如何通过后退按钮取消ProgressDialog，而不是通过屏幕点击取消？

Question

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.

Answer 1

使用setCanceledOnTouchOutside（false） 。

Answer 2

Try this it will help you:

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