每一个tab对应一个widget。

package com.eoemobile.book.ex_widgetdemo;
import android.app.TabActivity;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.widget.TabHost;
public class TabDemoActivity extends TabActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setTitle("TabDemoActivity");
TabHost tabHost = getTabHost();
LayoutInflater.from(this).inflate(R.layout.tab_demo,
tabHost.getTabContentView(), true);
tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("tab1")
.setContent(R.id.view1));
tabHost.addTab(tabHost.newTabSpec("tab3").setIndicator("tab2")
.setContent(R.id.view2));
tabHost.addTab(tabHost.newTabSpec("tab3").setIndicator("tab3")
.setContent(R.id.view3));
}
}
