I'm obviously missing something fundamentally simple here. I have a LinearLayout containing 2 buttons. I've coloured the layout background red so I can see that it has expanded to fill its parent. I wanted the BooButton to center horizontally within the layout and the OtherButton to be right justified. But both buttons are on the left of the layout.

If I have 2 LinearLayouts split %50/%50 everything is fine. Weights are 1 and 1. As soon as I add a TextView inside the top LinearLayout, it stretches that layout. I use "wrap_content" as the documentation says I should when it comes to weights. As you can see the red and green should be split evenly and text on grey background should be inside red box.
Here is the code:..............
Now if I switch to "fill parent" as follows it actually works but it creates another problem. Here is the code (so far so good):
So looking at above we were forced to use "fill_parent" and we would think like we fixed the problem but here is the problem if we are using "fill_parent" (I took out the textview just to show the problem, textview doesnt make the problem go away anyways):
As you can see I assign the weights 3 (top red) and 2 (bottom green) but what actually happens is they get flipped: The red becomes 2 and bottom becomes 3. Just measure the pixels too see.
Here are the results of the 3 codes: http://imgur.com/iVt8g.jpg
I have a RelativeLayout that has two LinearLayouts in it. One is a bunch of TextViews and EditTexts that make up a form and the other is a ButtonBar that submits the form.
anyways, everything looks great in portrait, but when i switch to landscape mode the bottom TextView/EditText element is being hidden by the buttonbar.
screenshot to show the problem. as you can see some of the "email" textview and all of the email edit text are being hidden by button bar.

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.
In xml we have android:layout_gravity ... how can i set this for any view [say image button] ... from code ...
CODE:......................
The property android:layout_gravity="clip_vertical|horizontal" does the following as mentioned in the sdk documentation:
Additional option that can be set to have the top and/or bottom edges of the child clipped to its container's
bounds. The clip will be based on the vertical gravity: a top gravity will clip the bottom edge, a bottom gravity will clip the top edge, and neither will clip both edges.
But I can't see anything of this in my applications. so what is the purpose of this property exactly ?
I have 4 buttons in a horizontal linear layout. I'd like the right edge of the 4th button to align with the right edge of the linear layout (equal to screen width) I've tried using android:layout_gravity="right" but it doesn't work - the right button is to the right of the 3rd one but not right aligned . Am I missing something obvious?
main.xml with only the relevant layout params only is:
CODE:....
This doesn't seem to match the stated behaviour for layout_gravity in the SDK reference :"Defines how to place the view, both its x- and y-axis, within its parent view group."
I need to change it for an imageview that resides in a linearLayout changing it from top to bottom.

I would like to know if is there a way to call android:layout_gravity property from a java method. I didn't found any method in Android documentation to do it. This is the picture of the layout I want to implement: But in my situation, I need to do it through Java code, because I'll implement another layout views dinamically. To avoid merging xml layout with Java code, I would prefer make all layout using Java. Code...
View 2 Replies View RelatedI am not able to find out the perfect layout(viewgroup) to place four buttons as shown in the attached image. Basically, i want to place four buttons near the top/left/bottom/right edge of the screen. AbsoluteLayout helped, but it is deprecated (It is also better to avoid AbsoluteLayout as it is not very flexible for orientation changes)
View 2 Replies View RelatedI have touched on this question here, where Christopher gave an answer to this, but I dont really get it so I thought its time to make it a real question, not just a "follow up" =)
As it stands, the application Im writing has 4 different screens:
1. Screen 1 - list of nodes (main screen)
2. Screen 2 - options menu, tableLayout with buttons
3. Screen 3 - navigation
4. Screen 4 - text details on version etc
These screens can be navigated to/from using a "header" View that is placed on top. the header then has 4 different buttons:
+--------------------+
| menu with buttons |
+--------------------+
| |
| |
| |
| C O N T E N T |
| |
| |
| |
+--------------------+
The header is just an XML-file (header.xml) with a few buttons. That header.xml is the included in the Layouts using the include-markup. For example, the main.xml has the line:
<include layout="@layout/header"></include>
The header show up alright, but the question is - what is the correct approach to attach OnClickListeners for the buttons in the header?
Christopher pointed out that you could create an Activity class and do the hooks there, like this:
CODE:............
First, I cant make it work since the method setupHeaderButtons isnt accessible from FirstActivity.
Secondly, is this the right way to go at it?
When I'm clicking the linear layout it should be highlighted.

View 2 Replies View RelatedI'd like to get the height of a linearlayout. I found more information in this answer
View.getWidth()/View.getHeight() won't give you a meaningful answer until the view has been measured.
How will I know that view has been measured? Is there some event for it?
Solution for me is to get layout's height in overriden onWindowFocusChanged()
I'm trying to create a simple view of a header image, few buttons, then footer image. I'm using a LinearLayout inside a ScrollView.

I recently struggled with an apparently simple Android layout: I wanted a WebView above a Button. It worked fine with the following parameters:

Weight: unset
However if the web page became too big it spilled out over the button. I tried various combinations of weights and heights, and all except one either completely hide the button, or partially cover it...............

View 1 Replies View RelatedI want to add some checkboxes to a LinearLayout at runtime. The orientation is vertical and I want the checkboxes to appear at the bottom. I create each checkbox like this: CheckBox box = new CheckBox(this);
Then I add the box to the current view like this: addContentView( box , params ); What should be the params to get the effect I want? So far, everything I've tried ends up overlaying the new checkboxes on top of each other and on top of the other items in the layout. I want everything stacked in a column with the new checkboxes at the bottom.
