Question

I am trying to change only one (maybe more) ListView row based on specific condition. I have read many answers on similar questions and tons of other tutorials but I am not able to make anything.

Exactly what I want to achieve is to have row background (easier version) or row picture (I think harder version) set different than others when row from SQLite is set at specific value.

I have got Activity that extends ListActivity and I am setting the ListView adapter like this:

private void refreshList() {
    mySQLiteAdapter = new MyDBAdapter(this);
    mySQLiteAdapter.open();
    String[] columns = { MyDBAdapter.KEY_TITLE, MyDBAdapter.KEY_GENRE,
            MyDBAdapter.KEY_PRICE, MyDBAdapter.KEY_ID };

    Cursor contentRead = mySQLiteAdapter.getAllEntries(false, columns,
            null, null, null, null, MyDBAdapter.KEY_TITLE, null);

    SimpleCursorAdapter adapterCursor = new SimpleCursorAdapter(this,
            R.layout.row, contentRead, columns, new int[] {
                    R.id.text1, R.id.detail });

    this.setListAdapter(adapterCursor);
    mySQLiteAdapter.close();
}

This function is called in onCreate method and in onResume. I want to set different color/image of row where value from column MyDBAdapter.KEY_PRICE is equal to 5. The R.layout.row is my xml file with row design.

Maybe someone can help me with this? Or at least show tutorial describing it?

Answer 1

Simply extend SimpleCursorAdapter and override bindView():

public class MyAdapter extends SimpleCursorAdapter {
    public MyAdapter(Context context, int layout, Cursor c, String[] from, int[] to) {
        super(context, layout, c, from, to);
    }

    @Override
    public void bindView(View view, Context context, Cursor cursor) {
        super.bindView(view, context, cursor);
        if(cursor.getLong(cursor.getColumnIndex(MyDBAdapter.KEY_PRICE)) == 5)
            view.setBackgroundColor(0xff00ff00);
        else // this will be the default background color: transparent
            view.setBackgroundColor(0x00000000);
    }
}
