Android的布局：父宽度的一半 [英] Android Layout: width half of parent

问题描述

我有一个非常简单的布局，我不能让它看起来像我想要的。这是一个按钮和一个开关一个LinearLayout中。我希望他们能够显示一个在另一个之上，但我想它们的宽度是父布局的一半。

I have a very simple layout that I can't make it looks like I want. It's a LinearLayout with a button and a Switch. I want them to show one above the other, but I want their width to be the half of the parent layout.

|--LinearLayout---------|
|                       |
| -----------           |
||   Switch  |          |
| -----------           |
| -----------           |
||   button  |          |
| -----------           |
 ------------------------

我一直在寻找其他类似的回答在左右，但我无法找到一个解决方案，为我工作。这是我试过至今：

I've been looking at other similar answer in SO but I couldn't find a solution that works for me. This is what I've tried so far:

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:orientation="vertical"
                android:weightSum="2" >

                <Switch
                    android:id="@+id/remember_me_switch"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_weight="1"
                    android:hint="@string/remember" />

                <Button
                    android:id="@+id/share_button"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:layout_weight="1"
                    android:onClick="loginOnclick"
                    android:text="@string/login_button_text" />

            </LinearLayout>

通过此，按钮和开关采取父的所有空间而不是只需要一半。 我试着 Android的：layout_width = 0dp 的孩子，但它使它们消失

With this, the button and the switch take all the space of the parent instead of take only the half. I've tried with android:layout_width = 0dp in the children but it makes they disappear.

任何帮助，请？

推荐答案

一种可能的方式是有一个主水平的LinearLayout一个分割的宽度为2，它里面有垂直布局

One possible way is to have a master horizontal LinearLayout that splits the width to 2, and inside it have the vertical layout

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal" >
        <LinearLayout
            android:layout_height="wrap_content"
            android:layout_width="0dp"
            android:layout_weight="1"
            android:orientation="vertical" >

            <Switch
                android:id="@+id/remember_me_switch"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="@string/remember" />

            <Button
                android:id="@+id/share_button"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:onClick="loginOnclick"
                android:text="@string/login_button_text" />

        </LinearLayout>
        <!-- Right side spacer -->
        <View
           android:layout_width="0dp"
           android:layout_height="1dp"
           android:layout_weight="1" />

    </LinearLayout>
