如何在Android的标签小部件中添加间距？

Question

I'd like to add extra spacing on the sides and between tabs on the tab widget, but padding and margins dont seem to make any difference. I also played with setting the divider, tab strip left and right drawables, which didn't seem to make any difference either.

Trying to make the tabs look like this:

Answer 1

You can use this code to do that

TabWidget widget = getTabWidget();
final int tabChildrenCount = widget.getChildCount();
LinearLayout.LayoutParams currentLayout;
for (int i = 0; i < tabChildrenCount; i++) {
    currentLayout = (LinearLayout.LayoutParams) widget.getChildAt(i).getLayoutParams();
    if (i == 0) {
        currentLayout.setMargins(10, 0, 5, 0);
    } else if (i == (tabChildrenCount - 1)) {
        currentLayout.setMargins(5, 0, 10, 0);
    } else {
        currentLayout.setMargins(5, 0, 5, 0);
    }
    currentLayout.height = 40;
}
widget.requestLayout();

You need to set the divider between the Tab widgets. Take a look at dividers between TabWidgets

The Google IO schedule app has tabs that look just like yours. I would check out that app and browse their source code: http://code.google.com/p/iosched/ (the middle screenshot has the tabs)
