Problems with OnItemClick on a custom ListView

Problems with OnItemClick on a custom ListView - android

I am using a custom ListView with a custom ArrayAdapter for my custom object. I fill my ListView with parsed data from a xml file. I am able to fill the ListView with these data but I want to switch to different activities depending on which item was clicked. I can show with
int position
which item was clicked but how can I retrieve for example the name of the clicked button?
My code:
/**
* Setup
* */
#SuppressWarnings("unchecked")
private void setup() throws IOException {
device_array = new ArrayList<Device>();
//-----------------ACTIONBAR------------------------------------
//activates the default ActionBar
ActionBar actionBar = getActionBar();
actionBar.show();
// set the app icon as an action to go home
actionBar.setDisplayHomeAsUpEnabled(true);
//-------------------INTENT--------------------------------------
//get data from Intent
Intent intent = getIntent();
Name = intent.getStringExtra("Projectname");
IP = intent.getStringExtra("RouterIP");
URL = intent.getStringExtra("URL");
Port = intent.getStringExtra("Port");
//-------------------TEXTVIEWS+LISTVIEW---------------------------------------
nameproject = (TextView)findViewById(R.id.nameproject);
nameproject.setText("Projektname: "+Name);
routerip = (TextView)findViewById(R.id.routerip);
routerip.setText("KNX/IP-Router-Adresse: "+IP);
port = (TextView)findViewById(R.id.port);
port.setText(":"+Port);
url = (TextView)findViewById(R.id.url);
url.setText("URL: "+URL);
//Fill ListView
display_listview();
devices = (ListView)findViewById(R.id.deviceList);
adapter = new DeviceAdapter(this,
R.layout.listviewitem_device, device_array);
//add a view which is shown if the ListView is empty
devices.setEmptyView(findViewById(R.id.empty_list_view));
//Click on item in listview
devices.setOnItemClickListener(new OnItemClickListener(){
#Override

//------------------ FILL DEVICE ARRAY FROM XML--------------------------------
for (int i=0; i<XML.size(); i++) {
if (XML.get(i).getDptID().contains(ValueTemp)) {
Datapoint d = XML.get(i);
device_array.add(new Device(d.getName().toString(), R.drawable.temperature_5));
Log.d("Temperature", d.getName().toString()+" added");
}
}
for (int i=0; i<XML.size(); i++) {

My Datapoint class:
package XMLParser;
import java.io.Serializable;
public class Datapoint implements Serializable{
/**

private static final long serialVersionUID = 4917183601569112207L;

public Datapoint(){

public String getMainNumber() {
return mainNumber;
}
public void setMainNumber(String mainNumber) {
this.mainNumber = mainNumber;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getStateBased() {
return stateBased;
}
public void setStateBased(String stateBased) {
this.stateBased = stateBased;
}
public String getPriority() {
return priority;
}
public void setPriority(String priority) {
this.priority = priority;
}
public String getGroupadress() {
return groupadress;
}
public void setGroupadress(String group) {
this.groupadress = convert_groupadress(group);
}
public String getDptID() {
return dptID;
}
public void setDptID(String dptID) {
this.dptID = dptID;
}
#Override
public String toString() {
return "[[" + this.stateBased + "] ["+ this.name + "] [" + this.mainNumber + "]" + " [" + this.dptID
+ "] [" + this.priority + "] [" + this.groupadress + " ]]";
}
public String convert_groupadress(String groupadress) {
String groupaddress ="";
int grpadr = Integer.parseInt(groupadress);
int first = grpadr / 2048;
int first_res = grpadr-(first*2048);
int second = first_res / 256;
int second_res = first_res-(second*256);
int third = second_res / 1;
//int third_res = second_res-(third*32);
groupaddress = Integer.toString(first) +"/"+ Integer.toString(second) + "/"+ Integer.toString(third);
return groupaddress;
}
}

Calling the getItem(int position) method on your adapter will get the DataPoint for that position, so change your onItemClick method to be something like:
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
DataPoint point = (DataPoint) parent.getAdapter().getItem(position);
String pointName = point.getName();
// TODO: Launch an activity with that name or something.
}

I solved it this way:
//Click on item in listview
devices.setOnItemClickListener(new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
if(device_array.get(position).getResImage()==R.drawable.brightness){
Intent i0 = new Intent(ProjectView.this, Brightness.class);
i0.putExtra("Uniqid","From_ProjectView_Activity");
i0.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i0);
}
if(device_array.get(position).getResImage()==R.drawable.temperature_5){
Intent i0 = new Intent(ProjectView.this, Temperature.class);
i0.putExtra("Uniqid","From_ProjectView_Activity");
i0.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i0);
}
if(device_array.get(position).getResImage()==R.drawable.lamp){
Intent i0 = new Intent(ProjectView.this, Dimmer.class);
i0.putExtra("Uniqid","From_ProjectView_Activity");
i0.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i0);
}
if(device_array.get(position).getResImage()==R.drawable.lamp_switch){
Intent i0 = new Intent(ProjectView.this, OnOff.class);
i0.putExtra("Uniqid","From_ProjectView_Activity");
i0.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i0);
}
}
});

Use the view , you are using to inflate the data in listview.
as i was using a textview.
here what i used,
TextView tv = (TextView) v.findViewById(R.id.contacts_name);
String savedname = tv.getText().toString();
here v is the argument that we get in the method
public void onItemClick(AdapterView<?> arg0, View v, int position, long arg3)
{ // do something
}

How to get edit text values from a listview

I am not able to get edittext value from dynamic listview. When I am scrolling listview, entered values in edit text is going invisible
Below is My Activity file -
#Override

progressdialog();
if (cd.isConnectingToInternet()) {
getintentData();

}
temstring = temstring.substring(0, temstring.length() - 1);
msgString = msgString + String.format(MAIN_CART, temstring);
Log.e("msgString=============", msgString);
}
This is the method where all the items are adding in the list
public String parseanimcat(String object) {
try {
JSONObject json = new JSONObject(object);
JSONObject jsonobj = json.getJSONObject("data");
status1 = jsonobj.getString("status");
message = jsonobj.getString("message");
arrayList = new ArrayList<>();
JSONArray jarray = jsonobj.getJSONArray("dataFound");
for (int i = 0; i <= jarray.length(); i++) {
JSONObject jobj = jarray.getJSONObject(i);
String category = jobj.getString("category");
String subsubcat_id = jobj.getString("subsubcat_id");
Toast.makeText(ServicHomepage.this, category + "==" + subsubcat_id, Toast.LENGTH_SHORT).show();
model = new Data_Model();
model.setTitle(category);
model.setSubcatid(subsubcat_id);
arrayList.add(model);
}
} catch (JSONException e) {
e.printStackTrace();
}
return object;
}
This is my adapter class-
private class service_list_adapter extends ArrayAdapter<Data_Model>{
private ArrayList<Data_Model> array_list;
Context context;
String[] etValArr;
ViewHolder holder;
String[] totalValue;
Data_Model model;
HashMap<String, String> hm = new HashMap<>();

public service_list_adapter(Context context,int resourceId,ArrayList<Data_Model> arrayList) {
super(context,resourceId,arrayList);
this.context = context;
this.array_list = arrayList;
etValArr = new String[array_list.size()];
totalValue = new String[array_list.size()];
}
private class ViewHolder {
public TextView serv_title;
public EditText serv_descrptn, serv_amount;
}
public View getView(int position, View convertView, ViewGroup parent) {
model = array_list.get(position);
POSITION = position;
LayoutInflater mInflater = (LayoutInflater) context
.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
convertView = mInflater.inflate(R.layout.serv_cat_rowitem, null);

convertView.setTag(holder);
holder.serv_title.setTag(position);
holder.serv_descrptn.setTag(position);
holder.serv_amount.setTag(position);
} else
holder = (ViewHolder) convertView.getTag();
holder.serv_title.setText(model.getTitle());
holder.serv_descrptn.setText(model.getServdescription());
holder.serv_amount.setText(model.getServamount());
holder.serv_amount.addTextChangedListener(new TextWatcher() {
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void afterTextChanged(Editable s) {
model.setServamount(s.toString());
}
});
holder.serv_descrptn.addTextChangedListener(new TextWatcher() {
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void afterTextChanged(Editable s) {
model.setServdescription(s.toString());
}
});
return convertView;
}
}

be more specific exactly which editText value you want.
you can implement onScrollListner on list and save the value of the editText on that event and later use it

Dynamic ListView scroll TextView changed automatically

when i click + button increment the price and click - button decrease the price it's work perfectly but when i scroll listview the value of tvPrices (TextView) is changed.
What should i do for the stay increment price?
here is my adapter

*/

}

In onclick, after you decrement the value call notifyDataSetChanged()
notifyDataSetChanged
but its a costly operation, since it refreshes complete list

Not able to see files while opening file browser using AndroidFileBrowser Library

I am trying to make a File browser for which I am taking help of this library.
Now according their code I am trying to implement, it's opening the desired location in the cell, however I am only able to see directories not files. As instructed I have chosen the option to choose Files only still I am not able to see Files there. Below is the code I am using
Intent fileExploreIntent = new Intent(FileBrowserActivity.INTENT_ACTION_SELECT_DIR,
null, getActivity(), FileBrowserActivity.class
);
startActivityForResult(fileExploreIntent,1);
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
if (requestCode == 1) {
if(resultCode == getActivity().RESULT_OK) {
String newDir = data.getStringExtra(FileBrowserActivity.returnDirectoryParameter);
Toast.makeText( getActivity(), "Received path from file browser:"+newDir, Toast.LENGTH_LONG).show();
} else {//if(resultCode == this.RESULT_OK) {
Toast.makeText( getActivity(),"Received NO result from file browser",Toast.LENGTH_LONG).show();
}//END } else {//if(resultCode == this.RESULT_OK) {

How can I proceed in these two scenarios?
EventParsingClass EPSP= ??? and
EPSP.getid= ??

fetch[0]="XXX"
fetch[1]="YYY"
fetch[2]="ZZZ"
lv.setOnItemClickListener(MainActivity.this);
public void onItemClick(AdapterView<?> parent, View view, int position,long id)
Toast.makeText(getApplicationContext(), fetch[position] + "Clicked",
Toast.LENGTH_LONG).show();
}
just declare fetch[position] to get the value of clicked item. hope this will give you some solution.

Use int position to find out values from your data list (array list or what ever you used).
lv.setOnItemClickListener(MainActivity.this);
public void onItemClick(AdapterView<?> parent, View view, int position,long id)
Toast.makeText(getApplicationContext(), EPSP.getid(position) + "Clicked",Toast.LENGTH_LONG).show();
}

EventItem item = (EventItem) parent.getItemAtPosition(position);
Now you have a hold of EventItem. So you can start using the get methods of your EventItem class in order to get whatever you want from it.

I got the solution:
EventParsingClass new_method(int value) {
int item_count = 0;
for (int i = 0; i < arrayOfEventDescription.size(); i++) {
ArrayList<EventParsingClass> Arraylist_for_loop = arrayOfEventDescription
.get(i);
item_count++;
for (int j = 0; j < Arraylist_for_loop.size(); j++) {
if (value == item_count) {
return Arraylist_for_loop.get(j);
}
item_count++;
}
}
return null;
}
And call it from here:
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
EventParsingClass newObject = new_method(arg2);
if (newObject == null) {
} else {
Log.d("Generated Value Id : ", "" + newObject.getId());
Toast.makeText(getApplicationContext(),
"Item Clicked" + arg2 + "-----" + newObject.getTitle(),
Toast.LENGTH_LONG).show();
}
}

Check/Uncheck all the CheckedTextView in a ListView custom adapter

I have such a custom adapter:
adapter = new ArrayAdapter<Item>(this,
R.layout.file_manager, R.id.checkedTextItem,
fileList)
{
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// creates view
LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.item, null);
view.setFocusable(false);
CheckedTextView textView = (CheckedTextView) view
.findViewById(R.id.checkedTextItem);
// put the image on the text view
textView.setCompoundDrawablesWithIntrinsicBounds(
fileList[position].icon, 0, 0, 0);
textView.setTextColor(Color.WHITE);
textView.setText(fileList[position].file);
if(fileList[position].file.equalsIgnoreCase("select all") & (fileList[position].check == true))
{
for(int i =0;i<fileList.length;i++)
{
fileList[i].setItemCheck(true);
chosenFile = fileList[i].file;
File sel = new File(path + "/" + chosenFile);
if (sel.isFile())
resFiles.add(sel);
}
resFiles.remove(position);
}
else if(fileList[position].file.equalsIgnoreCase("select all") & (fileList[position].check == false))
{
{
for(int i =0;i<fileList.length;i++)
{
fileList[i].setItemCheck(false);
}
}
}
if(fileList[position].icon == R.drawable.directory_icon)
textView.setCheckMarkDrawable(null);
else if(fileList[position].icon == R.drawable.directory_up)
textView.setCheckMarkDrawable(null);
if(fileList[position].check == true)
textView.setChecked(true);
else
textView.setChecked(false);
// add margin between image and text (support various screen
// densities)
int dp5 = (int) (5 * getResources().getDisplayMetrics().density + 0.5f);
textView.setCompoundDrawablePadding(dp5);
textView.setFocusable(false);
return view;
}
};
I have a class Item, where I created boolean field check:+
public class Item {
public String file;
public int icon;
public boolean check;
public Item(String file, Integer icon, boolean check) {
this.file = file;
this.icon = icon;
this.check = check;
}
public String getItemFile()
{
return file;
}
public int getItemIcon()
{
return icon;
}
public boolean getItemCheck()
{
return check;
}
public void setItemCheck(boolean check)
{
this.check = check;
}
public void setItemFile(String file)
{
this.file = file;
}
public void setItemIcon(int icon)
{
this.icon = icon;
}
public void toggle()
{
check = !check;
}
#Override
public String toString() {
return file + " "+ icon+ " "+ check;
}
}
And my listView setOnItemClickListener where I set the check state of the item, which was clicked with the toggle() method of the Item class
lv.setOnItemClickListener(new android.widget.AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> myAdapter, View myView, int myItemInt, long mylng)
{
//String selectedFromList = (lv.getItemAtPosition(myItemInt).toString());
myView.setFocusable(false);
chosenFile = fileList[myItemInt].file;
File sel = new File(path + "/" + chosenFile);
Log.i("path",sel.toString());
if (sel.isDirectory()) {
firstLvl = false;
str.add(chosenFile);
fileList = null;
path = new File(sel + "");
loadFileList();
lv.setAdapter(adapter);
}
else if (chosenFile.equalsIgnoreCase("up") && !sel.exists()) {
// present directory removed from list
String s = str.remove(str.size() - 1);
// path modified to exclude present directory
path = new File(path.toString().substring(0,
path.toString().lastIndexOf(s)));
fileList = null;
// if there are no more directories in the list, then
// its the first level
if (str.isEmpty()) {
firstLvl = true;
}
loadFileList();
lv.setAdapter(adapter);
}
else
{
fileList[myItemInt].toggle();
if (fileList[myItemInt].check == true)
resFiles.add(sel);
else
resFiles.remove(sel);
adapter.notifyDataSetChanged();
Log.i(fileList[myItemInt].file,Boolean.toString(fileList[myItemInt].check));
}
}
});
I want to implement ability to check all the CheckedTextView. I try to do it in my getView() method of the adapter. I can check all the items, but problem is in uncheck. Because when I call fileList[i].setItemCheck(false); at the statement when check state of 'select all' item is false I can't check all the items by clicking. How can I implement this in some better way?

I solved it by changing the setOnItemClickListener method. The problem was is that I tried to check all the items in my loadFileList() method, which determines all the checkable state, but I should handle single checking and all checking in different parts of code. Now I do it in else statement of setOnItemClickListener...It looks like this:
else
{
fileList[myItemInt].toggle();
if(fileList[myItemInt].file.equalsIgnoreCase("select all") & (fileList[myItemInt].check == true))
{
String selectAllFile = fileList[myItemInt].file;
File all = new File(path + "/" + selectAllFile);
for(int i =0;i<fileList.length;i++)
{
chosenFile = fileList[i].file;
File select = new File(path + "/" + chosenFile);
fileList[i].setItemCheck(true);
if (select.isFile())
{
resFiles.add(select);
resFiles.remove(all);
}
}
adapter.notifyDataSetChanged();
}
else if(fileList[myItemInt].file.equalsIgnoreCase("select all") & (fileList[myItemInt].check == false))
{
for(int i =0;i<fileList.length;i++)
{
fileList[i].setItemCheck(false);
}
adapter.notifyDataSetChanged();
}
if (fileList[myItemInt].check == true)
{
resFiles.add(sel);
if(fileList[myItemInt].file.equalsIgnoreCase("select all"))
{
String selectAllFile = fileList[myItemInt].file;
File all = new File(path + "/" + selectAllFile);
resFiles.remove(all);
}
}
else
resFiles.remove(sel);
adapter.notifyDataSetChanged();
Log.i(fileList[myItemInt].file,Boolean.toString(fileList[myItemInt].check));
}
}
});
