Answer 1

        TabHost tabHost;
public void onCreate(final Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        tabHost = getTabHost();       
        TabSpec spec;
                 spec=tabHost.newTabSpec("Tab1")
        .setIndicator("Tab1")
        .setContent(R.id.  );
        tabHost.addTab(spec);

Answer 2

public class tab1 extends Activity { @Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
TextView tv = new TextView(this);
tv.setText("tab2");
this.setContentView(tv);
}}public class TabHost_3 extends TabActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.main);
        TabHost tabhost = getTabHost();
        TabSpec ts;
        Intent intent;
        intent = new Intent().setClass(this, tab1.class);
        ts = tabhost.newTabSpec("Tab1").setIndicator("tab1").setContent(intent);
        tabhost.addTab(ts);
    }
}这是里是用Intent实现的

Activity:
import android.app.TabActivity;
import android.os.Bundle;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;public class Main extends TabActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        TabHost th = getTabHost();
        TabSpec ts;
        ts = th.newTabSpec("Tab1").setIndicator("tab1").setContent(R.id.tab1);
        th.addTab(ts);
        ts = th.newTabSpec("Tab2").setIndicator("tab2").setContent(R.id.tab2);
        th.addTab(ts);
        ts = th.newTabSpec("Tab3").setIndicator("tab3").setContent(R.id.tab3);
        th.addTab(ts);
    }
}Main:
<?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:id="@+id/linearLayout1" android:layout_height="fill_parent" android:orientation="vertical">
            <TabWidget android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@android:id/tabs"></TabWidget>
            <FrameLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@android:id/tabcontent">
                <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/tab1"></LinearLayout>
                <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/tab2"></LinearLayout>
                <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/tab3"></LinearLayout>
            </FrameLayout>
        </LinearLayout>
    </TabHost>
