I have a image view and grid view in my .xml file. When I am executing this file its getting some space between grid view and image view. How to avoid this space...can any one help me to solve this problem.
thanks in advance...
my xml code is:
android:layout_width="0px"
android:layout_height="0px">
</Button>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/prevMonth"
android:src="#drawable/cal_left_arrow_off2"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</ImageView>
<Button
android:id="#+id/currentMonth"
android:layout_weight="0.6"
android:textAppearance="?android:attr/textAppearanceMedium"
android:background="#drawable/calendar_bar2"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</Button>
<ImageView

android:src="#drawable/blue_bg_with_text2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
</ImageView>
</LinearLayout>
<GridView
android:id="#+id/calendar"
android:numColumns="7"
android:layout_gravity="top"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
</GridView>
You should try setting the android:gravity attribute correctly, and it has to work:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout android:gravity="bottom|center_horizontal"
android:layout_width="fill_parent" android:layout_height="wrap_content">
<ImageView android:id="#+id/calendarheader" android:src="#color/blue_start"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:minWidth="250dp" android:minHeight="30dp">
</ImageView>
</LinearLayout>
<GridView android:id="#+id/calendar" android:numColumns="7"
android:layout_gravity="top"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:background="#color/blue_start">
</GridView>
</LinearLayout>
i'm using here simple color background, and there is no gap:
If you still having the problem, then you should see your blue_bg_with_text2 image, whether it has any empty pixels at the bottom.
ps: ignore the android:minWidth="250dp" android:minHeight="30dp" part, it is there to imitate an image with that size.
Update
Here is the same view using RelativeLayout (it's a bit clearer at least for me):
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Button android:id="#+id/selectedDayMonthYear"
android:textColor="#000000" android:layout_gravity="center"
android:textAppearance="?android:attr/textAppearanceMedium"
android:layout_width="0px" android:layout_height="0px" />
<ImageView android:id="#+id/prevMonth" android:src="#drawable/cal_left_arrow_off2"
android:layout_width="wrap_content" android:layout_height="wrap_content" />
<ImageView android:id="#+id/nextMonth" android:src="#drawable/cal_right_arrow_off2"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_alignParentRight="true" />
<Button android:id="#+id/currentMonth" android:layout_weight="0.6"
android:textAppearance="?android:attr/textAppearanceMedium"
android:background="#drawable/calendar_bar2" android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/prevMonth"
android:layout_toLeftOf="#id/nextMonth"
android:layout_alignBottom="#id/prevMonth"
android:layout_alignTop="#id/prevMonth" />
<ImageView android:id="#+id/calendarheader" android:src="#drawable/calendarheader"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:minHeight="25dp"
android:layout_centerInParent="true"
android:layout_below="#id/currentMonth"
android:layout_margin="0dp"
android:scaleType="fitXY" />
<GridView android:id="#+id/calendar" android:numColumns="7"
android:layout_gravity="top" android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#id/calendarheader"
android:layout_margin="0dp"
android:background="#color/white_fader_end">
</GridView>
</RelativeLayout>
I've added to it my resources as background (two of them are actually screenshots from yours).
What i observed is, you must
either use a static image for your
calendar header background, or,
if you use an xml drawable, you have
to drop the stroke element from it / set its android:width to 0
otherwise it will add an unnecessary gap around your view's drawable, that is as wide as the stroke width you've specified.
my output using static images as backgrounds looks this way:
Update 2
The problem is not between your calendar header and gridView, but inside your gridView.
It has a 'padding' of 5 px inside (not real padding, see how it gets there):
The default selector for the GridView is a 9x9 patch rectangle with a border of 5px.
That 5 px is visible all around your gridView.
You can specify a different listSelector for this grid either by xml:
android:listSelector="#drawable/grid_selector"
or from code (onCreate):
gridView.setSelector(R.drawable.grid_selector);
Now if your grid_selector is an image or is a drawable xml without any margins, then the gap that causes the problem is gone.
You can also hide that gap, by setting a background color to your gridView, that matches or grandients the calendar header's background color.

I have a custom listView which is built from the following row item layout. What i need is for the background to be semi-transparent. I can do this as shown in the code below using the Alpha attribute and setting it to 0.5. However, what this also does is make my textView and imageView semi-transparent too.
How can i just make the background colour semi-trans, but have the text and image normal/opaque?
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:background="#ffffff"
android:padding="8dp"
android:alpha="0.5">
<ImageView
android:id="#+id/Image"
android:layout_width="110dp"
android:layout_height="90dp"
android:layout_marginRight="6dip"/>
<LinearLayout
android:id="#+id/Text"
android:orientation="vertical"
android:layout_width="0dip"
android:layout_weight="1"
android:layout_height="fill_parent">
<TextView
android:id="#+id/Text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="22dip"
android:textStyle="italic" />
<TextView
android:id="#+id/Text2"
android:layout_width="fill_parent"
android:layout_height="0dip"
android:layout_weight="1"
android:singleLine="true"
android:ellipsize="marquee"/>
</LinearLayout>
</LinearLayout>
Try using the ARGB value for the background instead of using alpha. You can set it to 50% transparency by using #80FFFFFF.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:background="#80ffffff"
android:padding="8dp">

I am developing an app which has a splash screen, you can see it in the picture below.
My problem is that I am needing to put a progress bar as you can see in the picture below without many layouts, because now I have eight layout in order to get this effect (layout-sw320dp, layout-sw320dp-land, layout-sw480dp, layout-sw480dp-land...600,720).
I was trying use relative layout and center horizontally the progress bar, but with different screen sizes the progress bar get other position vertically.
Could I solve it with less folders?
This is my layout file for 320dp:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/RelativeLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/splash_screen_land"
android:orientation="vertical" >
<ProgressBar
android:id="#+id/progressBar1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="24dp" />
</RelativeLayout>
I suggest you use just one layout file, let's say splash.xml. Put in a RelativeLayout your ImageView, with android:layout_centerInParent="true". Then your ProgressBar with android:below="#id/image" to put it relatively below the image. You can change the layout paddingBottom to adjust views in the center of the layout.
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingBottom="#dimen/padding_bottom">
<ImageView
android:id="#id/image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true" />
<ProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/image"
android:minHeight="#dimen/progress_height"
android:minWidth="#dimen/progress_height" />
</RelativeLayout>
Now instead of having many layouts, you will keep the above layout, and create many values according to your screen sizes. Meaning :
values/dimens.xml
values-large/dimens.xml
values-land/dimens.xml
etc.
Thus, your view's layout won't change from a screen to another, only their size will !
Maybe 3 horizontal LinearLayout using layout_weight to center everything horizontaly with respect of the ratio, containing a vertical LinearLayout with centered gravity?
If you post your actual layout file, that could be easier to explain.
Edit:
Something like that: (you may have to play with the layout_weight values to get the size you want:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"></LinearLayout>
<LinearLayout
android:orientation="vertical"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1"></LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:src="#drawable/splash_screen_land"/>
<ProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1"></LinearLayout>
</LinearLayout>
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"></LinearLayout>
</LinearLayout>
I could solve it with weightSum, layout_weight properties which are very useful to imitate percentages.
This is my code with the problem solved:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/LinearLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/splash_screen_land"
android:gravity="center_horizontal"
android:orientation="vertical" >
<android.support.v7.widget.Space
android:id="#+id/space1"
android:layout_weight="100"
android:layout_width="match_parent"
android:layout_height="0dp" />
<ProgressBar
android:id="#+id/progressBar1"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="15" />
<TextView
android:id="#+id/textView1"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="17"
android:gravity="center"
android:text="TextView"
android:textSize="20sp" />
</LinearLayout>
I hope this will be useful for someone else
I am trying to create a layout that would always display 2 images, splitting the screen length equally into half, leaving no whitespace on screen (even if the images are center cropped).
So far I have the following code, but this leaves a lot of empty white space at the bottom of the screen. The reason I use "RelativeLayout" within the "LinearLayout" is because I want my text1 view to come at the lower portion of my image 1 (overlapping the image1).
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="230dp"
android:layout_marginBottom="3dp" >
<ImageView
android:id="#+id/img1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"
android:contentDescription="#string/picture"
android:scaleType="centerCrop" />
<TextView
android:id="#+id/text1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:gravity="center"
android:padding="5dp"
android:textColor="#fff" />
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="230dp"
android:layout_marginBottom="3dp" >
<ImageView
android:id="#+id/img2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"
android:contentDescription="#string/picture"
android:scaleType="centerCrop" />
</RelativeLayout>
You are hardcoding the height to 230dp for each layout which could be causing the problem. In the Linear layout you should use weights to distribute the screen area equally.
Use android:layout_weight="1" in both the relative layouts
Check here for more information
Android: 2 relative layout divided in half screen
The layout you are describing is a simple, weighted LinearLayout. Simply add the following attribute to your LinearLayout:
android:weightSum="2"
Then for each RelativeLayout, change the height attribute to:
android:layout_height="0px"
And add the following attribute to the same RelativeLayouts:
android:layout_weight="1"
try to use the frame layout if you want to overlap the textview on image view and use layout weight on the frame layout
Sample code for layout xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<FrameLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_marginBottom="3dp"
android:layout_weight="0.5" >
<ImageView
android:id="#+id/img1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"
android:scaleType="centerCrop" />
<TextView
android:id="#+id/text1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Test"
android:gravity="center"
android:layout_gravity="center_vertical|bottom"
android:padding="5dp"
android:textColor="#android:color/black" />
</FrameLayout>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_marginBottom="3dp"
android:layout_weight="0.5" >
<ImageView
android:id="#+id/img2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"
android:scaleType="centerCrop" />
</FrameLayout>
I am solving a problem with image and text in one scroll view. The main problem is, that I get different image height from server side . But the place with image should be all the time same.
Now the height of image place is dynamic. The text should be scrollable with the image.
Is there any possibility how to make the image height static?
Thank you!

If you declare the ImageView with a fixed width and height it will remain static all the time.
Try something like:
<ImageView
android:id="#+id/imageView1"
android:layout_width="50dp"
android:layout_height="50dp"
/>
Put this ImageView inside a ScrollView and ofcourse put your TextView inside the same ScrollView.
you can use layout weights for your linearlayout. Set the width to 0 and let the weight determine actual size. Setting weight to 0.33 each gives each images 1/3 of the screen.
Or you could set one to 0.5 and the others to 0.25 each or whatever makes sense for your app.
Set the 3 images as:
<ImageView
android:id="#+id/article_image_back"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.33"
android:layout_gravity="center_vertical"
android:src="#drawable/sipka_l" />
I've got problem with my ListView item's background, it's bigger than should be.
Here is my background resource:
And it's screenshot from my device:

</LinearLayout>
Why the background is so big?
Since you dont want your image to scale to the dimensions of the list item, you should not put it as a background.
Instead you can do this. Let the background be white (since your car_bg resource is all white with one logo). Then, your listview layout can look like this:
<RelativeLayout> //background white
<ImageView> //Your car_bg with width and height set as wrap_content
<LinearLayout> //All the content that you previously had
</RelativeLayout>
This way your image will not get scaled and remain as the original one. That said, you must now take car of different screen dimensions yourself. You must have different densitiy images available for your car_bg resource.
Try scaling the ImageView to keep its aspect ratio instead of attempting to set its height/width manually. This is most likely why your ImageView appears to be stretched.
