In Android, when using a TabHost with a TabWidget, the tabs are, by default, horizontally centered within the TabWidget. To left-align the tabs, you can achieve this by customizing the TabWidget layout and setting appropriate attributes.

Here's how you can left-align the tabs for a TabHost using a TabWidget:

  1. Define a custom layout for the TabWidget: Create a new XML layout file for the TabWidget with the desired left-align layout. For example, you can create a file named tab_widget_layout.xml:

    <!-- res/layout/tab_widget_layout.xml --> <LinearLayout xmlns:android="" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal" android:layout_gravity="start" android:gravity="start"> </LinearLayout>

    In this custom layout, we use a LinearLayout with horizontal orientation and set android:layout_gravity="start" and android:gravity="start" to left-align the tabs.

  2. Update the TabWidget in the TabHost layout: In your main layout file where you define the TabHost, set the android:tabWidgetLayout attribute to point to your custom tab_widget_layout.xml:

    <TabHost xmlns:android="" android:id="@android:id/tabhost" android:layout_width="match_parent" android:layout_height="match_parent"> <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" android:tabWidgetStyle="@style/CustomTabWidgetStyle" /> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="match_parent" android:layout_height="match_parent" /> </LinearLayout> </TabHost>
  3. Define a custom style for the TabWidget (optional): If you want to further customize the appearance of the TabWidget, you can create a custom style and apply it to the TabWidget.

    In styles.xml, define your custom style:

    <resources> <!-- ... other styles ... --> <style name="CustomTabWidgetStyle" parent="@android:style/Widget.TabWidget"> <!-- Add any additional custom styling attributes here --> </style> </resources>

    Apply the custom style to the TabWidget in the TabHost layout by using android:tabWidgetStyle="@style/CustomTabWidgetStyle".

With these steps, the TabWidget in the TabHost will be left-aligned, and the tabs will appear on the left side of the TabWidget. You can further customize the appearance of the tabs by adjusting the custom layout or custom style as needed.
