tablelayout高度问题


====================问题描述====================
我想让tablelayout里面的所有组件的高度加起来刚好占满屏幕,应该怎么设置?
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"

    </TableRow>

</TableLayout>
目前效果是这样

====================解决方案1====================
修改TableRow的layout_height,增加layout_weight:
    <TableRow        android:layout_width="match_parent"        android:layout_height="0dp"        android:layout_weight="1">


根据需要修改TableRow中的控件的layout_height:
android:layout_height="match_parent"


修改后的xml:
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"android:textSize="50sp" >    <TableRow        android:layout_width="match_parent"        android:layout_height="0dp"        android:layout_weight="1" >        <EditText            android:id="@+id/result"            android:layout_width="match_parent"            android:layout_height="60dp"            android:background="@drawable/result_bg"            android:editable="false"            android:layout_span="4"             android:gravity="right|center_vertical"            android:layout_margin="10dp"            android:layout_weight="1" ><requestFocus />        </EditText>    </TableRow>    <TableRow        android:id="@+id/tableRow2"        android:layout_width="match_parent"        android:layout_height="0dp"        android:layout_weight="1" >        <Button            android:id="@+id/delete"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:layout_span="2"            android:text="del"             android:layout_weight="1" />        <Button            android:id="@+id/equal"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:layout_span="2"            android:text="="            android:layout_weight="1" />    </TableRow>      <TableRow        android:id="@+id/tableRow3"        android:layout_width="match_parent"        android:layout_height="0dp"        android:layout_weight="1" >        <Button            android:id="@+id/number1"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:text="1"            android:layout_weight="1" />        <Button            android:id="@+id/number2"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:text="2"            android:layout_weight="1" />        <Button            android:id="@+id/number3"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:text="3"            android:layout_weight="1" />        <Button            android:id="@+id/add"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:text="+"            android:layout_weight="1" />    </TableRow>        <TableRow        android:id="@+id/tableRow4"        android:layout_width="match_parent"        android:layout_height="0dp"        android:layout_weight="1" >        <Button            android:id="@+id/number4"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:text="4"            android:layout_weight="1" />        <Button            android:id="@+id/number5"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:text="5"            android:layout_weight="1" />        <Button            android:id="@+id/number6"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:text="6"            android:layout_weight="1" />        <Button            android:id="@+id/minus"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:text="-"            android:layout_weight="1" />    </TableRow>        <TableRow        android:id="@+id/tableRow5"        android:layout_width="match_parent"        android:layout_height="0dp"        android:layout_weight="1" >        <Button            android:id="@+id/number7"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:text="7"            android:layout_weight="1" />        <Button            android:id="@+id/number8"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:text="8"            android:layout_weight="1" />        <Button            android:id="@+id/number9"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:text="9"            android:layout_weight="1" />        <Button            android:id="@+id/multiply"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:text="*"            android:layout_weight="1" />    </TableRow>        <TableRow        android:id="@+id/tableRow6"        android:layout_width="match_parent"        android:layout_height="0dp"        android:layout_weight="1" >        <Button            android:id="@+id/ac"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:text="ac"            android:layout_weight="1" />        <Button            android:id="@
