I need to create a layout exactly like in the picture. What layout can I use? If I use LinearLayout, I can't add the icons in front of the text fields without using so many nested LinearLayouts. With RelativeLayout, I don't know how to make the Textfields start always on the same height. With the Grid layout, I don't know how to put two Textfields in one row, like for phone and area.
How do I create a layout similar to this one in Android:
I have tried using TableLayout but it didn't go as expected because the Rows take the width of the largest one.
You could try using horizontal linear layouts inside of a veritcal linear layout. Also, you could try creating a custom listitem and using a listview to create the rows you desire
I have to create Text Views and Edit Texts dynamically and insert it inside the linear layout(horizontal) which is already declared in the XML file. Number of Text Views and Edit Texts to be inserted varies dynamically. I am creating the views dynamically and adding it to the linear layout.But the problem is that if number of views is more it moves out of the screen in spite of coming in the next line.what should I do to make the views come in next line if no space is available.
There is currently no Android layout with that behaviour.
Nevertheless, it has already been tackled in other threads (such as Android - LinearLayout Horizontal with wrapping children), which provide guidance on how to implement such a layout.
You can't do it with linearlayout, try tablelayout!
Use ScrollView and add your LinearLayout into ScrollView.
What is the difference between linear and relative layout?
LINEAR LAYOUT ::
In a linear layout, like the name suggests, all the elements are
displayed in a linear fashion
Either Horizontally or Vertically and this behavior is set in
android:orientation which is an attribute of the node
LinearLayout.
Linear layouts put every child, one after the other, in a line,
either horizontally or vertically.

RELATIVE LAYOUT::
In a relative layout every element arranges itself relative to other
elements or a parent element.
It is helpful while adding views one next to other etc
With a relative layout you can give each child a LayoutParam that
specifies exactly where is should go, relative to the parent or
relative to other children.
Views are layered on top of each other in relative layout

Optimization::Have a look at Optimizing Layout Hierarchies
The Fewer Views, the Better::
The number one goal for your layouts should be using the fewest number of Views possible. The fewer Views you have to work with, the faster your application will run. Excessive nesting of Views further slows down your application.
A RelativeLayout hierarchy will typically use fewer Views and have a flatter tree than a LinearLayout hierarchy. With LinearLayout, you must create a new LinearLayout every time you want to change the orientation of your views – creating additional Views and a more nested hierarchy. As a result, it is recommended that you first use RelativeLayout for any layout that has any complexity. There is a high probability you will reduce the number of Views – and the depth of your View tree – by doing so.
Linear layouts put every child, one after the other, in a line, either horizontally or vertically. With a relative layout you can give each child a LayoutParam that specifies exactly where is should go, relative to the parent or relative to other children.
From Android developer documentation: Common Layout Objects
LinearLayout
LinearLayout aligns all children in a single direction — vertically or horizontally, depending on how you define the orientation attribute.
RelativeLayout
RelativeLayout lets child views specify their position relative to the parent view or to each other (specified by ID)
difference is simple: in LinearLayout we arrange stuff in linear manner (one after another), and in RelativeLayout we can place stuff anywhere on screen.
=> Linear Layout is arranged as a list.
Rest they are similar in functionality.
One of the characteristic feature of LinearLayout in Android is use of a property called Weight, which app can specify using android:layout_weight.
This attribute assigns an "importance" value to a view in terms of how much space it should occupy on the screen.
On the other hand, RelativeLayout do not support weight or in other words, RelativeLayout does not pay attention to android:layout_weight. That's a property of LinearLayout.LayoutParams, but not of RelativeLayout.LayoutParams.
Linear Layouts
Linear Layouts are great for aligning views in rows and columns.
They are a good way to divide up one place using layout weights that will expand or shrink views depending on the size of the Display.
Relative Layouts
Relative Layouts are great for positioning elements relative to one another.
For example putting B below A or putting C in the lower left hand corner.Check the Screen shoot
Relative layout also make it easy to overlap views. For Example : view A is overlapping view B. Check the Screen-Shoot
RelativeLayout is more flexible than LinearLayout but if you have proper knowledge about LinearLayout you Can use that too.
For LinearLayout every attribute has a significant position hardcoded by the developer.
For RelativeLayout you can change the position by relating with others attribute.
The following link should explain visually how the layouts work "Visually"

Add some components to the window and mess with layouts to see what happens this is how I learned what each one does.
In the relative layout ,all the content in the layout page is related to other contents in the example_layout.xml page
In the case of Linear Layout the elements are displayed in the linear format
The difference between linear and relative layout in android is that in linear layout, the "children" can be placed either horizontally or vertically, but, in relative layout, the children can be placed with relative distance from each other. This is the difference between linear and relative layouts.
I am trying to build a layout dynamically which display some text and image for the most part, but has a series of buttons placed next to each other in the bottom.
I have a linear layout that carries the text, another linear layout that carries the image. And yet another linear layout that carries the buttons that get created in a for loop. I have a main layout aligned vertical that adds the text, image and buttons layout, in that order. To finally generate something like this:
Text ....
Image ...
Button1 Button2 Button3....
The problem is the number of buttons get decided at runtime, so if there are more than 4 buttons, the 5th button gets displayed really tiny. Also, when I tilt the phone, I get only the text and image showing, but no buttons coz the image covers the entire screen.
Layoutting seems to be pretty complicated to me, any help is appreciated!
Thanks

You do not need to wrap single views in a linear layout, so add the text and image directly to the root linear layout. You might consider using a relative layout instead of linear for the root.
Using FILL_PARENT and WRAP_CONTENT for the LayoutParams width or height can give some useful results. For example, using FILL_PARENT for the image height might scale it down to leave room for the buttons.
Be careful with LayoutParams because there are lots of them and only the one that matches the ViewGroup class should be used.
One option would be to implement an onLayout method of your own in a custom ViewGroup. You will be passed the dimensions you have to work with and be able to position all the views as you see fit.
