How to block UI for some seconds in android?

问题

How can i block UI from all interactions for some seconds by user in Android?

I would like to know, how to do this with some delay timing like wait(5000);

回答1:

You can override dispatchTouchEvent and stop the call to super.dispatchTouchEvent(ev); Any touch event will have to go through this method before it is handled.

Set a boolean that you control and use it in the method to determine whether you wish to block control.

private boolean stopUserInteractions = false;

public boolean dispatchTouchEvent(MotionEvent ev) {
    if (stopUserInteractions) {
        return true;
    } else {
        return super.dispatchTouchEvent(ev);
    }
}

Show Non-cancelable progress dialog and close it by code when you want.......

You can pop up a modal, non-cancelable progress dialog that blocks the user from doing anything. However, you should never block the UI thread itself.

Use ProgressDialog in UI Block time. Set ProgressDialog cancel-able false. So user do not able to access UI.

Thanks.

As your Question is Short, you will get answer in that manner.

You can use Thread or AsyncTask for making some ProgressDialog being Visible for the User.
