मेरे पास ListViewमेरे दूसरे activity.OnItemClickहिस्से में एक है जिसे मैंने एक वेबसर्विस कहा है और डेटा लाने की कोशिश कर रहा हूं। और उसके बाद मैं तीसरी गतिविधि पर जा रहा हूं जिसमें ListViewपिछली गतिविधियों का विवरण भी है ListView।
मैं इसे आबाद करने से पहले एक प्रगति संवाद प्रदर्शित करना चाहता हूं ListView।
मुझे समझ में नहीं आता कि यह कैसे करना है ListView? क्या किसी को पता है कि यह कैसे करना है?

पंकज- मुझे पता है कि प्रोग्रेसियलॉग को कैसे प्रदर्शित किया जाता है, लेकिन मैं प्रोग्रेस डायलॉग के बजाय केवल प्रोग्रेसबार सर्कल प्रदर्शित करना चाहता हूं।
