请帮助我在线性布局中垂直放置两个列表视图的布局。问题是如果 list1 的数据多于 list2 不可见且不可滚动，则使用 scollview 不是解决方案。

     <?xml version="1.0" encoding="utf-8"?>
     <LinearLayout  xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/backrepeat"
    android:orientation="vertical" >

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/shape_calendar_top"
        android:orientation="horizontal" >

        <ImageView
            android:id="@+id/prevMonth"
            android:layout_width="50dp"
            android:layout_height="55dp"
            android:src="@drawable/button_events_previous" >
        </ImageView>

        <TextView
            android:id="@+id/currentMonth"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_vertical"
            android:layout_weight="0.6"
            android:gravity="center_vertical|center_horizontal"
            android:text="Janauary"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:textColor="#d458b1"
            android:textStyle="bold" >
        </TextView>

        <ImageView
            android:id="@+id/nextMonth"
            android:layout_width="50dp"
            android:layout_height="55dp"
            android:src="@drawable/button_events_next" />
    </LinearLayout>


        <TextView
            android:id="@+id/direction_label"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_alignParentRight="true"
            android:layout_marginTop="10dp"
            android:background="#DA81F5"
            android:paddingLeft="5dp"
            android:paddingTop="5dp"
            android:text="PRESS RELEASES"
            android:textColor="#FFFFFF"
            android:textSize="13dip" />

        <ListView
            android:id="@+id/eventsList"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_below="@+id/direction_label"
            android:background="#ffffff" >
        </ListView>


        <TextView
            android:id="@+id/direction_label1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="10dp"
            android:background="#DA81F5"
            android:paddingLeft="5dp"
            android:paddingTop="5dp"
            android:text="SPEECHES"
            android:textColor="#FFFFFF"
            android:textSize="13dip" />

        <ListView
            android:id="@+id/eventsList1"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_below="@+id/direction_label1"
            android:background="#ffffff" >
        </ListView>


    <TextView
        android:id="@+id/empty_list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:gravity="center"
        android:text=""
        android:textAppearance="?android:attr/textAppearanceMedium" />

</LinearLayout>

如果我使用滚动视图，那么它只会为第一行包装列表视图。

请提出一些建议。

编辑：两个列表视图的代码：

            {
                arrayofWebData.add(cn);
                listAdapter = new SelectArralAdapter(getActivity(),
                        arrayofWebData);
                List_events.setAdapter(listAdapter);
            }

对于第二个 ListView，如下所示：

  if ((year == event_year) && (event_month == month))

            {
            arrayofWebDataPress.add(cn);
            listAdapter_press = new   SelectArralAdapter_Press(getActivity(),arrayofWebDataPress);
                List_events_press.setAdapter(listAdapter_press);
                i++;

            }

两个 ListViews 的数组适配器：

     class SelectArralAdapter_Press extends ArrayAdapter<PressDB> {

    private LayoutInflater inflater;

    public SelectArralAdapter_Press(Context context,
            ArrayList<PressDB> arrayofWebDataPress) {

        super(context, R.layout.speech_list_item, R.id.event_title,
                arrayofWebDataPress);
        inflater = LayoutInflater.from(context);

    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        ViewHolder_Press holder;
        if (convertView == null) {

            convertView = inflater.inflate(R.layout.speech_list_item, null);

            holder = new ViewHolder_Press(convertView);
            convertView.setTag(holder);

        } else {

            holder = (ViewHolder_Press) convertView.getTag();
        }
        holder.populateFrom(arrayofWebDataPress.get(position));

        return (convertView);
    }

}

  class ViewHolder_Press{
    public TextView event_name = null;
    public TextView event_date = null;

    public ViewHolder_Press(View row) {
        event_name = (TextView) row.findViewById(R.id.event_title);
        event_date = (TextView) row.findViewById(R.id.event_date_time);

    }

    void populateFrom(PressDB eventsMainDB) {
        event_name.setText(eventsMainDB.press_name);
        event_date.setText(eventsMainDB.press_date + " ");
    }
}

对于第二个 Adaper ：

      class SelectArralAdapter extends ArrayAdapter<SpeechDB> {

    private LayoutInflater inflater;

    public SelectArralAdapter(Context context,
            ArrayList<SpeechDB> arrayofWebData) {

        super(context, R.layout.speech_list_item, R.id.event_title,
                arrayofWebData);
        inflater = LayoutInflater.from(context);

    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        ViewHolder holder;
        if (convertView == null) {

            convertView = inflater.inflate(R.layout.speech_list_item, null);

            holder = new ViewHolder(convertView);
            convertView.setTag(holder);

        } else {

            holder = (ViewHolder) convertView.getTag();
        }
        holder.populateFrom(arrayofWebData.get(position));

        return (convertView);
    }

}

class ViewHolder {
    public TextView event_name = null;
    public TextView event_date = null;

    public ViewHolder(View row) {

        event_name = (TextView) row.findViewById(R.id.event_title);

        event_date = (TextView) row.findViewById(R.id.event_date_time);

    }

    void populateFrom(SpeechDB eventsMainDB) {
        event_name.setText(eventsMainDB.speech_name);

        event_date.setText(eventsMainDB.speech_date + " ");


    }

}

尝试这个。

如果您想使用 xml 设计，那么您必须通过使用权重（这是最可取的）或通过在dp中提供固定大小来给出修复大小。

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

    <LinearLayout

我用过：

<ScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#FFF">

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

// first linearlayout which is holding one textview and a listview
<LinearLayout
    ">      
    <TextView 
        />        
    <ListView
        android:id="@+id/failed_list"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="20dp"
        android:layout_marginRight="20dp"
        android:layout_marginTop="5dp"/>
 </LinearLayout>

// second linearlayout which is holding one textview and a listview
<LinearLayout
    ">      
    <TextView 
        />        
    <ListView
        android:id="@+id/failed_list"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="20dp"
        android:layout_marginRight="20dp"
        android:layout_marginTop="5dp"/>
 </LinearLayout>

// third linearlayout which is holding one textview and a listview
<LinearLayout
    ">      
    <TextView 
        />        
    <ListView
        android:id="@+id/failed_list"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="20dp"
        android:layout_marginRight="20dp"
        android:layout_marginTop="5dp"/>
 </LinearLayout>

// and finally i have added a button in the parent linearlayout
<Button
     />

</LinearLayout>
</ScrollView>

你可以试试这个。

尝试如下：

这是同一布局文件中多个 ListView 的解决方案。您可以将布局文件设置为以下布局，方法是为LinearLayout.

<LinearLayout android:layout_weight="1" 
                    android:layout_height="fill_parent" 
                    android:layout_width="fill_parent">

                <ListView   android:id="@+id/list1" 
                            android:layout_height="fill_parent" 
                            android:layout_width="fill_parent">

                </ListView>
    </LinearLayout>

<LinearLayout android:layout_weight="1" 
                android:layout_height="fill_parent" 
                android:layout_width="fill_parent">

            <ListView   android:id="@+id/list2" 
                        android:layout_height="fill_parent" 
                        android:layout_width="fill_parent">

            </ListView>
</LinearLayout>

Java 代码 

public class MainActivity extends Activity {
private ListView lv1 = null;
private ListView lv2 = null;
private String s1[] = {"a", "b", "c", "d", "e", "f"};
private String s2[] = {"r", "s", "t", "u", "v", "w", "x"};

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);
    lv1 = (ListView) findViewById (R.id.list1);
    lv2 = (ListView) findViewById (R.id.list2);

    lv1.setAdapter(new ArrayAdapter<String> (this, android.R.layout.simple_list_item_1, s1));
    lv2.setAdapter(new ArrayAdapter<String> (this, android.R.layout.simple_list_item_1, s2));

} 
}

有关更多详细信息，您可以参考给出相同解决方案的链接。

我希望它会帮助你。

谢谢。

你可以拿这样的东西。 

<LinearLayout>
   <ScrollView>
     <LinearLayout>
       {Your All code of controls}
     </LinearLayout>
   </ScrollView>
</LinearLayout>

或者 uo 可以<ScrollView>作为父标签。
你可以做这样的事情。根据我的知识...

我通过使用节标题并将两个列表视图组合成一个列表视图并通过节标题对它们进行分类来解决了这个问题。
