I have a Gridview which is on about the half of the screen. It is filled with ImageViews which are quadratic. The problem is that the GridView fills the complete width and so makes it scroll vertically.
I want to reduce the width of the GridView so much that it fits vertically without scrolling. I neither want the images to get deformed nor to change the column size.
I already tried different android:stretchMode's but with others than columnWidthit didn't showed the gridView at all.
Simply adding padding or margin is not what I want because it should fit on all screen sizes.
Here is my layout file:
<?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" >

Thanks in advance.
Ok, I found a pretty good workaraound which does exactly what I want. It's pretty simple:
since my GridView is quadratic, I managed to get the height of the LinearLayout and set the width of the GridView with that value. (I did not directly set the width on the GridView but on another LinearLayout I added to solve some import problems).
So here is my 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="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:gravity="center">
<LinearLayout
android:id="#+id/layout_help_p2"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center_horizontal"
android:orientation="vertical">
<GridView
android:id="#+id/gridViewPlayer2"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:numColumns="3"
android:gravity="center"
android:layout_gravity="center"
android:stretchMode="columnWidth"
android:horizontalSpacing="3dp"
android:verticalSpacing="3dp"
android:rotation="180" >
</GridView>
</LinearLayout>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<Chronometer
android:id="#+id/timer_p2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="20sp"
android:text="Chronometer"
android:gravity="right"
android:rotation="180" />
<Chronometer
android:id="#+id/timer_p1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="20sp"
android:gravity="right" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:gravity="center"
android:id="#+id/layout_grid_p1">
<LinearLayout
android:id="#+id/layout_help_p1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center_horizontal"
android:orientation="vertical">
<GridView
android:id="#+id/gridViewPlayer1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:numColumns="3"
android:gravity="center"
android:layout_gravity="center"
android:stretchMode="columnWidth"
android:horizontalSpacing="3dp"
android:verticalSpacing="3dp" >
</GridView>
</LinearLayout>
</LinearLayout>
</LinearLayout>
And here's how I managed the described process:
final LinearLayout mLayoutP1 = (LinearLayout) findViewById(R.id.layout_grid_p1);
final LinearLayout mLayoutHelpP1 = (LinearLayout) findViewById(R.id.layout_help_p1);
final LinearLayout mLayoutHelpP2 = (LinearLayout) findViewById(R.id.layout_help_p2);
mLayoutP1.post(new Runnable(){
#Override
public void run() {
layoutHeightP1 = mLayoutP1.getHeight();
mLayoutHelpP1.setLayoutParams(new LinearLayout.LayoutParams(layoutHeightP1, LinearLayout.LayoutParams.MATCH_PARENT));
mLayoutHelpP2.setLayoutParams(new LinearLayout.LayoutParams(layoutHeightP1, LinearLayout.LayoutParams.MATCH_PARENT));
}
});
So the result is: http://abload.de/img/4cu7w.jpg
This workaround only works because my GridViewis quadratic. If someone found a way to automatically reduce the width of a GridView/ListView that it fits vertically on the screen without scrolling, feel free to share it here!
I did not understand what exactly you are looking for. But you can set the width of the grid view and column width of the grid view dynamically.

I have a layout like below. Now, I don't want to set the width of relative layout to fixed 240 dp. I want to set the width of the relative layout to 1/3 the width of the screen. Is it possible to do that in the xml file. If it is impossible, how can I achieve that using java code ?
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/fullscreen"
style="#style/translucent">
<RelativeLayout
android:layout_width="240dp"
android:layout_height="fill_parent"
android:layout_gravity="right"
android:gravity="center"
android:background="#88000000"
android:id="#+id/sidebar">
</RelativeLayout>
</FrameLayout>
use weightsum="3" in the parent and layout_weight=1 in the child. Take a look a this reference
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/fullscreen"
style="#style/translucent"
android:orientation="horizontal"
android:weightSum="3">
<RelativeLayout
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_gravity="right"
android:gravity="center"
android:background="#88000000"
android:id="#+id/sidebar"
android:layout_weight="1"
>
</RelativeLayout>
<!-- other views, with a total layout_weight of 2 -->
</LinearLayout>
You have to use a LinearLayout to get the width of a view to be a third of its parentview.
Something like:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center"
android:background="#88000000">
</RelativeLayout>
<ViewGroup
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="2">
</ViewGroup>
</LinearLayout>
The key bit is the ratio of the layout_weights. The documentation is pretty good.
A LinearLayout with a android:layout_orientation="horizontal" is what you want, along with weights.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<RelativeLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
...all your stuff... />
<View
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="2" />
</LinearLayout>
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" />
Been struggling with this for a while now. I have a layout XML consisting of various LinearLayouts, with separate weighting. The end result looks like this..
Dont mind the colors, its just to see the break points..Anyway, below the Terminal/Origin etc LinearLayout is a ListView which is populated using a custom adapter. The data loads fine, but then the listView "breaks out" of the LinearLayout, and takes up most of the page
(Dont mind the colors, its just to see the break points..)
ie. it flows over the View above and below.

I may be missing something glaring, but for the life of me, I cant see it. Can anyone help?
Thanks a million..
This is because you have kept LinearLayout's height(the one wrapping listview) "wrap_content".Fixing its size to some dip would solve your problem.
Also make listview's height "fill_parent" then.
EDIT :
try this way:
...
<ListView
android:id="#+id/list_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
</ListView>
in upper two layouts,you user 0.2 and 0.4 as weight but in lower two layouts,you users 3 and 1...try it former way and see,if it can help you.also try making height of LinearLayout(the one wrapping listview) to 0dip.
Maybe it is late, but I could help someone.

Result:
Ok.. after consulting this post I came up with a fix
Remove the LinearLayout outside the ListView, its superfluous.
Add a height of '0px' (which I've found around the web) to the ListView ensures it obeys the android:weight parameter properly.
Hope this helps.
Remove the weight of id/filter.
Let the ListView have a weight of 1 with fill_parent height.
Remove the listView's immediate parent.
One other thing you missed, is to set the weightSum=sum_of all_child_weight in your root. That should fix the problem.
I'm trying to display some items in a GridView. I want each item to fill a relative part of the screen (image B) and all I have is GridView take just the space it needs at the top of the screen (image A). The image:
(I want each item sizes over 15-20% height of the main layout)
EDIT : I found this question Percentage width in a RelativeLayout. 'LadaRaider' gives a good answer but I don't know how to use that solution in my GridView cells. This is my layout.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/background">
<TextView
android:id="#+id/label_name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:gravity="center_horizontal"/>
<LinearLayout
android:id="#+id/ll_ok"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/lbl_choose"
android:textAppearance="?android:attr/textAppearanceMedium" />
<GridView
android:id="#+id/grid"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:numColumns="2"
android:columnWidth="100dp"
android:stretchMode="columnWidth"/>
</LinearLayout>
<LinearLayout
android:id="#+id/ll_wait"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/lbl_wait"
android:gravity="center"
android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>
</LinearLayout>
I have also created a custom layout to use in GridView items. It has just a TextView and a background.
I have GridView with 6 images in 2 columns. I want to display this 6 images in the middle of the screen. I set gravity properties to center but this center elements only horizontally. GridView takes whole screen.
<GridView
android:id="#+id/gridview"
android:layout_above="#id/ad" android:layout_alignParentTop="true"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:numColumns="2"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:stretchMode="columnWidth"
android:background="#ffffff"
android:gravity="center"
/>
Here is what I did to get the items in the gridview to center (notice the stretchmode, columnwidth, gravity and horizontal and vertical spacing):
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:padding="5dp" >
<GridView
android:id="#+id/gridview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:columnWidth="100dp"
android:gravity="center"
android:horizontalSpacing="10dp"
android:numColumns="3"
android:stretchMode="spacingWidthUniform"
android:verticalSpacing="10dp" />
</LinearLayout>
It took me a while to figure it out, but messing with those different values I was able to get them to center.
Try wrapping your GridView in a LinearLayout that has it's child elements centered and change your gridview's layout_height to "wrap_content". ex:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:gravity="center"
android:layout_gravity="center">
<GridView
android:id="#+id/homeGridView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:numColumns="3"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:stretchMode="columnWidth"
android:gravity="center" />
</LinearLayout>
Need to set the following attributes:
android:stretchMode="columnWidth"
...and...
android:gravity="center"
well, in case you are using a custom adapter thing to inflate single rowview inside your gridview then try to add android:gravity="center" to the layout of your single_row.. this will do the trick hopefully :)
i.e,
<?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:gravity="center"
android:orientation="vertical" >
<ImageView
android:id="#+id/ivClrBlock"
android:layout_width="88dp"
android:layout_height="88dp"
android:layout_marginBottom="5dp"
android:layout_marginTop="5dp"
/>
<TextView
android:id="#+id/tvClrName"
android:layout_width="88dp"
android:layout_height="wrap_content"
android:layout_marginBottom="5dp"
android:layout_marginTop="5dp"
android:gravity="center"
android:text="#string/color_name"
android:textSize="15sp" />
</LinearLayout>
Issue occurred when I updated the gridview adapter from:
gridView = inflater.inflate(R.layout.mobile, null);
to
gridView = inflater.inflate(R.layout.mobile, parent, false);
so I just reversed back using a try catch if the old (null) version failed.
Try to change this:
android:layout_height="fill_parent"
into
android:layout_height="wrap_content"
You are now telling your grid view to fill it's parent height and width fully.
Here is my answer:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#id/linearLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<GridView
android:id="#+id/gridView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:columnWidth="100dip"
android:gravity="center"
android:numColumns="3"
android:stretchMode="spacingWidthUniform"
android:verticalSpacing="10dip" />
</LinearLayout>
Don't use padding or horizontalSpacing if you don't need it as it may cause problems with other views.
Note also that fill_parent is already deprecated.
I hope this will solve your problem:
<LinearLayout
android:layout_gravity="center_horizontal"
android:gravity="center"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<GridLayout
android:id="#+id/gridlayou4x3"
android:rowCount="4"
android:columnCount="3"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="80"
android:minWidth="25px"
android:minHeight="25px" />
</LinearLayout>
I found that you just have the gridlayout wrap content on height and width.
android:layout_centerHorizontal="true"
It will center itself for the size it needs but if you have it matching the parent. You are technically centering it based with a lot of parent empty space offsetting your children.
