I'm feeling difficult to implement , two widgets(say spinner) in linear layout one next to the other. I mean layout height of both spinner is wrap content, but width should be first half for the first spinner, second half of the screen to the second spinner. In linear layout they coming one down the other. I tried in Relative Layout, but as i gave width as wrap_content both are coming one next to each other but lot of space is remaining right to second spinner. I have seen in few apps this working out, but im not getting it.
Use layout_weight. This will force the two spinners to take up half of the space each.
<LinearLayout
android:orientation="horizontal"
... >
<Spinner
android:layout_height="wrap_content"
android:layout_width="0dp"
android:layout_weight="1"
... />
<Spinner
android:layout_height="wrap_content"
android:layout_width="0dp"
android:layout_weight="1"
... />
</LinearLayout>
I had the EXACT same problem one day. I've also tread a lot of different tricks to get it working. I ended putting both spinners in their own layout. Was weird but it worked.
relative layout is intended for putting views related to each other . it has nothing to do with their sizes.
for linearLayout , set the height/width (depending on orientation of the layout) of both views to 0px and the weight to 1 . this will make each take half the space.
<?xml version="1.0" encoding="utf-8"?>
<Spinner
android:id="#+id/spinner1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:entries="#array/testArray" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/background_light"
android:orientation="horizontal" >
<Spinner
android:id="#+id/spinner2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:entries="#array/testArray" />
<Spinner
android:id="#+id/spinner3"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1" />
</LinearLayout>
</LinearLayout>

I have a layout contain one image and 3 text field
I've tried to align the image to right and text field to left but I've failed
I've used
android:layout_gravity="right" for image and left to text but it did not work also I've used end and start in gravity with no success
this is the layout code:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">

Try to use a <RelativeLayout> instead of a <LinearLayout>
With the RelativeLayout you could place a widget depending on the position of another widget
Here the Relative Layout description
Hope this will help, I have not had time to test....
One linear layout should have vertical orientation and contain the 3 text fields.
One linear layout should have horizontal orientation and contain both the above linear layout and the image.
To push two views to the edges of the screen, you can also give each a left/right margin and then put a blank view with weight = 1 in between them.
Please read a bit more on how layouts work on Android and the different types available to you. A LinearLayout will stack the containing Views either Horizontally or Vertically one after the other. A FrameLayout is simply a container and the items within have to position themselves. RelativeLayout allow you to position your views with a relative reference to other views (in your case, you can position your ImageView, and then your 3 TextViews relative to where the ImageView is).
If you can use LinearLayout instead of RelativeLayout, you should do so, as RelativeLayout is always slower, due to having to perform two passes prior to rendering as it needs to measure each view and then also perform the layouts based on that. You might be looking for something like (pseudo-code):
<LinearLayout orientation=horizontal>
<LinearLayout orientation=vertical>
<TextView />
<TextView />
<TextView />
</LinearLayout>
<ImageView />
</LinearLayout>
You have not described your question well . Check below code if it works .
You just forgot to add orientation in linear layout containing one text view and a Image view .
Add Orientation to Your Linear Layout.
My app currently looks like this:
When I click on a button, the border color changes to green as shown above. I added a scrollview for my list of words as shown on the right side of the image. The problem is that this scrollview covers nearly the entire width of the screen and I am unable to click on the the first three rows of buttons.
A brief description of the layout:
I created a relative layout. The 25 buttons are in this relative layout. Then also within the relative layout I created a scrollable linear layout containing 20 textviews
Can someone please help me fix this layout? I want to be able to click on all the buttons and have the scrollview not block the buttons.
And I thought it might be a good idea to put the 25 buttons in its own relative layout within the main relative layout. Does anyone know how I can do that without redoing the entire layout?
Also, if you guys have any advice on the correct way to code the layout please let me know. I am fairly knew to android programming and don't know if I should use relative layout vs linear layout vs frame layout or match_parent vs fill_parent vs wrap_content. Please let me know if I am misusing any of them.

Use a LinearLayout instead of RelativeLayout as your top layout and make it android:orientation="horizontal".
Then put all of your buttons in a RelativeLayout with an android:layout_weight="1" and android:layout_width="0dp".
Also put the ScrollView in a second RelativeLayout with a width of "wrap_content".
Here is the structure:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<RelativeLayout
android:layout_widtht="0dp"
android:layout_heigh="fill_parent"
android:layout_weight="1">
All buttons go here...
</RelativeLayout>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="fill_parent">
Scroll view goes here...
</RelativeLayout>
</LinearLayout>
I have an Android application that goes about like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent"

android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.90" >

android:layout_width="70dip"

android:layout_height="wrap_content"
android:layout_alignParentLeft="true"

android:layout_below="#+id/button_1_of_10"/>
<!--Another 8 buttons-->
<RelativeLayout

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"

I need the 10 buttons to fill up the entire height from the top to the footer (the 0.1 weighted RelativeLayout), while all the buttons keep an equal height. However, I want to know whether there is a kind of equivalent to the layout_weight from LinearLayout, but for RelativeLayouts, as it's not performant to have nested weights in LinearLayouts. I'm not really looking for other solutions, because I still have some thing to try, but I want to know whether or not this is possible?
My question, just to be clear, is: Is it possible to have an amount of Buttons with an equal height in a RelativeLayout and at the same time fill up all the available space?
To use weight you need to use a LinearLayout, just make a linear layout with the buttons take the space you want and then on each button inside have android:layout_height="0dp" and also a android:layout_weight="1"
You don't need to sum all the weights to 1, just think of items with the same weight have the same size
I'm confused and frustrated that I can't get my EditText field to take up a rational amount of space in the layout without explicitly telling it how many pixels to be.
I'm *sure I'm missing something obvious, but my experience is that EditText totally ignores layout_weight and either grows/shrinks dynamically with the text that is entered into it if I give it a layout_weight of "wrap_content" or takes up most of the space in its parent layout if I give it a weight of fill_parent.
So... what is the correct path to having an EditText field that occupies some portion of its parent layout (in my case Linear, but I'm flexible) so that it can have a label next to it and look like:
Name: [ EDIT TEXT HERE ]
Phone:[ EDIT TEXT HERE ]
etc.
TIA
You can do a couple different things. As mentioned, you should be using dp instead of pixels for layout. Using dp allows your views to scale by the screen's physical size rather than resolution.
Here's an example of specifying the edit boxes to appear to the right of each label and take up the remainder of a the screen:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="#+id/name_label"
android:layout_width="100dp"
android:layout_height="50dp"
android:text="Name:" />
<TextView
android:id="#+id/phone_label"
android:layout_width="100dp"
android:layout_height="50dp"
android:layout_below="#id/name_label"
android:text="Phone:" />
<EditText
android:id="#+id/name_text"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_toRightOf="#id/name_label" />
<EditText
android:id="#+id/phone_text"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_toRightOf="#id/phone_label"
android:layout_below="#id/name_text" />
</RelativeLayout>
Here's an example of a LinearLayout where weight is used:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="50dp"
android:orientation="horizontal">
<TextView
android:layout_width="0dp"
android:layout_height="match_parent"
android:text="Name:"
android:layout_weight="1"/>
<EditText
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="5"/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="50dp"
android:orientation="horizontal">
<TextView
android:layout_width="0dp"
android:layout_height="match_parent"
android:text="Phone:"
android:layout_weight="1"/>
<EditText
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="5"/>
</LinearLayout>
</LinearLayout>
Note that the LinearLayout has 7 views while the RelativeLayout accomplishes something similar with 5 views. LinearLayouts hare handy, but they're more complex. As your layouts get more complicated, they will perform worse than RelativeLayouts, especially when you nest them.
For each line use a horizontal LinearLayout.
Inside that, add a horizontal LinearLayout to 'wrap' the TextView. Give that LinearLayout a layout_weight of 20 (for example).
Use another horizontal LinearLayout to 'wrap' the EditText and set the EditText to fill_parent but give its outer LinearLayout a layout_weight of 80 (or whatever value based on 20+80 = 100% if you see what I mean).
EDIT: Also if you need to have multiple lines then to simplify the overall layout file, you can define a 'single line' layout file and use it as a custom layout entry.
//for your edittext set min width and max length
android:minWidth="40"
android:maxLength="30"
android:layout_width="wrap_content"
so that it will be always shows minimum width and your characters wont exceed more than 30.
You need to work with the Layout. LinearLayout is not the right Layout for your purposes. Have a look at TableLayout, which I think might fulfill your requirements. Have a look at the TableLayout tutorial.
I am working on the layout of the android app but i have found that all buttons are fixed in a column in Eclipse atuomatically. What should i do to make it to the desired position like the app shown in the link?? thanks

You could use RelativeLayout instead of LinearLayout in the main.xml file.
In this layout, you can place the components at any place in the layout, but the components are placed relatively to one another.
You can use a mixture of layout to make your view look sound. Also try using the Layout Orientation i.e. either Vertical or horizontal,
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
You could get 2 columns of buttons by having a vertical LinearLayout containing several horizontal LinearLayouts, each containing 2 buttons. Give the buttons equal weights to space them evenly, and some margin to make them look less cluttered.
E.g.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
xmlns:android="http://schemas.android.com/apk/res/android">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<Button
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="Button 1" />
<Button
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="Button 2" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="Button 3" />
<Button
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="Button 4" />
</LinearLayout>
</LinearLayout>
Or if the columns were going to be very long, you could use a horizontal linear layout containing 2 vertical linear layouts, and add the buttons to those.
Or you could use a TableLayout with 2 columns and have TableRows containing the buttons (I generally find table layouts harder to work with, perhaps that's just me).
I find it easier to write the xml in Eclipse rather than fiddling round with the graphical editor, then just switch over to the graphical editor every now and again to check it displays how you want. Look around online for a few example layouts and you'll soon get the idea.
To emulate that layout exactly, start with a RelativeLayout as mihail suggests, and use that to position your other layouts (such as your linear layout with buttons) and views.
