public class ServerRequests {
    ProgressDialog progressDialog;
    public static final int CONNECTION_TIMEOUT = 1000 * 15;
    public static final String SERVER_ADDRESS = "http://manibala.comlu.com/";

    public ServerRequests(Context context) {
        // Instantiate Progress Dialogue
        progressDialog = new ProgressDialog(context);
        // Set the attribute of Progress Dialogue
        progressDialog.setCancelable(false);
        progressDialog.setTitle("Processing");
        progressDialog.setMessage("Please wait...");
    }

    public void storeUserDataInBackground(User user, GetUserCallBack callBack) {
        progressDialog.show();
    }
}

Answer 1

在Java包中创建接口。例如：make文件名为GetUserCallback.java

interface GetUserCallback {
    public abstract void done(User returnedUser);
}

它完成了！
