android - Android:CollapsingToolbarLayout和SwipeRefreshLayout卡住

我将CollapsingToolbarLayout，RecyclerView和SwipeRefreshLayout一起使用:

代码:

    swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipe_container);
    swipeRefreshLayout.setOnRefreshListener(this);

当折叠的工具栏布局为完全展开后的和滚动 View (recyclerview)在顶部上时，如何仅允许滑动刷新 Action 仅？类似于Google+或Inbox应用程序中的行为。

最佳答案

更新:该问题已在最新版本的支持库(23.1.1+)中得到解决。如果您使用的支持库版本较旧，请升级或继续阅读。

如果您使用的支持库版本较旧，则将偏移量更改侦听器添加到AppBarLayout中，以启用或禁用滑动以相应刷新布局。此处提供其他代码:

https://gist.github.com/blackcj/001a90c7775765ad5212

相关更改:

public class MainActivity extends AppCompatActivity implements AppBarLayout.OnOffsetChangedListener {
    ...

    private AppBarLayout appBarLayout;
    private SwipeRefreshLayout mSwipeRefreshLayout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ...
        mSwipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.contentView);
        appBarLayout = (AppBarLayout) findViewById(R.id.appBarLayout);

    }

    @Override
    public void onOffsetChanged(AppBarLayout appBarLayout, int i) {
        //The Refresh must be only active when the offset is zero :
        mSwipeRefreshLayout.setEnabled(i == 0);
    }

    @Override
    protected void onResume() {
        super.onResume();
        appBarLayout.addOnOffsetChangedListener(this);
    }

    @Override
    protected void onPause() {
        super.onPause();
        appBarLayout.removeOnOffsetChangedListener(this);
    }
}
