I want to implement tabwidget with several tabs, each one of them represents data from single data source which can change dynamicaly, so i cant use several activities, because as far as i understand Activity is more like an application which is not exists while its hidden. So ive created tabwidget like this:
<ScrollView android:id ="@+id/settings_view"
android:layout_width="match_parent"
android:layout_height="match_parent">
</ScrollView>
<ScrollView android:id="@+id/maps_view"
android:layout_width="match_parent"
android:layout_height="match_parent">
</ScrollView>
<EditText android:id="@+id/statistics_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:singleLine="false"
android:layout_marginLeft="10dip"
android:layout_marginRight="10dip">
</EditText>
<RelativeLayout android:id="@+id/about_view"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="@+id/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:tint="#55ff0000"
android:src="@drawable/main"
android:layout_centerInParent="true"/>
<TextView
android:id="@+id/appname"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/app_name"
android:layout_below="@id/icon"
android:layout_centerInParent="true"/>
<TextView
android:id="@+id/version"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/appname"
android:layout_centerInParent="true"/>
<TextView
android:id="@+id/site"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/app_site"
android:layout_below="@id/version"
android:layout_centerInParent="true"/>
<TextView
android:id="@+id/copyright"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/app_copyright"
android:layout_below="@id/site"
android:layout_centerInParent="true"/>
</RelativeLayout>
<RelativeLayout android:id ="@+id/gatewaylist_view"

android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dip"

<LinearLayout

android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"

</LinearLayout>
and i initialize my application like this
public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main);
Resources res = getResources(); // Resource object to get Drawables
TabHost tabHost = getTabHost(); // The activity TabHost
tabHost.addTab(tabHost.newTabSpec("tab_gatewaylist").setIndicator("",res.getDrawable(R.drawable.ic_tab_favorites)).setContent(R.id.ga开发者_开发问答tewaylist_view));
tabHost.addTab(tabHost.newTabSpec("tab_gatewayparams").setIndicator("",res.getDrawable(R.drawable.ic_tab_gatewayparams)).setContent(R.id.gatewayparams_view));
tabHost.addTab(tabHost.newTabSpec("tab_videofield").setIndicator("",res.getDrawable(R.drawable.ic_tab_videofield)).setContent(R.id.videofield_view));
tabHost.addTab(tabHost.newTabSpec("tab_maps").setIndicator("",res.getDrawable(R.drawable.ic_tab_maps)).setContent(R.id.maps_view));
tabHost.addTab(tabHost.newTabSpec("tab_statistics").setIndicator("",res.getDrawable(R.drawable.ic_tab_statistics)).setContent(R.id.statistics_view));
tabHost.addTab(tabHost.newTabSpec("tab_settings").setIndicator("",res.getDrawable(R.drawable.ic_tab_settings)).setContent(R.id.settings_view));
tabHost.addTab(tabHost.newTabSpec("tab_about").setIndicator("",res.getDrawable(R.drawable.ic_tab_about)).setContent(R.id.about_view));
tabHost.setCurrentTab(0);
its works ok , but i wonder if i can separate definitions fro different tabs into separate xml files. Ive tried to do this but application crashes while trying to add corresponding tab. Thanks in advance.
Have you tried using the <include /> element? http://developer.android.com/resources/articles/layout-tricks-reuse.html
this way you can put the single xml definitions in different files and include them in the main one.
