是否可以在 LinearLayout 的宽度上均匀分布按钮 [英] Is it possible to evenly distribute buttons across the width of a LinearLayout
问题描述
我有一个包含 3 个按钮的 LinearLayout
(水平方向).我希望这 3 个按钮具有固定的宽度并均匀分布在 LinearLayout
的宽度上.
I have a LinearLayout
(oriented horizontally) that contains 3 buttons. I want the 3 buttons to have a fixed width and be evenly distributed across the width of the LinearLayout
.
我可以通过将 LinearLayout
的重力设置为居中然后调整按钮的内边距来管理这一点,但这适用于固定宽度,不适用于不同的设备或方向.
I can manage this by setting the gravity of the LinearLayout
to center and then adjusting the padding of the buttons, but this works for a fixed width and won't work for different devices or orientations.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="horizontal">
<Button
android:id="@+id/btnOne"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:width="120dp" />
<Button
android:id="@+id/btnTwo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:width="120dp" />
<Button
android:id="@+id/btnThree"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:width="120dp" />
</LinearLayout>
推荐答案
Expanding on fedj's answer, if you set layout_width
to 0dp
and set the layout_weight
for each of the buttons to 1, the available width will be shared equally between the buttons.
