Android Buttons not stretching to width of the screen

I'm using a bootstrap library for android which can be found here. Ive imported the library into my application but the problem im having is that the buttons do not span the entire screen width.
I've tried placing the buttons side by side and using android:layout_weight="1" but the button just moves to the left and does not stretch. I've even tried using android:layout_width="match_parent" but that increases the buttons height as well.
this is what happens if i set android:layout_width="0dip" and android:layout_weight="1" (for ok/cancel) and android:layout_width="match_parent"(for check button)

You need to use width as 0dip instead of wrap_content if you use weight property.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="horizontal"
android:paddingBottom="15sp"
android:weightSum="2">
<com.beardedhen.androidbootstrap.BootstrapButton
android:id="#+id/OK"
style="#style/AppBaseTheme"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_margin="5dp"
android:text="OK"
bootstrapbutton:bb_icon_left="fa-envelope"
bootstrapbutton:bb_roundedCorners="true"
bootstrapbutton:bb_size="medium"
bootstrapbutton:bb_type="default"
android:layout_weight="1"/>
<com.beardedhen.androidbootstrap.BootstrapButton
android:id="#+id/cancel"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_margin="10dp"
android:text="CANCEL"
bootstrapbutton:bb_icon_left="fa-times"
bootstrapbutton:bb_roundedCorners="true"
bootstrapbutton:bb_size="medium"
bootstrapbutton:bb_type="default"
android:layout_weight="1"/>
And for single button, just use width as "match_parent"
<com.beardedhen.androidbootstrap.BootstrapButton
android:id="#+id/b_check"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_margin="10dp"
android:text="Check"
bootstrapbutton:bb_icon_left="fa-check"
bootstrapbutton:bb_roundedCorners="true"
bootstrapbutton:bb_size="medium"
bootstrapbutton:bb_type="default" />
Hope this helps.

How to make the height of the two ListView controls to fit UI?

The layout posted below creates the the UI. I currently get a result as shown in a.png and c.png (there is a lot of empty space), but I hope to achieve something similar to b.png and d.png. How can I do this?
I want the height of lvReceiver and lvOnlyOrExcept to increase and decrease automatically by the rows of data.

a.png
c.png

The xml which you are inflating for the list views must be having excess padding/margin. Please post the xml which you are using to inflate for both the list views. The issue lies there

Android - Emulator layout doesnt match with telephone

I have a layout problem.
There are 9 buttons on my layout from top to bottom.
When i run my android app on my 3.7 inc telephone, buttons seems good. But when i run on 3 inc telephone, last 2 buttons dont seem on display.
How can i fix my problem ?
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/arkaplan3"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".AnaEkran" >
<Button
android:id="#+id/btn1"
android:layout_width="160dp"
android:layout_height="48dp"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_marginTop="33dp"
android:text="Buton"
android:textSize="15sp" />

If you have 9 Buttons like you said you can:
- Resize all the Buttons so take them small
- Create other layout.xml like that you have for the different screen sizes.
Like this:
res/layout/your_file.xml
------------------------
res/layout-small/your_file.xml
------------------------
res/layout_big/your_file.xml
Also take a look a this http://developer.android.com/training/multiscreen/screensizes.html.
Hope I helped you.

You have to put up a graphic of what your trying to do or at least all your layout file.
If were trying to achieve a basic calculator layout simply nest LinearLayout's (DO NOT NEST MORE THAN ONCE, google expectedly said not to). Then just give all your buttons the same wighting attribute to make sure they are all the same size no matter the scene
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="fill_parent"

Complex layout with same layout_margin in Android

I have a problems with my layout_margin. I want to make my layout look like that:
(with "a" is margin)
My problems is, when i build my layout in other screen size, it look like that:
How can i make it beautiful with different screen size? This is my layout:
<LinearLayout
android:id="#+id/footer_result_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="vertical"
android:visibility="gone" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_gravity="center"
android:layout_weight="1"
android:gravity="center"
android:orientation="horizontal" >
<ImageView
android:id="#+id/btn_recommendtion"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:src="#drawable/coodinate" />
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_gravity="center"
android:layout_marginTop="20dip"
android:layout_weight="1"
android:gravity="center"
android:orientation="horizontal" >
<ImageView
android:id="#+id/btn_facebook"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_margin="5dip"
android:layout_weight="1"
android:adjustViewBounds="true"
android:src="#drawable/fb" />
<ImageView
android:id="#+id/btn_mixi"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_margin="5dip"
android:layout_weight="1"
android:adjustViewBounds="true"
android:src="#drawable/mixi" />
</LinearLayout>
</LinearLayout>

Try using a relative layout.
Here is an example using buttons. You can swap out the values of the buttons with your image views, and adjust your margins as needed. This should center the buttons, with the same margins on any screen.
<Button
android:id="#+id/btn_1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:text="BUTTON 1"
android:layout_centerHorizontal="true"/>
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_below="#+id/btn_1"
android:layout_centerHorizontal="true"
android:layout_marginTop="5dip"
android:orientation="horizontal" >
<Button
android:id="#+id/btn_2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:layout_margin="5dip"
android:text="BUTTON 2" />
<Button
android:id="#+id/btn_3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:layout_margin="5dip"
android:text="BUTTON 3" />
</LinearLayout>
It looks like this:

You'll need to use RelativeLayout for that.
Center button1 with android:layout_alignParentTop="true" and align it in the parent top with android:layout_centerHorizontal="true and work from there.

The code:-
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button 1"
android:layout_margin="10dip"
android:layout_centerHorizontal="true"
android:layout_alignParentTop="true"/>
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button 2"
android:layout_margin="10dip"
android:layout_alignParentLeft="true"
android:layout_below="#+id/button1"/>
<Button
android:id="#+id/button3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button 3"
android:layout_margin="10dip"
android:layout_alignParentRight="true"
android:layout_below="#+id/button1"/>
</RelativeLayout>
Considering the a=10

Children in Linear Layout with equal padding

I am currently designing a ButtonBar with 5 buttons (they will all be ImageButtons, but for now, only 3 of them are). This is my first android project so I'm learning as I go along. I'm trying to weight each button equally, without scaling them (have equal padding rather than equal width). This is my code so far:
<LinearLayout
android:id="#+id/back"
android:orientation="horizontal"
android:layout_height="50dip"
android:layout_width="fill_parent"
android:layout_alignParentBottom="true"
android:background="#000000"
style="#android:style/ButtonBar"
android:weightSum="5"
>
<ImageButton
android:id="#+id/info_button"
android:padding="20dp"
android:background="#drawable/info"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_weight="1"
/>
<Button
android:id="#+id/wishlist_button"
android:text="#string/wish_label"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_weight="1"
android:padding="20dp"
android:textSize="15dip"
android:textColor="#b7b7b7"></Button>
<Button
android:id="#+id/buy_button"
android:text="#string/buy_label"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_weight="1"
android:padding="20dp"
android:textSize="15dip"
android:textColor="#b7b7b7"/>
<ImageButton
android:id="#+id/dislike_button"
android:padding="20dp"
android:background="#drawable/dislike_button"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_weight="1"
/>
<ImageButton
android:id="#+id/like_button"
android:padding="20dp"
android:background="#drawable/like_button"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_weight="1"
/>
This is what it looks like now:
stretched weighted: http://i.imgur.com/MAfjp.png
This is what I want it to look like (closely):
non-stretched equally padded: http://i.imgur.com/vXTEy.png
Thank you for helping. I've been searching for the answer for a while and have tried so much already.

Here it is:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/back"
android:orientation="horizontal"
android:layout_height="50dip"
android:layout_width="fill_parent"
android:layout_alignParentBottom="true"
android:background="#000000"
style="#android:style/ButtonBar"
android:gravity="center"
>
<ImageButton
android:id="#+id/info_button"
android:background="#null"
android:src="#drawable/info"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_weight="1"
/>
<Button
android:id="#+id/wishlist_button"
android:text="#string/wish_label"
android:background="#null"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_weight="1"
android:textSize="15dip"
android:textColor="#b7b7b7"></Button>
<Button
android:id="#+id/buy_button"
android:text="#string/buy_label"
android:background="#null"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_weight="1"
android:textSize="15dip"
android:textColor="#b7b7b7"/>
<ImageButton
android:id="#+id/dislike_button"
android:background="#null"
android:src="#drawable/dislike_button"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_weight="1"
/>
<ImageButton
android:id="#+id/like_button"
android:background="#null"
android:src="#drawable/like_button"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_weight="1"
/>
</LinearLayout>
I don't know how style="#android:style/ButtonBar" is set, so if it doesn't show properly try remove it.

You could add a spacer element in between each of the images/buttons and assign the layout_weight to the spacer elements instead of the images/buttons. So it would look something like this:
<LinearLayout
android:id="#+id/back"
android:orientation="horizontal"
android:layout_height="50dip"
android:layout_width="fill_parent"
android:layout_alignParentBottom="true"
android:background="#000000"
style="#android:style/ButtonBar"
>
<ImageButton
android:id="#+id/info_button"
android:padding="20dp"
android:background="#drawable/info"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
/>
<LinearLayout
android:layout_height="wrap_content"
android:layout_weight="1" />
/>
<Button
android:id="#+id/wishlist_button"
android:text="#string/wish_label"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:padding="20dp"
android:textSize="15dip"
android:textColor="#b7b7b7"></Button>
<LinearLayout
android:layout_height="wrap_content"
android:layout_weight="1" />
<Button
android:id="#+id/buy_button"
android:text="#string/buy_label"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:padding="20dp"
android:textSize="15dip"
android:textColor="#b7b7b7"/>
<LinearLayout
android:layout_height="wrap_content"
android:layout_weight="1" />
<ImageButton
android:id="#+id/dislike_button"
android:padding="20dp"
android:background="#drawable/dislike_button"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
/>
<LinearLayout
android:layout_height="wrap_content"
android:layout_weight="1" />
<ImageButton
android:id="#+id/like_button"
android:padding="20dp"
android:background="#drawable/like_button"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
/>
</LinearLayout>
This may not be the most elegant solution since it adds several views to your layout, but it's worked for me in the past.

You should consider using only image button with equal size images with equal weight inside your LinearLayout.
