Android screen navigation issue -

-

मुझे एक स्क्रीन नेविगेशन सवाल मिलता है। 1. गतिविधि ए-> गतिविधि बी 2. गतिविधि बी पर, गतिविधि ए (गतिविधि बी-> गतिविधि ए) पर वापस जाने के लिए एक एक्शन बटन पर क्लिक करें 3. गतिविधि ए पर, गतिविधि बी पर वापस जाने के लिए एक रद्द करें बटन पर क्लिक करें गतिविधि ए-> गतिविधि बी)।

मैं गतिविधि बी को दो बार नहीं बनाना चाहता हूं। क्या दूसरे चरण में गतिविधि बी को बचाने का एक तरीका है? धन्यवाद।

क्या कुछ बड़ा है जो बी में आरंभ होता है जो संक्रमण को धीमा कर रहा है? मैं सिर्फ सिस्टम को इसकी बात करता हूं, आप onSavedInstanceState और onRestoreInstanceState ।

के साथ एक गतिविधि में स्थिति का अनुकूलन कर सकते हैं

So I'm trying to merge back into my trunk, but I'm getting errors saying that I Because they are not related to the ancestors but I am not clear why this is why. Here is the graph generated by TartiSesWN The trunk is at the bottom left (14698) Currently, I am starting with the merger in the trunk (15 9 7 9) from the top right, this is an example which claims that it is not related to the ancestors, some disparities in it That is what a coworker presented, and I'm not sure it could be the reason for this. If you notice, in the right middle, the branch with modification number 15406 actually divides a tag. It seems incredibly wrong to me, but I'm not sure. A few months ago the coworker did this (he does not work here anymore). However, they should be related to all ancestors because they come from all trunk, right? If this is true, then why am I getting this error? Will a tag be divided? The head of the trunk is 16063 (as per the figure), 14698 merge-s...
