SwipeRefreshLayout不起作用

问题描述

我正在使用支持库中的SwipeRefreshListener.我正在从AsyncTask的onPreExecute和onPostExecute调用setRefresh.但是，没有任何变化，没有动画.有什么我想念的吗?是否需要设置某些设置参数才能使其正常工作?

I'm using SwipeRefreshListener from the support libraries. I am calling setRefresh from onPreExecute and onPostExecute of my AsyncTask. However, nothing changes, there is no animation. Is there something that I'm missing? Are there certain setup parameters I need to set in order for it to work properly?

SwipeRefreshLayout:布局您只需使用此新布局来装饰可滑动内容(可能是整个布局).该视图必须是可滚动的，例如ScrollView或ListView.举一个简单的例子:

SwipeRefreshLayout: The layoutyou only need to decorate the swipable content (probable the whole layout) with this new layout. This view must be scrollable, such a ScrollView or a ListView. As a simple example:

<android.support.v4.widget.SwipeRefreshLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/swipe_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <TextView
            android:text="@string/hello_world"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="16dp"
            android:gravity="center"/>
    </ScrollView>

</android.support.v4.widget.SwipeRefreshLayout>

代码我们只需要获取布局，并分配一些颜色和侦听器即可.令人耳目一新的侦听器是一个延迟发布的处理程序.

The codeWe just need to get the layout, and assign some colours and the listener. The refreshing listener is a post delayed handler.

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

        swipeLayout = (SwipeRefreshLayout) findViewById(R.id.swipe_container);
        swipeLayout.setOnRefreshListener(this);
        swipeLayout.setColorScheme(android.R.color.holo_blue_bright, 
                android.R.color.holo_green_light, 
                android.R.color.holo_orange_light, 
                android.R.color.holo_red_light);
    }


    @Override public void onRefresh() {
        new Handler().postDelayed(new Runnable() {
            @Override public void run() {
                swipeLayout.setRefreshing(false);
            }
        }, 5000);
    }
