android – 线性布局中的两个ListView

2019年8月4日 132次阅读

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"

    <LinearLayout

        android:layout_height="wrap_content"
        android:background="@drawable/shape_calendar_top"
        android:orientation="horizontal" >

        <ImageView
            android:id="@+id/prevMonth"

            android:layout_height="55dp"
            android:src="@drawable/button_events_previous" >
        </ImageView>

        <TextView

            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: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,那么它只包含第一行的listview.

请提出建议.

如果我使用它,没有显示任何内容:(

ASMI

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ListView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 + " ");


    }

}

最佳答案 试试这个.

如果你想使用xml设计,那么你必须通过使用权重(这是最优选的)或通过在dp中给出修复大小来给出修复大小.
