Question

我看了SO上的类似答案，但它们对我没有用。我有以下布局可能不是最佳的（请指出任何错误，因为我是一个初学者）。

<?xml version="1.0" encoding="utf-8"?>
<GridLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent" android:rowCount="3" android:columnCount="1" android:padding="0dp"
              android:background="#ebe0cf">

    <LinearLayout
            android:orientation="vertical"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" android:layout_row="0" android:layout_column="0"
            android:background="#ebe0cf" android:layout_marginTop="5dp">
        <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Book Name"
                android:id="@+id/textView" android:layout_gravity="center_horizontal" android:textSize="30dp"
                android:textStyle="bold"/>
        <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Chapter Name"
                android:id="@+id/textView1" android:textSize="13dp" android:layout_gravity="center_horizontal"
                android:layout_marginTop="-3dp"/>
    </LinearLayout>


    <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Lorem Ipsum is simply dummy text of the printing and typesetting industry.

              android:id="@+id/textView4" android:padding="5dp" android:background="#ffffff"
              android:layout_margin="10dp"
            android:scrollbars="vertical"/>

    <LinearLayout
            android:orientation="horizontal"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" android:layout_row="2" android:layout_column="0"
            android:background="#ebe0cf">
        <Button
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Prev"
                android:id="@+id/button"/>
        <Button
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Next"
                android:id="@+id/button1"/>
        <Button
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Language"
                android:id="@+id/button2"/>
    </LinearLayout>
</GridLayout>

发生的事情是，一旦TextView有足够长的文本它将按钮推离页面，我希望按钮保持在底部的位置，并让TextView开始滚动...我试着把它放在一个ScollView也是如此。

我想保持简单，所以如果可能的话我想避免使用相对布局之类的东西。

Answer 1

如果你给LinearLayout一个weightSum（任意数字），然后给它的子视图layout_weight加起来总和，它将使用这些权重作为总数的百分比。

因此，您的按钮可以是layout_weight="1"，您的ScrollView可以是layout_weight="9"。如果LinearLayout具有weightSum="10"，那么它将是90％ScrollView和10％按钮。

权重不一定是整数，你的权重可以是5.5。

哦，这非常非常重要，将子视图的layout_height（假设您的LinearLayout的方向为Vertical）设置为0dp。重量将照顾它真正的高度。
