Android TahHost的使用2 不继承TabActivity
Layout的设计，其实有我这里直接拖了一个TabHost控件，然后在每个Tab中放一个Button。
文件名为activity_tab_host.xml.
<RelativeLayout xmlns:android=
"http://schemas.android.com/apk/res/android"
xmlns:tools=
"http://schemas.android.com/tools"
android:layout_width=
"match_parent"
android:layout_height=
"match_parent"
android:paddingBottom=
"@dimen/activity_vertical_margin"
android:paddingLeft=
"@dimen/activity_horizontal_margin"
android:paddingRight=
"@dimen/activity_horizontal_margin"
android:paddingTop=
"@dimen/activity_vertical_margin"
tools:context=
".TabHostActivity"
>
<TabHost
android:id=
"@+id/tabhost"
android:layout_width=
"match_parent"
android:layout_height=
"match_parent"
android:layout_alignParentLeft=
"true"
android:layout_alignParentTop=
"true"
>
<LinearLayout
android:layout_width=
"match_parent"
android:layout_height=
"match_parent"
android:orientation=
"vertical"
>
<TabWidget
android:id=
"@android:id/tabs"
android:layout_width=
"match_parent"
android:layout_height=
"wrap_content"
>
</TabWidget>
<FrameLayout
android:id=
"@android:id/tabcontent"
android:layout_width=
"match_parent"
android:layout_height=
"match_parent"
>
<LinearLayout
android:id=
"@+id/tab1"
android:layout_width=
"match_parent"
android:layout_height=
"match_parent"
>
<Button
android:id=
"@+id/button1"
android:layout_width=
"wrap_content"
android:layout_height=
"wrap_content"
android:text=
"Fist Tab Content"
/>
</LinearLayout>
<LinearLayout
android:id=
"@+id/tab2"
android:layout_width=
"match_parent"
android:layout_height=
"match_parent"
>
<Button
android:id=
"@+id/button1"
android:layout_width=
"wrap_content"
android:layout_height=
"wrap_content"
android:text=
"Second Tab Content"
/>
</LinearLayout>
<LinearLayout
android:id=
"@+id/tab3"
android:layout_width=
"match_parent"
android:layout_height=
"match_parent"
>
<Button
android:id=
"@+id/button1"
android:layout_width=
"wrap_content"
android:layout_height=
"wrap_content"
android:text=
"Third Tab Content"
/>
</LinearLayout>
</FrameLayout>
</LinearLayout>
</TabHost>
</RelativeLayout>

需要注意的是TabHost必须包含一个 TabWidget和一个FrameLayout。而且TabWidget的id属性必须为 @android:id/tabs，FrameLayout的id属性必须为 @android:id/tabcontent。
下面TabHostActivity.java文件为：
public
class
TabHostActivity extends Activity {
@Override
protected
void
onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tab_host);
TabHost tabHost = (TabHost)findViewById(R.id.tabhost);
tabHost.setup();
tabHost.addTab(tabHost.newTabSpec(
"tab1"
)
.setIndicator(
"First Tab"
)
.setContent(R.id.tab1));
tabHost.addTab(tabHost.newTabSpec(
"tab2"
)
.setIndicator(
"Second Tab"
)
.setContent(R.id.tab2));
tabHost.addTab(tabHost.newTabSpec(
"tab3"
)
.setIndicator(
"Third Tab"
)
.setContent(R.id.tab3));
}
}
