काम नहीं कर रहा है मैं एक ही ग्रिडलेआउट में गतिशील रूप से बनाई गई छविदृश्य पर कैप्चर की गई छवि को सेट करना चाहता हूं लेकिन यह एक नया ग्रिड लेआउट बनाता है और कैप्चर की गई छवि को नए ग्रिडव्यू पर सेट करता है।ग्रिडलेआउट में गतिशील रूप से निर्मित छविदृश्य

मुझे स्पष्ट रूप से समझ में नहीं आता है कि ग्रिडलेआउट के अंदर ग्रिड व्यू का उपयोग करने का क्या मतलब है ... आप केवल 2 कॉलम के साथ एक ग्रिड व्यू का उपयोग कर सकते हैं और जोड़ सकते हैं छवि दृश्य गतिशील रूप से। जैसा कि मैंने देखा, आप समस्या को प्रत्येक बार 'onCaptureImageResult()' में पास करते समय एडाप्टर को फिर से बनाने लगते हैं। आपको इसे एक बार बनाना चाहिए और 'NotifyDataSetChanged() 'को कॉल करके इसे रीफ्रेश करना चाहिए। – Fllo
