我有一个带有按钮Apply的列表。当用户点击“应用”按钮时，会调用一个弹出窗口，用户输入一些值并将值发送到Web服务。当我获得成功响应时，我想要刷新我的webservice列表，以便应用按钮上的文本应更改为应用
CustomAdapter

您可以将新数据提供给阵列和电话：
adapter.notifyDatasetChanged();
它将刷新ListView。

获得成功后..您可以将该值存储到list，然后只需致电yourAdapter.notifyDataSetChanged()
答案 2 :(得分：0)
尝试 -
applyBtn=(Button) v.findViewById(R.id.apply);
applyBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
myadapter.notifyDataSetChanged();
}
});
答案 3 :(得分：0)
创建与ArrayList<Integer> status大小相同的ArrayList<HashMap<String, String>> data;现在，无论何时发出请求并获得成功，请将位置添加到status。然后在getView（）方法中：
if(status.contains(new Integer(position))) {
button.setText("Applied");
}
else {
button.setText("Apply");
}
此外，在您将状态添加到状态arraylist之后，请致电adapter.notifyDataSetChanged()。这将确保刷新列表。
