I have a list view that is being populated from an SQLite database u开发者_如何学JAVAsing the SimpleCursorAdapter. One of the columns being returned in the cursor is an integer value 0 or 1. In my list view, I would like to display this in a more friendly form (ie. "Yes" or "No") and possibly with different text colors for each. Here is my source:
Cursor c = dbHelper.fetchAllItems();
startManagingCursor(c);
String[] from = {"deployed", "designation", "serial"};
int[] to = {R.id.deployed, R.id.designation, R.id.serial};
setListAdapter(new SimpleCursorAdapter(this, R.layout.list_item, c, from, to));
How would I conditionally switch elements and/or properties in the layout when the SimpleCursorAdapter simply maps each view to a column name. (Is it safe to assume I can't use SimpleCursorAdapter to accomplish this?)
Solved by adding a custom adapter, extending CursorAdapter
Modification:
Cursor c = dbHelper.fetchAllItems();
startManagingCursor(c);
setListAdapter(new RowAdapter(this, c));
New nested class:
private static class RowAdapter extends CursorAdapter {
public RowAdapter(Context context, Cursor c) {
super(context, c);
}
public void bindView(View view, Context context, Cursor c) {
TextView vDesignation = (TextView) view.findViewById(R.id.designation);
TextView vSerial = (TextView) view.findViewById(R.id.serial);
TextView vDeployed = (TextView) view.findViewById(R.id.deployed);
String designation = c.getString(c.getColumnIndexOrThrow("designation"));
String serial = c.getString(c.getColumnIndexOrThrow("serial"));
int deployed = c.getInt(c.getColumnIndexOrThrow("deployed"));
vDesignation.setText(designation);
vSerial.setText(serial);
vDeployed.setText(deployed > 0 ? R.string.yes : R.string.no);
vDeployed.setTextColor(deployed > 0 ? view.getResources().getColor(R.color.yes) : view.getResources().getColor(R.color.no));
}
public View newView(Context context, Cursor c, ViewGroup parent) {
LayoutInflater inflater = LayoutInflater.from(context);
View view = inflater.inflate(R.layout.list_item, parent, false);
bindView(view, context, c);
return view;
}
}
