Question

我的职能是找到一份清单,列出我希望在一份清单中显示的项目清单。接着,在名单上所列活动的地点,我有以下法典:

    View header = (View) getLayoutInflater().inflate(
            R.layout.list_header_view, null);
    getListView().addHeaderView(header);

    TextView title = (TextView) findViewById(R.id.list_view_name);
    title.setText("Events nearby: ");

    setListAdapter(new ArrayAdapter<String>(this, R.layout.event_list_item,
            findLocalEvents()));

    ListView lv = getListView();
    lv.setTextFilterEnabled(true);

    // LIST ITEM IS CLICKED
    lv.setOnItemClickListener(...)

我想做的是展示一些东西(例如“Loading”),以告诉用户名单正在有人居住,然后在发现的当地企业最终运转时展示所有物品。感谢。

你在这里需要显示装货信息。遵循守则将给你一个想法,说明如何对待。

ProgressDialog dialog = ProgressDialog.show(this, "Validating Postcode/Zipcode", 
                                    "Please wait...!", true);
startThread();

private void startThread() {
        new Thread(new Runnable() {

            public void run() {
                try {
                    ArrayList<t> arr = NetworkCalls.fetchCategoriesByZipCode();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                runOnUiThread(categoriesReturned);
            }                   
        }).start(); 
    }

private Runnable categoriesReturned = new Runnable() {

        public void run() {
               //load listview
            }
};
