Android में बटन का राज। भाग 3: मुख्य मेनू में बटन

मुख्य मेनू एप्लिकेशन के साथ उपयोगकर्ता इंटरैक्शन के लिए मुख्य टूल में से एक है। एंड्रॉइड 2.3.x और इससे पहले यह हार्डवेयर मेनू बटन पर "छिपा हुआ" था, और डेवलपर्स ने एक मेनू को आकर्षित किया जैसा कि वे कर सकते थे। लेकिन एंड्रॉइड 3.0 के साथ शुरू होने पर, बग को ठीक किया गया था, मेनू एक्शन बार पर एक मानक घटक बन गया, और कई नई सुविधाएँ प्राप्त कीं। हालाँकि, मेनू विकास प्रक्रिया में बहुत बदलाव नहीं हुआ है। एंड्रॉइड में मेनू केवल बटन का एक सेट नहीं है, जिस पर OnClickListener लटका सकता OnClickListener । एंड्रॉइड में, आप पहली नज़र में लगता है कि मेनू से बहुत अधिक कर सकते हैं।

इस लेख में मैं आपको बताऊंगा कि एक आधुनिक मेनू कैसे बनाया जाता है, विभिन्न स्क्रीन आकारों के लिए इसे कैसे अनुकूलित किया जाए, रेडियो बटन को सीधे मेनू में कैसे बनाया जाए, और मेनू बटन की दृश्यता को गतिशील रूप से कैसे नियंत्रित किया जाए, आपके एप्लिकेशन के उन कार्यों को छिपा देना जो उस पर काम नहीं करेंगे। या कोई अन्य स्मार्टफोन। लेख के पाठ्यक्रम में मैं विभिन्न मेनू विकल्पों का सबसे विस्तृत विवरण देने की कोशिश करूंगा, साथ ही विषय पर आधिकारिक प्रलेखन के लिंक भी दूंगा।



यह एक ही एप्लिकेशन के मेनू अलग-अलग दिख सकता है।

हमारा पहला मेनू बटन

एंड्रॉइड में मेनू को संसाधन फ़ाइलों में वर्णित किया गया है या प्रोग्राम कोड द्वारा उत्पन्न किया गया है। कई कारणों से पहले विकल्प की सिफारिश की जाती है: विकास की गति, दृश्यता, रखरखाव में आसानी। मेनू संसाधन res अनुप्रयोग संसाधन निर्देशिका के menu उपनिर्देशिका में स्थित हैं। menu निर्देशिका बनाएं, फिर एक नई Android XML File बनाएं:



संसाधन प्रकार Menu चयन करें, फ़ाइल नाम दर्ज करें। चूंकि विभिन्न गतिविधि मेनू में सबसे अधिक संभावना होगी, इसलिए मैं सुझाव देता हूं कि आप मेनू के संसाधन फ़ाइलों के नाम को गतिविधि के नाम से बांधें।

खुलने वाले संपादक में, हमारे मेनू के पहले बटन के लिए कोड दर्ज करें:

 <menu xmlns:android="http://schemas.android.com/apk/res/android" > <item android:id="@+id/menuPurchasesListNewRecord" android:orderInCategory="10" android:showAsAction="always|withText" android:title="@string/menuPurchasesListNewRecord" android:icon="@drawable/content_new"> </item> </menu> 

आइए नजर डालते हैं उपयोग की गई विशेषताओं पर:

• android:id इंगित करता है कि बाद में कोड में एक बटन को दूसरे से अलग करने के लिए।
• android:orderInCategory दूसरों के सापेक्ष हमारे बटन के क्रम को इंगित करता है। आदेश को 10 या 100 की वेतन वृद्धि में निर्दिष्ट करें, इससे भविष्य में बाकी के आदेश को फिर से व्यवस्थित किए बिना किसी भी स्थान पर नए तत्वों को जोड़ा जा सकेगा।
• android:showAsAction सबसे दिलचस्प पैरामीटर है, क्योंकि यह विभिन्न स्थितियों में मेनू आइटम के व्यवहार को नियंत्रित करता है। इसके कई अर्थ हो सकते हैं:
  • ifRoom - एक्शन बार में एक तत्व ifRoom दिखाएं जब इसके लिए पर्याप्त जगह हो। यदि पर्याप्त जगह नहीं है, तो आइटम स्वचालित रूप से अतिरिक्त मेनू (एक दूसरे के ऊपर तीन डॉट्स द्वारा दिखाया गया है) में छिपा दिया जाएगा। यह डिवाइस के स्क्रीन आकार के आधार पर मेनू को अनुकूलित करने का सबसे अच्छा तरीका है। बड़े टैबलेट स्क्रीन पर, एक्शन बार बटनों से भरा होगा, और छोटे फोन पर सबसे महत्वपूर्ण बटन दिखाए जाएंगे, जबकि बाकी भी पहुंच सकते हैं, लेकिन केवल एक अतिरिक्त मेनू के माध्यम से। ध्यान रखें कि अतिरिक्त मेनू केवल उन स्मार्टफ़ोन पर एक्शन बार में प्रदर्शित होता है, जिनमें हार्डवेयर मेनू बटन नहीं होता है।
  • withText - android:title द्वारा निर्दिष्ट पाठ android:title संपत्ति बटन आइकन के बगल में दिखाई जाएगी। इस पैरामीटर को दूसरों के साथ संयोजन में निर्दिष्ट किया जा सकता है, मापदंडों को अलग करना |
  • never - बटन कभी भी एक्शन बार पर दिखाई नहीं देगा, भले ही उसके लिए जगह हो। आपको हमेशा एक अतिरिक्त मेनू के माध्यम से इस तरह के बटन को प्राप्त करना होगा।
  • always - हमेशा एक्शन बार में बटन दिखाएं। इस पैरामीटर का दुरुपयोग नहीं किया जाना चाहिए, चूंकि छोटे फोन पर, बटन अन्य एक्शन बार तत्वों को क्रॉल करना शुरू कर सकते हैं, उदाहरण के लिए, एप्लिकेशन हेडर के लिए। प्रत्येक गतिविधि के लिए अधिकतम एक सबसे महत्वपूर्ण बटन को परिभाषित करें, जिसके बिना यह असंभव है, और केवल इसके साथ always चिह्नित करें। बाकी (और संभवतः सभी) ifRoom होना चाहिए।
  • collapseActionView - आपको एक बटन बनाने की अनुमति देता है जो कार्रवाई पट्टी में एक अतिरिक्त View तत्व खोलता या छुपाता है। उदाहरण के लिए, आप खोज चिह्न में इस तरह के एक पैरामीटर को सेट कर सकते हैं, इसे खोज क्वेरी दर्ज करने के लिए सीधे एक्शन बार क्षेत्र में दिखा सकते हैं।
• android:title - मेनू बटन के शीर्षक को परिभाषित करता है। इसे एक्शन बार में आइकन के बगल में या अतिरिक्त मेनू में एक तत्व के नाम के रूप में प्रदर्शित किया जा सकता है।
• android:icon - बटन आइकन।

मेनू के लिए प्रतीक

यदि आप होलो की शैली में एक एप्लिकेशन विकसित कर रहे हैं, तो आप Google से तैयार किए गए आइकन का उपयोग कर सकते हैं, जो सभी के लिए आधिकारिक साइट से मुफ्त में डाउनलोड करने के लिए उपलब्ध है।

माउस के सेट को अंधेरे के लिए अलग से और लाइट होलो थीम के लिए अलग-अलग स्क्रीन आकार के लिए प्रस्तुत किया जाता है। यदि आप एक टीम में एक डिजाइनर का खर्च नहीं उठा सकते हैं, तो यह सेट बस अपूरणीय है।

किसी गतिविधि में एक मेनू कनेक्ट करना

संसाधन से मेनू डाउनलोड करना बहुत तेज़ है। गतिविधि कोड खोलें और onCreateOptionsMenu विधि को ओवरराइड करें:

  @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.your_activity_menu, menu); return true; } 

अब मेनू प्रदर्शित होता है, लेकिन जब आप बटन पर क्लिक करते हैं, तो कुछ भी नहीं होता है। आप कोड पर बटन के साथ या सीधे XML संसाधन में सीधे हैंडलर विधि को android:onClick संपत्ति में सेट करके बटन को हैंग कर सकते हैं। समान कोड बनाने के लिए, आपको गतिविधि में onOptionsItemSelected पद्धति को onOptionsItemSelected :

  @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case R.id.menuPurchasesListNewRecord: // TODO:    return true; } return super.onOptionsItemSelected(item); } 

एक सबमेनू बनाएँ

सबमेनू तब उपयोगी होता है जब हम एक्शन बार में एक्शन प्रस्तुत करने के तरीके को स्पष्ट करना चाहते हैं। उदाहरण के लिए, हमारे पास एक खरीदारी सूची और एक "सॉर्ट" बटन है। एक बटन के क्लिक पर, आपको यह पता लगाना होगा कि उपयोगकर्ता किस आइटम को सूची आइटम सॉर्ट करना चाहता है: उत्पाद श्रेणी से, नाम से या उस क्रम से जिसमें वे सूची में जोड़े जाते हैं। आइए इस मामले के लिए सबमेनू कोड देखें:

  <item android:id="@+id/menuPurchasesListSortOrder" android:orderInCategory="20" android:showAsAction="ifRoom" android:title="@string/menuPurchasesListSortOrder" android:icon="@drawable/collections_sort_by_size"> <menu> <group> <item android:id="@+id/menuPurchasesListSortOrderCategory" android:orderInCategory="100" android:showAsAction="never" android:title="@string/menuPurchasesListSortOrderCategory"/> <item android:id="@+id/menuPurchasesListSortOrderName" android:orderInCategory="200" android:showAsAction="never" android:title="@string/menuPurchasesListSortOrderName"/> <item android:id="@+id/menuPurchasesListSortOrderAddTime" android:orderInCategory="300" android:showAsAction="never" android:title="@string/menuPurchasesListSortOrderAddTime"/> </group> </menu> </item>
