采用TabHost和RadioButton实现页面导航效果

实现的效果不解释，主要是记录一下代码

先看一下xml布局：

<?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: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="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:background="@drawable/maintab_toolbar_bg"            android:visibility="gone" />        <RadioGroup            android:id="@id/main_radio"            android:layout_width="fill_parent"            android:layout_height="wrap_content"            android:layout_gravity="bottom"            android:background="@drawable/maintab_toolbar_bg"            android:gravity="center_vertical"            android:orientation="horizontal" >            <RadioButton                android:id="@id/radio_contact"                style="@style/main_tab_bottom"                android:drawableTop="@drawable/main_tab_contact_checked"                android:text="@string/radio_contact" />            <RadioButton                android:id="@id/radio_calllist"                style="@style/main_tab_bottom"                android:layout_marginTop="0dip"                android:layout_marginBottom="0dip"                android:drawableTop="@drawable/main_tab_calllist_normal"                android:text="@string/radio_calllist" />            <RadioButton                android:id="@id/radio_sms"                style="@style/main_tab_bottom"                android:layout_marginTop="0dip"                android:layout_marginBottom="0dip"                android:drawableTop="@drawable/main_tab_sms_normal"                android:text="@string/radio_sms" />            <RadioButton                android:id="@id/radio_setting"                style="@style/main_tab_bottom"                android:layout_marginTop="0dip"                 android:layout_marginBottom="0dip"                android:drawableTop="@drawable/nav_menu_me"                android:text="@string/radio_setting" />        </RadioGroup>    </LinearLayout></TabHost>

二、MainTabActivity

package com.gs.app.main;import android.app.TabActivity;import android.content.Intent;import android.os.Bundle;import android.view.Window;import android.widget.CompoundButton;import android.widget.CompoundButton.OnCheckedChangeListener;import android.widget.RadioButton;import android.widget.TabHost;import com.gs.Appblue.R;import com.gs.app.contact.ContactsListActivity;import com.gs.app.contact.RecentCallsListActivity;import com.gs.app.setting.Setting;import com.gs.app.sms.ActSMSList;public class MainTabActivity extends TabActivity implementsOnCheckedChangeListener {private TabHost mTabHost;private Intent mContactIntent;private Intent mCallLogIntent;private Intent mSmsIntent;private Intent mSetIntent;public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);requestWindowFeature(Window.FEATURE_NO_TITLE);setContentView(R.layout.main_tab);this.mContactIntent = new Intent(this, ContactsListActivity.class);this.mCallLogIntent = new Intent(this, RecentCallsListActivity.class);this.mSmsIntent = new Intent(this, ActSMSList.class);this.mSetIntent = new Intent(this, Setting.class);((RadioButton) findViewById(R.id.radio_contact)).setOnCheckedChangeListener(this);((RadioButton) findViewById(R.id.radio_calllist)).setOnCheckedChangeListener(this);((RadioButton) findViewById(R.id.radio_sms)).setOnCheckedChangeListener(this);((RadioButton) findViewById(R.id.radio_setting)).setOnCheckedChangeListener(this);setupIntent();}private void setupIntent() {this.mTabHost = getTabHost();TabHost localTabHost = this.mTabHost;localTabHost.addTab(buildTabSpec("A_TAB", R.string.radio_contact,R.drawable.main_tab_contact_normal, this.mContactIntent));localTabHost.addTab(buildTabSpec("B_TAB", R.string.radio_calllist,R.drawable.main_tab_calllist_normal, this.mCallLogIntent));localTabHost.addTab(buildTabSpec("C_TAB", R.string.radio_sms,R.drawable.main_tab_sms_normal, this.mSmsIntent));localTabHost.addTab(buildTabSpec("D_TAB", R.string.radio_setting,R.drawable.main_tab_setting_normal, this.mSetIntent));localTabHost.setCurrentTab(0);}@Overridepublic void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {if (isChecked) {switch (buttonView.getId()) {case R.id.radio_contact:this.mTabHost.setCurrentTabByTag("A_TAB");break;case R.id.radio_calllist:this.mTabHost.setCurrentTabByTag("B_TAB");break;case R.id.radio_sms:this.mTabHost.setCurrentTabByTag("C_TAB");break;case R.id.radio_setting:this.mTabHost.setCurrentTabByTag("D_TAB");break;}}}private TabHost.TabSpec buildTabSpec(String tag, int resLabel, int resIcon,final Intent content) {return this.mTabHost.newTabSpec(tag).setIndicator(getString(resLabel),getResources().getDrawable(resIcon)).setContent(content);}}
