Android实现底部菜单Tab
以前在我的博客里面写过模仿网易新闻客户端顶部菜单Tab的文章
http://blog.csdn.NET/shineflowers/article/details/41349703
现在使用静态的Fragment来实现底部Tab的功能:

xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
android:id="@+id/fragment"
android:name="com.example.fragment.ContentFragment"
android:layout_width="fill_parent"
android:layout_height="300dp"
/>
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
android:id="@+id/btn_news"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="新闻"
android:layout_weight="1"
/>
android:id="@+id/btn_entertainment"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="娱乐"
android:layout_weight="1"
/>
android:id="@+id/btn_political"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="政治"
android:layout_weight="1"
/>
android:id="@+id/btn_sports"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="体育"
android:layout_weight="1"
/>
要实现的功能就是点击下面四个按钮，内容进行切换：

BundlesavedInstanceState){
rootView=inflater.inflate(R.layout.activity_news,null);
tv_content=(TextView)rootView.findViewById(R.id.tv_content);
returnrootView;
}
@Override

super.onCreate(savedInstanceState);
}

tv_content.setText(msg);
}
}

}
@Override
publicvoidonClick(Viewv){
switch(v.getId()){

}
