Click Listener + Checkbox - On Android

public class ChooseFavorites extends Activity implements OnItemClickListener { StationManager st; MyCustomAdapter arr; ListView list; @Override protected vo

Solution 1:

You can use this event to get notified about the checkbox being checked/unchecked

cb.setOnCheckedChangeListener(newCompoundButton.OnCheckedChangeListener() {

   @OverridepublicvoidonCheckedChanged(CompoundButton buttonView,boolean isChecked) {

   }
}

Solution 2:

Use Checkbox setOnCheckedChangeListener event.

Try like this...

CheckBoxChkBx= ( CheckBox ) findViewById( R.id.checkbox);
ChkBx.setOnCheckedChangeListener(newOnCheckedChangeListener()
{
  publicvoidonCheckedChanged(CompoundButton buttonView, boolean isChecked)
  {
    if ( isChecked )
    {
        // perform logic
    }

  }
});

Solution 3:

You can use following:

listView.setOnItemClickListener(newOnItemClickListener() {
    @OverridepublicvoidonItemClick(AdapterView<?> parent, View view,
        int position, long id) {
        Toast.makeText(getApplicationContext(), 
                       "Click ListItem Number " + position, Toast.LENGTH_LONG)
                      .show();
    }
}); 

Or u can save position as tag to checkbox and check on checkbox clicklistener

@Overridepublic View getView(int position, View convertView, ViewGroup parent)
        {
//            ur code...

 **cb.setTag(position);**
            row.setOnClickListener(this);
            return row;
        }


        @OverridepublicvoidonClick(View v) {
            // TODO Auto-generated method stub
**intposition= v.getTag();** //cast & check for Tag not null too.Toasttoast= Toast.makeText(getApplicationContext(), "", Toast.LENGTH_SHORT);
            toast.show();


        }

Solution 4:

@Overridepublic View getView(finalint position, View convertView, ViewGroup parent)
    {
        // TODO Auto-generated method stubViewrow= convertView;
        if(row==null)
        { // Object reuse
            inflater = getLayoutInflater();
            row = inflater.inflate(R.layout.favorite_row, parent, false);
        }
        stationName1 = (TextView)row.findViewById(R.id.textFavoriteItemInRow);
        stationName1.setText(stationNames[position]);
        cb=(CheckBox)row.findViewById(R.id.cbCheck);

        cb.setOnCheckedChangeListener(newCompoundButton.
                OnCheckedChangeListener(){
               @OverridepublicvoidonCheckedChanged(CompoundButton buttonView,boolean isChecked) {
                   if (isChecked)
                   {
                       cb.setChecked(isChecked);
                        Toasttoast= Toast.makeText(getApplicationContext(), "checked" + position, Toast.LENGTH_SHORT);
                        toast.show();
                   }
                   else
                   {
                       cb.setChecked(isChecked);
                        Toasttoast= Toast.makeText(getApplicationContext(), "unChecked" + position, Toast.LENGTH_SHORT);
                        toast.show();
                   }
               }
            });

        return row;
    }

}

     // Create a view for it

     });
  }
  else{
     // In order to reuse the preallocated memory, get the holder from View's tag, // which is allocated and saved in this view object. When a view requests // to be rendered and it has not been instantiated, we new a holder and save// it to View's 'Tag' for later reuse.
     holder = (viewHolder) convertView.getTag();

        }

  }

  //+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++// Set checkbox state with calling the method getSelectedState which // provied by your own class.
  holder.checkBox.setChecked(itemsList.get(position).getSelectedState());
