java - SwipeRefreshLayout 动画卡住 onRefresh()

当我滑动刷新 SwipeRefreshLayout 的动画显示时，但它在 onRefresh() 运行时被卡住，并且只有在 onRefresh() 完成时才开始旋转。

主要 Activity

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    myFAB = (FloatingActionButton) findViewById(R.id.myFAB);
    recyclerView = (RecyclerView) findViewById(R.id.rv);
    recyclerView.setHasFixedSize(true);
    LinearLayoutManager llm = new LinearLayoutManager(this);
    recyclerView.setLayoutManager(llm);
    recyclerView.addItemDecoration(new SimpleDividerItemDecoration(this));
    callCadastroEncoemnda();
    callPackageList();
    swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipeRefreshLayout);
    swipeRefreshLayout.setOnRefreshListener(this);
    swipeRefreshLayout.setColorSchemeResources(
            android.R.color.holo_blue_bright,
            android.R.color.holo_green_light,
            android.R.color.holo_orange_light,
            android.R.color.holo_red_light);
}

刷新:

@Override
public void onRefresh() {
    swipeRefreshLayout.setRefreshing(true);
    Update.updateAll(MainActivity.this);
    //Check if the data change
    if (!packages.equals(dao.getPackages())) {
        adapter.updateList(dao.getPackages());
    }
    swipeRefreshLayout.setRefreshing(false);
}

最佳答案

解决了!

我已将刷新代码放在 Runnable 上:
(我也改变了我的刷新)

@Override
public void onRefresh() {
    new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                if (Update.updateAll(MainActivity.this)) {
                    packages = dao.getPackages(config.getFilter());
                    packagesAux = dao.getPackages(config.getFilter());
                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            adapter.animateTo(packages);
                        }
                    });
                }
            } catch (ExecutionException e) {
                e.printStackTrace();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    swipeRefreshLayout.setRefreshing(false);
                }
            });
        }
    }).start();
}
