I am developing for android. The app is designed in XML in Linear Layout. What I want to do is to leave some blank lines between the consecutive buttons/text to ensure some neatness in the GUI. Is it posible to do it in Linear Layout? Please help...
You should use margins to seperate different components in your layout. An example of how this would look in your XML is: android:layout_marginTop="12dp"
If you want to leave space outside the border of text/button and next view elements you can use android:layout_marginLeft, android:layout_marginRight, android:layout_marginTop and android:layout_marginBottom.
If you want to leave space between border of the text/button and actual content of the text/button you can use android:paddingLeft, android:paddingRight, android:paddingTop and android:paddingBottom.

I am working on an android app and I have a scrollview, and in that, I have a linear layout in the main activity. I want to have the top and bottom borders of the linear layout to be "faded
" so as the user scrolls down the child views in the layout will "fade out" as the go down.
Here is an example of what I am trying to achieve in my linearlayout or scrollview (the "fading bottom border".
Thanks for you help!

You can do that by using the following attributes in the ScrollView.
android:requiresFadingEdge="vertical"
android:fadingEdgeLength="20dp"
If you want it on devices before API14, you need to use the following:
android:requiresFadingEdge="vertical"
android:fadingEdgeLength="20dp"
NOTE: This is actually discouraged as it is seen to have a negative performance impact on devices.
At the bottom of your layout, you can have a view above the listView, and set Gradient Color for the view, and also make it semitransparent, then you can have the effect you want.
Hello i have an Relative Layout in Android, with EditTexts, TextViews, one Spinner and RadioButtons. It's a lot of things for only one screen, so i need to change for a ScrolView. When i try add the line in the first line and on the last Row, I have problems.
How can i add a scroll on my screen without lose all the layout I built so far?
so i need to change for a ScrolView
You do not need to change "for a ScrolView". You need to wrap your RelativeLayout in a ScrollView.
How can i add a scroll on my screen without lose all the layout I built so far?
Put a ScrollView around your RelativeLayout:
<ScrollView>
<RelativeLayout>
<!-- existing stuff here -->
</RelativeLayout>
</ScrollView>
As #CommonsWare has said, you can just wrap your current layout with a ScrollView.
Just keep in mind that a ScrollView must have only one child.
I've created a custom dialog builder that contains 2 buttons.
Depending on the dialog's setup, I may choose to hide one of the buttons completely, using Window.GONE.
Ideally what I want to happen is:
1. If there is only one button, then fill the layout with it
2. If there are two buttons, then split up the space in the layout equally with these
Is it possible to do this without having to work out the width of the dialog, the number of buttons and then set the sizes manually?
I was hoping there may be a neater way to perform this
ok, here is how I would do it:
<LinearLayout layout_width:fill_parent layout_height:wrap_content>
<Button
layout_width=fill_parent
layout_height=wrap_content
layout_weight=1/>
<Button
layout_width=fill_parent
layout_height=wrap_content
layout_weight=1/>
</LinearLayout>
The trick is to put both elements a width of fill_parent and a weight of 1. If they are both drawn, they will each take up half the screen. If you use View.Gone, one of them will disappear and the other should take up all the space.
yes of cource put your views means button in linear layout and give yor buttons equal layout_weight will solve your problem.
Hello i have used a Relativelayout in android using XML but when i see image in graphical layout there is small margin left at bottom in different screensizes.How to remove that margin.I also used a ScrollView in layout.
I think you have to set bottom margin in negative
like
android:layout_marginBottom="-10dip"
Check whether you have used padding for your layout,
Better post your layout file and/or screenshot.
Take a look at my layout

My problem is that the textviews (named header1 to 5) are resizing its containers when a certain amount of letters are written into it, although there is still some space left.
What changes do I have to make that the layout stays in its original state independent from the amount of text located in the headers?
This might be because of this attribute.
android:inputType="textMultiLine"
If you want your textview to have only one line you can use android:singleline="true"
Add the attribute
android:maxLength="2"
to the textview. This way you can limit the number of characters.
I think its better to use Relative layout instead Linear layout in the XML so that objects in Relative layout are easy to manage dynamically, all you need to do is that put all those text views in the Relative layout and set these parameters:
layout align left:
layout align right:
And other solution which is not appropriate is that fix the size of text view then it will not expand.
And please see the Documentation for further details of Relative Layout.
Set the width and heigth of your textview to a fixed amount of dp. This will prevent the textview from streching beyond the width and height you declared. Like this:
android:layout_width="50dp"
android:layout_heigth="50dp"
For me the solution was to use
android:layout_width="0dp"
together with
android:maxLines="1"
