In HVGA emulator it'is worded fine. but in another emulator it is not. As you can see I put height=365dp,(I have to change height but I don't know how, 365dp works only in HVGA mode) what should I do here so it work for all emulator. I tried wrap_content and fill_parrent but when I set this paramteters the buttons gone (which are in another layout). I also tried this way android:layout_weight="1" android:layout_height="0dp". but no result here. Could you give me another solution

Better have parent layout as relative.
there you can put buttons always at bottom- by setting android:layout_alignParentBottom="true" in your property of button [or buttons manager in case there are more than one buttons]...
For the remaining screen you may have to use LinearLayout there, use it as an immidiate child and arrange your original view there.... make it android:layout_alignParentTop="true" and put your buttons view below it... by adding this android:layout_below= to button view.. this will make your linear layout to acquire all remaining space that has not taken by buttons.... add scroll view as immediate child of linear layout in case of smaller screens...
and you have least worries about multiple screens....
Enjoy

EditText and textView will not fit within layout bounds

I'm building a gridView which replicates the basic functionality of a Launcher (it allows you to create new folders - and arrange them within the gridView).
My problem is I have a textView and an imageView (which should appear below the bottom most tile [it is either white or grey depending on how many times the add image button is clicked] in the screenshot below) however they are being pushed outside the bounds of the layout for some reason - and I'm having trouble identifying which one is causing this to occur.
I've tried many different combinations of height and width paramaters as well as trying Linear vs Relative layout for my innermost child layout - but I still can't seem to keep the textView and an imageView from being pushed outside the layout completely and I'm having a bit of trouble nailing down what exactly is causing it.

Your FrameLayout is redundant as it only contains a LinearLayout, but more importantly it's set to 80dp height. This means that anything beyond 80dp will not be visible. Try setting it to wrap_content.

button:gravity="right" is not working

i am desinging a xml
<?xml version="1.0" encoding="utf-8"?>
<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="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="0.05"

<Button

android:layout_width="82dp"
android:layout_height="wrap_content"
android:gravity="right"
android:background="#3399FF"
android:text="Add" />
</LinearLayout>
</LinearLayout>
for button "Add" android:gravity=right is not working.i have give a layout:margin,then only its moving right.can anyone help me out.
It's a little unclear what you want, but do notice the following:
gravity affects the contents of the widget i.e. your button text.
layout_gravity affects positioning of the widget in the parent layout
So if you want the button to be on right, change gravity to layout_gravity.
Use RelativeLayout instead of LinearLayout.
and use android:layout_alignParentRight="true" for btnadd.
EDIT :
Code :
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="0.05"
android:background="#000000"
android:orientation="horizontal" >
<Button
android:id="#+id/btncancel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left|center"
android:background="#CCCCCC"
android:text="Cancel" />
<Button
android:id="#+id/btnadd"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_gravity="right"
android:background="#3399FF"
android:text="Add" />
</RelativeLayout>
Change the LinearLayout to be as RelativeLayout
and instead of android:gravity="right" use android:layout_alignParentRight="true"
It is because you use LinearLayout (orientation horizontal)
Try to use relative layout
you are using linear layout in linear layout your layout depends on orientation like you are using vertical:
use relative layout instead to solve your problem,and give margins you want
also to align your button right use:
android:layout_alignParentRight="true"
your problem would definetly be solved with this.
it was because of you are using android:orientation="horizontal"in Linear Layout
use this android:orientation="vertical"
or use this i modified your code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<RelativeLayout
android:id="#+id/RelativeLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="0.05"
android:background="#000000"
android:orientation="horizontal" >
<Button
android:id="#+id/btncancel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:background="#CCCCCC"
android:text="Cancel" />
<Button
android:id="#+id/btnadd"
android:layout_width="82dp"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:background="#3399FF"
android:text="Add" />
</RelativeLayout>
If you want to achieve something like this:
You can do that either with RelativeLayout or LinearLayout.
For LinearLayout you explicitely add space between the buttons. This is because the android:layout_gravitypositions the view only within the space, that LinearLayout has given. And this space is not the LinearLayout itself, but the sum of all views, that were layed out linearly (as the name says).
Here's my way of putting the two buttons:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >
<Button
android:id="#+id/btnadd"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Add" />
<ImageView
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight="1"
android:src="#android:color/transparent" />
<Button
android:id="#+id/btncancel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Cancel" />
</LinearLayout>
I always prefer LinearLayout over RelativeLayout as I experienced LinearLayout as more robust, especially on Android's 2.x versions.
BTW: The difference between android:layout_gravity and android:gravity:
The layout_gravity tells the parent layout of a view to position the whole view within the bounds that the layout defines. In case of LinearLayout this is the space that was allocated by linearly putting the views one after the other.
The gravity tells the view to position its foreground within the available space. You might have seen, that your Add-Button has shown the text on the right side.

Problems with LinearLayout, views aren't resembling the preview in Graphical Layout on device

So I'm having a problem that is driving me crazy. Knowing the purpose of my app isn't important/relevant so I'll just paste my code from the xml file. The layout is a RelativeLayout, but the problem I'm having is inside of this LinearLayout.
Code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#drawable/background_orange"
android:id="#+id/rel_layout" >
<RelativeLayout
android:id="#+id/layout_1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentTop="false"
android:layout_centerHorizontal="true">
<ImageView
android:id="#+id/component_1"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
android:src="#drawable/source1"
/>
<ImageView
android:id="#+id/component_2"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:layout_above="#id/component_1"
android:src="#drawable/source2"
android:layout_alignRight="#id/component_1"
android:layout_marginRight="-50dip"
android:layout_marginBottom="-25dip"
/>
</RelativeLayout>
<LinearLayout
android:id="#+id/problemIsHere"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:orientation="horizontal"
>
<EditText
android:id="#+id/edit_text"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight="1"
android:hint="What&apos;s your question?"
android:imeOptions="actionDone"
android:inputType="textCapSentences|textAutoComplete"
android:textSize="25sp"
android:layout_gravity="left"
android:textStyle="bold" />
<ImageButton
android:id="#+id/image_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="5dip"
android:layout_weight="0"
android:layout_gravity="right"
android:background="#drawable/source3"
/>
</LinearLayout>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_below="#id/problemIsHere"
android:gravity="center"
>
<ImageView
android:id="#+id/image_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/source4"
android:onClick="computeUserInput" />
<ImageButton
android:id="#+id/image_button0"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/image_view"
android:layout_alignTop="#id/image_view"
android:layout_marginLeft="-2dip"
android:background="#drawable/voice_recognition_touse"
/>
</RelativeLayout>
Again, this is nested inside of the parent, RelativeLayout. In the preview, when clicking on the "Graphical Layout" tab, this looks like exactly what I want; EditText to the left of a small ImageButton, with correct proportions and margins. However, when I run this on my device, the LinearLayout is REVERSED, meaning now that the EditText is to the RIGHT of the ImageButton. The proportions and margins are still accurate though. Does anyone know what is going wrong here?
Note: I've already cleaned and refreshed my project; this was ineffective. I've also tried removing the layout_gravity attributes, and that did nothing.
Thanks

Android floating buttons over a view

I was trying to have a floating button on my view, I googled and found this link which pretty well sums it up.
http://www.jondev.net/articles/Floating_Views_in_Android_(Buttons)
While this is true for one button, but what if i want to have two floating buttons one at "top left" and another at "bottom right".
I thought of having a relative layout which has two buttons with lay out gravities different. Will this work. I tried it and miserably failed. Has any one else tried to do this? Is there any way of doing this, if so please let me know.
You can achive that with a RelativeLayout:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ListView
android:id="#+id/listView1"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</ListView>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_marginBottom="15dp"
android:layout_marginRight="15dp"
android:text="Button" />
</RelativeLayout>
Note that the last added Widget is on top.
You can do it with RelativeLayout although you can also achieve that using FrameLayout (like in the example in your the link).
In FrameLayoutSet a proper gravity to the the buttons (Gravity.BOTTOM|Gravity.RIGHT, or via XML...), and in RelativeLayout set the reuiqred rules to the Buttons:
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
etc.
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ListView
android:id="#+id/listView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</ListView>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_marginTop="15dp"
android:layout_marginLeft="15dp"
android:text="Button" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_marginBottom="15dp"
android:layout_marginRight="15dp"
android:text="Button" />
</RelativeLayout>

How to place a button at a position little above the bottom in android

I need to place a button at the bottom of screen, leaving some space below it.
In other words I am using these two attributes for my button -
android:layout_alignParentBottom="true"
android:layout_marginBottom="20dp"
but the margin attribute wont work when I use alignParentBottom and the button sticks at the bottom only. Please tell me how to place it a little above the bottom .
Here's the xml
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:background="#drawable/board"
android:layout_marginLeft="10dp"
android:layout_marginRight="60dp"
android:layout_marginTop="15dp"
android:layout_marginBottom="10dp">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:text="Type of Lesion"
android:textColor="#8B0A50"
android:layout_marginTop="40dp"
android:id="#+id/disease_listheader_textview"
android:drawableBottom="#drawable/underline"/>
<ListView
android:id="#+id/disease_listview"
android:layout_below="#id/disease_listheader_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:divider="#drawable/divider"
android:layout_marginLeft="40dp"
android:layout_marginBottom="50dp"
android:cacheColorHint="#00000000"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/disease_search_button"
android:layout_centerHorizontal="true"
android:background="#drawable/disease_search_btn"
android:layout_alignParentBottom="true"
android:layout_marginBottom="20dp"/>
</RelativeLayout>
just make change in relative layout height attribute value to fillparent like
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
.................../>
hope this help you
Can you try this?
Replace the Button tag with the one mentioned below. I am trying to wrap the button in another dummy layout
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
android:paddingBottom="20dp">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/disease_search_button"
android:background="#drawable/disease_search_btn"
android:layout_marginBottom="20dp"/>
</LinearLayout>
This runs just the way you wanted
<RelativeLayout android:id="#+id/relativeLayout1" android:layout_width="match_parent" android:layout_height="fill_parent">
<Button android:text="Button" android:id="#+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_marginBottom="20dip"></Button>
</RelativeLayout>
