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 

@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);         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：
