1. 最简单的TabHost,Tab来自于layout下的元素 (只从1个Layout中取数据)
(1)效果图
(2)代码
1)tab_demo.xml
[xhtml]view plaincopy
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView android:id="@+id/tab_demo_tv1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="tab_demo_tv1"
/>
<TextView android:id="@+id/tab_demo_tv2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="tab_demo_tv2"
/>
<TextView android:id="@+id/tab_demo_tv3"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="tab_demo_tv3"
/>
</FrameLayout>
2)TabDemo.java
[java]view plaincopy
public class TabDemo extends TabActivity {
private TabHost tabHost;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
tabHost = getTabHost();
LayoutInflater.from(this).inflate(R.layout.tab_demo, tabHost.getTabContentView(), true);
tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("Tab1", null).setContent(R.id.tab_demo_tv1));
tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("Tab2", null).setContent(R.id.tab_demo_tv2));
tabHost.addTab(tabHost.newTabSpec("tab3").setIndicator("Tab3", null).setContent(R.id.tab_demo_tv3));
setContentView(tabHost);
}
}
2. TabHost绑定动态View(从2个Layout中取数据)
(1)效果图
(2)代码
1)tab_map.xml
[xhtml]view plaincopy
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/tab_map_id"
>
</FrameLayout>
2)tab_hs.xml
[xhtml]view plaincopy
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/tab_hs_id"
>
<TextView android:id="@+id/tab_hs_tv"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</FrameLayout>
3)MapView.java
[java]view plaincopy
public class MapView extends View {
public MapView(Context context) {
super(context);
}
protected void onDraw(Canvas canvas) {
Paint p = new Paint();
canvas.drawBitmap(BitmapFactory.decodeResource(getResources(), R.drawable.icon), 0, 0, p);
}
}
4)TabDemo.java
[java]view plaincopy
public class TabDemo extends TabActivity {
private TabHost tabHost;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
tabHost = getTabHost();
createTabSpec_map();
createTabSpec_hs();
setContentView(tabHost);
}
private void createTabSpec_map() {
LayoutInflater inflater_tab1 = LayoutInflater.from(this);
inflater_tab1.inflate(R.layout.tab_map, tabHost.getTabContentView());
FrameLayout frameLayout = (FrameLayout) findViewById(R.id.tab_map_id);
MapView mv = new MapView(this);
frameLayout.addView(mv);
TabHost.TabSpec tabSpec_map = tabHost.newTabSpec("map view");
tabSpec_map.setIndicator("map view", null);
tabSpec_map.setContent(R.id.tab_map_id); // 动态绑定基于图片的View(通过一个Layout绑定)
tabHost.addTab(tabSpec_map);
}
private void createTabSpec_hs() {
LayoutInflater inflater_tab2 = LayoutInflater.from(this);
inflater_tab2.inflate(R.layout.tab_hs, tabHost.getTabContentView());
TabHost.TabSpec tabSpec_hs = tabHost.newTabSpec("hs view");
tabSpec_hs.setIndicator("hs view");
tabSpec_hs.setContent(R.id.tab_hs_id); // 绑定一个新的Layout
tabHost.addTab(tabSpec_hs);
updateTabSpec_hs();
}
private void updateTabSpec_hs() {
TextView tv = (TextView) findViewById(R.id.tab_hs_tv);
tv.setText("This is tab2");
}
}
