I have wasted a lot of time finding the problem but i cannnot understand why it is not showing on the screen. please guide me.

Correct in your code as below:
#Override
public Object getItem(int arg0) {
return planArraylist.get(planArraylist.get(arg0-1)); }
#Override
public long getItemId(int arg0) {
return arg0; }

I think you write you getView method differently and use a holder class, as shown below:
#Override
public Object getItem(int arg0) {
return planArraylist.get(arg0);
}
#Override
public long getItemId(int arg0) {
return arg0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = layoutInflater.inflate(R.layout.single_lv_item, parent, false);
holder = new ViewHolder();
holder.tvdrCode = (TextView) convertView.findViewById(R.id.dcode);
holder.tvDrName = (TextView) convertView.findViewById(R.id.dname);
holder.tvTerr = (TextView) convertView.findViewById(R.id.tcode);
holder.tvAdr = (TextView) convertView.findViewById(R.id.a);
holder.tvClassDesc = (TextView) convertView.findViewById(R.id.cd);
holder.tvShift = (TextView) convertView.findViewById(R.id.tvshift);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
Planning p = planArraylist.get(position);
holder.tvdrCode.setText(p.getDrCode());
holder.tvDrName.setText(p.getDocName());
holder.tvTerr.setText(p.getTerrCode());
holder.tvAdr.setText(p.getAdr());
holder.tvClassDesc.setText(p.getClassDesc());
holder.tvShift.setText(p.getShift());
return convertView;
}
static class ViewHolder {
TextView tvdrCode;
TextView tvDrName;
TextView tvTerr;
TextView tvAdr;
TextView tvClassDesc;
TextView tvShift;
}
Also, your list view xml file uses a Linear layout but you have properties that can only be found in a Relative layout such as android:layout_alignParentTop="true". Could you fix that as well?

if you still happy with ListView then you can take idea from below
code
here i am using Cursor but you can use ArrayList in place of Cursor
public class Custom_Adapter_Products extends BaseAdapter {
Context context;
Cursor mCursor;
static int[] intArr;
DatabaseAdapter db;
public ImageLoader imageLoader;
public Custom_Adapter_Products(Context context, Cursor mCursor){
this.context = context;
this.mCursor = mCursor;
this.intArr = new int[this.mCursor.getCount()];
imageLoader=new ImageLoader(context);
}
#Override
public int getCount() {
return mCursor.getCount();
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
try{
ViewHolder holder;
this.mCursor.moveToPosition(position);
LayoutInflater vi = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
{
convertView = vi.inflate(R.layout.lv_row_for_products, null);
holder = createViewHolder(convertView);
convertView.setTag(holder);
holder.btnMinus.setTag(holder);
holder.btnAdd.setTag(holder);
}
else
{
holder = (ViewHolder) convertView.getTag();
}
holder.btnMinus.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
try{
ViewHolder holder = (ViewHolder) v.getTag();
// Do whatever you want
}catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
}
});
}catch (Exception e){
// TODO: handle exception
e.printStackTrace();
}
return convertView;
}
private static class ViewHolder
{
public TextView tvProductName;
public TextView tvPrice;
public TextView tvMRP;
public TextView tvMOQ;
public TextView tvPercent;
public TextView tvQuantity;
public ImageView imgProduct;
public ProgressBar pBar;
public Button btnMinus;
public Button btnAdd;
}
private ViewHolder createViewHolder(View v) {
ViewHolder holder = new ViewHolder();
try{

Use an AlarmManager with your specified time and the moment alarm will trigger you can enable the button, hence enabling the click event for the button.
Edit:
Either you can go ahead with handler object and use handler.postDelayed() method or there itself you can create a Timer Object and schedule the timer task within that object and do the stuff.

Assuming that u know how to convert the time strings into timestamps,modify ur adapter like this:
public class Custom extends BaseAdapter {
Activity a;
ArrayList<Model> data;
public Custom(Activity a, ArrayList<Model> data) {
this.a = a;
this.data = data;
}
#Override
public int getCount() {
return data.size();
}
#Override
public Object getItem(int i) {
return data.get(i);
}
#Override
public long getItemId(int i) {
return i;
}
public class Viewholder {
TextView srno, name, intime;
Button end;
}
#Override
public View getView(final int i, View convertView, ViewGroup viewGroup) {
Viewholder viewholder = null;
if (convertView == null) {
viewholder = new Viewholder();
LayoutInflater li = a.getLayoutInflater();
convertView = li.inflate(R.layout.list_item, viewGroup, false);
viewholder.srno = (TextView) convertView.findViewById(R.id.cno);
viewholder.name = (TextView) convertView.findViewById(R.id.cname);
viewholder.intime = (TextView) convertView.findViewById(R.id.ctime);
viewholder.end = (Button) convertView.findViewById(R.id.cend);
convertView.setTag(viewholder);
}else {
viewholder=(Viewholder)convertView.getTag();
}
final Model model = data.get(i);
viewholder.srno.setText(valueOf(data.get(i).getNo()));
viewholder.name.setText(valueOf(data.get(i).getName()));
viewholder.intime.setText(valueOf(data.get(i).getIntime()));
final Runnable r = new Runnable() {
public void run() {
viewholder.end.setEnabled(true);
}
};
if(yourObjectTimestamp - currentTimeStamp > 20){ //this u need to do on ur own
viewholder.end.setEnabled(true); // I assumed u know how to convert times to timestamps
}else{
viewholder.end.setEnabled(false);
long timeDiffInMillis = yourObjectTimestamp - currentTimeStamp;
handler.postDelayed(r,timeDiffInMillis );
}
viewholder.end.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(a, data.get(i).getName()+" Exited", Toast.LENGTH_LONG).show();

How to get id of particular item of listview in android?

I am using Listview and set the multiple item and each item have Like, share and comment option.
Actually I have fetch the Item Id and also setText of TextView, Its Successfully. But Not able to get Item Id on Like Button Click event for particular item.
How to fetch Item Id for every items in Listview on Button Click Event?
Demo for MyAdapter Class:

Try with below code:
public class Adapter1 extends BaseAdapter implements OnClickListener {
public ArrayList<HashMap<String, String>> arr = null;
Context context = null;
LayoutInflater layoutInflater = null;
HashMap<String, String> getData = new HashMap<String, String>();
String urlLike = null;
TextView strId = null;
public NewsFeedAdapter(Context context,
ArrayList<HashMap<String, String>> arr) {
this.context = context;
this.arr= arr;
layoutInflater = LayoutInflater.from(context);
}
#Override
public int getCount() {
return arr.size();
}
#Override
public Object getItem(int position) {
return arr.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder = null;
if (convertView == null) {
convertView = layoutInflater.inflate(
R.layout.my_list_item, null);
/** initialize ViewHolder */
viewHolder = new ViewHolder();
/** Initialize Widgets */
/** Imageview */
viewHolder.imgLike = (ImageView) convertView
.findViewById(R.id.imgLike);
viewHolder.imgComments = (ImageView) convertView
.findViewById(R.id.imgComments);
viewHolder.imgComments.setOnClickListener(this);
viewHolder.imgShare = (ImageView) convertView
.findViewById(R.id.imgShare);
viewHolder.imgShare.setOnClickListener(this);
/** TextView */
viewHolder.txtId = (TextView) convertView
.findViewById(R.id.txtId);
viewHolder.txtDescription = (TextView) convertView
.findViewById(R.id.txtDescription);
getData = arr.get(position);
viewHolder.txtId.setText(getData
.get(Fragment1.TAG_ID));
viewHolder.txtDescription.setText(getData
.get(Fragment1.TAG_MESSAGE));
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
convertView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
}
});
viewHolder.imgLike.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
strId=arr.get(position).getId();//or whatever you want to do do here.
}
});
return convertView;
}
/** ViewHolder Class */
public class ViewHolder {
ImageView imgLike = null, imgComments = null,
imgShare = null;
TextView txtId = null,txtDescription = null;
}
}

Try this:
strId = (TextView) view.getParent().findViewById(R.id.txtId);
This will fix your crash, but you need to rethink about your design.

What u have to do is set Diff onclick Listeners on diff views
viewHolder.txtDescription.setTag(R.id.txtDescription,position);
viewHolder.txtDescription.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
int position_clicked=(Integer)v.getTag();
}
});
repeat it for every view your want to set listener

You need to initialize strId in getView()
here in the following code, its not able to initialize it based on "view" object, hence you get nullpointer.
case R.id.imgLike:
strId = ((TextView) view.findViewById(R.id.txtId));
mark as solved if you find the answer useful.

You can also use onClickListener inside your adapter class.
Look this sample code
viewHolder.imgLike = (ImageView) convertView.findViewById(R.id.imgLike);
viewHolder.imgLike.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
String id = getData.get(Fragment1.TAG_ID);
}
});

try like this,
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder = null;
if (convertView == null) {
convertView = layoutInflater.inflate(
R.layout.my_list_item, null);
/** initialize ViewHolder */
viewHolder = new ViewHolder();
/** Initialize Widgets */
/** Imageview */
viewHolder.imgLike = (ImageView) convertView
.findViewById(R.id.imgLike);
viewHolder.imgLike.setOnClickListener(this);
viewHolder.imgLike.setTag(position);
viewHolder.imgComments = (ImageView) convertView
.findViewById(R.id.imgComments);
viewHolder.imgComments.setOnClickListener(this);
viewHolder.imgShare = (ImageView) convertView
.findViewById(R.id.imgShare);
viewHolder.imgShare.setOnClickListener(this);
/** TextView */
viewHolder.txtId = (TextView) convertView
.findViewById(R.id.txtId);
viewHolder.txtDescription = (TextView) convertView
.findViewById(R.id.txtDescription);
getData = arr.get(position);
viewHolder.txtId.setText(getData
.get(Fragment1.TAG_ID));
viewHolder.txtDescription.setText(getData
.get(Fragment1.TAG_MESSAGE));
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
convertView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
}
});
return convertView;
}
#Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.imgLike:
View view = listview.getAdapter().getView(((ImageView)v).getTag(), null, listview);
txtId = (TextView) view.findViewById(R.id.txtId);
System.out.println("On Click====="
+ strId.getText().toString());
urlLike = "http://www.example.com?id="
+ strId.getText().toString() + "&user_id="
+ myDetail.getUserId();
new sendLikeData().execute();
break;
case R.id.imgComments:
break;
case R.id.imgShare:
break;
default:
break;
}
}

Adding radio button to listview

return price;
}
public void setPrice(String price) {
this.price = price;
}
public int getImageNumber() {

I have seen many SO anwsers but none of them got working in my case saying to add
listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
Can anyone say me how to acheive this ?

For complex ListView item, you should do it by yourself. Just add boolean isSelected in your ItemDetails and then checkBox.setChecked(item.isSelected); in your getView() in ItemListBaseAdapter. Now when an item is clicked in ListView just change your the data in itemDetailsrrayList and call notifyDataSetChanged().

I have made my getView() method.Just make radio button instead of simple button.I Hope this helps.
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View productListView = null;
productListView = convertView;
LayoutInflater inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (productListView == null)
productListView = inflater.inflate(R.layout.menu_productlist_list,
parent, false);
productListTitle = (TextView) productListView
.findViewById(R.id.productListTitle);
String title = menuProductListCollection.get(position).getPD_TITLE();
productListTitle.setText(title);
productListCategoryButton = (ImageButton) productListView
.findViewById(R.id.productListCategoryButton);
// Perform Button action on click of each row's button
productListCategoryButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
//do your stuff here
}
});
// Perform action on click of each row
productListView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
//do your stuff here
}
});
return productListView;
}

I think you should try both of this,
listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
And in xml file you need to add,
<ListView
...
android:choiceMode="singleChoice"
... />
Also add this in your radio-button's xml,
<RadioButton
...
android:clickable="false"
android:focusable="false"
... />
Make HashMap m and initialize it
for (HashMap<String, Object> m :list_data) //make data of this view should not be null (hide )
m.put("checked", false);
Now, setViewBinder to adapter
adapter.setViewBinder(new SimpleAdapter.ViewBinder()
{
public boolean setViewValue(View view, Object data, String textRepresentation)
{
if (data == null) //if 2nd line text is null, its textview should be hidden
{
view.setVisibility(View.GONE);
return true;
}
view.setVisibility(View.VISIBLE);
return false;
}
});
It will work like charm.
