推荐答案

使用这种方式，您可以制作 header-footer xml 并将其用于您的任何 activity此外，您只需要在 HeaderFooter.java 中的页眉页脚中为控件编写代码，即可访问您的项目.

Using this way you can make your header-footer xml and use it to any of your activity also you just need to write code for the controls in header-footer once in HeaderFooter.java and can access it your project.

构建你的 HederFooter.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="fill_parent"
    android:layout_height="fill_parent" android:weightSum="10"
    android:id="@+id/commonlayout" android:background="#FFFFFF">
    <LinearLayout android:id="@+id/llheader"
        android:layout_width="fill_parent" android:layout_height="0dp"
        android:background="@drawable/bar" android:layout_weight="1">



        <RelativeLayout android:id="@+id/relativeLayout1"
            android:layout_width="fill_parent" android:layout_height="fill_parent"
            android:layout_gravity="center">
            <Button
                android:id="@+id/Button_HeaderFooterSubscribe"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentRight="true"
                android:layout_marginRight="2dp"
                android:layout_centerVertical="true"
                android:background="@drawable/subscribe"
                />
                <Button
                android:id="@+id/Button_logout"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentRight="true"
                android:layout_marginRight="2dp"
                android:layout_centerVertical="true"
                android:background="@drawable/logout"
                />
                <Button
                android:id="@+id/Button_playlist"
                android:layout_marginLeft="2dp"
                android:layout_width="wrap_content"
                android:layout_centerVertical="true"
                android:layout_height="wrap_content"
                android:layout_alignParentLeft="true"
                android:background="@drawable/tempadd"
                />



</RelativeLayout>

    </LinearLayout>
    <LinearLayout android:id="@+id/lldata"
        android:layout_weight="8" android:layout_width="fill_parent"
        android:layout_height="0dp" android:background="#FFFFFF">


    </LinearLayout>

    <LinearLayout android:id="@+id/llfooter"
        android:layout_weight="1" android:layout_width="fill_parent"
        android:orientation="horizontal" android:layout_height="0dp"
        android:visibility="visible" android:background="@drawable/fbg"
        android:weightSum="5.0" android:gravity="center"
        android:layout_margin="0dp">

        <Button android:id="@+id/home" android:layout_height="wrap_content"
            android:layout_width="wrap_content" android:layout_weight="1"
            android:background="@drawable/home" android:textColor="#FFFFFF"
            android:padding="10px"></Button>

        <Button android:id="@+id/issue" android:layout_height="wrap_content"
            android:layout_width="wrap_content" android:layout_weight="1"
            android:background="@drawable/issue" android:textColor="#FFFFFF"
            android:padding="10px"></Button>

        <Button android:id="@+id/browse" android:layout_height="wrap_content"
            android:layout_width="wrap_content" android:layout_weight="1"
            android:background="@drawable/browse" android:textColor="#FFFFFF"
            android:padding="10px"></Button>

        <Button android:id="@+id/search" android:layout_height="wrap_content"
            android:layout_width="wrap_content" android:layout_weight="1"
            android:background="@drawable/search" android:textColor="#FFFFFF"
            android:padding="10px"></Button>

        <Button android:layout_height="wrap_content" android:id="@+id/favorite"
            android:background="@drawable/favorite" android:layout_width="wrap_content"
            android:layout_weight="1"
            android:textColor="#FFFFFF" android:padding="10px"></Button>
    </LinearLayout>

</LinearLayout>

然后创建一个HeaderFooter.java Activity

public class HeaderFooter extends Activity {
        public void onCreate(Bundle savedInstanceState) {
             super.onCreate(savedInstanceState);
             setContentView(R.layout.headerfooter);
        }
 }

现在将上述活动扩展到您的所有其他活动，并在 headerfooter.xml 的中间布局中扩展您的特定视图

public class Home extends HeaderFooter 
{
        @Override
        public void onCreate(Bundle savedInstanceState)
        {
            super.onCreate(savedInstanceState);
            ViewGroup vg = (ViewGroup) findViewById(R.id.lldata);
            ViewGroup.inflate(Home.this, R.layout.home, vg);
        }
}
