问题 I'm trying to mock up a USSD interaction in Android by creating a series of dialog menus that you can go through in Android. I'm trying to make it so that in between dialogs, there is a progress dialog that says "USSD code running..." However, upon clicking the positive button, when I try to run a ProgressDialog with a runnable timer and follow it with the next dialog called FirstTimeUser, they just layer one on top of another, even if I try to separate them with another timer. How can I make

问题 I have the following three classes: When I try to show a progressDialog when the WorkingThread is running, the ProgressDialog only shows up after the WorkingThread is done. What am I doing wrong?

问题 Goal: Have a ProgressDialog which shows "Loading..." until next Activity is completely loaded and shown on screen. Tried with ProgressDialog context and activity set to originating Activity.

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.
