如何使用使用網格視圖和滾動和按鈕進行

Question

我'試圖在我的項目一個XML文件，該文件包含實現：一個TextView，GridView控件和一個返回按鈕，但這裏的代碼：

<?xml version="1.0" encoding="UTF-8"?> 
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:mask="http://schemas.android.com/apk/res/br.com.example.sgm" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:background="@color/Black" 
    android:screenOrientation="portrait" > 



    <TextView 
    android:id="@+id/TextView01" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_marginBottom="20dp" 
    android:layout_marginTop="10dp" 
    android:text="Código     Data" 
    android:textAppearance="?android:attr/textAppearanceLarge" 
    android:textColor="@color/LSGray" /> 






    <Button 
    android:id="@+id/button1" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_marginTop="410dp" 
    android:onClick="bvoltar" 
    android:text="  Voltar  " 
    android:textColor="@color/Snow" /> 

    <ScrollView 
    android:id="@+id/scrollView1" 
    android:layout_width="fill_parent" 
    android:layout_height="350dp" 
    android:layout_centerHorizontal="true" 
    android:layout_marginTop="50dp" > 

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



    <GridView 
    android:id="@+id/gridview" 
    android:layout_width="match_parent" 
    android:layout_height="345dp" 
    android:numColumns="1" > 

    </GridView> 

    </LinearLayout> 
    ScrollView> 

</RelativeLayout> 

這應該在頂部是一個小文本，一個網格顯示一個數據庫表中的字段，一個按鈕退出，在網格內滾動......但是當我運行該項目並轉到此屏幕時，滾動不工作，網格加載和顯示entrys，但如果嘗試移動滾動這關閉我的apk，任何人都知道如何修復它？

這裏的適配器：

public class DataAdapter extends BaseAdapter 

{ 

    Context mContext; 


//  
//  private String [] codigo = new String[100]; 
//  private String [] data = new String[100]; 

    private LayoutInflater mInflater; 

    public int cont; 

    public DataAdapter(Context c) 

    { 

     mContext=c; 

     mInflater = LayoutInflater.from(c); 

    } 

    public int getCount() 

    { 
     PersistenceHelper per = PersistenceHelper.getInstance(mContext); 
     List<Ocorrencia> lOco; 
      lOco = per.listarOcorrencia(); 
     return lOco.size(); 

    } 

    public Object getItem(int position) 

    { 

     return position; 

    } 

    public long getItemId(int position) 

    { 

     return position; 

    } 

    public View getView(int position, View convertView, ViewGroup parent) 

    { 

     ViewHolder holder=null; 

     if(convertView==null) 

     { 

       convertView = mInflater.inflate(R.layout.customgrid, 
                   parent,false); 

       holder = new ViewHolder(); 

       holder.txtCodigo=(TextView)convertView.findViewById(R.id.txtCodigo); 

       holder.txtCodigo.setPadding(10, 10, 10 , 10); 

       holder.txtData=(TextView)convertView.findViewById(R.id.txtData); 

       holder.txtData.setPadding(10, 10, 10, 10); 

       if(position==0) 

       {        

         convertView.setTag(holder); 

       } 

     } 

     else 

     { 

       holder = (ViewHolder) convertView.getTag(); 

     } 
     PersistenceHelper per = PersistenceHelper.getInstance(mContext); 

     List<Ocorrencia> lOco = per.listarOcorrencia(); 
     setCont(lOco.size()); 

     String [] codigo = new String[getCont()]; 
     String [] data = new String[getCont()]; 

     for(int x=0; x<getCont(); x++){ 
      codigo[x] = lOco.get(x).getCodigo(); 
      data[x] = lOco.get(x).getData(); 
      } 

     holder.txtCodigo.setText(codigo[position]); 

     holder.txtData.setText(data[position]); 

     getCount(); 

     return convertView; 


    } 

    static class ViewHolder 

    {   

     TextView txtCodigo;   

     TextView txtData;    

    } 

public int getCont() { 
    return cont; 
} 

public void setCont(int cont) { 
    this.cont = cont; 
} 



} 

，如果是必要的......

<LinearLayout 

xmlns:android="http://schemas.android.com/apk/res/android" 

android:layout_width="fill_parent" 

android:layout_height="fill_parent" 

android:orientation="vertical"> 

<TableLayout android:id="@+id/TableLayout01" 

      android:layout_height="wrap_content" 

      android:layout_width="fill_parent"> 


    <TableRow 
     android:id="@+id/TableRow01" 
     android:layout_width="wrap_content" 
     android:layout_height="fill_parent" > 




    <TextView 
     android:id="@+id/txtCodigo" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_gravity="center_horizontal" 
     android:text="Codigo" 
     android:textColor="@color/LSGray" /> 


    <TextView 
     android:id="@+id/txtData" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_gravity="center_horizontal" 
     android:text="     Data" 
     android:textColor="@color/Snow" /> 

    </TableRow> 

</TableLayout> 

</LinearLayout> 

不會對logcat的一個原因這個錯誤的代碼我有變化的東西，但問題是，因爲是不是更接近，但是，這只是從數據庫的entrys顯示一小塊，並沒有顯示所有的entrys，我不能改變gridview填充父寬度和高度，我怎麼可以把網格增加大小每個新的entrys ？

UPDATE 1
當我通過MM-BB答案刪除滾動型
logcat的錯誤：

Answer 1

1的GridView不需要滾動視圖這是當你在滾動視圖使用gridview的日食顯示警告

The vertically scrolling ScrollView should not contain another vertically scrolling widget (GridView) 

2變ScrollView>至</ScrollView>
