============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"

            android:text="/"
            android:layout_weight="1" />

    </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:text="del" 

            android:layout_weight="1" />



        <Button

            android:id="@+id/equal"

            android:layout_width="match_parent"
