這個很簡單 就是為了說明別忘了adapter.notifyDataSetChanged();

喚醒一下，其實這個喚醒也就是在button下用 或者在別的控件下調(diào)用 如果是在getView下就不必了

java代碼：

public class DynamicListItems extends ListActivity {

private static final String ITEM_KEY = "key";

ArrayList<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>();

private SimpleAdapter adapter;

private EditText newValue;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.dynamic_list);

newValue = (EditText) findViewById(R.id.new_value_field);

setListAdapter(new SimpleAdapter(this, list, R.layout.row, new String[] { ITEM_KEY }, new int[] { R.id.list_value }));

((ImageButton) findViewById(R.id.button)).setOnClickListener(getBtnClickListener());

}

private OnClickListener getBtnClickListener() {

return new OnClickListener() {

public void onClick(View view) {

try {

HashMap<String, String> item = new HashMap<String, String>();

item.put(ITEM_KEY, newValue.getText().toString());

list.add(item);

adapter.notifyDataSetChanged();

} catch (NullPointerException e) {

Log.i("[Dynamic Items]", "Tried to add null value");

}

}

};

}

}
