android实现底部菜单栏

android程序，许多时候需要菜单栏显示在底部或顶部，但是没有很好的组建供程序员调用，过自定义了一个视图，用来实现底部菜单栏，效果如下图：

实现的主要代码：

@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); 
            } 
        }); 
    } 

 

配置文件实现：

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

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

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

        android:id="@+id/publish"> 
        <TextView android:layout_width="wrap_content"

             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">

             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"
