我想显示自定义的动作条搜索（我使用ActionBarSherlock为）。

I want to display custom search in actionbar (I'm using ActionBarSherlock for that).

我得到的：

不过，我想进行自定义布局（的EditText字段）占据整个可用宽度。

But I want make custom layout (edittext field) to occupy the entire available width.

我实现自定义布局的建议here.

I've implemented custom layout as suggested here.

还有就是我的自定义布局 search.xml ：

There is my custom layout search.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    style="?attr/actionButtonStyle"
    android:layout_width="fill_parent"
    android:layout_height="match_parent"
    android:layout_gravity="fill_horizontal"
    android:focusable="true" >

    <FrameLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical|fill_horizontal" >

        <EditText
            android:id="@+id/search_query"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="left|center"
            android:background="@drawable/bg_search_edit_text"
            android:imeOptions="actionSearch"
            android:inputType="text" />

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="right|center_vertical"
            android:src="@drawable/ic_search_arrow" />

    </FrameLayout>

</LinearLayout>

而在 MyActivity ：

ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setIcon(R.drawable.ic_action_search);

LayoutInflater inflator = (LayoutInflater) this .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = inflator.inflate(R.layout.search, null);

actionBar.setCustomView(v);

我怎样才能让自定义布局中占据动作条？

帮助，请。

推荐答案

有一个窍门这一点。你所要做的就是用 RelativeLayout的而不是的LinearLayout 作为主容器。它有很重要安卓layout_gravity =fill_horizo​​ntal设置它。这应该做到这一点。

There is a trick for this. All you have to do is to use RelativeLayout instead of LinearLayout as the main container. It's important to have android:layout_gravity="fill_horizontal" set for it. That should do it.
