我做了一个活动，因为我正在使用AsyncTak进行api调用，我在DoBackground方法中显示了progressDialog，并希望在postExecute中忽略progressDialog我已经这样做但是它不起作用，我的progressDialog仍然存在，操作后打开..我的代码如下，anybuddy可以帮我解散。

答案 1 :(得分：0)
删除
if (pDialog.isShowing())
和
use if (pDialog != null)
这可以帮到你
答案 2 :(得分：0)
您应该在执行super.onPostExecute(result);时删除onPostExecute()，因此您可能不希望框架处理它。
由于您已经在onPreExecute（）中明确显示了进度对话框，因此您也可以省略isShowing()的检查，但我会建议您保持此检查，因为它不会造成任何伤害，并且几乎不会增加安全性。< / p>
答案 3 :(得分：0)
在onPostExecute()区块中，您正在呼叫super.onPostExecute(result);
@Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
// Your code
}
但是，当您覆盖onPostExecute()时，无需拨打super.onPostExecute(result);
如果你看一下AsyncTask source，你会发现超级课程什么也没做：
@SuppressWarnings({"UnusedDeclaration"})
protected void onPostExecute(Result result) {
}
