Android TabActivity 全套代码（结合Layout XML文件实现）

今天查了一下TabActivity的使用方法。网络上的文章不是很全面，且总结不够细致。所以特地将整幅代码整理出来，已方便大家查阅。初次写发布Android的源代码，不足指出请大家不吝赐教~ 闲话少说，下面进入正题。

 

我的开发环境是 Eclipse + Android SDK1.6。

 

Manifest.xml:

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.keven" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".MainFrame" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <uses-sdk android:minSdkVersion="4" /> </manifest>

 

MainFrame.java:

package com.keven; import android.app.AlertDialog; import android.app.TabActivity; import android.os.Bundle; import android.view.LayoutInflater; import android.view.Menu; import android.view.MenuInflater; import android.widget.TabHost; import android.widget.TabHost.OnTabChangeListener; import android.widget.TabHost.TabSpec; public class MainFrame extends TabActivity implements OnTabChangeListener { private TabHost tabHost; private TabSpec tab1, tab2, tab3; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); tabHost = this.getTabHost(); LayoutInflater.from(this).inflate(R.layout.main, tabHost.getTabContentView(), true); tab1 = tabHost.newTabSpec("Id1").setIndicator("Tab1", this.getResources().getDrawable(R.drawable.icon)).setContent( R.id.tab1); tabHost.addTab(tab1); tab2 = tabHost.newTabSpec("Id2").setIndicator("Tab2", this.getResources().getDrawable(R.drawable.icon)).setContent( R.id.tab2); tabHost.addTab(tab2); tab3 = tabHost.newTabSpec("Id3").setIndicator("Tab3", this.getResources().getDrawable(R.drawable.icon)).setContent( R.id.tab3); tabHost.addTab(tab3); tabHost.setOnTabChangedListener(this); } @Override public void onTabChanged(String tabId) { new AlertDialog.Builder(this).setTitle("Hint").setMessage(tabId) .setPositiveButton("OK", null).show(); } private int[] tabMenus = { R.menu.menu1, R.menu.menu2, R.menu.menu3 }; public boolean onPrepareOptionsMenu(Menu menu) { menu.clear(); MenuInflater inflater = getMenuInflater(); switch (tabHost.getCurrentTab()) { case 0: inflater.inflate(tabMenus[0], menu); break; case 1: inflater.inflate(tabMenus[1], menu); break; case 2: inflater.inflate(tabMenus[2], menu); break; default: break; } return super.onCreateOptionsMenu(menu); } }

 

LayOut文件，main.xml:

<?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:id="@+id/tab1" android:layout_width="fill_parent" android:layout_height="fill_parent" androidrientation="vertical"> </LinearLayout> <LinearLayout android:id="@+id/tab2" android:layout_width="fill_parent" android:layout_height="fill_parent" androidrientation="vertical"> </LinearLayout> <LinearLayout android:id="@+id/tab3" android:layout_width="fill_parent" android:layout_height="fill_parent" androidrientation="vertical"> </LinearLayout> </FrameLayout>

 

Menu文件，menu1.xml:

<?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/item01" android:title="Tab1 M1"></item> <item android:id="@+id/item02" android:title="Tab1 M2"></item> <item android:id="@+id/item03" android:title="Tab1 M3"></item> </menu>

Menu文件，menu2.xml:

<?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/item04" android:title="Tab2 M1"></item> <item android:id="@+id/item05" android:title="Tab2 M2"></item> <item android:id="@+id/item06" android:title="Tab2 M3"></item> </menu>

Menu文件，menu3.xml:

<?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/item07" android:title="Tab3 M1"></item> <item android:id="@+id/item08" android:title="Tab3 M2"></item> <item android:id="@+id/item09" android:title="Tab3 M3"></item> </menu>
