我在下面的代码中将ListView项值访问为字符串并在alert中显示它?
ListView shot = getListView();
shot.setOnItemClickListener(this);
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) {
String S = arg1.getContext().toString();
AlertDialog.Builder alertbox = new AlertDialog.Builder(this);
// set the message to display
alertbox.setMessage(S).show();
}

也许这个例子可以帮到你
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
Toast.makeText(getApplicationContext(), ((TextView) view).getText(),
Toast.LENGTH_SHORT).show();
}
});

这将为您提供所点击项目的准确值。检查日志
ListView shot = getListView();
shot.setOnItemClickListener(this);
public void onItemClick(AdapterView<?> parent, View view, int position,long id) {
String val =(String) parent.getItemAtPosition(position);
System.out.println("Value is "+val);
}

也许你可以试试这个
String data = (String)shot.getItemAtPosition(arg2);
AlertDialog.Builder adb = new AlertDialog.Builder(arg1.getContext());
adb.setMessage(data).show();

获取模型的价值
adaptor.getItem(位置).getCardName();
