I can use android:gravity="bottom|center_horizontal" in xml on a textview to get my desired results but I need to do this programmatically.
My textview is inside a tablerow if that matters in a relativelayout.
I have tried:
CODE:........
But if I understand that correctly, that would apply it to the tablerow? not the textview?

I have ScrollView with RelativeLayout as a child of ScrollView. I am trying through JAVA code to set Layout_Gravity to CENTER so my RelativeLayout is centered (horizontally and vertically) in the middle of ScrollView (that covers whole screen).This works fine in XML and produces desired result, but when I try to do this programmatically, it seems there is no way to set Layout_Gravity of RelativeLayout. I tried using LayoutParams, but couldn't find anything there that would help me to center RelativeLayout in the middle. So, am I missing something or this simply can't be done?

I'm unable to change the layout_gravity of a Button programmatically, does anybody know how to do this?The gravity attribute is easily changed using Button.gravity(), Ie it changes the gravity of the text inside the button I cannot change the gravity of the button itself. I also cannot seem to find this in any of the layout params contructors.
View 2 Replies View RelatedHas anyone tried to write his own implementation of ViewGroup with some TextViews in it? I have a problem, that TextViews in such an implementation don't respect gravity attribute (TextView.setGravity(Gravity.CENTER);) and text is positioned in the top left corner.
If enyone is interested, I just overwrote method onMeasure() (for all my TextViews) and changed call from super.onMeasure() to setMeasuredDimension(int, int) and gravity started to work normally.

I am desperately trying to set TextView attributes of cells within a table programmatically but can't get this to work! Whenever I set layout properties, the field will simply not appear (but not give any error or exception). I boilded this down to this simple example:

This will show three fields, but when you uncomment the five commented line, then NOTHING will appear. Why is that so? Why does setting layout parameters cause my TextView's to not appear? I'm stuck! What am I missing?

The line beginning 'log.d' was the part I was working on, trying to get it to print out the contents of the 2nd text view in the first row, but I can only get as far as selecting the tablerow using "getChildAt(i)".
Trying "getChildAt(0).getChildAt(1)" doesn't select the textview as I would have expected it to; says that it's a View and as such, doesn't have this method - though unless I'm mistaken, aren't tablerows ViewGroups, which do have this method? code...

I know we can set the following value to the anroid:gravity and android:layout_gravity :
center
center_vertical
center_horizontal , etc.
But i am confused regarding these both. what is the difference between the usage of android:gravity and android:layout_gravity?
What is the difference between those attributes? According to the documentation of R.attr, there isn't any difference (doc text is exactly the same, see http://developer.android.com/reference/android/R.attr.html), but apparently, that's simply not true. For example, the gravity attribute can be used on EditText to set the text alignment (e.g. left, center, right).
I often found that neither of them work to align a view at all. For example, I need to float two text views in a relative layout, one going to the left below a title bar, the other going to the right below the title bar. So what I did was this:
CODE:...............
That doesn't work, however. The left text is indeed aligned to the left inside its parent (the relative layout), but the right text is not aligned to the right; instead, it's placed directly to the right of the left text.
I know there are tons of questions about this already floating around SO but I've read a bunch of them and still cannot get my 3rd column to align to the right.
CODE:........................
I know this question is definitely solved somewhere many times already, please enlighten me if you know of their existence,
Quick rundown:
I want to compute from a 3 axis accelerometer the gravity component on each of these 3 axes.
I have used 2 axes free body diagrams to work out the accelerometer's gravity component in the world X-Z, Y-Z and X-Y axes. But the solution seems slightly off, it's acceptable for extreme cases when only 1 accelerometer axis is exposed to gravity, but for a pitch and roll of both 45 degrees, the combined total magnitude is greater than gravity (obtained by Xa^2+Ya^2+Za^2=g^2; Xa, Ya and Za are accelerometer readings in its X, Y and Z axis).
More detail:
The device is a Nexus One, and have a magnetic field sensor for azimuth, pitch and roll in addition to the 3-axis accelerometer.In the world's axis (with Z in the same direction as gravity, and either X or Y points to the north pole, don't think this matters much?), I assumed my device has a pitch (P) on the Y-Z axis, and a roll (R) on the X-Z axis. With that I used simple trig to get:
Sin(R)=Ax/Gxz
Cos(R)=Az/Gxz
Tan(R)=Ax/Az
There is another set for pitch, P.Now I defined gravity to have 3 components in the world's axis, a Gxz that is measurable only in the X-Z axis, a Gyz for Y-Z, and a Gxy for X-Y axis.Gxz^2+Gyz^2+Gxy^2=2*G^2 the 2G is because gravity is effectively included twice in this definition. Oh and the X-Y axis produce something more exotic I'll explain if required later.From these equations I obtained a formula for Az, and removed the tan operations because I don't know how to handle tan90 calculations (it's infinity?).So my question is, anyone know whether I did this right/wrong or able to point me to the right direction?

Gravity Tow is an addictive and challenging action game which could be best described as 'Reverse Doodle Jump.' It has an online high-score where you can compare your results to others. The aim of the game is to pull up the waste container as high as possible by activating gravity fields.
After the second interplanetary war, you work as a waste disposal manager and shoot containers with nuclear waste into the general direction of planet Dork 42.

It is available now from Android Market: Gravity Tow
It requires Android 1.6 or higher, works also on older phones.
The Samsung Gravity Smart has extremely limited internal memory. The new Playstore App automatically installs itself every time I download another app. Then, I have to remove the Playstore app before I do anything else, because the Playstore app has consumed all of the memory.
Isn't there something that I can do to stop the Playstore app from installing itself?
why my Android's internal storage is full. I don't think I have anything on there except for the 18 stock apps I have (including apps like titanium backup, and Link2SD that came with my ROM). I've gotten rid of all the bloatware on the phone, deleted most of my cache, and moved all of my downloaded apps to the SD card. I've even gone as far as to replace the web browser with Opera mini (and put it on the SD card), and prevented the device from installing a 10 MB update for the google play store. Even though the phone only has 14 MB (138/152 MB), I would think that would be more than enough to receive text messages. The phone doesn't even want me to do that.
I do have a few thoughts as to what could be causing this problem. First off, even after I've deleted an app via titanium backup, the app still appears in titanium backup with a line through it. This leads me to believe that the app still has data left on the phone. Second, I'm thinking Link2SD isn't actually moving all of the app to the SD card. In that case, I guess I don't have any choice but to remove all of my extra apps.
I actually have one solution that may or may not work. If I could somehow make the device treat my extra (32 GB) SD card into thinking it's the phone's external storage, then I wouldn't have to worry about overloading it at all. Would this work flawlessly?
Here's some extra information that may or may not be useful.

I have a ListView that contains an Image on the left of two vertically-oriented TextViews using a RelativeLayout. When both TextViews have text it looks fine. Sometimes the TextView on the bottom won't have any text, and the problem is that the entire layout is several pixels above where it should be because it still reserves that space for text when there isn't any making the entire list have annoying blank gaps. I remember seeing an example of where someone made the layout not reserve the space, but I can't remember how he did it.
