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：

Java代码

1. @Override   
2.     public void onCreate(Bundle savedInstanceState) {   
3.         super.onCreate(savedInstanceState);   
4.         requestWindowFeature(Window.FEATURE_NO_TITLE);   
5.         setContentView(R.layout.main);   
6.   
7.         linearLayout = (LinearLayout) findViewById(R.id.home);   
8.         linearLayout.setOnClickListener(new OnClickListener() {   
9.             @Override   
10.             public void onClick(View v) {   
11.                 linearLayout   
12.                         .setBackgroundResource(R.drawable.tab_two_highlight);   
13.                 publish.setBackgroundResource(R.drawable.tab_one_normal);   
14.                 change.setBackgroundResource(R.drawable.tab_one_normal);   
15.                 more.setBackgroundResource(R.drawable.tab_one_normal);   
16.             }   
17.         });   
18.         linearLayout   
19.         .setBackgroundResource(R.drawable.tab_two_highlight);   
20.   
21.         publish = (LinearLayout) findViewById(R.id.publish);   
22.         publish.setOnClickListener(new OnClickListener() {   
23.             @Override   
24.             public void onClick(View v) {   
25.                 publish.setBackgroundResource(R.drawable.tab_two_highlight);   
26.                 linearLayout.setBackgroundResource(R.drawable.tab_one_normal);   
27.                 change.setBackgroundResource(R.drawable.tab_one_normal);   
28.                 more.setBackgroundResource(R.drawable.tab_one_normal);   
29.             }   
30.         });   
31.   
32.         change = (LinearLayout) findViewById(R.id.change);   
33.         change.setOnClickListener(new OnClickListener() {   
34.             @Override   
35.             public void onClick(View v) {   
36.                 change.setBackgroundResource(R.drawable.tab_two_highlight);   
37.                 linearLayout.setBackgroundResource(R.drawable.tab_one_normal);   
38.                 publish.setBackgroundResource(R.drawable.tab_one_normal);   
39.                 more.setBackgroundResource(R.drawable.tab_one_normal);   
40.             }   
41.         });   
42.   
43.         more = (LinearLayout) findViewById(R.id.more);   
44.         more.setOnClickListener(new OnClickListener() {   
45.             @Override   
46.             public void onClick(View v) {   
47.                 more.setBackgroundResource(R.drawable.tab_two_highlight);   
48.                 linearLayout.setBackgroundResource(R.drawable.tab_one_normal);   
49.                 publish.setBackgroundResource(R.drawable.tab_one_normal);   
50.                 change.setBackgroundResource(R.drawable.tab_one_normal);   
51.             }   
52.         });   
53.     }   

@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：
