我有一个android布局,其中有一个带有许多元素的scrollView。在scrollView的底部,我有一个listView,然后由适配器填充。

我遇到的问题是,android是排除listView从scrollView作为scrollView已经有一个可滚动的功能。我希望listView和内容一样长,并且主滚动视图是可滚动的。

我怎样才能实现这种行为呢?

这是我的主要布局:

<ScrollView
    android:id="@+id/scrollView1"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="2"
    android:fillViewport="true"
    android:gravity="top" >

    <LinearLayout
        android:id="@+id/foodItemActvity_linearLayout_fragments"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >
    </LinearLayout>

</ScrollView>

然后,我以编程方式将我的组件添加到linearlayour的id: foodItemActvity_linearLayout_fragments。下面是加载到线性布局中的一个视图。就是这个给我的卷轴带来了麻烦。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <TextView
       android:id="@+id/fragment_dds_review_textView_label"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:text="Reviews:"
       android:textAppearance="?android:attr/textAppearanceMedium" />

   <ListView
       android:id="@+id/fragment_dds_review_listView"
       android:layout_width="match_parent"
       android:layout_height="wrap_content">
   </ListView>
</LinearLayout>

我的适配器然后填充这个列表视图。

当我点击主scrollView时,这是一个来自android层级查看器的图像:

如您所见,它排除了评论列表视图。

我应该能够向下滚动页面,看到8个评论,但它只显示了这3个,我可以滚动评论所在的一小部分。我想要一个全局页面滚动

经过大量的研发后完成:

Fragment_one.xml应该是这样的:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/scrollViewParent"
    android:orientation="vertical" >

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

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="400dip" >

            <ListView
                android:id="@+id/listView"
                android:layout_width="match_parent"
                android:layout_height="match_parent" />

            <View
                android:id="@+id/customView"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:background="@android:color/transparent" />
        </RelativeLayout>

        <!-- Your other elements are here -->

    </LinearLayout>

</ScrollView>

FragmentOne.java的Java类如下所示:

private ListView listView;
private View customView

onCreateView

listView = (ListView) rootView.findViewById(R.id.listView);
scrollViewParent = (ScrollView)rootView.findViewById(R.id.scrollViewParent);
customView = (View)rootView.findViewById(R.id.customView);

customView.setOnTouchListener(new View.OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {
                int action = event.getAction();
                switch (action) {
                    case MotionEvent.ACTION_DOWN:
                        // Disallow ScrollView to intercept touch events.
                        scrollViewParent.requestDisallowInterceptTouchEvent(true);
                        // Disable touch on transparent view
                        return false;

                    case MotionEvent.ACTION_UP:
                        // Allow ScrollView to intercept touch events.
                        scrollViewParent.requestDisallowInterceptTouchEvent(false);
                        return true;

                    case MotionEvent.ACTION_MOVE:
                        scrollViewParent.requestDisallowInterceptTouchEvent(true);
                        return false;

                    default:
                        return true;
                }
            }
        });

其他回答

I'll leave it here in case anyone will face the same issue. I had to put a ListView inside a ScrollView. ListView with header was not an option by a number of reasons. Neither was an option to use LinearLayout instead of ListView. So I followed the accepted solution, but it didn't work because items in the list had complex layout with multiple rows and each listview item was of variable height. Height was measured not properly. The solution was to measure each item inside ListView Adapter's getView() method.

@Override
public View getView(int position, View view, ViewGroup parent) {
    ViewHolder holder;
    if (view == null) {
        . . .
        view.setTag(holder);
    } else holder = (ViewHolder)view.getTag();
    . . .

    // measure ListView item (to solve 'ListView inside ScrollView' problem)
    view.measure(View.MeasureSpec.makeMeasureSpec(
                    View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED),
            View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));
    return view;
}

如果你想在ScrollView中显示listView中的所有项,请使用这段代码

val params: ViewGroup.LayoutParams = listView!!.layoutParams
params.height = useitemsList.size * 200 //add static height 
listView!!.layoutParams = params
listView!!.requestLayout()
listView.setOnTouchListener(new View.OnTouchListener() {

@Override
public boolean onTouch(View v, MotionEvent event) {
    scrollView.requestDisallowInterceptTouchEvent(true);

    int action = event.getActionMasked();

    switch (action) {
        case MotionEvent.ACTION_UP:
            scrollView.requestDisallowInterceptTouchEvent(false);
            break;
    }

    return false;
}
});

千万不要把ListView放在ScrollView里面!你可以在谷歌上找到关于这个主题的更多信息。在你的例子中,使用LinearLayout代替ListView并以编程方式添加元素。

你可以通过添加android:fillViewport="true"到你的ScrollView解决这个问题。

<ScrollView
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:background="@color/white"
      android:fillViewport="true"
      android:scrollbars="vertical">

<ListView
      android:id="@+id/statusList"
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"
      android:animationCache="false"
      android:divider="@null"
      android:scrollingCache="false"
      android:smoothScrollbar="true" />

</ScrollView>

在使用该属性之前,列表视图中只有一个子视图是可见的。使用后,list的所有行或子元素都是可见的。
