上一篇文章介绍了ActionBar的使用,这里介绍ActionBar的另一种使用方法,达到的效果和以前的GroupActivity或TabHost是一样的,可作为导航来使用。
实现效果图:
源代码:
布局文件:activity_main:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/main" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity" android:background="@android:color/white"> </RelativeLayout>
<LinearLayout 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:orientation="vertical" tools:context=".MainActivity" > <TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:text="欢迎收看体育新闻..." android:textSize="20sp" android:textColor="@android:color/holo_blue_dark"/> <RatingBar android:id="@+id/ratingBar1" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout>
<LinearLayout 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" tools:context=".MainActivity" > <TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:text="欢迎收看娱乐新闻..." android:textColor="@android:color/holo_green_dark" android:textSize="20sp" /> </LinearLayout>
f3.xml(军事新闻):
<LinearLayout 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" tools:context=".MainActivity" > <TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:text="欢迎收看军事新闻..." android:textColor="@android:color/holo_orange_dark" android:textSize="20sp" /> </LinearLayout>
MainActivity:
