How can I make a ProgressDialog be cancelable by the back button but not by a screen tap?

问题

I would like to make a ProgressDialog cancelable by the back button but not by a screen tap. Currently I use setCancelable(true).

However, in some newer devices a tap on the screen also cancels the ProgressDialog. I'd like to disable the screen tap action while the ProgressDialog is shown.

回答1:

Use setCanceledOnTouchOutside(false).

回答2:

Try this it will help you:

ProgressDialog pd = ProgressDialog.show(main.this, "", "Loading. Please wait...", true);
pd.setCancelable(true);`
