Android में कस्टम नेविगेशन ड्रॉअर बनाना

यह उदाहरण दर्शाता है कि Android में कस्टम नेविगेशन ड्रॉअर कैसे बनाया जाता है।

चरण 1 - नया प्रोजेक्ट बनाएं

Android Studio में File → New Project पर जाएं और नया प्रोजेक्ट बनाने के लिए सभी आवश्यक विवरण भरें।

चरण 2 - res/layout/activity_main.xml में कोड जोड़ें
