自定义tabhost实现

tabhost在网上随便找一下很多，但是真正全的东西还是不多，这里总结下我的tabhost的实现的全过程。

1、定义tabhost的xml文件

arent"    android:layout_height="fill_parent" >

特别注意要加几个id： tabhost中的android:id="@android :id/tabhost" FramFrameLayout中的android:id="@android :id/tabcontent" TabWidget中的android:id="@android :id/tabs"一定要添加，否则报错。还有个地方值得注意的，就是FramFrameLayout中的android:layout_weight="1.0"和TabWidget中的 android:layout_weight="0.0"用来控制tabhost组件显示在屏幕最下方。

其中style/tab_style

2、写一个继承TabActivity的类,要写在onstart方法里

public class TabHostActivity extends TabActivity {private TabHost tabHost;public static final String TAB_ITEM_1 = "tabItem1";public static final String TAB_ITEM_2 = "tabItem2";public static final String TAB_ITEM_3 = "tabItem3";public static final String TAB_ITEM_4 = "tabItem4";public static final String TAB_ITEM_5 = "tabItem5";private RadioGroup radiogroup;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);requestWindowFeature(Window.FEATURE_NO_TITLE);setContentView(R.layout.activity_tabhost);WelcomeActivity.myActivitiesList.add(this);radiogroup = (RadioGroup) findViewById(R.id.tabhost_radio);radiogroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {public void onCheckedChanged(RadioGroup group, int checkedId) {switch (checkedId) {case R.id.radio_button1:tabHost.setCurrentTabByTag(TAB_ITEM_1);break;case R.id.radio_button2:tabHost.setCurrentTabByTag(TAB_ITEM_2);break;case R.id.radio_button3:tabHost.setCurrentTabByTag(TAB_ITEM_3);break;case R.id.radio_button4:tabHost.setCurrentTabByTag(TAB_ITEM_4);break;case R.id.radio_button5:tabHost.setCurrentTabByTag(TAB_ITEM_5);break;default:break;}}});tabHost = getTabHost();}@Overrideprotected void onStart() {super.onStart();TabSpec tab1b = tabHost.newTabSpec(TAB_ITEM_1);TabSpec tab2b = tabHost.newTabSpec(TAB_ITEM_2);TabSpec tab3b = tabHost.newTabSpec(TAB_ITEM_3);TabSpec tab4b = tabHost.newTabSpec(TAB_ITEM_4);TabSpec tab5b = tabHost.newTabSpec(TAB_ITEM_5);tab1b.setIndicator(TAB_ITEM_1).setContent(new Intent(this, Test.class));tab2b.setIndicator(TAB_ITEM_2).setContent(new Intent(this, Test.class));tab3b.setIndicator(TAB_ITEM_3).setContent(new Intent(this, Test.class));tab4b.setIndicator(TAB_ITEM_4).setContent(new Intent(this, Test.class));tab5b.setIndicator(TAB_ITEM_5).setContent(new Intent(this, Test.class));tabHost.addTab(tab1b);tabHost.addTab(tab2b);tabHost.addTab(tab3b);tabHost.addTab(tab4b);tabHost.addTab(tab5b);}}

完成，一个自定义的tabhost完成
