I can't seem to find anywhere a way to programmatically change the the alignment of the button.
In the XML it is simply layout_gravity="Center" or something.
How do we do this in the code?
LayoutParams do not seem to cater for this.

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.

In the Hierarchy Viewer the text field has a absolute_y of 30 while the button has 32. Please see screenshots of the Hierarchy Viewer here: http://picasaweb.google.com/sj1981/Android

I'm trying to create standard button in android with a background and some text in front but some fairly specific alignment. I want the text to be centered vertically and on the left with 20dp of padding. The alignment works but the padding doesn't. I know I could probably get the desired effect by putting a few spaces in the text but that seems like a hack and next I want to do a similar thing but with the text at the top so I would prefer a more elegant solution. Here's what I have:
<Button
android:layout_width="312dp"
android:layout_height="95dp"
android:id="@+id/gv_music_button"
android:text="Music"
android:textSize="30sp"
android:paddingLeft="20dp"
android:gravity="left|center_vertical"
/>
I have this resource file for colors
CODE:..................
And this method that gets called when the user clicks one of four colored Buttons
CODE:.................
The problem is the color of the Button doesn't change when pressed. I stepped with a debugger and it actually reaches the right points in the method, so that's not an issue. I think the problem is in pressedBtn.setBackgroundResource(newColor) but I can't understand why. Anyway, if you have a better solution to change a button color when pressed and, after a half second, change back to original color, let me know.

View 2 Replies View RelatedI am reading in some data from a REST api and need to generate some buttons based on the information the app receives.
Because I need the same buttons in many Activity screens I have extended Button to make a RachelButton and I set it up in the constructor.
CODE:...............
Then an example of the resource I am using to generate a colored button is this:
CODE:.............
As you can see in the code I am setting the text color and I'm sure that this color exists as a resource.
But setting the text color like this has no effect at all, the text color on the button seems to be a darker shade of the button's background color.
Are there api to support go to back Programmatically i.e same effect as the back button of the phone.

I've prepared custom component based on LinearLayout. Whole component is defined in XML. Currently to use it you have to write:
<com.xxx.android.components.TopMenu
android:layout_width="fill_parent"
android:layout_height="44dp" />
Is it possible to set width and height in the java constructor? So it would be possible to write just:
<com.xxx.android.components.TopMenu />
I've tried to modify and set LayoutParams, but it didn't work for me.
If you use an AbsoluteLayout (I know that it is deprecated, but it was the only way to solve my problem ) you can give the childViews the tag "android:layout_x" and "android:layout_y" to set their absolute position within the AbsoluteLayout.
However I dont want to set these informationen in the xml, because I only know them at runtime. So how can I set these parameters at runtime programmatically? I dont see any method on the View like view.setLayoutX(int x) or something.

View 2 Replies View RelatedI know my original post (at http://groups.google.com/group/android-developers/browse_thread/threa..., I could not find a way to perform a reply, maybe it's too old) is not sexy, but I'm now facing that problem in many situations. Let me please rephrase what I attempt to do, and what my problem is.
I have a RelativeLayout made of three widgets (named 1, 2 and 3 on the illustrations below): one attached to its parent left border (labelled 1), one to its parent right border (labelled 2) and the third (labelled 3) inserted between the 2 previous ones (its left border is attached to the first widget right border, and its right border is attached to the second widget left border). The third widget (the middle/central one laballed "3") is far taller than the two others, and I would like the first and second items (1 and 2) to be vertically centered with the middle widget.
I have resorted to the "android:layout_centerVertical" attribute for both the first and second widget, but I do not get the expected result. See at the bottom the various layouts I'm mentionning. Could someone please help me, and tell me whether what I intend to do is feasible, and how? Thank you for your time.
