如何在 ActionBar 中显示自定义视图? [英] How to display custom view in ActionBar?

问题描述

我想在操作栏中显示自定义搜索(为此我使用 ActionBarSherlock).

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

我明白了:

但我想让自定义布局(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.

我已经按照此处的建议实现了自定义布局.

I've implemented custom layout as suggested here.

有我的自定义布局 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>

在 MyActivity 中:

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);

如何让自定义布局占据 actionBar 的所有可用宽度?

How can I make custom layout to occupy all the available width of actionBar?

请帮忙.

推荐答案

对此有一个技巧.您所要做的就是使用 RelativeLayout 而不是 LinearLayout 作为主容器.为它设置 android:layout_gravity="fill_horizo​​ntal" 很重要.应该这样做.

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.
