I have this layout for my header:
<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/home"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Home"
android:background="#drawable/ic_menu"
android:textSize="11dp"
/>
<Button android:id="#+id/questions"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Questions"
android:textSize="11dp"
android:background="#drawable/ic_menu"
android:layout_toRightOf="#+id/home" />
<Button android:id="#+id/businesses"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="11dp"
android:text="Businesses"
android:background="#drawable/ic_menu"
android:layout_toRightOf="#+id/questions"
/>
<Button android:id="#+id/learn"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Learn"
android:textSize="11dp"
android:background="#drawable/ic_menu"
android:layout_toRightOf="#+id/businesses"
/>
</LinearLayout>
What I thought was that if I made the button backgrounds with images, then that would enable me to not have space between the buttons. Right now, the header buttons render nicely, but there is a thick whitespace background space between them. How could I get rid of that white space and make the space between them just 1px?
I just uploaded a photo of the emulator. See the 4 dark boxes on the top of the screen? That is the header with the spaces.
Thanks!
There is a potential solution in a similar question here, Is there a way to completely eliminate padding in a LinearLayout containing buttons?
Your drawable ic_menu could have padding, if you are using a 9-patch for that image, when you author it make sure the black lines along the right and bottom are as you intended, because this is for specifying the content area in your 9-patch and could contribute to padding.
Also, try adding 0dp for both margin and padding on the buttons.
Hope that helps.
The problem is that the image contains a border color. Remove the border from the image, or use a solid color #868686, which is the image center color.

I'm trying to build the following layout on Android without any success.
I want a text to be displayed on my screen. It can take the whole width, but must be centered horizontally.
On the same line, on the right side of the screen I want to display a small layout. It shouldn't impact the horizontal centering of the main text and the main text shouldn't be visible behind the layout displayed on the right.
I cannot use a hard color for my layout background as it's displayed on a transparent background over a bitmap...
Any idea on how to achieve this ?
I can either use a RelativeLayout in which case the main text isn't centered based on the middle of the screen (it takes the right layout width into account)
Or the text is displayed behind the right layout...
Edit:
Here is one of my test
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:orientation="horizontal" >
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="bottom|center_horizontal"
android:layout_centerInParent="true"
android:fontFamily="sans-serif"
android:layout_marginLeft="2dp"
android:layout_marginRight="2dp"
android:singleLine="true"
android:textColor="?android:attr/textColorPrimary"
android:textSize="17sp"
android:text="very looooooooooooooooooooooooooooooooong text"
android:textStyle="bold" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_centerInParent="true"
android:layout_alignParentRight="true"
android:padding="3dp"
android:visibility="visible" >
<ImageView
android:layout_width="24dp"
android:layout_height="24dp"
android:layout_gravity="center_vertical"
android:filter="true"
android:src="#drawable/device_access_time" />
<Spinner
android:layout_width="20dp"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical" />
</LinearLayout>
</RelativeLayout>
RelativeLayouts adhere to the principle of z-indexes, so if you put the right-aligned layout first, the centered text view will be drawn correctly on top.
How can I place drawableLeft and button text of AppCompatButton like in the image below?
I have tried to apply paddingLeft, but the text is moving away from the drawable to the right.
<android.support.v7.widget.AppCompatButton
android:id="#+id/filterBy"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:drawableLeft="#drawable/ic_btn_filter"
android:paddingLeft="20dp"
android:text="#string/filter_by"
android:textAllCaps="false" />
And so far the result is looking like
Layout
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/profileHeader"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:layout_marginTop="10dp">
<android.support.v7.widget.AppCompatButton
android:id="#+id/findFriends"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:drawableLeft="#drawable/ic_btn_search"
android:text="#string/find_friends"
android:textAllCaps="false" />
<android.support.v7.widget.AppCompatButton
android:id="#+id/filterBy"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:drawableLeft="#drawable/ic_btn_filter"
android:text="#string/filter_by"
android:textAllCaps="false" />
</LinearLayout>
And the interpreted requirement for making things clear.
Using layout_weight property am adjusting the width of both buttons and what i have to do is, the text should be in center of the button
and the drawable should be aligned near left of the text.
Any suggestion please?
use
android:drawablePadding=""
probably you can't, if you want like this then you have to make it using complex layout like this see
I have 8 buttons inside a LinearLayout and I don't want any space betwen them. I have tried set all padding and margins to 0 and nothing.
Any solutions?
You could use negative margins but could be bad practice. Most 9-patch PNGs have transparent areas around the visible ones, that could be why it looks like you have margins. Try turning-on Show layout boundaries to investigate. It's under Settings > Developer Options.
Try this code. Use layout_weight=1 while, layout_width="0dp".
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:padding="3dp"
android:background="#color/green">
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:background="#color/green"
android:text="Submit"
android:textColor="#color/white"
android:layout_weight="1"
android:id="#+id/submitQuestionnaireButton"/>
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:background="#color/white"
android:text="Cancel"
android:textColor="#color/green"
android:layout_weight="1"
android:id="#+id/cancelQuestionnaireButton"/>
</LinearLayout>
I wanted to make two equally-sized radio buttons with a custom background, text, and an image to the right of the text. Because of how different these are from a standard "Button", I made them using a clickable "RelativeLayout".
The text and the image are of different heights, but I want each one to be centered vertically in the button. I also want the combination of the text+image to be centered horizontally in the button. This second part is what I'm having trouble with; it's off-center, close to the left side. In the image below, the left side is what I want, but the right side is what's happening. The image on one of the buttons (the one with the longer text) is resized to be smaller, too... Though there is still plenty of space on the right side of the button.
Here is my code:
<LinearLayout
android:baselineAligned="false"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<RelativeLayout
android:id="#+id/my_button"
android:background="#drawable/radio_button"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:gravity="center_horizontal">
<TextView
android:id="#+id/button_textview"
android:text="#string/button_label"
android:textAppearance="?android:attr/textAppearanceButton"
android:layout_centerVertical="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></TextView>
<ImageView
android:contentDescription="#string/image_description"
android:id="#+id/button_imageview"
android:layout_centerVertical="true"
android:src="#drawable/my_icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/button_textview">
</ImageView>
</RelativeLayout>
<RelativeLayout
... same thing for the second button ...
</RelativeLayout>
</LinearLayout>
What am I doing wrong?
Use this as your button:
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_gravity="center_horizontal"
>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:text="MyButton"/>
<ImageView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:src="#drawable/my_image"/>
</LinearLayout>
Now, you can place it in other parent views. To apply layout attributes to above button, place those attributes in the outer <LinearLayout> tag of above button.
Alternative:
You can set custom images to be drawn on sides(Left,Right,Top,Bottom) of a TextView using attributes like:
android:drawableLeft="#drawable/my_image"
Turns out the solution was adding
android:paddingRight="0dip"
strangely enough, even though I didn't put any padding there in the first place.
I have a linear layout with several buttons in it. The button images are all the same size and have the same attributes... except for one button. This one button has a smaller font size. All the buttons except for this one are in a perfect line exactly the way I want. For some reason, the button with the smaller font appears a little lower on the screen than the other buttons. I'm having a hard time wrapping my head around the idea of a button that requires less space taking up additional space.
Might someone give me a hint on what to read up on?

/>
</LinearLayout>
The one that's wonky is the 2nd from the bottom, with the different onclick event. The style has 11pt for the character size. If I use it (and a 1 letter button name, like the others) it behaves. But that's not what the ASR33 'enter' key has on it. So if I reduce the font size to say 6 pt, the weirdness happens.
The style can be seen here.
Again, just reading references or ideas please, I can figure it out if I have a word or two to search on. It's hard to know what you don't know...
RESOLUTION
Anurag has it right, see his answer below. Here's an excerpt of the updated LinearLayout:
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:baselineAligned="false">
maybe the re sizing has happened due to the wrap_content property of your button. so what you should do is have a fixed height to the linear layout holding all the buttons while its with is set to fill parents.
and inside the linear layout let individual buttons have height set to wrap content which will give all the buttons the same height as that of the linear layout and also set the attribute android:adjustViewBounds="true" for the small button. this attribute will resize your image button to maintain the aspect ratio. i hope this helps.
EDIT:
So here is the solution to your problem, something that was caused due to the base alignment property of the linear layout. A horizontal LinearLayout aligns the baselines of all its child controls by default. So the first line of text in your multi-line button is vertically aligned with the single line of text in the other buttons. set android:baselineAligned="false" on the LinearLayout. This worked perfectly on my HTC.
