如何从听触摸禁用pullToRefreshScrollView [英] How to disable pullToRefreshScrollView from listening to touch

问题描述

我使用由克里斯·巴内斯提供pullToRefreshLibrary。我的GridView这是containg数据的完整列表。我试图pullToRefreshGridViewActivity，但它太慢了，所以我试图用pullToRefreshScrollViewActivity在我的GridView控件来处理它。问题是，当我这样做，滚动视图处理所有触摸事件，我不能轻扫GridView控件。我需要将其锁定，并通过润色GridView控件。
这里是我的xml：

I am using pullToRefreshLibrary provided by Chris Banes. I have gridView which is containg whole list of data. I tried pullToRefreshGridViewActivity but it was too slow so I am trying to use pullToRefreshScrollViewActivity over my gridView to handle it. The problem is that when I do so, scrollView is handling all touch events and I cannot swipe over gridView. I need to lock it and pass touches to gridView. here is my xml :

<com.handmark.pulltorefresh.library.PullToRefreshScrollView
        xmlns:ptr="http://schemas.android.com/apk/res-auto"
        android:id="@+id/pull_refresh_scrollview"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        ptr:ptrAnimationStyle="flip" >

        <com.asd.android.dda.ui.controls.ExpandableGridView
            android:id="@+id/gridview"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:clipToPadding="false"
            android:drawSelectorOnTop="true"
            android:fadingEdge="none"
            android:gravity="top"
            android:horizontalSpacing="@dimen/image_grid_hspacing"
            android:listSelector="@drawable/selector_shadow"
            android:numColumns="@integer/grid_num_cols"
            android:paddingBottom="50dp"
            android:scrollbarAlwaysDrawVerticalTrack="false"
            android:scrollbars="none"
            android:scrollingCache="true"
            android:smoothScrollbar="false"
            android:stretchMode="columnWidth"
            android:verticalSpacing="@dimen/image_grid_vspacing"
            android:visibility="visible" />
    </com.handmark.pulltorefresh.library.PullToRefreshScrollView>

我试图用滚动视图锁定：

I tried to lock scrollView with :

mScrollView.requestDisallowInterceptTouchEvent(true);
gridView.requestDisallowInterceptTouchEvent(true);

mScrollView.setOnTouchListener(new OnTouchListener(){ 
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        return false; 
    }
});
mScrollView.setOnTouchListener(null);

但是，这些工作。我不能在这里使用自定义的滚动型覆盖onInterceptTouchEvent。

But none of these work. And I can't use here custom ScrollView to override onInterceptTouchEvent.

推荐答案

一个黑客可以使用被打开库，进入 PullToRefreshBase.java 并删除最后 onInterceptTouchEvent >。然后，您可以使用自定义滚动型。

One hack you can use is to open the library, go into PullToRefreshBase.java and remove final from methods like onInterceptTouchEvent. You can then use a custom ScrollView.
