android怎样实现下面的菜单栏

实现的主要代码：

Java代码：

@Override    

    public void onCreate(Bundle savedInstanceState) {    

        super.onCreate(savedInstanceState)    

        requestWindowFeature(Window.FEATURE_NO_TITLE)    

        setContentView(R.layout.main)    

   

        linearLayout = (LinearLayout) findViewById(R.id.home)    

        linearLayout.setOnClickListener(new OnClickListener() {    

            @Override    

            public void onClick(View v) {    

                linearLayout    

                        .setBackgroundResource(R.drawable.tab_two_highlight)    

                publish.setBackgroundResource(R.drawable.tab_one_normal)    

                change.setBackgroundResource(R.drawable.tab_one_normal)    

                more.setBackgroundResource(R.drawable.tab_one_normal)    

            }    

        })    

        linearLayout    

        .setBackgroundResource(R.drawable.tab_two_highlight)    

   

        publish = (LinearLayout) findViewById(R.id.publish)    

        publish.setOnClickListener(new OnClickListener() {    

            @Override    

            public void onClick(View v) {    

                publish.setBackgroundResource(R.drawable.tab_two_highlight)    

                linearLayout.setBackgroundResource(R.drawable.tab_one_normal)    

                change.setBackgroundResource(R.drawable.tab_one_normal)    

                more.setBackgroundResource(R.drawable.tab_one_normal)    

            }    

        })    

   

        change = (LinearLayout) findViewById(R.id.change)    

        change.setOnClickListener(new OnClickListener() {    

            @Override    

            public void onClick(View v) {    

                change.setBackgroundResource(R.drawable.tab_two_highlight)    

                linearLayout.setBackgroundResource(R.drawable.tab_one_normal)    

                publish.setBackgroundResource(R.drawable.tab_one_normal)    

                more.setBackgroundResource(R.drawable.tab_one_normal)    

            }    

        })    

   

        more = (LinearLayout) findViewById(R.id.more)    

        more.setOnClickListener(new OnClickListener() {    

            @Override    

            public void onClick(View v) {    

                more.setBackgroundResource(R.drawable.tab_two_highlight)    

                linearLayout.setBackgroundResource(R.drawable.tab_one_normal)    

                publish.setBackgroundResource(R.drawable.tab_one_normal)    

                change.setBackgroundResource(R.drawable.tab_one_normal)    

            }    

        })    

    }    

@Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState)         requestWindowFeature(Window.FEATURE_NO_TITLE)

配置文件实现：

Xml代码：

<?xml version="1.0" encoding="utf-8"?>    

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    

    android:orientation="horizontal" android:layout_width="fill_parent"    

    android:layout_height="wrap_content">    

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    

        android:orientation="vertical" android:layout_width="80px"    

        android:layout_height="wrap_content" android:id="@+id/home"    

        android:background="@drawable/tab_one_normal">    

        <TextView android:layout_width="wrap_content"    

            android:layout_height="wrap_content" android:text="@string/home"    

            android:gravity="center" android:paddingTop="29px"    

            android:background="@drawable/home" />    

    </LinearLayout>    

    <ImageView android:layout_width="wrap_content"    

            android:layout_height="wrap_content"  android:src="@drawable/line" />    

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    

        android:orientation="vertical" android:layout_width="80px"    

        android:layout_height="wrap_content" android:background="@drawable/tab_one_normal"    

        android:id="@+id/publish">    

        <TextView android:layout_width="wrap_content"    

            android:layout_height="wrap_content" android:text="@string/publish"    

            android:gravity="center" android:paddingTop="29px"    

             android:background="@drawable/publish" />    

    </LinearLayout>    

    <ImageView android:layout_width="wrap_content"    

            android:layout_height="wrap_content"  android:src="@drawable/line" />    

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    

        android:orientation="vertical" android:layout_width="80px" android:id="@+id/change"    

        android:layout_height="wrap_content" android:background="@drawable/tab_one_normal">    

        <TextView android:layout_width="wrap_content"    

            android:layout_height="wrap_content" android:text="@string/change"    

            android:gravity="center" android:paddingTop="29px"    

             android:background="@drawable/change" />    

    </LinearLayout>    

    <ImageView android:layout_width="wrap_content"    

            android:layout_height="wrap_content"  android:src="@drawable/line" />    

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    

        android:orientation="vertical" android:layout_width="80px" android:id="@+id/more"    

        android:layout_height="wrap_content" android:background="@drawable/tab_one_normal">    

        <TextView android:layout_width="wrap_content"    

            android:layout_height="wrap_content" android:text="@string/more"    

            android:gravity="center" android:paddingTop="29px"    

             android:background="@drawable/more" />    

    </LinearLayout>    

</LinearLayout>

代码详见:http://easymorse.googlecode.com/svn/trunk/android.bottom/

在res下新建menu文件夹,然后新建菜单文件

定义一个xml文件（在menu资源里面），

<menu xmlns:android="http://schemas.android.com/apk/res/android">

<item

android:id="@+id/menu_settings"

android:showAsAction="never"

android:title="设置" />

<item

android:id="@+id/menu_exit"

android:showAsAction="never"

android:title="退出" />

</menu>

（item有多少个，显示就多少个）

在代码里面的onCreateOptionsMenu方法里面把这个xml布局填充进去，代码如下：

MenuInflater inflater = getMenuInflater()

inflater.inflate(R.menu.menu_settings, menu)
