如何拉伸布局以填充屏幕？

Question

我有这样简单的布局:(这是邮件)

<ScrollView android:layout_height="0dp" android:layout_width="fill_parent" android:layout_weight="1" android:background="@color/red_start">

        <LinearLayout android:layout_height="fill_parent" android:layout_width="fill_parent" android:orientation="vertical" android:background="@color/blue_start">

            <TextView style="@style/MyTextViewLabel" android:text="From" android:layout_marginTop="5dp"/>

            <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@drawable/shape_white_rounded">
                <TextView style="@style/MyTextViewLabel.Black" android:id="@+id/tv_sender" />
            </LinearLayout>

            <TextView style="@style/MyTextViewLabel" android:text="Subject" android:layout_marginTop="5dp"/>

            <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@drawable/shape_white_rounded">
                <TextView style="@style/MyTextViewLabel.Black" android:id="@+id/tv_subject" />
            </LinearLayout>

            <TextView style="@style/MyTextViewLabel" android:text="Body" android:layout_marginTop="5dp"/>

            <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@drawable/shape_white_rounded">
                <TextView style="@style/MyTextViewLabel.Black" android:id="@+id/tv_body" />
            </LinearLayout>

        </LinearLayout>

    </ScrollView>

由于某种原因,LinearLayout不会像我期望的那样填充ScrollView.基本上,我想让tv_body填充屏幕,如果有更多文本 - 它应该是可滚动的.现在它看起来像这样.我添加颜色来说明ScrollView拉伸但LinearLayout没有..

尝试添加

android:fillViewport="true"

在你的ScrollView中.
