导读：我有超过10000个城市名称,我想在ListView中显示.我将这些名称存储为res / values文件夹中的city.xml文件如下 resourcesstring-array name="city" item chennai,India /itemitem Spring Creek,Australia /item.. 然后我创建一个ArrayAdapter并像这样填充list

我有超过10000个城市名称,我想在ListView中显示.我将这些名称存储为res / values文件夹中的city.xml文件

如下

<resources>
<string-array name="city"> 
<item>  chennai,India </item>
<item>  Spring Creek,Australia </item>
.
.

然后我创建一个ArrayAdapter并像这样填充listView.

String[] cityDetails = res.getStringArray(R.array.city); // <-- getting Error in this line
myAdapter = new ArrayAdapter<String>(this,R.layout.ap_details_row,R.id.aNameTV,cityDetails );
myLV.setAdapter(myAdapter);

它在API 13级及以上设备中运行良好.但是在API 13级设备下面,我收到以下错误.

任何帮助,将不胜感激.

解决方法

一些想法：

1-一次显示一页数据.向下滚动时,请加载更多数据.

2-滚动10000条记录到最后将需要永远.通过搜索表单访问您的数据.将结果限制为100条记录.

3-如果数据已排序,请将项目组合在一起并提供索引.例如,字母列表可以分成26个子集.第一页显示字母表,您必须单击一个字母才能转到子集.
