请帮助我在垂直放置在线性布局中的两个列表视图的布局。问题是,如果list1的数据多于list2的数据不可见且不可滚动,则使用scollview不是解决方案。线性布局中的两个ListViews
<?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"

<LinearLayout

android:layout_width="50dp"
android:layout_height="55dp"

</ImageView>
<TextView

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_weight="0.6"

</LinearLayout>

android:layout_height="wrap_content"

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scrollview,那么它仅包含第一行的listview。
请提出建议。

如果我用这个,什么也看不见了:(
ASMI
编辑:CODE为两名列表视图:
{
arrayofWebData.add(cn);
listAdapter = new SelectArralAdapter(getActivity(),
arrayofWebData);
List_events.setAdapter(listAdapter);
}
对于第二ListView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++;
}
两个列表视图数组适配器:
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 + " ");
}
}

哪种解决方案,你建议我试着用相对布局,它不工作 – Asmi 2013-02-20 04:38:38
你可以尝试在两个'ListView'上放置'layout_weight = 1'属性,并且两者都会采用相同的比例。请记得将'layout_height'改为'0'而不是'wrap_content'。 – Aprian 2013-02-20 04:41:19
