具有自定义列表视图的复选框

Question

I am using cursoradapter to get the values from database and to display it in listview.I am able to show the database contents in listview also onclick of perticular item I am getting value of clicked Item.Now I want checkbox also so that oncheck I should get the values of checked Items ( In this case both checkbox click and listitemclick both should work) is it possible? how to do it?

private void displayListView() {
        final Cursor cursor = dbHelper.fetchAllRecords();
        String[] columns = new String[] {
                RecordsDbAdapter.KEY_NAME,
                RecordsDbAdapter.KEY_BIRTHDAY,

        };
        int[] to = new int[] {
                R.id.name,
                R.id.birthdate,
        };
        dataAdapter = new SimpleCursorAdapter(
                this, R.layout.rownew,
                cursor,
                columns,    
                to);
        View v = getLayoutInflater().inflate(R.layout.customdialog, null);
        ListView listView = (ListView) v.findViewById(R.id.listChildren);
        final EditText etChild = (EditText) v.findViewById(R.id.etChild);
        listView.setAdapter(dataAdapter);
        listView.setOnItemClickListener(new OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
                name = ((TextView) view.findViewById(R.id.name)) .getText().toString();
                BirtDate = ((TextView) view.findViewById(R.id.birthdate)) .getText().toString();
                Log.d("*************", name);

                Info=name+ " " +BirtDate;
                Log.d("nameeeeeeeeeeeeeeee",Info);
                etChild.setText(new StringBuilder().append(Info));
                topaste=etChild.getText().toString();
                    etChild.setText(new StringBuilder().append(Info1));
                //                  topaste1=etChild.getText().toString();
                //              }


            }
        })

You could extend SimpleCursorAdapter to add a click listener for your checkbox. Here is a snippet of the code I use:

public class MultiSelectCursorAdapter extends SimpleCursorAdapter {

  public MultiSelectCursorAdapter(Context context, int layout, Cursor c, String[] from, int[] to, int flags) {
        super(context, layout, c, from, to, flags);
    }

  @Override
  public View getView(int position, View convertView, ViewGroup parent) {
    final int fposition = position;
    View view = super.getView(position, convertView, parent);
    CheckBox checkbox = (CheckBox) view.findViewById(R.id.list_checkbox);
    checkbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            Log.d("CHECKER", "Something happened: " + fposition + " was clicked " + isChecked);
            // TODO: store id of checked items in your model
            }

    });

    return view;
    }
}

In your list row layout you need to set android:focusable="false" in order to allow clicks on list items and clicks on the checkbox of each list item.

<CheckBox
        android:id="@+id/list_checkbox"
        android:focusable="false" 
        ... >
</CheckBox>

Finally you need a model or data structure to store all checked items of your list, eg an array or list that stores identifiers for all checked items.
