<Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/replyButton" android:text="Reply"></Button>
<Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="RT" android:id="@+id/rtButton"></Button>
<Button android:id="@+id/dmButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="DM"></Button>
</LinearLayout>

Looks like you might want the padding attribute of the LinearLayout, e.g.
看起来你可能想要 LinearLayout 的 padding 属性,例如
android:padding="5dip"
To get the items to each take up the same amount of space, use layout_weight, e.g.
要让每个项目占用相同的空间,请使用 layout_weight,例如
<LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/toolbarLinearLayout" android:background="@color/solid_yellow">
<Button android:layout_width="fill_parent" android:layout_weight="1" android:layout_height="wrap_content" android:id="@+id/replyButton" android:text="Reply"></Button>
<Button android:layout_width="fill_parent" android:layout_weight="1" android:layout_height="wrap_content" android:text="RT" android:id="@+id/rtButton"></Button>
<Button android:id="@+id/dmButton" android:layout_width="fill_parent" android:layout_weight="1" android:layout_height="wrap_content" android:text="DM"></Button>
</LinearLayout>
As long as all the elements have the same weight they should take up the same space. layout_width="fill_parent" will ensure the whole bar is filled.
只要所有元素具有相同的权重,它们就应该占据相同的空间。layout_width="fill_parent" 将确保整个栏被填满。

Define your toolbar something like this:
像这样定义你的工具栏:
<LinearLayout ...>
<Button android:id="@+id/replyButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
...
/>
<View
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_weight="1"
/>
<Button ...
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<!-- etc. -->
</LinearLayout>
All the extra space will be allocated to the transparent views between the buttons.
所有额外的空间将分配给按钮之间的透明视图。

Add android:layout_margin="some value" for item in linearlayout.This worked for me.
为线性布局中的项目添加 android:layout_margin="some value"。这对我有用。
