android TabHost选项卡示例

1. 继承TabActivity，从TabActivity中用getTabHost()方法获取TabHost.各个Tab中的内容在布局文件中定义即可。

tabactivity.xml:

<?xml version="1.0" encoding="utf-8"?>

2. 不继承TabActivity，在布局文件中定义TabHost即可，但是TabWidget的ID必须是@android:id/tabs，FrameLayout的ID必须是@android:id/tabcontent，TabHost的ID可自定义。

tabxml.xml:

<?xml version="1.0" encoding="utf-8"?>

MyTabActivity.java 文件：

package com.example.baseexample;import android.app.TabActivity;import android.os.Bundle;import android.view.LayoutInflater;import android.widget.TabHost;public class MyTabActivity extends TabActivity {private TabHost myTabHost ;protected void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);myTabHost = this.getTabHost();LayoutInflater.from(this).inflate(R.layout.tabactivity, myTabHost.getTabContentView(),true);myTabHost.addTab(myTabHost.newTabSpec("选项卡1").setIndicator("选项卡1",getResources().getDrawable(R.drawable.ic_launcher)).setContent(R.id.firstTab));myTabHost.addTab(myTabHost.newTabSpec("选项卡2").setIndicator("选项卡2",getResources().getDrawable(R.drawable.ic_launcher)).setContent(R.id.secondTab));myTabHost.addTab(myTabHost.newTabSpec("选项卡3").setIndicator("选项卡3",getResources().getDrawable(R.drawable.ic_launcher)).setContent(R.id.thirdTab));}}

TabXmlActivity.java文件：

package com.example.baseexample;import android.app.Activity;import android.os.Bundle;import android.widget.TabHost;public class TabXmlActivity extends Activity {protected void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);setContentView(R.layout.tabxml);TabHost tabHost = (TabHost)findViewById(R.id.tabhost);tabHost.setup();tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("tab1",getResources().getDrawable(R.drawable.ic_launcher)).setContent(R.id.view1));tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("tab2",getResources().getDrawable(R.drawable.ic_launcher)).setContent(R.id.view2));tabHost.addTab(tabHost.newTabSpec("tab3").setIndicator("tab3",getResources().getDrawable(R.drawable.ic_launcher)).setContent(R.id.view3));}}
