从项目的SimpleAdapter / ListView中检索原始HashMap按

Question

我有一个填充ListView的SimpleAdapter，但是当用户按下一个项目时，我希望能够获得用于填充所单击行的原始HashMap。不幸的是，我所能得到的只是一个只支持toString（）的Object。从用户单击的视图中获取字符串是没有用的，因为它不是唯一标识符。

如何为用户点击的行恢复数据？

ArrayList<HashMap<String, String>> reformedBundle = new ArrayList<HashMap<String, String>>();
// [...]
mResultsAdapter = new SimpleAdapter(this,
    reformedBundle, R.layout.resultrow,
    new String[] { "ProviderName", "Street", "City" },
    new int[] { R.id.tvField1, R.id.tvField2, R.id.tvField3
});

lvResults.setAdapter(mResultsAdapter);

lvResults.setOnItemClickListener(new OnItemClickListener() {

public void onItemClick(AdapterView<?> parent, View view, int pos, long id) {
            // Here's where I want to get the original HashMap<String, String> so I can query other keys in the HashMap
        }
    });

Answer 1

我存储在一个成员变量中。

private ArrayList<HashMap<String, String>> reformedBundle;

...

lvResults.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> parent, View view, int pos, long id) {
        HashMap<String, String> map = reformedBundle.get(pos);
    }
});
