線性佈局中的兩個ListViews

請幫助我在垂直放置在線性佈局中的兩個列表視圖的佈局。問題是，如果list1的數據多於list2的數據不可見且不可滾動，則使用scollview不是解決方案。線性佈局中的兩個ListViews

 <?xml version="1.0" encoding="utf-8"?>

    <TextView

     android:layout_height="fill_parent" 
     android:gravity="center" 
     android:text="" 
     android:textAppearance="?android:attr/textAppearanceMedium" /> 

</LinearLayout>

如果我使用scrollview，那麼它僅包含第一行的listview。

請提出建議。

編輯：CODE爲兩名列表視圖：

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

對於第二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++; 

      }

兩個列表視圖數組適配器：

 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 + " "); 
    } 
}

對於第二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 + " "); 


    } 

}

哪種解決方案，你建議我試着用相對佈局，它不工作 – Asmi 2013-02-20 04:38:38

你可以嘗試在兩個'ListView'上放置'layout_weight = 1'屬性，並且兩者都會採用相同的比例。請記得將'layout_height'改爲'0'而不是'wrap_content'。 – Aprian 2013-02-20 04:41:19

你可以採取這樣的事情。

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

或UO可以採取<ScrollView>作爲父標籤..
你可以做這樣的事情。按我的知識......

我已經使用，如：

<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>

你可以試試這個。

試試這個。

如果你想要去的XML設計，那麼你必須給固定大小，無論是通過使用重量（這是最優先）或在DP給予修復大小。

<?xml version="1.0" encoding="utf-8"?>

如果我使用這個，沒有任何顯示:( – Asmi 2013-02-20 05:09:43

現在在Listview中沒有顯示任何值，它們是空的 – Asmi 2013-02-20 05:12:08

你的意思是當你運行這個代碼，那麼你正面臨着這個問題 – 2013-02-20 05:13:05

試用如下：

這裏是相同的佈局文件中的溶液，以一個以上的ListView。您可以通過爲LinearLayout內的每個佈局提供相同的權重，將佈局文件設置爲以下佈局。

<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代碼的

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)); 

} 
}

欲瞭解更多詳細信息，您可以參考已經給出了相同的解決方案Link。

我希望它能幫助你。

謝謝。

顯示我將兩個相對佈局合併爲一個東西 – Asmi 2013-02-20 05:17:58

查看我的更新答案 – GrIsHu 2013-02-20 06:02:42

這使得屏幕分爲兩部分，一個用於1個listview，另一個用於其他one1，每個部分H大大自己的listview滾動，我可以有像整體佈局滾動而不是單獨滾動的列表視圖。因此，一旦listview1完成Listview2啓動 – Asmi 2013-02-20 06:18:03

我解決了這個問題，使用節標題並將兩個listviews結合到一個listview中，並通過Section標題的幫助對它們進行分類。
