i'm trying to use TabHost and TabWidget in my Android application. This is my layout main.xml:
<TabHost
android:id="@+id/mainTabHost"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="65px"/>
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:id="@+id/contentTags"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
</LinearLayout>
<LinearLayout
android:id="@+id/contentPreferences"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
</LinearLayout>
</FrameLayout>
</TabHost>
And my code:
final TabHost mainTabHost = (TabHost) this.findViewById(R.id.mainTabHost);
mainTabHost.setup();
final TabHost.TabSpec tabSpecTags = mainTabHost.newTabSpec("tabTags");
tabSpecTags.setIndicator(this.getString(R.string.tab_name_tags));
tabSpecTags.setContent(R.id.contentTags);
mainTabHost.addTab(tabSpecTags);
final TabHost.TabSpec tabSpecPreferences = mainTabHost.newTabSpec("tabPreferences");
tabSpecPreferences.setIndicator(this.getString(R.string.tab_name_preferences));
tabSpecPreferences.setContent(R.id.contentPreferences);
mainTabHost.addTab(tabSpecPreferences);
The problem is that i do not want my tabs to be so tall (65px). However, if i set the la开发者_高级运维yout_height of the TabWidget to e.g. 30px, i can't see the tab labels (indicator) on the tabs at all.
Seems like there is a "minimum required" height for the TabWidget (65px?) and the indicator is positioned at the bottom of this 65px?
Is there a way to adjust the positioning of the indicator?
Thanks!

Note that the techniques for doing this won't necessarily be reliable in future Android releases, if they change up how a TabHost
is constructed.

Starting with API Level 4 (a.k.a., Android 1.6), TabHost.TabSpec
accepts a View
as the indicator via setIndicator()
. I haven't tried it, but it may give you greater control over the layout of an individual tab's indicator.
i see... when u addTab, usually we use setIndicator like this: QTabHost.addTab(QTabHost.newTabSpec("tab_test2").setIndicator("TAB 2").bla bla....
u can use TextView to replace "TAB 2", became like this:
tview=new TextView(this); tview.setText("Title here"); QTabHost.addTab(QTabHost.newTabSpec("tab_test2").setIndicator(tview).bla bla....
all u need is just modify the textview. Thanks... ^^
int iH = getTabWidget().getLayoutParams().height;
for (int i = 0; i < tabHost.getTabWidget().getChildCount(); i++) {
tabHost.getTabWidget().getChildAt(i).getLayoutParams().height = iH;
}
for (int i = 0; i < 4; i++) {
tabhost.getTabWidget().getChildAt(i).getLayoutParams().height = 50;
}
by using this we can do very easily
