<!-- TabHost必须包含一个 TabWidget和一个FrameLayout-->
<TabHost android:id="@+id/tabhost"

<TabWidget android:id="@android:id/tabs"

android:layout_width="fill_parent"
android:layout_height="wrap_content">
</TabWidget>
<!-- FrameLayout的id属性必须为 @android:id/tabcontent-->
<FrameLayout android:id="@android:id/tabcontent"
android:layout_width="fill_parent"

<TextView android:id="@+id/view1"

android:layout_height="fill_parent"/>
<TextView android:id="@+id/view2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
<TextView android:id="@+id/view3"
android:layout_width="fill_parent"

</FrameLayout>
</LinearLayout>
</TabHost>
</LinearLayout>
public class TagHostTest2 extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // 获取TabHost对象 TabHost tabHost = (TabHost) findViewById(R.id.tabhost); // 如果没有继承TabActivity时,通过该种方法加载启动tabHost tabHost.setup(); tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("第一个标签", getResources().getDrawable(R.drawable.icon)).setContent( R.id.view1)); }
其中,.setContent(R.id.view2)) 可传入intent参数,此时 应该继承acitivityGroup,
public class TabMergeActivity extends TabActivity{ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); TabHost tabHost = getTabHost(); TabSpec spec; Resources res = getResources(); Intent intent; //第一个TAB intent = new Intent(this,A.class); spec = tabHost.newTabSpec("tab1") .setIndicator("Tab1", res.getDrawable(android.R.drawable.ic_media_play)) .setContent(intent); tabHost.addTab(spec);
