Hai i'm trying to develop an app where by i can send sms and email to a particular group of people..I have a listview showing the contacts which are in my group.Each row is of the formTextView(Name)TextView(phone) Checkbox(sms)TextView(email id) Checkbox(mail)I have used custom adapter to display the contact details to the listview.ihave set the onitemclick listener to find the position of the row..I have to send sms and email to those contacts for which checkboxes have been set as true.how can i find the state of each of the checkboxes.Please help me..lotz of thanx in advance..I hav added below the custom adapetr i hv created..public class ContactInfoAdapter extends ArrayAdapter{private ArrayList<Boolean> mChecked_sms,mChecked_email;Context context;int layoutResourceId;ContactInfo data[] = null;public ContactInfoAdapter(Context context, int layoutResourceId, ContactInfo[] data) { super(context, layoutResourceId, data); this.layoutResourceId = layoutResourceId; this.context = context; this.data = data; mChecked_sms = new ArrayList<Boolean>(); mChecked_email = new ArrayList<Boolean>(); for (int i = 0; i < this.getCount(); i++) { mChecked_sms.add(i, false); mChecked_email.add(i,false); }}@Overridepublic View getView(final int position, View convertView, ViewGroup parent) { final ContactHolder holder; View row = convertView; if(row == null) { LayoutInflater inflater = ((Activity)context).getLayoutInflater(); row = inflater.inflate(layoutResourceId, parent, false); holder = new ContactHolder(); holder.txtName = (TextView)row.findViewById(R.id.textViewName); holder.txtPhone = (TextView) row.findViewById(R.id.textViewPhone); holder.txtEmail = (TextView) row.findViewById(R.id.textViewEmail); holder.cb_sms_state = (CheckBox) row.findViewById(R.id.checkBox1); holder.cb_email_state = (CheckBox) row.findViewById(R.id.checkBox2); row.setTag(holder); } else { holder = (ContactHolder)row.getTag(); } ContactInfo contact = data[position]; holder.txtName.setText(contact.name); holder.cb_sms_state.setOnClickListener(new OnClickListener() { public void onClick(View v) { if (holder.cb_sms_state.isChecked()) { mChecked_sms.set(position, true); Toast.makeText(getContext(), "checked", 2).show(); } else { mChecked_sms.set(position, false); } } }); holder.cb_sms_state.setChecked(mChecked_sms.get(position)); holder.cb_email_state.setOnClickListener(new OnClickListener() { public void onClick(View v) { if (holder.cb_email_state.isChecked()) { mChecked_email.set(position, true); Toast.makeText(getContext(), "checked", 2).show(); } else { mChecked_email.set(position, false); } } }); holder.cb_email_state.setChecked(mChecked_email.get(position)); holder.txtPhone.setText(contact.number); holder.txtEmail.setText(contact.email); return row;}static class ContactHolder{ TextView txtName; TextView txtPhone; TextView txtEmail; CheckBox cb_sms_state; CheckBox cb_email_state;}}The ContactInfo class is :public class ContactInfo {public String name;public String number;public String email;public boolean sms_state;public boolean email_state;public ContactInfo(){ super();}public ContactInfo(String name,String number,String email,boolean sms_state,boolean email_state) { super(); this.name = name; this.number = number; this.email = email; this.sms_state = sms_state; this.email_state = email_state;}public void setName(String name) { this.name = name;}public String getName() { return name;}public void setNUmber(String number) { this.number = number;}public String getNumber() { return number;}public void setEmail(String email) { this.email = email;}public String getEmail() { return email;}public void setSms_state(Boolean sms_state){ this.sms_state = sms_state;}public Boolean getSms_state(){ return sms_state;}public void setEmail_state(Boolean email_state){ this.email_state = email_state;}public Boolean getEmail_state(){ return email_state;} 解决方案 Inside the getView() method, you have to implement a OnCheckedChangeListener for the CheckBox.Here is a listener code, say for example:ChkBx.setOnCheckedChangeListener(new OnCheckedChangeListener(){ public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { if ( isChecked ) { // perform logic } }});
