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：
