Android Custom Listview

Question

Hi

I have created custom listview which contain Imageview+TextView+Checkbox Now my problem is that i have to get which row's check box is checked.

Xml row.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout android:id="@+id/LinearLayout01"
    android:orientation="horizontal" android:layout_width="fill_parent"
    android:gravity="center_vertical" android:layout_height="60dip">

    <LinearLayout android:id="@+id/LinearLayout03"
        android:orientation="vertical" android:gravity="center_vertical"
        android:layout_marginLeft="10dip" android:layout_height="60dip"
        android:layout_width="260dip">

        <TextView android:id="@+id/desc" android:layout_width="fill_parent"
            android:layout_height="40dip" android:ellipsize="marquee"
            android:text="Text" android:textSize="20dip" android:textStyle="bold"
            android:gravity="center_vertical" android:textColor="@color/black" />
        <TextView android:layout_width="wrap_content"
            android:layout_height="wrap_content" android:text="Phone number"
            android:id="@+id/phone_no" android:textColor="@color/black"></TextView>

    </LinearLayout>
    <LinearLayout android:id="@+id/LinearLayout02"
        android:layout_width="fill_parent" android:gravity="center_vertical"
        android:layout_height="60dip">

        <CheckBox android:layout_width="wrap_content"
            android:layout_height="wrap_content" android:id="@+id/chk_number"></CheckBox>
    </LinearLayout>
</LinearLayout>

and Adapter is:

class ContactList extends ArrayAdapter{

    Activity context;
    public ContactList(Activity context) {
        super(context, R.layout.row,names);
        this.context = context;
    }

public View getView(int position, View convertView, ViewGroup parent) {
    LayoutInflater inflater = context.getLayoutInflater();
    View row = inflater.inflate(R.layout.row, null);

    TextView Name = (TextView) row.findViewById(R.id.desc);
    TextView Number = (TextView) row.findViewById(R.id.phone_no);
    Name.setText(names.get(position));
    Number.setText(numbers.get(position));

    CheckBox checkboxnumberScramble = (CheckBox) row.findViewWithTag(R.id.chk_number);
    checkboxnumberScramble.setChecked(true);
    checkboxnumberScramble.setOnCheckedChangeListener(new OnCheckedChangeListener() {
        public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {

            if (isChecked) { 
                setCheckboxflag(true);
            }else{
                setCheckboxflag(false);
            }
         }
    });

    return (row);
    }
}

I get exception on onCreate of my Activity .

Answer 1

you have to use OnItemClickListner interface to check which list item is selected.

like:

class youractivity extends Activity implements OnItemClickLister

and set the listener to ur listview

listview_object.setOnItemClicklistener(this);

override the OnItemClick method like:

@Override

OnItemClick(){ //what you want to do? that is here }

thats all.
