线性布局中的两个ListView

Question

PLease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拥有的数据多于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，那么它仅包装第一行的列表视图。

请提出建议。

编辑：两个列表的代码：

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

对于第二个ListView，它如下：

  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 + " ");


    }

}

试试这个。

如果您想使用xml设计，则必须使用权重（这是最优选的）或通过在 dp中提供修复大小来提供修复大小

Answer 2

你可以采取这样的方式。

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

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

Answer 3

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。

Answer 4

试试如下：

以下是同一布局文件中多个ListView的解决方案。您可以通过为LinearLayout内的每个布局提供相等的权重，将布局文件设置为以下布局。

<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));

} 
}

我希望它会对你有所帮助。

我通过使用节标题并将两个列表视图合并到一个列表视图中并通过节标题的帮助对它们进行分类来解决了这个问题。
