समस्या

हम लाल वृत्त में इस घटक को क्या कहते हैं ??

और मैं इस तरह से संवाद कैसे कर सकता हूं।

असल में मुझे नहीं पता कि इसका नाम क्या है, इसलिए मुझे कीवर्ड नहीं पता

उस बारे में खोजना

नोट

मुझे पता है कि किसी भी तरह एंड्रॉइड में साधारण संवाद कैसे बना सकता है

छवि विवरण यहां दर्ज करें

कल्पना कीजिए कि आप एक NumberPicker रखना चाहते हैं जो 0C से 20C तक डिग्री मान दिखाता है।

आपको अपने नंबर पिक्चर को पॉप्युलेट करने के लिए स्ट्रिंग एरे सेट करना होगा ।

सबसे पहले, अपने स्ट्रिंग को अपने मूल्यों के साथ प्रारंभ करें, जैसे: 

  स्ट्रिंग [] degreesValues ​​= new string [20]; के लिए (इंट I = 0; i & lt; 20; i ++) {डिग्री वैल्यू [i] = स्ट्रिंग.वल्यूएफ़ (i) + (चार) 0x00B0; }

फिर, बस अपने NumberPicker पर इस तरह से लागू करें: 

  NumberPicker picker = (NumberPicker) findViewById ( R.id.numberPicker); picker.setMinValue (0); picker.setMaxValue (19); picker.setDisplayedValues ​​(degreesValues);
