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

我知道已经很长时间了,但我也有这个问题,尝试了这个解决方案,它是有效的。所以我想这对其他人也有帮助。

我添加android:fillViewport="true"的布局xml为scrollView。 总的来说,ScrollView是这样的。

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/scrollView6" 
    android:fillViewport="true">

这对我来说就像魔法一样。 位于ScrollView内部的ListView再次扩展到它的大小。

下面是ScrollView和ListView的完整示例代码。

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/scrollView6" android:fillViewport="true">
    <LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        ....
        <ListView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:id="@+id/lv_transList" android:layout_gravity="top"
            android:layout_marginTop="5dp"/>
        ....
    </LinearLayout>
</ScrollView>

其他回答

答案很简单,我很惊讶这里还没有答案。

在列表本身上使用标题视图或/和页脚视图。 不要把ScrollView和ListView或任何可以滚动的东西混在一起。它意味着与页眉和页脚一起使用:)

从本质上讲,将ListView上面的所有内容放在另一个.xml文件中作为布局,然后在代码中扩展它,并将其作为头视图添加到列表中。

i.e.

View header = getLayoutInflater().inflate(R.layout.header, null);
View footer = getLayoutInflater().inflate(R.layout.footer, null);
listView.addHeaderView(header);
listView.addFooterView(footer);

It is not possible to use Scroll-view inside List-view as List-view already has scrolling property. To use list-view inside Scroll-view you can follow these steps which worked for me : 1) Create NonScrollListView java file that disable the default scrolling property of list-view. and code is below package your-package-structure; import android.content.Context; import android.util.AttributeSet; import android.view.ViewGroup; import android.widget.ListView; 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 = MeasureSpec.makeMeasureSpec( Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST); super.onMeasure(widthMeasureSpec, heightMeasureSpec_custom); ViewGroup.LayoutParams params = getLayoutParams(); params.height = getMeasuredHeight(); } } 2) Now create xml file which which has NestedScrollView and inside this use NonScrollListView for listing your items. This will make your entire screen to scroll with all the views. <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_weight="1" android:orientation="vertical"> <ViewFlipper android:id="@+id/v_flipper" android:layout_width="match_parent" android:layout_height="130dp"> </ViewFlipper> <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:text="SHOP" android:textSize="15dp" android:textStyle="bold" android:gravity="center" android:padding="5dp" android:layout_marginTop="15dp" android:layout_marginBottom="5dp" android:layout_marginLeft="8dp" android:layout_marginRight="8dp"/> <View android:layout_width="match_parent" android:layout_height="1dp" android:layout_marginBottom="8dp" android:layout_marginLeft="8dp" android:layout_marginRight="8dp" android:background="#ddd"/> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" android:layout_weight="1" > <com.abc.xyz.NonScrollListView android:id="@+id/listview" android:divider="@null" android:layout_width="match_parent" android:layout_marginBottom="10dp" android:layout_height="match_parent" android:padding="8dp"> </com.abc.xyz.NonScrollListView> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="bottom"> <include layout="@layout/footer" /> </LinearLayout> </LinearLayout> 3) Now in java class i.e, home.java define NonScrollListView instead of Listview. package comabc.xyz.landscapeapp; import android.content.Intent; import android.support.annotation.NonNull; import android.support.annotation.Nullable; import android.support.v4.app.Fragment; import android.os.Bundle; import android.support.v4.app.FragmentTransaction; import android.util.Log; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.AdapterView; import android.widget.Button; import android.widget.ImageView; import android.widget.ListView; import android.widget.Toast; import android.widget.Toolbar; import android.widget.ViewFlipper; public class home extends Fragment { int pos = 0; ViewFlipper v_flipper; @Nullable @Override public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { View view = inflater.inflate(R.layout.activity_home, container, false); return view; } @Override public void onViewCreated(@NonNull final View view, @Nullable Bundle savedInstanceState) { NonScrollListView listView = (NonScrollListView) view.findViewById(R.id.listview); customAdapter customAdapter = new customAdapter(getActivity()); listView.setAdapter(customAdapter); listView.setFocusable(false); customAdapter.notifyDataSetChanged(); listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Log.d("listview click", "onItemClick: "); /* FragmentTransaction fr = getFragmentManager().beginTransaction().replace(R.id.fragment_container, new productdisplay()); fr.putExtra("Position", position); fr.addToBackStack("tag"); fr.commit();*/ Intent intent = new Intent(getActivity(), productdisplay.class); intent.putExtra("Position", position); startActivity(intent); } }); //image slider int images[] = {R.drawable.slide1, R.drawable.slide2, R.drawable.slide3}; v_flipper = view.findViewById(R.id.v_flipper); for (int image : images) { flipperImages(image); } } private void flipperImages(int image) { ImageView imageView = new ImageView(getActivity()); imageView.setBackgroundResource(image); v_flipper.addView(imageView); v_flipper.setFlipInterval(4000); v_flipper.setAutoStart(true); v_flipper.setInAnimation(getActivity(), android.R.anim.slide_in_left); v_flipper.setOutAnimation(getActivity(), android.R.anim.slide_out_right); } } Note: I used Fragments here.

我有一个类似于原始海报的问题——如何让列表视图在滚动视图中滚动——这个答案解决了我的问题。 禁止滚动包含在ScrollView中的ListView

我没有调用新的片段到现有的布局或类似的东西,就像OP所做的那样,所以我的代码看起来像这样:

<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" >


    <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/my_listView"
       android:layout_width="match_parent"
       android:layout_height="wrap_content">
   </ListView>

</LinearLayout>

</ScrollView>

基本上我要做的是在我调用它之前检查listview的长度,当我调用它时,我把它变成那个长度。在你的java类中使用这个函数:

public static void justifyListViewHeightBasedOnChildren (ListView listView) {

    ListAdapter adapter = listView.getAdapter();

    if (adapter == null) {
        return;
    }
    ViewGroup vg = listView;
    int totalHeight = 0;
    for (int i = 0; i < adapter.getCount(); i++) {
        View listItem = adapter.getView(i, null, vg);
        listItem.measure(0, 0);
        totalHeight += listItem.getMeasuredHeight();
    }

    ViewGroup.LayoutParams par = listView.getLayoutParams();
    par.height = totalHeight + (listView.getDividerHeight() * (adapter.getCount() - 1));
    listView.setLayoutParams(par);
    listView.requestLayout();
}

然后像这样调用函数:

justifyListViewHeightBasedOnChildren(listView);

结果是一个没有滚动条的列表视图,显示整个列表视图的长度,它与滚动视图的滚动条一起滚动。

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;
}
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;
}
});
