Android - 水平滑动分页的分页列表活动
我有一个实现 Runnable 的列表活动，以便我的数据获取是通过进度条完成的。数据是从网络服务中提取的。现在，我要获取所有用户，但我想更改它，以便它一次检索一页用户，而不是一次检索所有用户。
public class ActiveUsersActivity extends ProtectedListActivity implements Runnable {
ProgressDialog progress;
ArrayList<UserModel> users;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
progress = ProgressDialog.show(ActiveUsersActivity.this, "", "Loading...", true);
Thread thread = new Thread(ActiveUsersActivity.this);
thread.start();
}
@Override
public void run() {
//Get user data
users = MyService.GetAllUsers();
}
}
因此，我需要进行的修改是将运行更改为一次获取一页。这很容易，但我的问题在于如何进行实际的水平滑动。理想情况下，我想让列表向左或向右滑动，就像您滑动时主屏幕所做的那样。关于如何做到这一点有什么想法吗？
I have a list activity that implements Runnable so that my data fetch is done with a progress bar. The data is pulled from a web service. Right now, I go get all of the users, but I would like to change it so it retrieves the users one page at a time, instead of all at once.
public class ActiveUsersActivity extends ProtectedListActivity implements Runnable {
ProgressDialog progress;
ArrayList<UserModel> users;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
progress = ProgressDialog.show(ActiveUsersActivity.this, "", "Loading...", true);
Thread thread = new Thread(ActiveUsersActivity.this);
thread.start();
}
@Override
public void run() {
//Get user data
users = MyService.GetAllUsers();
}
}
So, the modifications I need to make are to change run to get one page at a time. That is easy enough, but my problem lies in how to do the actual horizontal swipe. Ideally, I would like to make the list slide left or right like the home screens do when you do a swipe. Any ideas on how to do this?

至于滑动，您看过 GestureDetector 吗？查看 OnGestureListener 及其 onFling。
As for the swiping, have you looked at the GestureDetector? Check out the OnGestureListener and its onFling.
