CoordinateSystemRenderer के लिए कार्यान्वयन क्या है?
मैं आज ही आवश्यकता से मुलाकात की और कोशिश की, यह वास्तव में काम करता है कि इसका मतलब है, आप एक ही गतिविधि में 2 GLSurfaceView डाल सकते हैं।
कुछ ध्यान दिया जाने,
GLRender में, जब onSurfaceChanged शुरू हो जाती है, तो आप अपने व्यूपोर्ट- आकार बदलने चाहिए 2
GLSurfaceView के साथ, धागा प्रस्तुत करना 2 हो जाएगा, तो सिंक्रनाइज़ समस्या हुई हो जाएगा की जरूरत है। यह के कार्यान्वयन पर निर्भर करता है।

पहली बात यह है कि मुझ पर बाहर कूदता है कि आपके नेस्टेड LinearLayout fill_parent पर सेट किया जाता है। मैं यह सुनिश्चित करने के लिए जांच करूंगा कि आपके दोनों GLSurfaceViews को शून्य-शून्य ऊंचाई के साथ रखा जा रहा है। यह मामला हो सकता है कि वे दोनों चित्रकारी हैं, लेकिन एक की 0 पिक्सेल की ऊंचाई है और इसलिए अदृश्य है। दो 'GLSurfaceViews' के बजाय –
, अपने आप को बनाने के लिए/एक जीएल धागा और संदर्भ का प्रबंधन, दो' SurfaceViews' (नहीं 'GLSurfaceViews') के लिए आवेदन है कि बेहतर हो सकता है। [फ्रेडन की चर्चा और ग्राफिका से लिंक] देखें (http://stackoverflow.com/a/22746240/199364)। – ToolmakerSteve
