我正在尝试使用 SimpleAdapter 让我的头脑清醒,但是我正在为一个项目而苦苦挣扎。
如何返回所选视图的数据数组?
这是我用来生成它的代码。
// Data for List Adapter
List<Map<String, Object>> resourceNames = new ArrayList<Map<String, Object>>();
// Make Hashmap of Results Hashmaps
generateData(resourceNames);
//Source information from Hashmap keys (FROM)
String keynames[]={"names","descriptions"};
// Target Views for Data (TO)
int[] targets = new int[] { R.id.textfield_name,R.id.textfield_description};
// Create my Simple Adapter
SimpleAdapter adapter = new SimpleAdapter(this, resourceNames,
R.layout.listrow, keynames,targets
);
setListAdapter(adapter);
}
然后,我使用 onclick 侦听器使用以下代码获取数据:
setContentView(R.layout.listview);
final ListView listView = getListView();
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3) {
Toast.makeText(arg1.getContext(),
getString(R.string.selected) + " " + position,
Toast.LENGTH_SHORT).show();
// How do I return the entire data that I used
}
});
我可以在上面看到如何获取数据在数组中的位置 - 但是如何返回视图中显示的实际结果数据?
