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

最好的代码

 <android.support.v4.widget.NestedScrollView
    android:id="@+id/scrollView1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_above="@+id/btmlyt"
    android:layout_below="@+id/deshead_tv">

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

    <TextView
        android:id="@+id/des_tv"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_above="@+id/btmlyt"
        android:background="@android:color/white"
        android:paddingLeft="3dp"
        android:paddingRight="3dp"
        android:scrollbars="vertical"
        android:paddingTop="3dp"
        android:text="description"
        android:textColor="@android:color/black"
        android:textSize="18sp" />
    </LinearLayout>

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

这对我有用(link1, link2):

You Create Custom ListView Which is non Scrollable public class NonScrollListView extends ListView { public NonScrollListView(Context context) { super(context); } public NonScrollListView(Context context, AttributeSet attrs) { super(context, attrs); } public NonScrollListView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } @Override public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { int heightMeasureSpec_custom = View.MeasureSpec.makeMeasureSpec( Integer.MAX_VALUE >> 2, View.MeasureSpec.AT_MOST); super.onMeasure(widthMeasureSpec, heightMeasureSpec_custom); ViewGroup.LayoutParams params = getLayoutParams(); params.height = getMeasuredHeight(); } } In Your Layout File <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:fillViewport="true"> <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" > <!-- com.Example Changed with your Package name --> <com.thedeveloperworldisyours.view.NonScrollListView android:id="@+id/lv_nonscroll_list" android:layout_width="match_parent" android:layout_height="wrap_content" > </com.thedeveloperworldisyours.view.NonScrollListView> <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_below="@+id/lv_nonscroll_list" > <!-- Your another layout in scroll view --> </RelativeLayout> </RelativeLayout> </ScrollView> Create a object of your customListview instead of ListView like : NonScrollListView non_scroll_list = (NonScrollListView) findViewById(R.id.lv_nonscroll_list);

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。

在xml:

<com.example.util.NestedListView
                    android:layout_marginTop="10dp"
                    android:id="@+id/listview"
                    android:layout_width="fill_parent"
                    android:layout_height="fill_parent"
                    android:divider="@null"

                    android:layout_below="@+id/rl_delivery_type" >
                </com.example.util.NestedListView>

在Java中:

public class NestedListView extends ListView implements View.OnTouchListener, AbsListView.OnScrollListener {

    private int listViewTouchAction;
    private static final int MAXIMUM_LIST_ITEMS_VIEWABLE = 99;

    public NestedListView(Context context, AttributeSet attrs) {
        super(context, attrs);
        listViewTouchAction = -1;
        setOnScrollListener(this);
        setOnTouchListener(this);
    }

    @Override
    public void onScroll(AbsListView view, int firstVisibleItem,
                         int visibleItemCount, int totalItemCount) {
        if (getAdapter() != null && getAdapter().getCount() > MAXIMUM_LIST_ITEMS_VIEWABLE) {
            if (listViewTouchAction == MotionEvent.ACTION_MOVE) {
                scrollBy(0, -1);
            }
        }
    }

    @Override
    public void onScrollStateChanged(AbsListView view, int scrollState) {
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);

        int newHeight = 0;
        final int heightMode = MeasureSpec.getMode(heightMeasureSpec);
        int heightSize = MeasureSpec.getSize(heightMeasureSpec);
        if (heightMode != MeasureSpec.EXACTLY) {
            ListAdapter listAdapter = getAdapter();
            if (listAdapter != null && !listAdapter.isEmpty()) {
                int listPosition = 0;
                for (listPosition = 0; listPosition < listAdapter.getCount()
                        && listPosition < MAXIMUM_LIST_ITEMS_VIEWABLE; listPosition++) {
                    View listItem = listAdapter.getView(listPosition, null, this);
                    //now it will not throw a NPE if listItem is a ViewGroup instance
                    if (listItem instanceof ViewGroup) {
                        listItem.setLayoutParams(new LayoutParams(
                                LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
                    }
                    listItem.measure(widthMeasureSpec, heightMeasureSpec);
                    newHeight += listItem.getMeasuredHeight();
                }
                newHeight += getDividerHeight() * listPosition;
            }
            if ((heightMode == MeasureSpec.AT_MOST) && (newHeight > heightSize)) {
                if (newHeight > heightSize) {
                    newHeight = heightSize;
                }
            }
        } else {
            newHeight = getMeasuredHeight();
        }
        setMeasuredDimension(getMeasuredWidth(), newHeight);
    }

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if (getAdapter() != null && getAdapter().getCount() > MAXIMUM_LIST_ITEMS_VIEWABLE) {
            if (listViewTouchAction == MotionEvent.ACTION_MOVE) {
                scrollBy(0, 1);
            }
        }
        return false;
    }
}

我的要求是在ScrollView中包含大小相等的项的ListView。我尝试了这里列出的其他一些解决方案,似乎没有一个能正确地调整ListView的大小(要么空间太小,要么太多)。以下是对我有效的方法:

    public static void expandListViewHeight(ListView listView) {
    ListAdapter listAdapter = listView.getAdapter();
    if (listAdapter == null)
        return;

    ViewGroup.LayoutParams params = listView.getLayoutParams();
    listView.measure(0, 0);
    params.height = listView.getMeasuredHeight() * listAdapter.getCount() + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
    listView.setLayoutParams(params);
}

希望这能帮助到一些人。
