Check box sending value to next activity even after deselcting it

Check box sending value to next activity even after deselcting it - android

I used a listview to display the check boxes in my activity. I also put a check to see atleast one check box is checked otherwise it will toast a message asking the user to please select atleast one value. Below are my two classes. Problem which i am having is that when i press the submit button without selecting a check box then i get a message to select atleast one checkbox. But when i select and deselect the check box and then submit it then it goes to the next activity with value of the check box which i dont want. It should not go to the other activity till i select one checkbox. Please help me with this problem.

You can put all the checkboxes in a Collection of checkboxes.
Upon clicking submit button, loop through all checkboxes to see anyone of them is checked at that moment
Collection<CheckBox> boxes=new Vector<CheckBox>();
...
public void onClick(View v){
boolean anyoneChecked=false;
for(CheckBox b: boxes){
if(b.isChecked()){
anyoneChecked=true;
}
}
if(!anyoneChecked){
return;
}
// go to next activity
}

You can use onRestart , which will be triggered when existing activity will be bought back to front .
As quoted in docs
Called after onStop() when the current activity is being re-displayed
to the user (the user has navigated back to it). It will be followed
by onStart() and then onResume().
so Override onRestart
#Override
public void onRestart() {
// you come back to me
}

In adapter I did code for counter in btnplus click event.I want to set qty 1 in each row in textview txtqty and in each row increment start from 1 and according to quantity I will get total but if in first row i set qty 5 with increment from plus button in next it start from 6 but I want it start from 1 same as first row how I resolve it?

This is a lot ta code dude...
I Wonder why your Productlistadapter object needs two contexts and why you give the first context as Item activity.this but nevertheless
One big Problem here is that you are trying to make a network connection on the main thread...that's an error when you are in strict mode while debugging...

This might not be the correct approach of coding ,where in you have all the asyncs in one activity.
But to achieve what you want you can use the context that you pass in the adapter like this:
((YourActivityYouArePassing)mContext).someMethod();
the activity's context must be the same as the one you are using for type casting, and someMethod() should be a method declared inside the activity with public keyword.
in someMethod() you could then call your async task like:
public void someMethod() {
new AsyncClass().execute();
}
EDIT:
The onClick will look like this in the adapter
localViewholder.quote.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
/*
* HERE I WANT TO CALL "GETqUOTElIST" ASYNCTASK OF MY ACTIVITY/////!!!!!!!
*/
((YourActivityYouArePassing)mContext).someMethod();
}
});
Hope that helps!!

You can call async task on text click inside Custom adapter
localViewholder.quote.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
new GetBuyingReqList.execute();
}
});
and make GetBuyingReqList class private to public

put below code where u want
GetBuyingReqList getBuyingReqList = new GetBuyingReqList ();
getBuyingReqList .execute();

Possible duplicate How to Call AsyncTask from Adapter class?
found these answers
move your adapter class inside your activity class and make adapter class as inner class.so you have access for calling Asynctask in adapter
Remove AsyncTask Inner class from activity class and Make AsyncTask as a separate class (put it in your package). After that you can call like this "new Asynctask().execute();" from any where
what i did... i sent an instance of the activity to the adapter while initializing, then i called a method at the activity by activity.method() and this method calls the AsyncTask

return paramView;
}
static class Viewholder {
private TextView categoryName;
}
}

I changed your code , try this now
public class CategoryAdapter extends BaseAdapter {
private ArrayList<String> categoryArray;
private Context mContext;
private Viewholder localViewholder = null;
public CategoryAdapter(Context paramContext,
ArrayList<String> paramArrayList) {
this.mContext = paramContext;
this.categoryArray = paramArrayList;
}
public int getCount() {
return this.categoryArray.size();
}
public void setAllItems(ArrayList<String> paramArrayList) {
this.categoryArray.addAll(paramArrayList);
}
public Object getItem(int paramInt) {
return Integer.valueOf(paramInt);
}
public long getItemId(int paramInt) {
return paramInt;
}
public View getView(int paramInt, View paramView, ViewGroup paramViewGroup) {
LayoutInflater localLayoutInflater = (LayoutInflater) this.mContext
.getSystemService("layout_inflater");
if (paramView == null) {
localViewholder = new Viewholder();
paramView = localLayoutInflater.inflate(R.layout.list_item,
paramViewGroup, false);
localViewholder = new Viewholder();
localViewholder.categoryName = ((TextView) paramView
.findViewById(R.id.name));
paramView.setTag(localViewholder);
} else {
localViewholder = (Viewholder) paramView.getTag();
}
localViewholder.categoryName.setText(categoryArray.get(paramInt)
.indexOf(0));
return paramView;
}
static class Viewholder {
private TextView categoryName;
}
}
