Question

我正在尝试放置两个组件。第一个（Edittext）应该扩展到下一个组件（提交按钮）。我该怎么做呢？我的XML如下...... 问题是Edittext扩展为填充屏幕并隐藏按钮：

<?xml version="1.0" encoding="utf-8"?>

<EditText
            android:id="@+id/etFeedBackText"
            android:hint="What do you think of this app? Any comments or suggestions?"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentTop="true"
            android:layout_alignBottom="@id/btnFeedBackSubmit"              
            >       
</EditText>

<Button
    android:id="@+id/btnFeedBackSubmit"
    android:text="Submit"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_below="@id/etFeedBackText"
    android:layout_alignParentBottom="true"
    >

Answer 1

将Button声明放在EditText上方，并在EditText属性中设置： android:layout_above="@id/btnFeedBackSubmit"

Answer 2

删除此行

 android:layout_alignBottom="@id/btnFeedBackSubmit"

Answer 3

试试这个

<EditText
            android:id="@+id/etFeedBackText"
            android:hint="What do you think of this app? Any comments or suggestions?"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_above="@id/btnFeedBackSubmit"              
            >       
</EditText>

<Button
    android:id="@+id/btnFeedBackSubmit"
    android:text="Submit"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    >
