下面扩大滚动视图按钮 [英] buttons below expanding scrollview

问题描述

我努力要实现的布局是（我认为）pretty的简单。

The layout I try to implement is (I think) pretty simple.

一个TextView的扩展取决于里面是什么。正下方有两个按钮（确定/取消）。

One TextView expands depending on what is inside. Just below are two buttons (OK/Cancel).

我可以让按键粘在屏幕的底部，并且工作正常。不过，我想有这些按钮的正下方的TextView。 我已经尝试了很多不同的东西，但这里是我的最新布局：

I can make the buttons stick to the bottom of the screen and that works fine. But I would like to have those buttons just below the TextView. I have tried a lot of different things, but here is my latest layout :

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"
        >
    <ScrollView android:id="@+id/Scroll"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:layout_alignParentTop="true"
            >
        <TextView
                android:id="@+id/Text"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                />
    </ScrollView>
    <RelativeLayout android:id="@+id/buttons"
                    android:layout_height="fill_parent"
                    android:layout_width="fill_parent"
                    android:layout_below="@+id/Scroll"
                    android:layout_above="@+id/bottom"
            >
        <LinearLayout
                android:orientation="horizontal"
                android:layout_height="wrap_content"
                android:layout_width="fill_parent">
            <Button android:id="@+id/ButtonOK"
                    android:layout_height="80dp"
                    android:layout_width="fill_parent"
                    android:text="OK"
                    android:layout_weight="1"/>
            <Button android:id="@+id/ButtonCancel"
                    android:layout_height="80dp"
                    android:layout_width="fill_parent"
                    android:text="Cancel"
                    android:layout_weight="1"/>
        </LinearLayout>
    </RelativeLayout>
    <LinearLayout android:id="@+id/bottom"
                  android:layout_height="0px"
                  android:layout_width="fill_parent"
                  android:layout_alignParentBottom="true"/>
</RelativeLayout>

在最后空的LinearLayout是（不成功）试图prevent认为过去在屏幕的底部...

The empty linearlayout at the end is an (unsuccessful) attempt to prevent the view to extend past the bottom of the screen...

在一切我试过了，无论是按钮在屏幕的底部，或还要再过去，当TextView的太大了。

In everything I tried, either the buttons are at the bottom of the screen or they would go past it when the TextView is too big.

下面是什么，我试图做一个素描：

Here is a sketch of what I am trying to do :

推荐答案

时的目标只是有一个滚动区域，占用了整个页面减去在底部采取了一些按钮的数量？

Is the goal just to have a scrollable area that takes up the entire page minus the amount taken up by some buttons at the bottom?

在这种情况下，使用的LinearLayout 在外部层面，利用权重：

In that case, use a LinearLayout at the outer level and make use of weights:

<LinearLayout 
   android:layout_height="wrap_content" 
   orientation="vertical"...>
   <ScrollView
      android:layout_height="0"
      android:layout_weight="1"
      .../>
   <LayoutWithButtons
      android:layout_height="wrap_content"
      ..../>
</LinearLayout>
