I am trying to retrieve data from parse,therefore I need to make a custom adapter for the listview but its not working,I created a custom adapter but the listview is not showing and I can't figure out what is the problem.
I am getting no errors or crashes so I can't point the exact problem.
This is what I have done:
The adapter:
public class MyListView extends BaseAdapter {
private final ArrayList<HashMap<String, String>> contentList;
private static LayoutInflater inflater = null;
public MyListView(Activity a, ArrayList<HashMap<String, String>> contentForList) {
this.contentList = contentForList;
inflater = (LayoutInflater) a.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public int getCount() {
return contentList.size();
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
View vi = convertView;
if (convertView == null)
vi = inflater.inflate(R.layout.mylist, null);
ImageView logo = (ImageView) vi.findViewById(R.id.icon); // title
TextView titleText = (TextView) vi.findViewById(R.id.title); // artist name
TextView subtitleText = (TextView) vi.findViewById(R.id.subtitle);
HashMap<String, String> info = new HashMap<String, String>();
info = contentList.get(position);
String title = (String) info.get("businessname");
String peopleinBusiness = (String) info.get("peopleinbusiness");
// Setting all values in listview
titleText.setText(title);
subtitleText.setText(peopleinBusiness);
// Bitmap bmp = (Bitmap) info.get("photo");
// logo.setImageBitmap(bmp);
return vi;
}
}
listView XML:

}

feedListView.setAdapter(listview);
listview.notifyDataSetChanged();
}else{
Log.e("findinBackground","Failed");
e.printStackTrace();
}
}
});
Thank you !!
I can't believe I spend so much time only to figure out I was missing a " _ " .
I changed this:
ParseQuery<ParseObject> query = ParseQuery.getQuery("User");
To this:
ParseQuery<ParseObject> query = ParseQuery.getQuery("_User");
Thank everyone !

Ive looked at a few other questions on stackoverflow about this questions however I am not able to implement this into my code as I have done things a bit differently I believe. I am still learning Android Studio so please bear with me for any stupidity.
I'm looking to create check boxes on the right side of the listview I currently have that when checked will stay in that state when the user loads the application back in.
XML:

<ListView
android:id="#+id/results_listview"
android:layout_width="wrap_content"
android:layout_height="match_parent"

while (it.hasNext()){

Map.Entry pair = (Map.Entry)it.next();
resultsMap.put("First Address", pair.getKey().toString());

I suggest the you can use Recyclerview instead listview, Try this way
public class CardViewDataAdapter extends
RecyclerView.Adapter<CardViewDataAdapter.ViewHolder> {
private List<Student> stList;
public CardViewDataAdapter(List<Student> students) {
this.stList = students;
}
// Create new views
#Override
public CardViewDataAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
// create a new view
View itemLayoutView = LayoutInflater.from(parent.getContext()).inflate(
R.layout.cardview_row, null);
// create ViewHolder
ViewHolder viewHolder = new ViewHolder(itemLayoutView);
return viewHolder;
}
#Override
public void onBindViewHolder(ViewHolder viewHolder, int position) {
final int pos = position;
viewHolder.tvName.setText(stList.get(position).getName());
viewHolder.tvEmailId.setText(stList.get(position).getEmailId());
viewHolder.chkSelected.setChecked(stList.get(position).isSelected());
viewHolder.chkSelected.setTag(stList.get(position));
viewHolder.chkSelected.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
CheckBox cb = (CheckBox) v;
Student contact = (Student) cb.getTag();
contact.setSelected(cb.isChecked());
stList.get(pos).setSelected(cb.isChecked());
Toast.makeText(
v.getContext(),
"Clicked on Checkbox: " + cb.getText() + " is "
+ cb.isChecked(), Toast.LENGTH_LONG).show();
}
});
}
// Return the size arraylist
#Override
public int getItemCount() {
return stList.size();
}
public static class ViewHolder extends RecyclerView.ViewHolder {
public TextView tvName;
public TextView tvEmailId;
public CheckBox chkSelected;
public Student singlestudent;
public ViewHolder(View itemLayoutView) {
super(itemLayoutView);
tvName = (TextView) itemLayoutView.findViewById(R.id.tvName);
tvEmailId = (TextView) itemLayoutView.findViewById(R.id.tvEmailId);
chkSelected = (CheckBox) itemLayoutView
.findViewById(R.id.chkSelected);
}
}
// method to access in activity after updating selection
public List<Student> getStudentist() {
return stList;
}
}

I am using a loop to read all the spinner elements (inside a cardview) in the listview.
But the loop gives one item less i.e. the last item.
I have included all the source code.
What may be the problem?
Is there any other way to read all the items in listview?

Check for above code in main activity. Use .getCount() instead .getChildCount()
and use .getItemAtIndex() instead .getChildAt().
I hope this solves the issue.
I am trying to make an activity that provides a list of emergency phone numbers with the ability for the user to add their own custom entries and save them. For some reason, the ListView doesn't appear on the activity. I'm pretty sure I'm doing something wrong in the CustomAdapter class that I made to hold two text boxes in each segment of the ListView.
I'm also trying to set the listView to start a phone activity with the phone number of whatever segment was touched, and I'm unsure if I'm doing this correctly.

Any help is much appreciated, thank you.
Change the super keyword line to
super(context,R.layout.phone_item, n);
Have you tried to override the getCount method of the CustomAdapter class ?
#Override
public int getCount() {
return labels.size();
}
You are setting your custom adapter outside onCreate() try to set it inside the onCreate().
I am working on an Android project in which I am currently working on chat functionality. Now, whenever an user sends a message, it is added in the ListView, which is populated by BaseAdapter. A new message is added by baseAdapterObject.add(item);.
Now, whenever an user sends a message, I am adding it directly to the already existing List and then waiting for a reply from the server confirming the message was delivered. For the first step, I would like to show a Gray checkmark, and for 2nd message received from server, I would like to show Blue checkmark.
Unfortunately, I don't know how to access the already populated list and change the background image of an ImageView. . Each message has a random-number, with which I can compare for which message I received confirmation.
Code :
public void recieveUpdatedMessageFromServer(String channelName, Map<String, Object> input){
String randomNumberFromServer = ((Map) input.get("data")).get("random").toString();
if (randomNumberFromServer.equals(randomNos)) {
messageRecieved = true;
randomNos = "";
}
chatMessagesAdapter.add(insertMap);
runOnUiThread(new Runnable() {
#Override

chatMessagesAdapter.notifyDataSetChanged();
}
});

vi = inflater.inflate(R.layout.chat_messages_row, parent, false);

ImageView userImage = (ImageView) vi.findViewById(R.id.chatImage);
TextView firstName = (TextView) vi.findViewById(R.id.personName);

chatList = data.get(position);
chatText.setText(chatList.get(ChatMessagesActivity.chatText));

I hope this much information is enuf. Kindly let me know if anything else required. Thank you. :-)
Consider using a class object to help.
For example, you can create a list of message objects:
class Message {
private String message;
private boolean gray_tick;
private boolean blue_tick;
....

Change your hashmap in your BaseAdapter to take in the corresponding object.
private ArrayList<HashMap<String, Message>> data;
From there, you can set your BaseAdapter to read these values and show the correct coloured ticks at the right time.
Hope this helps!
I write simple ListView but I have problem, I want to marquee text when I select some item from my listview but it not working I don't know why I think I write code correctly when I copy my code from listView.setOnItemSelectedListener(new OnItemSelectedListener() to listView.setOnItemClickListener(new OnItemClickListener() that's work correctly when I click, but I want this only for select.
That's my code :
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_settings);
List<HashMap<String, String>> aList = new ArrayList<HashMap<String, String>>();
for (int i = 0; i < 7; ++i) {
HashMap<String, String> hm = new HashMap<String, String>();
hm.put("firstLine", menu[i]);
hm.put("secondLine", submenu[i]);
hm.put("icon", Integer.toString(ikons[i]));
aList.add(hm);
}
String[] from = { "icon", "firstLine", "secondLine" };
int[] to = { R.id.icon, R.id.firstLine, R.id.secondLine };
SimpleAdapter adapter = new SimpleAdapter(getBaseContext(), aList,
R.layout.alarm_row, from, to);
ListView listView = (ListView) findViewById(R.id.list);
listView.setAdapter(adapter);
listView.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View view,
int arg2, long arg3) {
TextView t = (TextView) view.findViewById(R.id.secondLine);
t.setSelected(true);
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View view, int arg2,
long arg3) {
// TODO Auto-generated method stub
/*
* TextView t = (TextView) view.findViewById(R.id.secondLine);
* t.setFocusable(true); t.setSelected(true);
*/
}
});
}
XML :

I think that should work I don't have any idea what is wrong, I will be very gratefull for any help.
Try adding
t.requestFocus();
after
t.setSelected(true);
in onItemSelected
you should define a customized adapter, which extends e.g. BaseAdapter or which adapter you like and then add t.setSelected(true) in the getView method of that:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
if (convertView == null)
view = inflater.inflate(R.layout.row, null);
TextView t = (TextView) view.findViewById(R.id.secondLine);
text2.setSelected(true);
return view;
}
