时光毁灭记忆、已成空白 提交于 2019-11-30 23:05:54
I have an issue I have not been able to figure out and it is only happening on devices running <2.1. It works fine on android 2.2.

Existing patches for android tabwidget to allow tabs on left-hand side?

纵饮孤独 提交于 2019-11-30 17:14:40
问题 My employer is having me work on an android application with very specific UI requirements. Specifically, we need an interface that looks exactly like a TabWidget interface. However, having the tabs on the left hand side is an absolute must. We aren't going to be deploying this application to any android phones, its for an in house device, and as such don't have any problem violating any design considerations that the android platform might have. We already have a working prototype that hacks

Controlling Tab colour-state / size in a TabActivity?

独自空忆成欢 提交于 2019-11-30 07:15:08
问题 Ok, this is driving me nuts - I've searched all of the references and examples I can find and I still seem to be missing something really obvious. These are the tabs for a 7-day TV Guide (not normally with the red arrow, obviously :) )... What I need to know is what is the object (View or Drawable I assume) that makes up the main body/background of a Tab itself? (as indicated by the red arrow) and how do I access it or have it automatically change its state colour to a list of my choice? Also

How to implement horizontally scrollable tabs?

為{幸葍}努か 提交于 2019-11-30 05:21:19
I'm trying to implement this application. At the moment I have designed tabs on it and since I have more than 7 tabs it looks too congested. How can I design it so that the tabwidget is scrollable horizontally. I have seen this design on few of the apps at the market but no clue how to implement this in my app. One app I saw had a horizontal scrollview where it scrolls on its own and when you press the particular image/button it displays some content. It didn't seem to be tabs I guess. So does anyone have an idea of this? Please check out Jake Wharton's ViewPager app. That is exactly what you

Change text color and selector in TabWidget

本秂侑毒 提交于 2019-11-30 05:13:57
I've a TabWidget , independently of the ÀctionBar , in a FragmentTabHost`. I want to customize the look and feel of the TabWidget but I don't get it. My intention is to change the text color and the selector color, as you can see in the image I can change the background of the TabWidget .

In this way: <TabWidget android:id="@android:id/tabs" android:layout_width="match_parent" android:layout_height="wrap_content" android
