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：
01@Override
02 public void onCreate(Bundle savedInstanceState) {
03 super.onCreate(savedInstanceState);
04 requestWindowFeature(Window.FEATURE_NO_TITLE);
05 setContentView(R.layout.main); linearLayout = (LinearLayout) findViewById(R.id.home);
06 linearLayout.setOnClickListener(new OnClickListener() {
07 @Override
08 public void onClick(View v) {
09 linearLayout
10 .setBackgroundResource(R.drawable.tab_two_highlight);
11 publish.setBackgroundResource(R.drawable.tab_one_normal);
12 change.setBackgroundResource(R.drawable.tab_one_normal);
13 more.setBackgroundResource(R.drawable.tab_one_normal);
14 }
15 });
16 linearLayout
17 .setBackgroundResource(R.drawable.tab_two_highlight); publish = (LinearLayout) findViewById(R.id.publish);
18 publish.setOnClickListener(new OnClickListener() {
19 @Override
20 public void onClick(View v) {
21 publish.setBackgroundResource(R.drawable.tab_two_highlight);
22 linearLayout.setBackgroundResource(R.drawable.tab_one_normal);
23 change.setBackgroundResource(R.drawable.tab_one_normal);
24 more.setBackgroundResource(R.drawable.tab_one_normal);
25 }
26 }); change = (LinearLayout) findViewById(R.id.change);
27 change.setOnClickListener(new OnClickListener() {
28 @Override
29 public void onClick(View v) {
30 change.setBackgroundResource(R.drawable.tab_two_highlight);
31 linearLayout.setBackgroundResource(R.drawable.tab_one_normal);
32 publish.setBackgroundResource(R.drawable.tab_one_normal);
33 more.setBackgroundResource(R.drawable.tab_one_normal);
34 }
35 }); more = (LinearLayout) findViewById(R.id.more);
36 more.setOnClickListener(new OnClickListener() {
37 @Override
38 public void onClick(View v) {
39 more.setBackgroundResource(R.drawable.tab_two_highlight);
40 linearLayout.setBackgroundResource(R.drawable.tab_one_normal);
41 publish.setBackgroundResource(R.drawable.tab_one_normal);
42 change.setBackgroundResource(R.drawable.tab_one_normal);
43 }
44 });
45 }
