通过TabWidget实现

 

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"

 

xml：

 

xml version = "1.0" encoding = "utf-8" ?>
< TabHost xmlns:android = "http://schemas.android.com/apk/res/android"
    android:id = "@android:id/tabhost"
    android:layout_width = "fill_parent"
    android:layout_height = "fill_parent"
    android:orientation = "vertical" >
     < FrameLayout
            android:id = "@android:id/tabcontent"
            android:layout_width = "fill_parent"
            android:layout_height = "fill_parent"
            android:padding = "5dp"
            > FrameLayout >

    < RelativeLayout
        android:layout_width = "fill_parent"
        android:layout_height = "fill_parent" >


        < 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"
            > TabWidget >

    RelativeLayout >

TabHost >

 

实现代码如下

 

package com.loulijun.demo1;

import android.app.TabActivity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.TabHost;

public class Demo1Activity extends TabActivity {
    /** Called when the activity is first created. */
    private TabHost tabhost;
    private Intent intent1, intent2, intent3, intent4;
    @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))
                .setContent(intent2));

        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

main.xml：

 

xml version = "1.0" encoding = "utf-8" ?>
< TabHost xmlns:android = "http://schemas.android.com/apk/res/android"
    android:id = "@android:id/tabhost"
    android:layout_width = "fill_parent"
    android:layout_height = "fill_parent"
    >
    < LinearLayout
        android:orientation = "vertical"
        android:layout_width = "fill_parent"
        android:layout_height = "fill_parent" >
        < FrameLayout
            android:id = "@android:id/tabcontent"
            android:layout_width = "fill_parent"
            android:layout_height = "0.0dip"
            android:layout_weight = "1.0" />
        < TabWidget
            android:id = "@android:id/tabs"
            android:layout_width = "fill_parent"
            android:layout_height = "wrap_content"
            android:layout_weight = "0.0"
            android:visibility = "gone" />
        < RadioGroup
            android:id = "@ id/main_tab"
            android:background = "@drawable/maintab_toolbar_bg"
            android:orientation = "horizontal"
            android:layout_width = "fill_parent"
            android:layout_height = "wrap_content"
            android:gravity = "center_vertical"
            android:layout_gravity = "bottom" >
            < RadioButton
                android:layout_marginTop = "2.0dip"
                android:text = "@string/main_home"
                android:drawableTop = "@drawable/icon_1_n"
                android:id = "@ id/radio_button0"
                style = "@style/main_tab_bottom" />
            < RadioButton
                android:layout_marginTop = "2.0dip"
                android:text = "@string/main_news"
                android:drawableTop = "@drawable/icon_2_n"
                android:id = "@ id/radio_button1"
                style = "@style/main_tab_bottom" />
            < RadioButton
                android:layout_marginTop = "2.0dip"
                android:text = "@string/main_my_info"
                android:drawableTop = "@drawable/icon_3_n"
                android:id = "@ id/radio_button2"
                style = "@style/main_tab_bottom" />
            < RadioButton
                android:layout_marginTop = "2.0dip"
                android:text = "@string/menu_search"
                android:drawableTop = "@drawable/icon_4_n"
                android:id = "@ id/radio_button3"
                style = "@style/main_tab_bottom" />
            < RadioButton
                android:layout_marginTop = "2.0dip"
                android:text = "@string/more"
                android:drawableTop = "@drawable/icon_5_n"
                android:id = "@ id/radio_button4"
                style = "@style/main_tab_bottom" />
        RadioGroup >
    LinearLayout >
TabHost >

 

 

 

drawable/home_btn_bg.xml：切换时的效果：

 

xml version = "1.0" encoding = "UTF-8" ?>
< selector
  xmlns:android = "http://schemas.android.com/apk/res/android" >
    < item android:state_focused = "true" android:state_enabled = "true" android:state_pressed = "false" android:drawable = "@drawable/home_btn_bg_s" />
    < item android:state_enabled = "true" android:state_pressed = "true" android:drawable = "@drawable/home_btn_bg_s" />
    < item android:state_enabled = "true" android:state_checked = "true" android:drawable = "@drawable/home_btn_bg_d" />
    < item android:drawable = "@drawable/transparent" />
selector >

string/dimens.xml 尺寸文件：

xml version = "1.0" encoding = "utf-8" ?>
< resources >
    < dimen name = "bottom_tab_padding_drawable" >2.0dip dimen >
    < dimen name = "bottom_tab_padding_up" >5.0dip dimen >
    < dimen name = "bottom_tab_font_size" >10.0dip dimen >
resources >

string/drawables.xml 设置为透明:

xml version = "1.0" encoding = "utf-8" ?>
< resources >
< item type = "drawable" name = "transparent" >#00000000 item >
resources >

string/styles.xml 样式文件:

xml version = "1.0" encoding = "utf-8" ?>
< resources >
< style name = "main_tab_bottom" >
    < item name = "android:textSize" >@dimen/bottom_tab_font_size item >
    < item name = "android:textColor" >#ffffffff item >
    < item name = "android:ellipsize" >marquee item >
    < item name = "android:gravity" >center_horizontal item >
    < item name = "android:background" >@drawable/home_btn_bg item >
    < item name = "android:paddingTop" >@dimen/bottom_tab_padding_up item >
    < item name = "android:layout_width" >fill_parent item >
    < item name = "android:layout_height" >wrap_content item >
    < item name = "android:button" >@null item >
    < item name = "android:singleLine" >true item >
    < item name = "android:drawablePadding" >@dimen/bottom_tab_padding_drawable item >
    < item name = "android:layout_weight" >1.0 item >
