Creating an Input Method. An input method editor (IME) is a user control that enables users to enter text.
Android provides an extensible input-method framework that allows applications to provide users alternative input methods, such as on-screen keyboards or even speech input. After installing the desired IMEs, a user can select which one to use from the system settings, and use it across the entire system; only one IME may be enabled at a time. To add an IME to the Android system, you create an Android application containing a class that extends InputMethodService. In addition, you usually create a "settings" activity that passes options to the IME service. You can also define a settings UI that's displayed as part of the system settings. This guide covers the following: The IME lifecycle Declaring IME components in the application manifest The IME API Designing an IME UI Sending text from an IME to an application Working with IME subtypes The IME Lifecycle Figure 1.

Without Gingerbread Support. Styling tabs in the Android action bar. I’m currently in the process of putting the finishing touches on the Android version of Find My Train. Since design detail is a major focus in the app, I’m delving deeper into some of the UI elements than might be done on a typical app. My most recent change was to tweak the color of the tabs on the action bar to match the color scheme of the app. This turned out to be surprisingly tricky, so I’m documenting it here.
The default color looked like this: As you can see, the little indicator of the active tab is a blue color that doesn’t really go along with the rest of the app. However, it doesn’t go into much detail about how to actually style the tabs.

In this blog post, we will continue that effort, creating another theme and allowing dynamic switching of themes during runtime. Ideally, if we treat theme as a configuration, we should be able to specify theme-specific resources under a ‘theme-qualifier’ resources directory, e.g. values-dark for dark theme resources and values-light for light theme resources. Unfortunately, this is not yet an option at the time of this post. So how should we specify resources for multiple themes? GitHub - daimajia/AndroidSwipeLayout: The Most Powerful Swipe Layout!
