TableLayout里的元素为什么宽度没有占满父控件

Question

本想把手机屏幕剩下的部分用ScrollView和TableLayout占满
所以使用了LinearLayout，分别定义weight，ScrollView是0.6，TableLayout是0.4
以下是部分代码<LinearLayout 
        android:layout_width="fill_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">
        <ScrollView 
            android:id="@+id/result_view"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="0.6">
            <LinearLayout 
                android:id="@+id/linear_view"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:orientation="vertical">
                <RelativeLayout
         android:layout_width="fill_parent"
         android:layout_height="wrap_content">
     <TextView 
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:textSize="18sp"
         android:text="猜的数字"
         android:layout_alignParentLeft="true"
         android:layout_alignParentTop="true"
         />
     <TextView 
         android:textSize="18sp"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:text="A"
         android:layout_alignParentTop="true"
         android:layout_centerHorizontal="true"
         />
     <TextView 
         android:textSize="18sp"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:text="B"
         android:layout_alignParentTop="true"
         android:layout_alignParentRight="true"/>
  
     </RelativeLayout>
                
            </LinearLayout>
            
        </ScrollView>
        <TableLayout 
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="20dp"
            android:layout_weight="0.4">
            <TableRow
                android:gravity="center">
                <Button 
                    android:id="@+id/btn_0"
                    
                    android:text="0"
                    />
                <Button 
                    android:id="@+id/btn_1"
                    
                    android:text="1"
                    />
                <Button 
                    android:id="@+id/btn_2"
                    
                    android:text="2"
                    />
                <Button 
                    android:id="@+id/btn_3"
                    
                    android:text="3"
                    />
                <Button 
                    android:id="@+id/btn_4"
             
                    android:text="4"
                    />
             </TableRow>
             <TableRow
                 android:gravity="center">
                 <Button 
                    android:id="@+id/btn_5"
                    
                    android:text="5"
                    />
                 <Button 
                    android:id="@+id/btn_6"
                    
                    android:text="6"
                    />
                 <Button 
                    android:id="@+id/btn_7"
                    
                    android:text="7"
                    />
                 <Button 
                    android:id="@+id/btn_8"
                    
                    android:text="8"
                    />
                 <Button 
                    android:id="@+id/btn_9"
                    
                    android:text="9"
                    />
             </TableRow>
             
        </TableLayout>
    </LinearLayout>但是后面生成的结果不对，TableLayout两排10个button只占手机屏幕宽度的一部分
我想的是占满全手机屏幕宽度，手机屏幕高度也没有完全沾满
下面是完整的xml代码，那位大侠能否测试下，就能看到我说的情况了
在此先谢过了，中间有一部分我想实现动画效果，所以只生成了ID,并没有添加实际控件<?xml version="1.0" encoding="utf-8"?>

Answer 1

我想要的界面如下图所示
最上面3个是TextView
往下的3个是图片
再往下是ScrollView
最后是button
我所用的界面button不能如图中所示，占满手机屏幕的宽以及剩下的屏幕空间

Answer 2

你把每个Button添加android:layout_windth="fill_parents"试试

Answer 3

将以下代码中ImageView的icon1、icon2、icon3分别改成你的图片。
