1、通过findViewById
tabs1.xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView android:id="@+id/view1"
android:background="@drawable/blue"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="@string/tabs_1_tab_1"/>
<TextView android:id="@+id/view2"
android:background="@drawable/red"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="@string/tabs_1_tab_2"/>
<TextView android:id="@+id/view3"
android:background="@drawable/green"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="@string/tabs_1_tab_3"/>
</FrameLayout>
java文件:
TabHost tabHost = getTabHost();
LayoutInflater.from(this).inflate(R.layout.tabs1, 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));
效果:
2、Content By Factory
public class Tabs2 extends TabActivity implements TabHost.TabContentFactory {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final TabHost tabHost = getTabHost();
tabHost.addTab(tabHost.newTabSpec("tab1")
.setIndicator("tab1", getResources().getDrawable(R.drawable.star_big_on))
.setContent(this));
tabHost.addTab(tabHost.newTabSpec("tab2")
.setIndicator("tab2")
.setContent(this));
tabHost.addTab(tabHost.newTabSpec("tab3")
.setIndicator("tab3")
.setContent(this));
}
/** {@inheritDoc} */
public View createTabContent(String tag) {
final TextView tv = new TextView(this);
tv.setText("Content for tab with tag " + tag);
return tv;
}
}
效果:
3、Content By Intent
List8.java
public class List8 extends Activity{}
public class Tabs3 extends TabActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final TabHost tabHost = getTabHost();
tabHost.addTab(tabHost.newTabSpec("tab1")
.setIndicator("list")
.setContent(new Intent(this, List1.class)));
tabHost.addTab(tabHost.newTabSpec("tab2")
.setIndicator("photo list")
.setContent(new Intent(this, List8.class)));
// This tab sets the intent flag so that it is recreated each time
// the tab is clicked.
tabHost.addTab(tabHost.newTabSpec("tab3")
.setIndicator("destroy")
.setContent(new Intent(this, Controls1.class)
.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)));
}
}
效果:
4、增加holo主题
<activity android:name=".view.Tabs4" android:label="Views/Tabs/4. Non Holo theme"
android:theme="@android:style/Theme">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.SAMPLE_CODE"/>
</intent-filter>
</activity>
效果:
5、可滑动Tab页
tabs_scroll.xml
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="5dp">
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="none">
<TabWidget
android:id="@android:id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</HorizontalScrollView>
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="5dp" />
</LinearLayout>
</TabHost>
Tabs5.java
public class Tabs5 extends TabActivity implements TabHost.TabContentFactory {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tabs_scroll);
final TabHost tabHost = getTabHost();
for (int i=1; i <= 30; i++) {
String name = "Tab " + i;
tabHost.addTab(tabHost.newTabSpec(name)
.setIndicator(name)
.setContent(this));
}
}
/** {@inheritDoc} */
public View createTabContent(String tag) {
final TextView tv = new TextView(this);
tv.setText("Content for tab with tag " + tag);
return tv;
}
}
