()).getLayoutInflater();
view = layoutInflater.inflate(resource, parentGroup, false);
}
TextView textView = (TextView) view.findViewById(R.id.customName);
if(entry.getItem().isBought()) {
textView.setBackgroundColor(Color.BLUE);
}
return view;
}
}

To show data in ListView rows call setText method of TextView which is return from getView method:
TextView textView = (TextView) view.findViewById(R.id.customName);
// get Text from entry and pass it to setText method
String strTextViewData=entry.getItem()...;
textView.setText(strTextViewData);
if(entry.getItem().isBought()) {
textView.setBackgroundColor(Color.BLUE);
}

LazyList 's listview can not refresh with new arraylist

I m trying to use searchView with LazyList. In my lazyAdapter I m updating my arraylist , this works smoothly but my listview doesn't update with arrayList. This is my filer method. I suppose notifyDataSetChanged does not work.Please help how can I refresh my listview?
public void filter(String charText) {
charText = charText.toLowerCase(Locale.getDefault());
//list.clear();
list = new ArrayList<HashMap<String, String>>();
if (charText.length() == 0) {
list.addAll(arraylist);
}
else
{
for (HashMap<String, String> map : arraylist)
{
if (map.get("radio").toString().toLowerCase(Locale.getDefault()).contains(charText))
{
list.add(map);
}
}
}
notifyDataSetChanged();
}

The variable list holds a different object after the third line. You are changing this new ArrayList but the adapter still remembers the old one. Instead of
list = new ArrayList<HashMap<String, String>>();
write
list.clear();
You then work with the same object as before.

LazyList 's listview can not refresh with new arraylist
Because you are not adding new list in current Adapter of Listview before calling notifyDataSetChanged() :
Add list to adapter using addAll method:
listviewAdapter.addAll(list);
//notify data-source change to adapter
notifyDataSetChanged();
if addAll method not available then create a method in Adapter class and pass list as parameter then call add method:
public void addAll(ArrayList<HashMap<String, String>> data) {
for(String item: data) {
add(item);
}
notifyDataSetChanged();
}

public class MovieListAdapter extends BaseAdapter {

}
return griView;
