Listview items changes while scrolling in android

Listview items changes while scrolling in android - android

I have a listview in which list item's background highlights while a notification arrives but the problem is that when I scroll the list then items changes highlighting. Suppose initially first item was listed when I scroll down then another item highlights. I have also used notifysetdatachanged.
Code for List Activity
public class NewPageActivity extends Fragment{
// this is my notification code when notifcation arrives
#Override
public void onResume() {
super.onResume();
IntentFilter intentFilter = new IntentFilter(
"unique_name");
mMessageReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
//extract our message from intent
String msg_for_me = intent.getStringExtra("message");
//log our message value
Log.e("TAG", "onReceive: boradcast" + msg_for_me);
if (msg_for_me.contains("&")) {
String msg1[] = msg_for_me.split("&");
if (msg1[0].contains("Waiting for acceptance...")) {
edit.putInt("newTabHighlight", sp.getInt("newTabHighlight", 0) + 1);
edit.putString("newOrder", sp.getString("newOrder", null) + "&" + msg1[1].split("=")[1]);
edit.putInt("reminderTab", sp.getInt("reminderTab", 0) + 1);
edit.putInt("newOrderCount", 1);
edit.commit();
connectToDatabase();
}
}
// code for when get data through web service and set adapter
if(getActivity()!= null) {
adapter = new customadapetr_new(dataModels, getActivity(), NewPageActivity.this);
list.setAdapter(adapter);
adapter.notifyDataSetChanged();
setListViewHeightBasedOnChildren(list);
}
}
// code for adapter where background highlights
private void setNewCardBackground(final String Order_id, final RelativeLayout MenuCard, String OrderFlag)
{
Log.e("TAG", "setNewCardBackground: " );
newOrder = sp.getString("newOrder", "null");
if (newOrder.contains("&")) {
newOrderArray = newOrder.split("&");
Log.e("TAG", "setNewCardBackground:order "+newOrderArray);
for (int i = 0; i < newOrderArray.length; i++) {

The problem could be caused by Views being recycled by the Adapter: when you scroll down/up the highlighted View gets recycled and used at another position in the ListView. You could set the background color of each View to the default color in your adapter's getView. This way the backround color of the recycled View will be set to back to normal before it's displayed again.

how to change variable value inside runnable? or how to reset data counter by button press?

I was working with trafficstats app from the below link:
datastats app github
The above app when run gives traffic data from when the device was booted.
I need the data traffic in the last hour or so.
So is there a way to initialise the counter to 0 by pressing button? So far I am stuck at this:
public class main extends Activity {
private TextView tvSupported, tvDataUsageWiFi, tvDataUsageMobile, tvDataUsageTotal;
private ListView lvApplications;
private long dataUsageTotalLast = 0;
ArrayAdapter < ApplicationItem > adapterApplications;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tvSupported = (TextView) findViewById(R.id.tvSupported);
tvDataUsageWiFi = (TextView) findViewById(R.id.tvDataUsageWiFi);
tvDataUsageMobile = (TextView) findViewById(R.id.tvDataUsageMobile);
tvDataUsageTotal = (TextView) findViewById(R.id.tvDataUsageTotal);
if (TrafficStats.getTotalRxBytes() != TrafficStats.UNSUPPORTED && TrafficStats.getTotalTxBytes() != TrafficStats.UNSUPPORTED) {
handler.postDelayed(runnable, 0);
initAdapter();
lvApplications = (ListView) findViewById(R.id.lvInstallApplication);
lvApplications.setAdapter(adapterApplications);
} else {
tvSupported.setVisibility(View.VISIBLE);
}
}
public Handler handler = new Handler();
public Runnable runnable = new Runnable() {
public void run() {
//----------------
final long mob1 = TrafficStats.getMobileRxBytes() + TrafficStats.getMobileTxBytes();
final long tot1 = TrafficStats.getTotalRxBytes() + TrafficStats.getTotalTxBytes();
//-----------------
Button bres = (Button) findViewById(R.id.resetid);
bres.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mob1 = 0;
}
});
//-----------------
long mobile = mob1;
long total = tot1;
tvDataUsageWiFi.setText("" + (total - mobile) / 1024 + " Kb");
tvDataUsageMobile.setText("" + mobile / 1024 + " Kb");
tvDataUsageTotal.setText("" + total / 1024 + " Kb");
if (dataUsageTotalLast != total) {
dataUsageTotalLast = total;
updateAdapter();
}
handler.postDelayed(runnable, 5000);
}
};
public void initAdapter() {
adapterApplications = new ArrayAdapter < ApplicationItem > (getApplicationContext(), R.layout.item_install_application) {
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ApplicationItem app = getItem(position);
final View result;
if (convertView == null) {
result = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_install_application, parent, false);
} else {
result = convertView;
}
TextView tvAppName = (TextView) result.findViewById(R.id.tvAppName);
TextView tvAppTraffic = (TextView) result.findViewById(R.id.tvAppTraffic);
// TODO: resize once
final int iconSize = Math.round(32 * getResources().getDisplayMetrics().density);
tvAppName.setCompoundDrawablesWithIntrinsicBounds(
//app.icon,
new BitmapDrawable(getResources(), Bitmap.createScaledBitmap(
((BitmapDrawable) app.getIcon(getApplicationContext().getPackageManager())).getBitmap(), iconSize, iconSize, true)),
null, null, null
);
tvAppName.setText(app.getApplicationLabel(getApplicationContext().getPackageManager()));
tvAppTraffic.setText(Integer.toString(app.getTotalUsageKb()) + " Kb");
return result;
}
#Override
public int getCount() {
return super.getCount();
}
#Override
public Filter getFilter() {
return super.getFilter();
}
};
// TODO: resize icon once
for (ApplicationInfo app:
getApplicationContext().getPackageManager().getInstalledApplications(0))
{
ApplicationItem item = ApplicationItem.create(app);
if (item != null) {
adapterApplications.add(item);
}
}
}
public void updateAdapter() {
for (int i = 0, l = adapterApplications.getCount(); i < l; i++) {
ApplicationItem app = adapterApplications.getItem(i);
app.update();
}
adapterApplications.sort(new Comparator < ApplicationItem > () {
#Override
public int compare(ApplicationItem lhs, ApplicationItem rhs) {
return (int)(rhs.getTotalUsageKb() - lhs.getTotalUsageKb());
}
});
adapterApplications.notifyDataSetChanged();
}
}
The above code is the modified snippet from the github link.
i tried by declaring a button inside a runnable , but the variable needs to be declared final which results in the variable being unchangable.

How to set listview row clickable only one time in android?

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);
}
}

How to retain the listview and the child fragment state after updating the contents of listview?

I have a listView of items.Each item has two separate fragment inside it and gets visible when the item is clicked. Inside a fragment there is another ListView and a button. The button displays a dialog through which ListView inside the fragment gets populated.The problem is when the dialog closes,the parent listview gets refreshed and as a result fragment visibility is gone. I have to click the parent list view item again to see the fragment and its content. I want the Fragment view and its updated content remain viewed after the dialog is dismissed. So someone please help me in it.
The following is my parent listView class:

The button displays a dialog through which ListView inside the fragment gets populated.
not exactly clear to me. Did you meant inside your dialog you have some action that reflects on the fragment lisview?
have to click the parent list view item again to see the fragment and its content. I want the Fragment view and its updated content remain viewed after the dialog is dismissed
What i understand here u are doing something inside child view fragment that reflects on parent view list item, you are expecting the parent item data to be updated in view and also keeping the view state here u meant to be opened the parent item as it was (when u are updating the something inside fragment or dialog whatever)
My primary answer is you keep somehow keep the position to a member reference of the activity class where you actually setting the parent list in parent item onClick callback.
keep this position and later what you have to is to call a method inside adapter to pass the position to set a perform clic on item view
you may get a hints from this link..

Highlighted items in multi-selection file-chooser are dynamically changed while scrolling listview

I have selected set of items from my sdcard folder using multi-selection file-chooser.It returns exactly selected values but the selection highlighted items (using colors) are dynamically changed while scrolling list-view..can anybody tell me how to fix it?
Here i have added my file-chooser class and adapter class..

your problem in getItem method in ListAdapter of List

try this adapter) you must determine all elements of each item in your case)
public class FileArrayAdapter extends ArrayAdapter{
private Context c;
private int id;
private List<Item>items;
public FileArrayAdapter(Context context, int textViewResourceId,
List<Item> objects) {
super(context, textViewResourceId, objects);
c = context;
id = textViewResourceId;
items = objects;
}
public Item getItem(int i)
{
return items.get(i);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater)c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(id, null);
}
/* create a new view of my layout and inflate it in the row */
TextView t1 = (TextView) v.findViewById(R.id.TextView01);
TextView t2 = (TextView) v.findViewById(R.id.TextView02);
TextView t3 = (TextView) v.findViewById(R.id.TextViewDate);
/* Take the ImageView from layout and set the city's image */
ImageView imageCity = (ImageView) v.findViewById(R.id.fd_Icon1);
String uri = "drawable/" + o.getImage();
int imageResource = c.getResources().getIdentifier(uri, null, c.getPackageName());
Drawable image = c.getResources().getDrawable(imageResource);
imageCity.setImageDrawable(image);
if(t1!=null)
t1.setText(o.getName());
if(t2!=null)
t2.setText(o.getData());
if(t3!=null)
t3.setText(o.getDate());
return v;
}
}

Get the position of view in LinearLayout (Android)

A had a custom ListView recently. Then I had to display all the list items without scrollbar. Following the method to place items in LinearLayout I changed my code but I can't bind onClickListener to new layout. In ListView I used position var to determine what view was touched. But in LinearLayout onClick callback hasn't position parameter.
Here is my BasketActivity.class:
package ru.**.**;
public class BasketActivity extends Activity {
ArrayList<Item> items = new ArrayList<Item>();
SQLiteDatabase database;
Map<String, ?> all;
ItemAdapter adapter;
Item item2delete;
View deletingView;
private SharedPreferences settings;
private SharedPreferences settings2;
private Basket basket;
TextView basketSum;
private int position2delete;
private Map<String, ?> all2;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_basket);
<..cutted..>
settings = getSharedPreferences("basket", 0);
settings2 = getSharedPreferences("price", 0);
basket = new Basket(settings, settings2);
all = basket.getList();
LinearLayout l1 = (LinearLayout) findViewById(R.id.l1);
MyDBAdapter myDBAdapter = new MyDBAdapter(getBaseContext());
myDBAdapter.open();
Cursor itemCursor = myDBAdapter.getItemsInBasket(all);
while (itemCursor.moveToNext()) {
String[] columns = itemCursor.getColumnNames();
StringBuilder sb = new StringBuilder();
for (int i = 0; i < columns.length; i++) {
sb.append(columns[i]);
}
Item item = new Item();
item.setId(itemCursor.getString(0));
item.setArticul(itemCursor.getString(MyDBSchema.ITEM_ARTICUL));
item.setTitle(itemCursor.getString(MyDBSchema.ITEM_TITLE));
item.setPrice(itemCursor.getInt(MyDBSchema.ITEM_PRICE));
item.setPic80(itemCursor.getString(MyDBSchema.ITEM_PIC80));
item.setPic300(itemCursor.getString(MyDBSchema.ITEM_PIC300));
item.setMessage(itemCursor.getString(MyDBSchema.ITEM_MESSAGE));
item.setColor(itemCursor.getString(MyDBSchema.ITEM_COLOR));
item.setColorpos(itemCursor.getString(MyDBSchema.ITEM_COLORPOS));
items.add(item);
}
itemCursor.close();
myDBAdapter.close();
for (int position=0; position<items.size(); position++) {
LayoutInflater inflater = getLayoutInflater();
View v = inflater.inflate(R.layout.list_basket, null);
final Item i = items.get(position);
if (i != null) {
Item ei = (Item) i;
final TextView title = (TextView) v.findViewById(R.id.title);
if (title != null) title.setText(ei.title);
final TextView articul = (TextView) v.findViewById(R.id.articul);
if (articul != null) articul.setText(ei.articul);
TextView payed = (TextView) v.findViewById(R.id.payed);
if (payed != null) payed.setVisibility(TextView.GONE);
TextView status = (TextView) v.findViewById(R.id.status);
if (status != null) status.setVisibility(TextView.GONE);
Context context = getBaseContext();
ProgressBar p = new ProgressBar(context);
p.setIndeterminate(true);
Drawable d = p.getIndeterminateDrawable();
WebImageView wiv = (WebImageView) v.findViewById(R.id.pic80);
wiv.setImageWithURL(context, ei.pic80, d);
final TextView price = (TextView) v.findViewById(R.id.price);
if (price != null) price.setText(ei.price_valid);
final TextView quant = (TextView) v.findViewById(R.id.quant);
if (quant != null) {
int q = (Integer) all.get(ei.articul);
if (q > 1) {
quant.setText("x "+q+" шт.");
}
}
}
v.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
deletingView = v;
int position = 0; //The order number of the view should be here!
Item item = (Item) items.get(position);
item2delete = item;
position2delete = position;
AlertDialog.Builder builder = new AlertDialog.Builder(getParent());
builder.setMessage(getString(R.string.suredelete))
.setCancelable(false)
.setPositiveButton(getString(R.string.yes),
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
BasketActivity.this.removeItem();
deletingView.setVisibility(View.GONE);
}
})
.setNegativeButton(getString(R.string.no),
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alert = builder.create();
alert.show();
}
});
l1.addView(v);
}
basketSum = (TextView) findViewById(R.id.basketsum);
basketSum.setText(Html.fromHtml(getString(R.string.basketsum) + ": <b>"
+ basket.getBasketPriceValid() + "</b>"));
}
protected void removeItem() {
basket.remove(item2delete);
Context context = getApplicationContext();
CharSequence text = getText(R.string.item_deleted);
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
basketSum.setText(Html.fromHtml(getString(R.string.basketsum) + ": <b>"
+ basket.getBasketPriceValid() + "</b>"));
items.remove(position2delete);
}
}
My question is how to get view's position at onClick(View v)?

You can use the View's tag;
for (int position=0; position<items.size(); position++) {
v.setTag(position);
}
and in the onClick(View v)
public void onClick(View v) {
int position = 0;
if (v.getTag() instanceof Integer) {
position = (Integer) v.getTag();
}
}

Can you have
v.setTag(items.get(position).getId();
and then in onClick
public void onClick(View v) {
int id= v.getTag();
}
