上面有scrollView和Layout的SwipeRefreshLayout

Question

我有以下布局

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

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical" >
            //some views here
        </LinearLayout>

        <ScrollView
            android:layout_width="match_parent"
            android:layout_height="wrap_content" >
        <TableLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:stretchColumns="*" >
        </TableLayout>

    </LinearLayout>

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

问题是当我向下滚动表格时,我无法再次滚动,因为正在触发swipelayout.仅当表的第一个视图可见时,如何触发swiperefresh？

Answer 1

我发现,如果您更换ScrollView了android.support.v4.widget.NestedScrollView,你指望它的滚动行为会奏效.

Answer 2

自己实现SwipeRefreshLayout并以这种方式覆盖canChildScrollUp:

    @Override
public boolean canChildScrollUp() {
    if (scrollView != null)
        return scrollView.canScrollVertically(-1);

    return false;
}

只需替换ScrollView的任何子类.

Answer 3

如果你有这样的布局：

<SwipeRefreshLayout>
    <android.support.v4.widget.NestedScrollView
        android:id="@+id/your_scroll_view_id">
        <LinearLayout>
        ...
        </LinearLayout>
    </android.support.v4.widget.NestedScrollView>
</SwipeRefreshLayout>

您需要创建自己的类并以这种方式覆盖该函数：

class SwipeRefreshLayoutCustom extends SwipeRefreshLayout {
    public SwipeRefreshLayoutCustom(Context context, AttributeSet attributes) {
        super(context, attributes)
    }
    @override
    boolean canChildScrollUp() {
        return your_scroll_view_id.scrollY != 0
    }
}
