我将main.xml
定义为:
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@+id/notifications"
android:icon="@drawable/ic_notifications"
android:title="@string/notifications" />
<item
android:id="@+id/reportsView"
android:icon="@drawable/ic_reports"
android:showAsAction="always"
android:title="@string/reportsView" />
<item
android:id="@+id/userProfile"
android:icon="@drawable/ic_profile"
android:title="@string/userProfile" />
</menu>
在活动中我有这个:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
但我仍然无法看到操作栏上的按钮。任何人都可以告诉我缺少什么
styles.xml
:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<!--
Base application theme, dependent on API level. This theme is replaced
by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
-->
<style name="AppBaseTheme" parent="android:Theme.Light">
<!--
Theme customizations available in newer API levels can go in
res/values-vXX/styles.xml, while customizations related to
backward-compatibility can go here.
-->
</style>
<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
<!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>
<style name="FullscreenTheme" parent="android:Theme.NoTitleBar">
<item name="android:windowContentOverlay">@null</item>
<item name="android:windowBackground">@null</item>
<item name="metaButtonBarStyle">@style/ButtonBar</item>
<item name="metaButtonBarButtonStyle">@style/ButtonBarButton</item>
</style>
<style name="ButtonBar">
<item name="android:paddingLeft">2dp</item>
<item name="android:paddingTop">5dp</item>
<item name="android:paddingRight">2dp</item>
<item name="android:paddingBottom">0dp</item>
<item name="android:background">@android:drawable/bottom_bar</item>
</style>
<style name="ButtonBarButton" />
</resources>

这些项目不会出现在您的ActionBar中,因为您没有明确告诉它们可见:
android:showAsAction="always"
<击>
如果您正在使用支持包中的活动类(例如ActionBarActivity
),则还需要使用这样的自定义命名空间:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:myapp="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/notifications"
android:icon="@drawable/ic_notifications"
myapp:showAsAction="always"
android:title="@string/notifications" />
<item
android:id="@+id/reportsView"
android:icon="@drawable/ic_reports"
myapp:showAsAction="always"
android:title="@string/reportsView" />
<item
android:id="@+id/userProfile"
android:icon="@drawable/ic_profile"
myapp:showAsAction="always"
android:title="@string/userProfile" />
</menu>
击> <击> 撞击>

这不是很有说服力,但也会覆盖它......
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
// TODO Auto-generated method stub
return true //return super.onPrepareOptionsMenu(menu);
}
或者清理你的项目..重新启动......所有这些
