通过TabWidget实现

通过TabWidget实现 android底部菜单

 

实现方式二：隐藏TabWidget，通过RadioGroup和RadioButton实现底部菜单栏

实现方式二：隐藏TabWidget，通过RadioGroup和RadioButton实现底部菜单栏
【核心代码】

 

实现方式一：通过TabWidget实现

这种方式主要是在布局中将TabWidget标签嵌套在RelativeLayout中，并且在TabWidget标签中中设置 android:layout_alignParentBottom="true"

另外，下划线和选项卡之间的线去除的方法时在TabWidget标签中设置属性android:tabStripEnabled="false"

    <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">
        <!-- tabStripEnabled属性去掉底部下划线与选项卡间的下划线 -->
        <!-- layout_alignParentBottom属性即可将其放在底部菜单栏，注意，必须在RelativeLayout里 -->
        <TabWidget
            android:id="@android:id/tabs"
            android:tabStripEnabled="false"
            android:background="#6E6E6E"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        tabhost = getTabHost();
         
        intent1 = new Intent(Demo1Activity.this, One.class);
        tabhost.addTab(tabhost.newTabSpec("one")
                .setIndicator("电话",getResources().getDrawable(android.R.drawable.ic_menu_call))
                .setContent(intent1));
         
        intent2 = new Intent(Demo1Activity.this, Two.class);
        tabhost.addTab(tabhost.newTabSpec("two")
                .setIndicator("相机",getResources().getDrawable(android.R.drawable.ic_menu_camera))

        intent3 = new Intent(Demo1Activity.this, Three.class);
        tabhost.addTab(tabhost.newTabSpec("three")
                .setIndicator("分享",getResources().getDrawable(android.R.drawable.ic_menu_share))
                .setContent(intent3));
         
        intent4 = new Intent(Demo1Activity.this, Four.class);
        tabhost.addTab(tabhost.newTabSpec("four")
                .setIndicator("更多",getResources().getDrawable(android.R.drawable.ic_menu_more))
                .setContent(intent4));
    }
}

 

 

 

 

实现方式二：隐藏TabWidget，通过RadioGroup和RadioButton实现底部菜单栏

这种方式更漂亮，也更灵活，网上基本用的是这种方式，通过setCurrentTabByTag来切换不同的选项卡
