android.view.InflateException: बाइनरी एक्सएमएल फ़ाइल लाइन # 9: कक्षा <unknown>

Question

में त्रुटि में त्रुटि मैं इस मुद्दे को घंटों और इसी तरह की त्रुटियों के लिए देख रहा हूं जिनके समाधान ने चाल नहीं की थी।

मैं इस XML फ़ाइल को विभिन्न गतिविधियों में एकाधिक सूची दृश्यों के लिए पुन: उपयोग कर रहा हूं (जो मुझे लगता है कि इसके साथ कुछ करने के लिए कुछ है) लेकिन मुझे नहीं लगता कि यह क्यों टूट जाएगा। एक्सएमएल फ़ाइल ListView में अलग-अलग आइटम का प्रतिनिधित्व करती है।

यहाँ एक्सएमएल है:

अग्रिम धन्यवाद।

Answer 1

@kiruwka के लिए धन्यवाद, समस्या ठीक हो गई है!

मुद्दा यह था कि मुझे यह सुनिश्चित करने की आवश्यकता थी कि मैं गतिविधियों में एक ही थीम का उपयोग कर रहा हूं।

Answer 2

मैं कोड को स्पष्ट रखने के लिए, फ्रेमलेआउट से स्थिर विधि की बजाय आपके संदर्भ से प्राप्त inflator का उपयोग करूंगा। FrameLayout की विरासत में वृद्धि() विधि Context.getSystemService() को कॉल करने के आसपास बस एक रैपर है, फिर फुलाए जाने पर कॉल करें। यह करने के लिए इसे बदलने का प्रयास करें:

 convertView = 
      (FrameLayout)inflater.inflate(mContext, 
              R.layout.column_post, 
              parent, 
              false); 

मुझे लगता है दुर्घटना आप देख रहे हैं इसलिए है क्योंकि आप माता-पिता के लिए अशक्त से गुजर रहे हैं और डिफ़ॉल्ट बढ़() वेरिएंट संलग्न करने के लिए नए बच्चे देखने के लिए आप का निर्माण कर रहे प्रयास करेंगे अभिभावक (जो आप नहीं करना चाहते हैं।)
