I've looked through numerous similar questions here at SO, but nothing helps. I have a hierarchy of different nested layouts, all have android:layout_width="fill_parent" , and the inner-most layout has android:layout_width="wrap_content - I need to align it at the center (horizontally). How do I do that? Update: : I've found the cause of the problem - if I put the inner LinearLayout into RelativeLayout with android:layout_width="fill_parent" , it still wraps it's content. The TableRow, however, is really filling the screen. <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android=

I want to create a progress bar (intermediate progress bar) similar to gmail app which change colours.I am able to this by keeping and updating progress_indeterminate_horizontal.xml from sdk/platforms. I don't want to use animation (multi colour images). I want to achieve this using xml (i want use gradient). Any help will be appreciated. Thanks in advance JASON G PETERSON Here's my implementation: Draws an animated rainbow gradient. Cool, if I do say so myself. It's not XML-based, but could be made to be, and it does use gradients. Perhaps it will give you some ideas. Setup: pb = (ProgressBar

I'm trying to determine the real dimension in pixels of some UI elements ! Those elements are inflated from a .xml file and are initialized with dip width and height so that the GUI will eventually support multiple screen size and dpi ( as recommended by android specs ). <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="150dip" android:orientation="vertical"> <ImageView android:id="@+id/TlFrame" android:layout_width="110dip" android:layout_height="90dip" android:src="@drawable/timeline_nodrawing" android:layout

I would like to know The difference between MotionEvent.getRawX and MotionEvent.getX in android as one is numeric and the other is float?Whats the need to have both of these types? MotionEvent will sometimes return absolute X and Y coordinates relative to the view, and sometimes relative coordinates to the previous motion event. getRawX() and getRawY() that is guaranteed to return absolute coordinates, relative to the device screen. While getX() and getY() , should return you coordinates, relative to the View, that dispatched them. => rawX = motionEven.getX() + touchableButton.getX() + layout3

I have a sliding drawer menu in an activity, which has an actionbar with some tabs on it. I'd like to get the sliding drawer to slide over the tabs , not below them. This is what it looks like right now... Any ideas on how this could be done? Note: I understand that I might be breaking some conventions and UI patterns here, and if it does not work at all, I'll look at alternatives. But I'd like to get this working first. EDIT: See the below screen shot of the Google Play Music app that does exactly what I need. See @CommonsWare's answer below where he does agree that I might be breaking

Can anyone tell me if there's any difference between using runOnUiThread() versus Looper.getMainLooper().post() to execute a task on the UI thread in Android?? About the only thing I can determine is that since runOnUiThread is a non-static Activity method, Looper.getMainLooper().post() is more convenient when you need to code something in a class that can't see the Activity (such as an interface). I'm not looking for a discussion on WHETHER something should be executed on the UI thread, I get that some things can't and a great many things shouldn't, however some things (like starting up an

Just checked how to make menu with DrawerLayout here . But left side menu is moving on the front of main content. How can I set it to menu and main content move side by side(menu is pushing content to the right)? If you dont want to use third-party libraries , you can implement it yourself just overriding the onDrawerSlide from the ActionBarDrawerToggle. There you can translate your framelayout view based on the opening % of your drawer. Example with code: <?xml version="1.0" encoding="utf-8"?> <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
