I am trying to implement a listview with checkbox so that when a check box is checked the list row will be removed. I am populating the listview with a cursor and this is working fine and the checkbox is being displayed.
What I am having trouble with is figure out how to get the _id of the row of the box that has been checked.
Can anyone show me how to implement something like this
ListView and CheckBox
Cursor cursor = db.getAllItems();
//String[] columns = new String[] {db.KEY_NAME, db.KEY_CODE, db.KEY_ROWID};
String[] columns = new String[] {db.KEY_ITEM_NAME, db.KEY_MEASUREMENT, db.KEY_UNIT};
int[] to = new int[] {R.id.ingredientName, R.id.ingredientMeasurement, R.id.ingredientUnit};
final SimpleCursorAdapter myCursorAdapter = new SimpleCursorAdapter(this,R.layout.row4, cursor, columns, to, 0);
final ListView shoppingList = (ListView) findViewById(R.id.shoppingList);
shoppingList.setAdapter(myCursorAdapter);
CheckBox deleteCheck = (CheckBox)findViewById(R.id.checkBox1);
deleteCheck.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
if (isChecked){
// How do I get the list item clicked to delete row?
}
}
});
XML - Row.4.xml

Use this custom cursor adapter and handle onCheckedChanged here in this adapter.
import android.content.Context;
import android.database.Cursor;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.SimpleCursorAdapter;
public class CustomAdapter extends SimpleCursorAdapter implements CompoundButton.OnCheckedChangeListener {
private Context mContext;
private Context appContext;
private int layout;
private Cursor cr;
private final LayoutInflater inflater;
public CustomAdapter(Context context, int layout, Cursor c, String[] from, int[] to) {
super(context, layout, c, from, to);
this.layout = layout;
this.mContext = context;
this.inflater = LayoutInflater.from(context);
this.cr = c;
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
return inflater.inflate(layout, null);
}
@Override
public void bindView(View view, Context context, Cursor cursor) {
super.bindView(view, context, cursor);
CheckBox checkBox1 = (CheckBox) view.findViewById(R.id.checkBox1);
checkBox1.setOnCheckedChangeListener(this);
int columnIndex = cursor.getColumnIndex(your column here);
int columnvalue = cursor.getInt(columnIndex);
checkBox1.setTag(columnvalue);
}
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
int id = (Integer) buttonView.getTag();
}
}
