原创：http://www.haolizi.net/example/view_447.html 【实例简介】【实例截图】 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
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： 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
实现代码如下 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 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： 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62
drawable/home_btn_bg.xml：切换时的效果： 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 string/dimens.xml 尺寸文件： 2.0dip 5.0dip 10.0dip string/drawables.xml 设置为透明: #00000000 string/styles.xml 样式文件: @dimen/bottom_tab_font_size #ffffffff marquee center_horizontal @drawable/home_btn_bg @dimen/bottom_tab_padding_up fill_parent wrap_content @null true @dimen/bottom_tab_padding_drawable 1.0 代码实现： 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 import android.app.TabActivity; import android.content.Intent; import android.os.Bundle; import android.view.Window; import android.widget.RadioGroup; import android.widget.TabHost; import android.widget.RadioGroup.OnCheckedChangeListener; public class MainTabActivity extends TabActivity implements OnCheckedChangeListener{ private RadioGroup mainTab; private TabHost tabhost; private Intent iHome; private Intent iNews; private Intent iInfo; private Intent iSearch; private Intent iMore; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.main); mainTab=(RadioGroup)findViewById(R.id.main_tab); mainTab.setOnCheckedChangeListener(this); tabhost = getTabHost(); iHome = new Intent(this, HomeActivity.class); tabhost.addTab(tabhost.newTabSpec("iHome") .setIndicator(getResources().getString(R.string.main_home), getResources().getDrawable(R.drawable.icon_1_n)) .setContent(iHome)); iNews = new Intent(this, NewsActivity.class); tabhost.addTab(tabhost.newTabSpec("iNews") .setIndicator(getResources().getString(R.string.main_news), getResources().getDrawable(R.drawable.icon_2_n)) .setContent(iNews)); iInfo = new Intent(this, MyInfoActivity.class); tabhost.addTab(tabhost.newTabSpec("iInfo") .setIndicator(getResources().getString(R.string.main_my_info), getResources().getDrawable(R.drawable.icon_3_n)) .setContent(iInfo)); iSearch = new Intent(this,SearchActivity.class); tabhost.addTab(tabhost.newTabSpec("iSearch") .setIndicator(getResources().getString(R.string.menu_search), getResources().getDrawable(R.drawable.icon_4_n)) .setContent(iSearch)); iMore = new Intent(this, MoreActivity.class); tabhost.addTab(tabhost.newTabSpec("iMore") .setIndicator(getResources().getString(R.string.more), getResources().getDrawable(R.drawable.icon_5_n)) .setContent(iMore)); } @Override public void onCheckedChanged(RadioGroup group, int checkedId) { switch(checkedId){ case R.id.radio_button0: this.tabhost.setCurrentTabByTag("iHome"); break; case R.id.radio_button1: this.tabhost.setCurrentTabByTag("iNews"); break; case R.id.radio_button2: this.tabhost.setCurrentTabByTag("iInfo"); break; case R.id.radio_button3: this.tabhost.setCurrentTabByTag("iSearch"); break; case R.id.radio_button4: this.tabhost.setCurrentTabByTag("iMore"); break; } } }
