When I first joined the company, I heard technicians talk about the "ranking" function in the source code of the live APP. The first thing I thought of was the ranking of students' achievements. Those who were on the list were complacent until the next exam, and those who were on the list were crying. In fact, even if they were on the list, there was no substantive reward, and there was little difference between the 10th place on the list and the 11th place on the list, but we still tried our best to make ourselves "on the list", To meet psychological needs.
In the live broadcast APP, the role of the leaderboard for "local tyrants" is also set to meet their psychological needs and stimulate users to reward the list. For the anchor, it is useful to increase popularity and provide a reference for the anchor's traffic realization activities such as receiving advertisements.
This article mainly describes how to realize the leaderboard function in the source code of Android live app. As shown in the figure below, there are two buttons: revenue list and contribution list on the home page of cloudleopard live app. Click to enter the corresponding leaderboard list page respectively.
Whether you enter the revenue list or the contribution list, you can switch to another list again (two-way). The top of the revenue list shows the top three anchors with the highest revenue, and the top of the contribution list shows the three users with the most consumption. The following users are listed in reverse order of revenue and consumption. Users can click the corresponding avatar to enter the home page.
The source code of some live broadcast app s is as follows:
public class RankActivity extends AbsActivity {
public static void forward(Context context, int position) {

The above is the whole content of how to realize the ranking function in the Android live app source code. In addition to the ranking function, there are many functions in the cloud leopard live app source code to promote users' reward and promote platform profitability. The specific content will be released gradually in the future. Please look forward to it.
