क्या कोई जानता है कि यह कैसे और क्यों होता है?पेजर और सूचीदृश्य देखें

मैं क्या
एक दृश्य पेजर
के साथ मेरी sherlockfragmentactivity खोलने viewpager अंदर सूचीदृश्य जो मुझे दूसरी गतिविधि
- के पास ले जाएगा पर किसी आइटम को क्लिक था
प्रेस बटन वापस जो हमें इसमें व्यूअर के साथ गतिविधि में वापस कर देगा।
उन तीन चरणों पर पहली कार्रवाई ठीक है, हालांकि जब मैं दूसरे चरण को दोहराता हूं और तीसरा चरण कई बार तेज़ करता हूं, तो कभी-कभी यह समस्या उत्पन्न होगी।
कोई विचार यह कैसे ठीक करें?
यह मेरा कोड है:

अगर मैं समझता हूं, समस्या हमेशा प्रकट नहीं होती है, तो कभी-कभी आप बटन दबाते हैं? –
यह हमेशा होता है, लेकिन पहली बार इसे दबाएं नहीं। यह कभी-कभी दूसरे, तीसरे या अधिक पर होता है। –
'ListView' में' ViewPager' दिखाने की कोशिश कर रहा है? –
