Question

I’m using the following code to use a ListView in CustomAlertDialog Layout.

public void onButtonClicked(View v) {
    Toast.makeText(this,
            Messages.getString("OSListActivity.195"), Toast.LENGTH_SHORT).show(); //$NON-NLS-1$
    LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View view = inflater.inflate(R.layout.buttondialog, null);
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setView(view);
    ListView mbListView = (ListView) view.findViewById(R.id.mblist);
    builder.setTitle(Messages.getString("OSListActivity.196"))
            .setNeutralButton(Messages.getString("OSListActivity.197"),
                    null);
    MatrixCursor dcursor = propmanager.propCursor();
    if (dcursor.moveToFirst()) {
        startManagingCursor(dcursor);
        String[] from = { "name", "value" };
        int[] to = { R.id.mbname, R.id.mbvalue };
        SimpleCursorAdapter dadapter = new SimpleCursorAdapter(this,
                R.layout.mblistrow, dcursor, from, to);
        mbListView.setAdapter(dadapter);
    }
    builder.show(); //$NON-NLS-1$ //$NON-NLS-2$
}

However I’m getting the following error. Why? What am I doing wrong here?

Answer 1

You are trying to use a cursor that requires a column called _id. Add a column (_id) in your table or include your primary key column in query as (yourColumn AS _id) to fix this issue. For more info
