布局文件
activity_main.xml
<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/pager" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.example.actiontabbar.MainActivity" />
fragment_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="com.example.actiontabbar.MainActivity$PlaceholderFragment" > <TextView android:id="@+id/section_label" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </RelativeLayout>
菜单文件 appCompatV7
<menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" tools:context="com.example.actiontabbar.MainActivity" > <item android:id="@+id/action_search" android:orderInCategory="100" android:title="@string/action_search" app:actionViewClass="android.support.v7.widget.SearchView" app:showAsAction="ifRoom" /> <item android:id="@+id/action_camera" android:orderInCategory="100" android:icon="@drawable/ofm_camera_icon" android:title="@string/action_camera" app:showAsAction="never"/> <item android:id="@+id/action_plus" android:orderInCategory="100" android:icon="@drawable/ofm_add_icon" android:title="@string/action_plus" app:showAsAction="never"/> <item android:id="@+id/action_mail" android:orderInCategory="100" android:icon="@drawable/ofm_feedback_icon" android:title="@string/action_mail" app:showAsAction="never"/> <item android:id="@+id/action_settings" android:orderInCategory="100" android:icon="@drawable/ofm_setting_icon" android:title="@string/action_settings" app:showAsAction="never"/> </menu>
自定义标题
custom_actionbar.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <TextView android:id="@+id/m_actionbar_title" android:layout_width="match_parent" android:layout_height="match_parent" android:textSize="16sp" android:textColor="@android:color/white" android:gravity="center_vertical" android:drawableLeft="@drawable/abc_ic_menu_moreoverflow_normal_holo_dark" android:paddingLeft="1dip" android:drawablePadding="1dip" android:text="TextView" /> </LinearLayout>
