2010-ListView的世界，其中包含许多有用的信息。
基本上，我要做的只是创建一个自定义ArrayAdapter并覆盖getView（）。查看下面的代码。
public class Lwm extends ListActivity { private TextView mSelection; private List<MonitorObject> mMonitorObjects; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mMonitorObjects = getMonitorObjects(); setContentView(R.layout.main); setListAdapter(new CustomAdapter()); mSelection = (TextView)findViewById(R.id.selection); } @Override public void onListItemClick(ListView parent, View v, int position, long id){ mSelection.setText("Selection length is: " + mMonitorObjects.get(position).toString().length()); } private class CustomAdapter extends ArrayAdapter<MonitorObject> { CustomAdapter() { super(Lwm.this, R.layout.row, R.id.label, mMonitorObjects); } @Override public View getView(int position, View convertView, ViewGroup parent) {View row = convertView; if (row == null) { // This gives us a View object back which, in reality, is our LinearLayout with // an ImageView and a TextView, just as R.layout.row specifies. LayoutInflater inflater = getLayoutInflater(); row = inflater.inflate(R.layout.row, parent, false); } TextView label = (TextView) row.findViewById(R.id.label); label.setText(mMonitorObjects.get(position).toString()); ImageView icon = (ImageView)row.findViewById(R.id.icon); MonitorObject mo = getMonitorObjects().get(position); if (mo.ismAlarm()) { icon.setImageResource(R.drawable.alarm); row.setBackgroundColor(Color.RED); } else if (mo.ismWarning()){ icon.setImageResource(R.drawable.warning); row.setBackgroundColor(Color.YELLOW); } else { icon.setImageResource(R.drawable.ok); row.setBackgroundColor(Color.GREEN); } return row;} } private List<MonitorObject> getMonitorObjects() { List<MonitorObject> mos = new ArrayList<MonitorObject>(); mos.add(new MonitorObject(15000, 20000, 25000)); mos.add(new MonitorObject(15000, 14000, 18000)); mos.add(new MonitorObject(15000, 12000, 14000)); mos.add(new MonitorObject(100, 200, 250)); mos.add(new MonitorObject(3000, 2500, 3500)); return mos; }}
