销毁Android中的活动问题

Question

Hi I am using the button for bottom tab bar in android like iphone. I have three screens and showing three button in all the screens. I used the below coding for each button in each screen.

Intent intentNavOne = new Intent(ScreenOne.this,
                    ScreenTwo.class);
            intentNavOne .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            intentNavOne .addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);

            intentNavOne .addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
            startActivity(intentNavOne );

Now the problem is some times the flow of the navigation changed. I just want the solution. Any alternate way to achive my task.Thanks in advance.

Answer 1

在您要开始新活动的活动中调用finish() ，这将停止该活动的生命周期。

Answer 2

As a developer I have faced same problem that you are facing now with the buttons to show tabs as in iphone and finally I switched to tabbars of android.

I would suggest you that use tabbars instead of buttons as navigation will be very smooth you do not have to bother about previous activity .

check below links for creating tabbars in android they are good tutorials
