Listview OnItemclicklistener在Switch case Statement中没有响应

Question

我正在处理一个应用程序，在OnItemclick方法中，我使用了listview的Switch语句，当我点击位置0时，它显示位置0项。当我在同一时间点击位置1时它没有响应。 这是代码：

        list = (ListView) findViewById(R.id.list);

        list.setAdapter(new ArrayAdapter<String>(this,

                android.R.layout.simple_list_item_checked, sims));

        list.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
                Selectitem(position);

                 switch (position) {
                 case 0:
                 mapBeginConfigcities();
                 // mapBeginConfig();
                 loadUI();
                 mapEndConfig();
                 Toast.makeText(MainActivity.this, "0"+position,
                         Toast.LENGTH_SHORT).show();
                 break;

                 case 1:
                 Toast.makeText(MainActivity.this, "1" + position,
                 Toast.LENGTH_SHORT).show();
                 mapBeginRoadsfill();
                 loadUI();
                 mapEndConfig();
                 Toast.makeText(MainActivity.this, "1" + position,
                         Toast.LENGTH_SHORT).show();
                 break;

                 case 2:
                 Toast.makeText(MainActivity.this, "2" + position,
                 Toast.LENGTH_SHORT).show();

                 break;
                 case 3:
                 Toast.makeText(MainActivity.this, "3" + position,
                 Toast.LENGTH_SHORT).show();
                 break;

                 default:

                 break;
                 }

            }

            public void Selectitem(int position) {
                // TODO Auto-generated method stub
                list.setItemChecked(position, true);
                setTitle(sims[position]);

            }

            public void setTitle(String title) {
                getSupportActionBar().setTitle(title);

            }
        });
