In my application I am using a listview which displays the data from a CustomAdapter.In my arraylist I have two items.My listview shows the last added data two times instead of first item.
This is my custom Adapter:
public class NodeListViewCustomAdapter extends BaseAdapter {
LayoutInflater inflater;
Activity mActivity;
ArrayList<Node> mNodeList;
double mRecvProgress;
double mSentProgress;
String repeatSentprogress;
String repeatRecvprogress;
ViewHolder holder;
Node node;
public NodeListViewCustomAdapter(Activity aContext,Node node,ArrayList<Node> nodeList){
super();
mActivity = aContext;
this.node = node;
this.inflater = (LayoutInflater)aContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
this.mNodeList = nodeList;
}
#Override
public int getCount() {
return mNodeList.size();
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return null;
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
#Override
public void notifyDataSetChanged() {
super.notifyDataSetChanged();
}
public static class ViewHolder
{
TextView txtViewnodeTitle;
TextView sentStatustxtView;
TextView recvStatustxtView;
TextView msgsentvalue;
TextView msgrecvvalue;
TextView sentindicator;
TextView recvindicator;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if(convertView==null)
{
holder = new ViewHolder();
convertView = inflater.inflate(R.layout.nodelistitem_row, null);
} else{
holder=(ViewHolder)convertView.getTag();
}
if(node.advertise)
convertView.setBackgroundColor(Color.YELLOW);
node.advertise = false;
convertView.setBackgroundColor(Color.BLACK);
holder.txtViewnodeTitle = (TextView) convertView.findViewById(R.id.txtViewnodeTitle);
holder.sentStatustxtView = (TextView) convertView.findViewById(R.id.sentstatustxtView);
holder.recvStatustxtView = (TextView) convertView.findViewById(R.id.recvstatustextView);
holder.msgsentvalue = (TextView) convertView.findViewById(R.id.msgsenttitle);
holder.msgrecvvalue = (TextView) convertView.findViewById(R.id.msgrecvtitle);
convertView.setTag(holder);
holder.sentStatustxtView.setGravity(Gravity.LEFT);
holder.recvStatustxtView.setGravity(Gravity.LEFT);
computeProgress();
holder.txtViewnodeTitle.setText(String.valueOf(node.nodeID));
holder.msgsentvalue.setText("< "+String.valueOf(node.ms)+"/"+node.MS);
holder.sentStatustxtView.setText(repeatSentprogress);
holder.msgrecvvalue.setText("> "+String.valueOf(node.mr)+"/"+node.MR);
holder.recvStatustxtView.setText(repeatRecvprogress);
return convertView;
}
private void computeProgress() {
mSentProgress = ((double)node.ms/(double)node.MS)*20;
mRecvProgress = ((double)node.mr/(double)node.MR)*20;
repeatSentprogress = new String(new char[(int)mSentProgress]).replace('\0', (char) 9608);
repeatRecvprogress = new String(new char[(int)mRecvProgress]).replace('\0', (char) 9608);
if(node.ms == node.MS)holder.sentStatustxtView.setTextColor(Color.GREEN);
else holder.sentStatustxtView.setTextColor(Color.BLUE);
if(node.mr == node.MR)holder.recvStatustxtView.setTextColor(Color.GREEN);
else holder.recvStatustxtView.setTextColor(Color.BLUE);
}
}
This is my Activity:
public class Nodes extends Activity implements OnItemClickListener {
ListView mListView;
NodeListViewCustomAdapter mNodeListAdapter;
public ArrayList <Node> mNodesList ;
TextView nodeIdView;
Timer mTimer;
Timer mInnerTimer;
int delay = 500;
int period = 500;
boolean found = false;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.nodes);
mListView = (ListView)findViewById(R.id.node_list);
mNodesList = new ArrayList<Node>();
doTimerTask();
mListView.setOnItemClickListener(this);
}
private void doTimerTask() {
mTimer = new Timer();
mTimer.scheduleAtFixedRate(new TimerTask() {
#Override
public void run() {
runOnUiThread(new Runnable() {

while(true){
try{
String PeardOutput = null;
synchronized(AndroidPeardServer.nodestatsqe){
PeardOutput = AndroidPeardServer.nodestatsqe.poll();
if (PeardOutput == null) return;
}
String msg = PeardOutput.substring(3);
process_nodeStats(msg);
mNodeListAdapter.notifyDataSetChanged();
}
catch(Exception e){
e.printStackTrace();
}
}
}
});
}
}, delay, period);
}
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
}
private void process_nodeStats(String msg) {
String[] nodeStats = msg.split(":");
String type = nodeStats[0];
int nodeID = Integer.parseInt(nodeStats[1]);
int value = Integer.parseInt(nodeStats[2]);
int cycle = Integer.parseInt(nodeStats[3]);
// Iterate through the nodelist
found = false;
for(Node node: mNodesList){
if (node.nodeID != nodeID) {
continue;
}
else found = true;
populateNode(node,type, nodeID, value, cycle);
mNodeListAdapter = new NodeListViewCustomAdapter(getParent(),node,mNodesList);
mListView.setAdapter(mNodeListAdapter);
break;
}
if (!found){
Node node = new Node();
mNodesList.add(node);
populateNode(node,type,nodeID,value,cycle);
mNodeListAdapter = new NodeListViewCustomAdapter(getParent(),node,mNodesList);
mListView.setAdapter(mNodeListAdapter);
}
}
private void populateNode(Node node,String type,int nodeId, int value, int cycle) {
node.nodeID = nodeId;
if(type.equals("MS")){
node.MS = value;
node.CS = cycle;
node.ms = 0;
}else if(type.equals("MR")){
node.MR = value;
node.CR = cycle;
node.mr = 0;
}else if(type.equals("ms")){
if(cycle==node.CS) node.ms = + value;
else node.ms = value;
}else if(type.equals("mr")){
if(cycle==node.CR) node.mr = + value;
else node.mr = value;
}else if (type.equals("NL")){
mNodesList.remove(node);
}else if(type.equals("NA")){
node.advertise = true;
}
}
//========= Node class to store in NodeList =================
public class Node {
int nodeID;
int MS; //Total Messages to Send to nodeID
int ms; //number of Messages sent so far
int MR ; //Total Messages expected from nodeID
int mr; //number of Messages received so far
int CS; //Investigation Cycle for Sending
int CR; //Investigation Cycle for Receiving
boolean advertise = false; // To know the advertisements received
}
}
I finally got tit right.I have not taken the node from the arraylist.So this line done it for me.
node = mNodeList.get(position);
Thanks for all.

I have created a custom listview adapter to fit a button, a custom chronometer and a textview. When i scroll my listview, the rows that are "hidden" refresh themselves and so chronometers, how can i keep chronometers running even if they're hidden?
I am quite new to Android development so i may have done something wrong; I know that listview refresh its rows when scrolled but maybe there's something that i missed to make chronometers running in background
public class MyCustomAdapter extends BaseAdapter {
ArrayList<String> users;
Context context;
LayoutInflater inflater = null;
public MyCustomAdapter(Activity mainActivity, ArrayList<String> usersList) {
// TODO Auto-generated constructor stub
users = usersList;
context = mainActivity;
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return users.size();
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return users.get(position);
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
private class Holder {
TextView tv;
CustomChrono cr;
Button but;
}
#Override
public View getView(final int position, View convertView, final ViewGroup parent) {
// TODO Auto-generated method stub
final Holder holder = new Holder();
View rowView;
rowView = inflater.inflate(R.layout.customized_list_view, null);
holder.tv = (TextView) rowView.findViewById(R.id.names_laps);
holder.cr = (CustomChrono) rowView.findViewById(R.id.chronometer_laps);
holder.but = (Button) rowView.findViewById(R.id.stop_button);
holder.cr.start();
holder.but.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//((ListView) parent).performItemClick(v, position, 0);
holder.cr.stop();
stopped = true;
}
});
holder.tv.setText(users.get(position));
rowView.setTag(holder);
return rowView;
}
}
Then I have my activity class where I use this adapter

//Button b;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_runner_laps);
Intent i = getIntent();
serializableManager = new SerializableManager();
runner_array = (ArrayList<String>) getIntent().getSerializableExtra("KEY");
ArrayList<Runner> running = getIntent().getExtras().getParcelableArrayList("arr2");
runners_arrList = new ArrayList<Runner>(runner_array.size());
for (String r : runner_array)
{
runners_arrList.add(new Runner(r));
}
for (int f = 0; f < runners_arrList.size();f++)
{
Log.d("Runner: " + f,runners_arrList.get(f).getName());
}
m = getIntent().getExtras().getString("booly");
for (int j = 0; j < runner_array.size(); j++) {
Runner r = new Runner(runner_array.get(j));
map.put(r, runner_array.get(j));
}
if (m!= null)
{
stopped = true;
}
list = (ListView) findViewById(R.id.laps_list);
final MyCustomAdapter adapter = new MyCustomAdapter(RunnerLaps.this,runner_array);
list.setAdapter(adapter);
//addRunners();
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override

r.setTemp(System.currentTimeMillis());
long temp = r.getTemp();
previousClickTime1 = temp;
if (previousClickTime1 != 0 && previousClickTime1 - temp < 300)
{
if (stopped == true)
{
chr.stop();
r.laps[r.counter] = chr.getText().toString();
r.increaseCounter();
Intent i = new Intent (RunnerLaps.this,Runner_Display.class);

}
}

}
Explanation:
I have a listview in my fragment. When I click one of the row of the listview it goes to another activity.In listview,I got the data from the adapter.
Inside the adapter view,I set the setOnClick().
Problem is when I click one of the row multiple time it is opening multiple activity.I want to restrict only one time click on the particular row over the listview item.
Here is my fragment where I get the listview and set the adapter-
public class HomeFragment extends Fragment{
public HomeFragment() {

This adapter set the listrow item into listview.
In ScheduleAdapter.java i set the onclick() on the convertView in which i called a GetValue class which is only implement a Asynctask to get the data and called and intent then it goes to an activity.
Means HomeFragment->ScheduleAdapter->GetValue->Scorecard
Here,
HomeFragment is fragment which have listview
ScheduleAdpter is an adapter which set data to listview which reside in homefragment
GetValue is class which implement some important task and it passed an intent and goes to an activity(It's work as a background)
ScoreCard is my activity which called after click on the row of the listview which reside in HomeFragment.
Please, help me to solve out this problem.
You can use a flag in Listview click - isListClicked, and set flag value as false in onPostexecute method of Aysnc task class -GetValue
convertView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(!isListClicked){
match_key = arr_matchKey.get(position);
MainActivity activity = (MainActivity) context;
GetValue gv = new GetValue(context);
gv.setFullUrl(match_key);
gv.setAccessToken(activity.getMyData());
gv.execute();
isListClicked = true;
}
}
});
If you want to prevent multiple activities being opened when the user spams with touches, add into your onClick event the removal of that onClickListener so that the listener won't exist after the first press.
Easy way is you can create a model class of your json object with those field you taken in holder class. And add one more boolean field isClickable with by default with true value.Now when user press a row for the first time you can set your model class field isClickable to false. Now second time when user press a row,you will get a position of row and you can check for isClickable. it will return false this time.
Model Class :
public class CountryInfoModel {
//other fields to parse json object
private boolean isClickable; //<- add one more extra field
public boolean isClickable() {
return isClickable;
}
public void setIsClickable(boolean isClickable) {
this.isClickable = isClickable;
}
}
listview click perform :
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//country_list is your list of model class List<CountryInfo>
if(country_list.get(position).isClickable())
{
//Perform your logic
country_list.get(position).setIsClickable(false);
}else{
//Do nothing : 2nd time click
}
}
});
Try creating your custom click listener for your listview and use it. In this way
public abstract class OnListItemClickListener implements OnItemClickListener {
private static final long MIN_CLICK_INTERVAL=600;
private long mLastClickTime;
public abstract void onListItemSingleClick(View parent, View view, int position, long id);
public OnListItemClickListener() {
// TODO Auto-generated constructor stub
}
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// TODO Auto-generated method stub
long currentClickTime=SystemClock.uptimeMillis();
long elapsedTime=currentClickTime-mLastClickTime;
mLastClickTime=currentClickTime;
if(elapsedTime<=MIN_CLICK_INTERVAL)
return;
onListItemSingleClick(parent, view, position, id);
}
}
I've custom adapter that populates custom listview with data fetched from server. What I want is check if adapter is empty and append data to listview if it is empty else fill the listview with data and notifyDataSetChanged. I'm implementing OnScrollListener to load more data from server. But adapter never is empty and always notifyDataSetChanged is called.

Try this way,hope this will help you to solve your problem.
public void setBusinesses(ArrayList<BusinessListData> businesses) {
imgFetcher = new BusinessListIconTask(this);
layoutInflator = LayoutInflater.from(this);
if(this.businesses == null || adapter==null){
this.businesses = new ArrayList<BusinessListData>();
adapter= new BusinessListDataAdapter(this,imgFetcher,layoutInflator,this.businesses);
businessList.setAdapter(adapter);
}
this.businesses.addAll(businesses);
adapter.notifyDataSetChanged();
}
You have the adapter object in your setBusinesses Method. You just need to check the size of the adapter too as follows which is solve your problem.
if(adapter !=null && adapter.getCount()>0)
{
this.adapter.notifyDataSetChanged();
}
else
{
this.adapter= new BusinessListDataAdapter(this,
this.imgFetcher, this.layoutInflator, this.businesses);
businessList.setAdapter(adapter);
}
this will check the size of your BusinessListData object in the adapter and this will not initialize the adapter again and again.
Hope this Solves your problem.
Thank You!
Change use of OnScrollListener. Use Asynctask class and onPreExecute() set adapter as null. Load data in doInBackground() method and call custom adapter in onPostExecute(). I hope it 'll work fine.
I have an Vertical listview i want listview should be closed. For example if the last item is reached in Listview then show the first item below the last item.

i am passing the facebook friend list to the listview.please provide some suggestion
Thanks in advance
For filter the listview using edit text at the top .
I used this code.
Make one list called searchResults than in onTextChanged method of edittext simply do this-
String searchString = `your edittext object`.getText().toString();
int textLength = searchString.length();
searchResults.clear();
for (int i = 0; i < `your main list of items`.size(); i++) {
String name = `your main list of items`.get(i).get("`your key`").toString();
System.out.println(" name " + name);
if (textLength <= title.length()) {
// compare the String in EditText with Names in the
// ArrayList
if (searchString.equalsIgnoreCase(name.substring(0, textLength))) {
searchResults.add(`your main list of items`.get(i));
System.out.println("the array list is "+ `your main list of items`.get(i));
mAdapter = new Adapter(this, searchResults);
`your ListView object`.setAdapter(mAdapter);
}
}
}
if (searchResults.isEmpty()) {
Toast toast = Toast.makeText(getApplicationContext(),"No Items Matched",Toast.LENGTH_SHORT);
toast.show();
mAdapter = new Adapter(this, searchResults);
`your ListView object`.setAdapter(mAdapter);
}
mAdapter.notifyDataSetChanged();
and on setOnItemClickListener just check searchResults.isEmpty() if true than use your your main list of items and if false than use searchResults list.
May be it will help you.try this.
change your filter with following code:
#Override
public Filter getFilter() {
//Log.d("in filter", "yes");
return new Filter() {
#Override
protected FilterResults performFiltering(CharSequence constraint) {
final FilterResults oReturn = new FilterResults();
and set your list in this function and after set your list :
oReturn.values = YourList;
and finall
return oReturn;
and in Your search.addTextChangedListener(new TextWatcher()) just in onTextChanged add following line:
adapter2.getFilter().filter(s.toString());
Try this,
adapter2=new FriendListAdapter(this);
friendsList.setAdapter(adapter2);
