通过设置双方的应用程序
主题属性安卓actionBarSize
和的 ActionBar.TabView
style属性安卓了minHeight
(或高度
)以80畅游。
By setting both the Application
theme attribute android:actionBarSize
and the ActionBar.TabView
style attribute android:minHeight
(or height
) to 80 dip.
有一个基本的例子:
<style name="ThemeHoloWithActionBar" parent="android:Theme.Holo.Light">
<item name="android:actionBarTabStyle">@style/ActionBarTabStyle</item>
<item name="android:actionBarSize">80dip</item>
</style>
<style name="ActionBarTabStyle" parent="@android:style/Widget.Holo.ActionBar.TabView">
<item name="android:minHeight">80dip</item>
</style>
在清单设置主题:
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/ThemeHoloWithActionBar" >
添加一些标签的动作条在活动:
Add some tabs to the ActionBar in an Activity:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ActionBar actionbar = getActionBar();
actionbar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
actionbar.setDisplayShowTitleEnabled(false);
actionbar.setDisplayShowHomeEnabled(false);
ActionBar.Tab tabA = actionbar.newTab().setText("Tab A");
ActionBar.Tab tabB = actionbar.newTab().setText("Tab B");
ActionBar.Tab tabC = actionbar.newTab().setText("Tab C");
tabA.setTabListener(new MyTabsListener());
tabB.setTabListener(new MyTabsListener());
tabC.setTabListener(new MyTabsListener());
actionbar.addTab(tabA);
actionbar.addTab(tabB);
actionbar.addTab(tabC);
}
这会产生在纵向模式下卡口与80浸高度:
This produces tabs with 80 dip height in portrait mode:
和80浸高度的标签在横向模式下:
and tabs with 80 dip height in landscape mode:
编辑:
有关本实施例中,SDK版本中的清单被设定为:
For this example, SDK versions in the Manifest were set to:
android:minSdkVersion="12"
android:targetSdkVersion="15"
据OP,这个例子与这些SDK设置。但是,如果 targetSkdVersion
,而不是被设置为16或17,本例不工作。 OP已提起错误报告:
According to OP, the example works with these SDK settings. However, if targetSkdVersion
is instead set to 16 or 17, the example doesn't work. OP has filed a bug report:
