2个按钮之间的LinearLayout间距

Question

this is my linearLayout:

<LinearLayout
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    xmlns:android="http://schemas.android.com/apk/res/android">

    <Button
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="ANNULLA"
        android:id="@+id/button4"
        android:layout_gravity="bottom"
        android:textColor="#FFF"
        android:background="#87a914"
        android:textStyle="bold"
        android:textSize="20dp"
        android:layout_marginBottom="2dp"
        android:layout_marginLeft="3dp" />

    <Button
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="SALVA"
        android:id="@+id/button5"
        android:layout_gravity="bottom"
        android:textColor="#FFF"
        android:background="#87a914"
        android:textStyle="bold"
        android:textSize="20dp"
        android:layout_marginBottom="2dp"
        android:layout_marginRight="3dp" />
</LinearLayout>

and this the result:

I would like to have a space between the button "SALVA" and the button "ANNULLA"

Answer 1

只需在第二个按钮中添加此属性

android:layout_marginLeft="xdp" 

Answer 2

我最喜欢的方法是在按钮之间添加不可见视图，如下所示：

<View android:layout_width="5dp" android:layout_height="wrap_content" android:visibility="invisible" />

Answer 3

One way is to add an empty View in between them with a suitable weight

<View
    android:layout_width="0dp"
    android:layout_height-"wrap_content"
    android:layout_weight=".2"/>  // change this to what works for you

your width for the Buttons should be "0dp" when using layout_weight
