我尝试在android中的模块中添加旋转轮进度条。但它无法正常工作。
点击发送按钮我想添加旋转轮。告诉我在哪里添加它以及如何添加。
我的代码是：
片段发送job.java

答案 0 :(得分：1)
我认为你遗忘了.show()
Progress Dialog
pDialog.show();
并在pDialog中的onPreExecute()中实施AsyncTask，就像这样，
@Override
protected void onPreExecute() {
super.onPreExecute();
mProgressDialog = new ProgressDialog(getActivity());
mProgressDialog.setMessage("Loading please wait....");
mProgressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
mProgressDialog.setCancelable(false);
mProgressDialog.show();
}
和dismiss Progress Dialog中的onPostExecute(....)就像这样，
@Override
protected void onPostExecute(String[] result)
{
super.onPostExecute(result);
pDialog.dismiss();
}
