@H_301_1@

<?xml version="1.0" enCoding="utf-8"?><manifest xmlns:androID="http://schemas.androID.com/apk/res/androID"package="com.belsoft.myapplication"><application    androID:allowBackup="true"    androID:icon="@mipmap/ic_launcher"    androID:label="@string/app_name"    androID:supportsRtl="true"    androID:uiOptions="splitactionbarWhenNarrow"    androID:theme="@style/Apptheme">    <activity        androID:name=".MainActivity"        androID:label="@string/app_name"        androID:theme="@style/Apptheme.NoActionbar">        <intent-filter>            <action androID:name="androID.intent.action.MAIN" />            <category androID:name="androID.intent.category.LAUNCHER" />        </intent-filter>    </activity></application></manifest>

我哪里错了？@H_301_1@

解决方法:@H_301_1@

要实现splitactionbar：@H_301_1@

只需将androID：uiOptions =“splitactionbarWhenNarrow”添加到AndroIDManifest.xml中的活动标签,就像这样……@H_301_1@

`<activity    androID:name=".MainActivity"    androID:uiOptions="splitactionbarWhenNarrow">`<br>

NOTE: It is available ONLY for handset devices with a screen wIDth
of 400dp.@H_301_1@

Creating custom bottom toolbar

I’ve already created a simple app which should demonstrate you how to
begin@H_301_1@

@H_301_1@ @H_301_1@Creating a custom VIEwGroup

Here’s my activity_main.xml layout file:@H_301_1@

06001@H_301_1@

As you can see my parent VIEwGroup is relativeLayout, which simply
allows me to create a vIEw at the bottom of screen. @H_301_1@

Notice that I set layout padding to zero (I think: setting layout
margin to zero here is not necessary, the same effect). If you’d
change it, the toolbar won’t use full wIDth and it won’t stick with
bottom of the screen.@H_301_1@

Then I added a linear Layout with hardcoded height which is:@H_301_1@

06002@H_301_1@

I wanted it, that my bottom toolbar would take full available wIDth so
I set it as match_parent.@H_301_1@

Next, I added some Imagebutton vIEws with images from AndroID
library.@H_301_1@

There you have two possibilitIEs:@H_301_1@

if you really want to have a toolbar like in above example just remove in every Imagebutton vIEw this line:@H_301_1@

06003@H_301_1@

After removing weights and some buttons you would get a vIEw pretty
similar to expected:@H_301_1@

@H_301_1@@H_301_1@if you want to take the full wIDth and make every button with the same size use in your project weight as in this mine example.

Now let’s go to my AndroIDManifest.xml@H_301_1@

06004@H_301_1@

In that file I’d added as you can see only one additional line:@H_301_1@

06005@H_301_1@

to make sure that device keyboard won’t hIDe my custom bottom toolbar.@H_301_1@
