एंड्रॉइड में दो गतिविधियों के बीच 3 डी संक्रमण कैसे लागू करें?

Question

मेरे पास एक एंड्रॉइड एप्लिकेशन है और दो गतिविधियों के बीच स्विच करते समय मैं 3 डी संक्रमण लागू करना चाहता हूं ... मुझे विधि overridePendingTransition() पता है लेकिन इसमें 3 डी के लिए कोई एनीमेशन नहीं है .. तो यह कैसे किया जा सकता है?

Answer 1

मैंने गतिविधियों के बीच 3 डी घन संक्रमण का उपयोग किया था। क्रेडिट रॉबर्ट हेम के पास जाता है जो इस कार्यक्रम के डेवलपर हैं।

Answer 2

यहाँ रिवर्स एनीमेशन कार्यक्षमता के साथ @Vipul शाह कोड का विस्तार है

ऐड निम्नलिखित "ActivitySwitcher"

public static void animationInReverse(View container, WindowManager windowManager) { 
    animationInReverse(container, windowManager, null); 
} 

public static void animationInReverse(View container, WindowManager windowManager, AnimationFinishedListener listener) { 
    apply3DRotation(-90, 0, false, container, windowManager, listener); 
} 

public static void animationOutReverse(View container, WindowManager windowManager) { 
    animationOut(container, windowManager, null); 
} 

public static void animationOutReverse(View container, WindowManager windowManager, AnimationFinishedListener listener) { 
    apply3DRotation(0, 90, true, container, windowManager, listener); 
} 

और पहली गतिविधि

में जोड़ने के लिए में विधि

@Override 
protected void onResume() { 
    if (isFromOncreate) { 
     isFromOncreate = false; 
     ActivitySwitcher.animationIn(findViewById(R.id.container), getWindowManager()); 
    } else { 
     ActivitySwitcher.animationInReverse(findViewById(R.id.container), getWindowManager()); 
    } 
    super.onResume(); 
}
