Android:在RelativeLayout中并排放置两个按钮

Vic*_*ent 8 xml android android-layout

RelativeLayout在底部有两个并排的按钮.我的目标是将这些按钮并排放置,但填充屏幕宽度.有人能告诉我怎么做吗?

我的布局文件是:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">

    <Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Left Button"
    android:id="@+id/button"
    android:layout_alignParentTop="false"
    android:layout_weight="1"
    android:layout_marginTop="77dp"
    android:layout_alignParentLeft="true"
    android:layout_alignParentBottom="true"
    android:layout_alignParentEnd="false"
    android:layout_alignParentStart="false" />

    <Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Right Button"
    android:id="@+id/button2"
    android:layout_weight="1"
    android:layout_toRightOf="@id/button"
    android:layout_alignParentBottom="true"
    android:layout_alignParentEnd="false"
    android:layout_alignParentStart="false" />
</RelativeLayout>

将按钮放在LinearLayout水平方向的按钮中.并为您的按钮分配重量.

这是您的代码,但已修改.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
            xmlns:tools="http://schemas.android.com/tools"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:paddingBottom="@dimen/activity_vertical_margin"
            android:paddingLeft="@dimen/activity_horizontal_margin"
            android:paddingRight="@dimen/activity_horizontal_margin"
            android:paddingTop="@dimen/activity_vertical_margin"
            tools:context=".MainActivity">\

<LinearLayout

    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:orientation="horizontal">

    <Button
        android:id="@+id/button"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="false"
        android:layout_weight="0.5"
        android:text="Left Button"
        />

    <Button
        android:id="@+id/button2"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="0.5"
        android:text="Right Button"
