में छवि देखने के लिए छवि पर क्लिक करें यह एक ग्रिडव्यू है जो जेसन से छवि प्राप्त करता है। और यह ठीक काम करता है। मैं पूरी छवि दिखाने के लिए इस ग्रिडव्यू में छवि पर क्लिक करना चाहता हूं और इसे स्लाइड कर सकता हूं। मुझे लगता है कि इस समस्या का समाधान Viewpager का उपयोग किया जाता है।ग्रिडव्यू - व्यूपर
छवि दिखाने के लिए मैं ग्रिडव्यू में छवि कैसे क्लिक कर सकता हूं और स्लीड कर सकता हूं?

अधिक है कि तुलना में विस्तार कर सकते हैं डाउनलोड करने के लिए प्रयास करें। मुझे पता है कि मुझे एक और गतिविधि वर्ग और लेआउट बनाना होगा। लेकिन मुझे नहीं पता कि कोड कैसे करें। – kongkea
